GMC Vandura Tires

GMC Vandura was part of the full-size American van movement of the 1970s, serving as a work-focused platform that could be configured for cargo duty, passenger use, and heavier commercial applications from 1971 through 1979. That broad mission matters when choosing tires, because GMC Vandura did not stay with one simple wheel and tire setup across the run. The listings show multiple passenger-car and truck-oriented sizes, several construction naming systems, and a mix of 14-inch, 15-inch, and 16.5-inch wheel applications in the same generation. The first step with any GMC Vandura is to confirm the actual rim diameter on the van before narrowing down the correct tire size.

GMC Vandura Tire Size Guide

GMC Vandura used 18 distinct tire sizes across the 1971 to 1979 production span, and the most important fitment fact is that wheel diameters varied across the range at 14 inches, 15 inches, and 16.5 inches from the start rather than changing in a single model-year break. GMC Vandura also used several different size conventions during these years, including numeric bias-ply, alphanumeric bias-ply, and alphanumeric radial sizing. That mix usually reflects different load ranges, wheel packages, and passenger-versus-heavier-duty applications, so the size on the sidewall and the wheel itself both need to agree.

C78-141971Alphanumeric bias-ply

C78-14 fits 1971 GMC Vandura applications and appears as an early 14-inch alphanumeric passenger size. The letter C identifies a narrower alphanumeric width class, 78 is the aspect-series convention used in period sizing, and 14 is the rim diameter in inches. Choose C78-14 only if the van still carries that 14-inch wheel setup, and because it is a non-radial alphanumeric bias-ply size, a tube is required.

E78-141971-1974Alphanumeric bias-ply

E78-14 applies to 1971 through 1974 GMC Vandura models using a 14-inch wheel. The letter E identifies the alphanumeric width class, 78 is the series designation, and 14 is the rim diameter; available products in this size use 14-inch rims. Choose E78-14 for vans equipped with this lighter 14-inch passenger-type setup, and because the listed construction is bias-ply without tubeless wording across the group, a tube is required.

F78-141971-1974Alphanumeric bias-ply

F78-14 fits 1971 through 1974 GMC Vandura applications on 14-inch wheels. The letter F marks the width class, 78 is the period aspect-series code, and 14 is the rim diameter; the available product in this size is built for a 14-inch rim. Choose F78-14 when the van's original wheel and stance call for this 14-inch bias-ply size, and a tube is required.

700-141971-1974Numeric bias-ply

700-14 is used on 1971 through 1974 GMC Vandura models with 14-inch wheels. In numeric bias-ply sizing, 700 indicates a nominal 7.00-inch section width and 14 is the rim diameter; the listed products specify 14-inch rims. Choose 700-14 when the van is set up for this numeric 14-inch bias-ply fitment, and a tube is required.

G78-151971-1977Alphanumeric bias-ply

G78-15 fits GMC Vandura models from 1971 through 1977 using a 15-inch wheel. The letter G identifies the alphanumeric width class, 78 is the series designation, and 15 is the rim diameter; available products for this size are built for 15-inch rims. Choose G78-15 when the van carries this 15-inch passenger or light truck bias-ply setup, and a tube is required.

H78-151971-1974Alphanumeric bias-ply

H78-15 applies to 1971 through 1974 GMC Vandura applications with 15-inch wheels. The letter H marks a wider alphanumeric class than G, 78 is the series code, and 15 is the rim diameter; the products for this size use 15-inch rims. Choose H78-15 for vans equipped with this wider 15-inch bias-ply fitment, and a tube is required.

800-16.51971-1979Numeric bias-ply

800-16.5 fits GMC Vandura models across the full 1971 through 1979 run where 16.5-inch wheels were used. In numeric bias-ply sizing, 800 indicates a nominal 8.00-inch section width and 16.5 is the rim diameter; available products confirm the 16.5-inch wheel. Choose 800-16.5 for heavier-duty GMC Vandura wheel packages using 16.5-inch rims, and a tube is required.

875-16.51971-1979Numeric bias-ply

875-16.5 is listed for GMC Vandura from 1971 through 1979 on 16.5-inch wheels. The 875 code indicates a nominal 8.75-inch section width in numeric bias-ply form, while 16.5 is the wheel diameter; the listed products use 16.5-inch rims. Choose 875-16.5 when the van has the wider heavy-duty 16.5-inch setup, and a tube is required.

