1972 GMC Vandura Tires

A 1972 GMC Vandura does not use one universal tire size across the entire lineup. Primary fitments include 700-14, E78-14, F78-14, 670-15, G78-15, H78-15, HR78-15, 800-16.5, 875-16.5, and 950-16.5, depending on whether the van is a G1500, G2500, or G3500 and on its GVWR range.

The most important step is identifying the exact Vandura series and confirming the wheel diameter already on the van. A G1500 usually stays in the 14-inch group, many G2500 versions use 15-inch fitments, and G3500 models move into 16.5-inch truck sizes. On vans that have been modified or serviced over the years, checking the actual wheel and tire markings is just as important as checking the model designation.

A 1972 GMC Vandura can use 14-inch, 15-inch, or 16.5-inch rims, depending on the sub-model and load rating. The 14-inch sizes are 700-14, E78-14, and F78-14. The 15-inch sizes are 670-15, G78-15, H78-15, and HR78-15. The heavy-duty 16.5-inch sizes are 800-16.5, 875-16.5, and 950-16.5.

Wheel diameter should be confirmed before comparing any tire options because the Vandura range spans three distinct rim diameters. That matters even more on restored, converted, or customized vans, where wheel swaps are common. The tire size molded into the current sidewall and the wheel measurement itself will help confirm whether the van belongs in the 14-inch, 15-inch, or 16.5-inch fitment group.

The 1972 GMC Vandura was offered in multiple series and GVWR configurations, so tire fitment changes with the role of the van. Lighter G1500 versions use 14-inch bias-ply sizes, G2500 models move into 15-inch sizes, and G3500 heavy-duty applications use larger 16.5-inch truck tires. One G2500 fitment also includes an HR78-15 radial application.

That range means tire selection is tied to the exact chassis specification rather than just the Vandura name. A family hauler, service van, or camper conversion may also have different wheels today than it did decades ago. Matching the correct size starts with the sub-model and GVWR, then moves to verifying the actual wheel diameter and confirming that the current setup has adequate clearance for the chosen tire.

HR78-15 is a radial tire size for the 1972 GMC Vandura. It uses the vintage alphanumeric radial format, where the R indicates radial construction, and it appears as a primary 15-inch fitment on one G2500 application rather than as a converted equivalent to a separate size.

That distinction matters because HR78-15 should not be treated as interchangeable with every other 15-inch Vandura tire. Nearby G2500 fitments also use 670-15, G78-15, or H78-15 bias-ply sizes, and those belong to different primary applications. Before ordering, confirm the exact sub-model, check the current wheel size, and make sure the van is being matched to the proper 15-inch construction and size family.

Radial equivalents for 670-15 include 195R15 as the 80-series metric radial option, P205/75R15 as the 75-series P-metric option, P215/70R15 as the 70-series P-metric option, and 670R15 as the bias-look radial equivalent. The recommended rim-width range associated with these equivalents is 5 to 7 inches.

Those choices give different sizing formats and visual character rather than one automatic replacement. The 195R15 keeps a traditional Euro-metric radial format, the P-metric options move into modern labeling, and the 670R15 keeps a more vintage-looking presentation. Any change from the original 670-15 bias-ply fitment should be checked against the van's wheel width, overall clearance, and current suspension and steering setup.

Start by confirming that a true radial equivalent exists for the original Vandura tire size, because equivalents are not shown for every primary size in the range. For example, 700-14, E78-14, F78-14, 670-15, G78-15, and H78-15 have radial equivalents, while the larger 16.5-inch truck sizes shown here remain bias-ply fitments.

After choosing the correct equivalent size, check wheel diameter, wheel width, tire clearance, and the van's intended load and road use. A radial alternative should also be evaluated against the current condition of the suspension and steering components, especially on older vans. The goal is to confirm that the tire works with the actual wheel and vehicle setup, not just that the nominal size looks close on paper.

The first consideration is the exact fitment group: G1500, G2500, or G3500, along with the van's GVWR and wheel diameter. A 1972 GMC Vandura can use 14-inch, 15-inch, or 16.5-inch tires, and those sizes span light-duty passenger-style bias-ply fitments, heavier truck-oriented bias-ply tires, and one primary 15-inch radial application.

Once the size is confirmed, compare the tire's construction, sidewall style, series, and intended character. Some sizes lean toward classic whitewall presentation, while others are available only as blackwall truck tires. It also helps to consider rim-width compatibility and load-related specifications where shown, especially on G2500 and G3500 applications that may still see hauling, conversion, or regular road use.

1972 GMC Vandura tire options include blackwall, narrow whitewall, and wide whitewall sidewall treatments, depending on the size. The 14-inch and 15-inch light- and medium-duty fitments show the broadest appearance range, while the heavier 16.5-inch truck sizes stay in blackwall form. Sidewall choice varies by the exact tire size rather than across the entire Vandura lineup.

That means appearance decisions should come after the correct fitment is identified. A G1500 or some G2500 applications may support a more traditional whitewall presentation, while a G3500 often points toward a commercial-style blackwall look. Sidewall style can change the van's visual character significantly, but it should always be treated as a secondary decision after size, wheel diameter, and construction are confirmed.

Brand coverage for the 1972 GMC Vandura includes BFGoodrich, Coker Classic, Firestone, Goodyear, US Royal, Universal Vintage Tire, Excelsior, Avon, and STA. Brand availability depends heavily on the specific tire size. The broadest selection appears in 670-15, while several other sizes have a much narrower range of product choices.

Comparing brands is most useful after narrowing the