670-151972-1974Numeric bias-ply

670-15 fits 1972 through 1974 GMC Vandura applications using 15-inch wheels. In numeric bias-ply sizing, 670 indicates a nominal 6.70-inch section width and 15 is the rim diameter; all listed products for this size use 15-inch rims. Choose 670-15 when the van is set up for this narrower 15-inch bias-ply fitment, and a tube is required.

HR78-151972-1974, 1978-1979Alphanumeric radial

HR78-15 appears on GMC Vandura in 1972 through 1974 and again in 1978 through 1979 as a 15-inch radial fitment. The letter H identifies the width class, R indicates radial construction, 78 is the series code, and 15 is the rim diameter in inches. Choose HR78-15 only when the van is already matched to this 15-inch radial-style sizing and wheel package.

950-16.51972-1974Numeric bias-ply

950-16.5 fits 1972 through 1974 GMC Vandura applications using the largest listed 16.5-inch wheel package. The 950 code indicates a nominal 9.50-inch section width and 16.5 is the rim diameter; available products confirm 16.5-inch rims. Choose 950-16.5 for GMC Vandura heavy-duty use where this larger 16.5-inch bias-ply size is specified, and a tube is required.

C78-151975-1977Alphanumeric bias-ply

C78-15 is listed for 1975 through 1977 GMC Vandura applications on 15-inch wheels. The letter C identifies a narrower alphanumeric width class, 78 is the period series convention, and 15 is the rim diameter. Choose C78-15 only if the van carries this specific 15-inch bias-ply fitment, and a tube is required.

E78-151975-1977Alphanumeric bias-ply

E78-15 fits 1975 through 1977 GMC Vandura models using 15-inch wheels. The letter E identifies the width class, 78 is the series code, and 15 is the rim diameter in inches. Choose E78-15 for vans built around this 15-inch bias-ply size, and a tube is required.

F78-151975-1977Alphanumeric bias-ply

F78-15 applies to 1975 through 1977 GMC Vandura applications with 15-inch wheels. The letter F marks the width class, 78 is the aspect-series designation, and 15 is the wheel diameter. Choose F78-15 when the van retains that specific 15-inch bias-ply configuration, and a tube is required.

GR78-151975-1979Alphanumeric radial

GR78-15 is listed for 1975 through 1979 GMC Vandura models using 15-inch wheels. The letter G identifies the width class, R indicates radial construction, 78 is the series code, and 15 is the rim diameter. Choose GR78-15 when the van is set up for a 15-inch radial-type fitment rather than a same-diameter bias-ply alternative.

J78-151975-1979Alphanumeric bias-ply

J78-15 fits 1975 through 1979 GMC Vandura applications using a 15-inch wheel. The letter J identifies a wider alphanumeric width class, 78 is the series code, and 15 is the rim diameter; the listed products in this size use 15-inch rims. Choose J78-15 when the van carries this wider 15-inch bias-ply setup, and a tube is required.

JR78-151975-1979Alphanumeric radial

JR78-15 appears on 1975 through 1979 GMC Vandura models with 15-inch wheels. The letter J identifies the width class, R marks radial construction, 78 is the series code, and 15 is the rim diameter. Choose JR78-15 when the van is built around this wider 15-inch radial sizing rather than a bias-ply J78-15 application.

FR78-151978-1979Alphanumeric radial

FR78-15 fits 1978 and 1979 GMC Vandura applications using 15-inch wheels. The letter F identifies the width class, R indicates radial construction, 78 is the series code, and 15 is the rim diameter. Choose FR78-15 only for late GMC Vandura applications using this 15-inch radial fitment.

8.75R16.51978-1979Metric radial

8.75R16.5 appears on 1978 and 1979 GMC Vandura as a 16.5-inch radial truck size. The 8.75 figure denotes the nominal section width, R indicates radial construction, and 16.5 is the rim diameter in inches. Choose 8.75R16.5 only when the van has the later 16.5-inch radial wheel and tire specification rather than the bias-ply 875-16.5 size.

Buyers with a 1972, 1973, 1974, 1975, 1976, 1977, 1978, or 1979 GMC Vandura should identify the exact configuration before selecting a tire, because those years include multiple fitments spanning 14-inch, 15-inch, and 16.5-inch wheel packages as well as both bias-ply and radial constructions.

GMC Vandura Tires by Year

The year listing helps narrow GMC Vandura tire choices by showing which sizes were used in each model year. In 1971 through 1979, more than two sizes are listed in every year, reflecting a mix of passenger, heavier-duty, and construction-specific applications. GMC Vandura covers 14-inch, 15-inch, and 16.5-inch wheel packages, so the actual wheel diameter should be confirmed before matching a year to a tire size.

Best GMC Vandura Tires for Sale

Available GMC Vandura tire listings include 8 brands across 45 products, covering 11 of the listed sizes from 14-inch, 15-inch, and 16.5-inch applications. Confirm the correct size and wheel diameter on the van before choosing, especially where passenger and truck-type fitments overlap.

Frequently Asked Questions

These GMC Vandura FAQs sort out the real points of confusion: multiple wheel diameters in the same generation, bias-ply versus radial size formats, and the difference between passenger-style and heavier-duty van tire listings.

Size Basics & Fitment

GMC Vandura uses a wide range of sizes across 1971 to 1979. The 14-inch listings are C78-14, E78-14, F78-14, and 700-14. The 15-inch listings are 670-15, G78-15, H78-15, C78-15, E78-15, F78-15, J78-15, HR78-15, GR78-15, JR78-15, and FR78-15. The 16.5-inch listings are 800-16.5, 875-16.5, 950-16.5, and 8.75R16.5.

That spread means year alone is not enough to choose a tire for GMC Vandura. Some years include passenger-style 14-inch or 15-inch fitments while others also include heavier-duty 16.5-inch truck applications, and several late-year 15-inch sizes appear in both bias-ply and radial form. The practical path is to match the model year, then verify the tire size already on the van and the actual wheel diameter before deciding between available products.

A 700-14 GMC Vandura tire uses the older numeric bias-ply system. The 700 portion means a nominal 7.00-inch section width, and the 14 means the tire fits a 14-inch rim. For GMC Vandura, this size is listed from 1971 through 1974 and the available products are bias-ply tires built for 14-inch wheels.

Numeric sizes like 700-14 are easy to confuse with later metric or radial sizing, so the sidewall needs to be read carefully. On GMC Vandura, 700-14 belongs to an early 14-inch application and should not be treated as interchangeable with 15-inch or 16.5-inch listings. If the van still wears older wheels, compare the sidewall marking and wheel diameter together before choosing a replacement.

A 1972 GMC Vandura has 10 tire sizes listed because GMC offered more than one wheel diameter and more than one type of service application in the same model year. That year includes 14-inch sizes, 15-inch sizes, and 16.5-inch truck-type sizes, and it also includes both bias-ply and radial-style alphanumeric sizing. The variety reflects configuration differences rather than one universal tire choice for every van.

The key implication is that a 1972 GMC Vandura owner has to identify the exact wheel and tire setup on the van, not just the year on the title. A van used for passenger service, custom use, or heavier cargo duty may land on a different size family. Start with the wheel diameter, then compare the current sidewall code to the year listing to narrow the correct replacement.

GMC Vandura uses three rim diameters across these listings: 14 inches, 15 inches, and 16.5 inches. Early and mid-1970s applications include both 14-inch and 15-inch passenger-style sizes, while heavier-duty applications span 16.5-inch sizes through the full 1971 to 1979 run. The size code itself usually includes the wheel diameter on these Vandura listings, such as 14, 15, or 16.5 at the end of the designation.

That makes wheel measurement the first real fitment step on GMC Vandura. A 15-inch tire will not substitute for a 16.5-inch wheel, and late radial versions such as 8.75R16.5 still require the same 16.5-inch rim even though the format looks different. If the van has changed hands or has had wheels swapped over the years, confirm the stamped wheel size before selecting tires.

Buying the Right Tire

A 1975 GMC Vandura can use several different sizes, including 15-inch passenger-style fitments such as C78-15, E78-15, F78-15, G78-15, GR78-15, J78-15, and JR78-15, plus 16.5-inch sizes such as 800-16.5 and 875-16.5. That means the correct size is tied to the actual wheel and configuration on the van rather than the model year alone.

The most reliable approach is to read the full size code on the tire already fitted, then confirm the wheel diameter before matching it to a replacement. GMC Vandura can also present a bias-ply versus radial choice within the same general wheel diameter, so the sidewall construction marking matters as much as the year. For a restored or long-owned van, original paperwork and wheel stamps can help settle any ambiguity.

GMC Vandura tire listings include blackwall, narrow whitewall, wide whitewall, and dual-white-stripe sidewall styles. The mix depends on size: some 14-inch and 15-inch passenger-oriented sizes show multiple whitewall choices, while the 16.5-inch truck-style sizes in these listings are blackwall. J78-15 also appears with both a narrow whitewall and a dual-white-stripe treatment.

That variety matters most on custom, survivor, and period-correct vans where sidewall appearance changes the look as much as the size itself. Whitewall and stripe options usually suit more passenger-focused or styled builds, while blackwalls make more sense on utility-oriented GMC Vandura applications and the heavier 16.5-inch sizes. Match the sidewall style to the van's era, trim intent, and the type of wheel package it actually carries.

The listed GMC Vandura tire brands include Coker Classic, STA, BFGoodrich, Firestone, US Royal, Universal Vintage Tire, Excelsior, Avon, and Goodyear. Brand coverage varies by size. Some sizes have only one or two brand options, while 670-15 has the broadest spread with multiple blackwall and whitewall choices across several classic tire lines.

Brand choice on GMC Vandura is often driven by the size and the style of restoration rather than by name alone. A passenger-oriented whitewall van may point toward one set of brands and series, while a heavier-duty 16.5-inch blackwall application may narrow the field quickly. It makes sense to confirm size first, then compare sidewall style, construction, and series within that size family.

GMC Vandura listings include several series names, among them Coker Classic Bias Ply, Silvertown Classic Bias Ply, Firestone Classic Bias Ply, US Royal Classic Bias Ply, Universal Classic Bias Ply, Excelsior Bias Ply, Traxion, Super Traxion, Super Transport, Transport Highway, Super Cushion, Custom Super Cushion, Super Cushion Deluxe, and Turbospeed Mk4. Some series are styled passenger-car bias-ply offerings with whitewall choices, while others are more truck-oriented blackwall patterns intended for heavier service.

For GMC Vandura, the practical difference is usually appearance, use case, and construction family within a given size. A whitewall bias-ply series fits a passenger or custom presentation, while the STA truck-family series suits the utility-oriented 14-inch, 15-inch, and 16.5-inch work-type applications. Once the correct size is established, the right series comes down to whether the van is being restored for period appearance, commercial character, or heavier-duty use.

Maintenance & Longevity

A GMC Vandura should be stored on a clean, dry surface away from direct sunlight, ozone sources, and prolonged contact with petroleum products. Tires last better when the van is kept indoors, inflation is maintained, and the load is not left concentrated on one spot for months at a time. Collector vans also benefit from occasional movement to avoid flat spotting and sidewall stress.

If a GMC Vandura will sit for a long season, many owners reduce strain by moving the van periodically or supporting it so the tires are not carrying full weight continuously. Bias-ply tires are especially prone to temporary flat spotting after storage, so a gentle warm-up drive is wiser than immediate highway use. Good storage habits preserve both appearance and service life on low-use collector tires.

Tires on a GMC Vandura should be inspected before regular driving and again after long storage periods. Check inflation, tread condition, sidewall cracking, bulges, bead seating, and any evidence of uneven wear. On heavier-duty Vandura applications, also look closely for stress from load use, curb damage, or long periods of standing with cargo weight on the tires.

Frequent inspection matters because collector vans often age out of their tires before they wear them out. A GMC Vandura that is used only for shows, cruises, or occasional hauling can still develop age-related issues that are not obvious from tread depth alone. Making inspection part of every pre-drive routine is one of the simplest ways to catch problems before they become road failures.

A GMC Vandura tire should be replaced when it shows age cracking, cord exposure, impact damage, bulging, persistent air loss, or other structural concerns even if the tread still looks usable. Collector-vehicle tires can deteriorate from time, storage conditions, and heat cycles long before the tread is worn down. Tread depth alone is never a complete measure of tire condition on an older van.

That matters even more on a GMC Vandura because many vans are driven intermittently and may appear mechanically ready after long storage. A tire that looks presentable at a glance can still be unsafe because of internal age or sidewall fatigue. Replacement decisions should be guided by overall condition, age, and intended use, especially before carrying passengers, highway cruising, or putting weight in the van.

Restoration & Authenticity

GMC Vandura was fitted across a broad spread of 14-inch, 15-inch, and 16.5-inch sizes during 1971 to 1979, including both numeric and alphanumeric bias-ply sizes and later radial-style designations. The available series in these listings range from classic passenger bias-ply lines to truck-oriented patterns such as Traxion, Super Traxion, Super Transport, and Transport Highway. That breadth shows there was not one single original tire answer for every GMC Vandura.

For restoration work, the correct tire on a specific GMC Vandura comes down to the exact year, wheel diameter, and intended configuration of the van. A custom passenger van, a work van, and a heavier-duty application may all point to different original-style directions. Factory literature, build records, and marque specialists remain the best references when authenticity matters more than simple replacement.

Correct tire fitment can affect both the presentation and the judged authenticity of a GMC Vandura. Size, sidewall style, and construction all influence whether the van looks period-appropriate, and a mismatched wheel diameter or visibly modern substitute can stand out quickly. On custom-era vans and well-restored originals alike, tires are a visible part of the overall statement.

For a GMC Vandura being prepared for show judging or serious resale, tire choice should match the restoration goal rather than convenience alone. Passenger-style whitewalls, blackwalls, stripe treatments, and truck-duty tread patterns each send a different message about the van's intended character. Marque clubs, period photos, and original sales material are useful checks when you want the stance and appearance to support the rest of the restoration.

A GMC Vandura restoration can reasonably point to blackwall, narrow whitewall, wide whitewall, or dual-white-stripe tires depending on the size and the type of build. The available listings show that whitewall choices are concentrated in several 14-inch and 15-inch passenger-oriented sizes, while the 16.5-inch heavy-duty sizes are blackwall. J78-15 also offers a stripe-style look through a dual-white-stripe version.

The right sidewall on GMC Vandura depends on whether the van is being restored as a work vehicle, a passenger van, or a period custom. A blackwall usually fits a more utilitarian presentation, while whitewalls or stripes suit styled and upscale 1970s van themes. The smartest choice is the one that matches the van's original character and the wheel size it actually uses.

Safety & Road Use

These GMC Vandura tires can be appropriate for public-road use when the size, wheel diameter, and construction match the van correctly and the tires are in sound condition. The listings include both passenger-style bias-ply choices and heavier-duty truck-type tires, so road suitability depends on selecting the right family for the van's actual setup. Safe use begins with correct fitment, proper inflation, and a tire that is structurally healthy.

For a GMC Vandura, the practical issue is not whether a tire looks close, but whether it matches the wheel and intended load service. A 16.5-inch heavy-duty van should stay within the correct 16.5-inch category, and a passenger-style 15-inch build should use the size and construction intended for that wheel package. Any van returning to service after long storage deserves a full inspection before regular road driving.

Before driving a GMC Vandura, check tire pressure, sidewall condition, tread condition, visible age cracking, valve stems, wheel security, and whether all four tires match the intended setup. Also verify that the wheel diameter agrees with the tire size marking, especially on vans that could be fitted with 14-inch, 15-inch, or 16.5-inch wheels. On work-oriented vans, load condition matters as much as appearance.

A short pre-drive check is especially important on GMC Vandura because many surviving vans are seasonal vehicles that spend long periods parked. Bias-ply tires can develop flat spots and age-related stiffness, while long-stored wheels and brakes may also need attention before any serious outing. A cautious first drive after storage should be local and gradual rather than an immediate high-speed trip.

A sensible speed for a GMC Vandura on original-style tires depends on the exact tire construction, age, condition, load, and wheel package. Bias-ply tires generally reward a more conservative approach than modern everyday vehicle tires, and heavily loaded 16.5-inch van applications deserve even more caution. Safe speed starts with respecting the limitations of a vintage-style tire and the mechanical condition of the van itself.

For most collector-use GMC Vandura driving, moderate speeds that suit the road, the load, and the tire's condition are wiser than trying to treat the van like a modern highway appliance. Freshly inspected tires, correct inflation, and matched construction across the axle all help stability. If the van is on older tires of uncertain age, keep speeds down until a specialist has evaluated the full setup.
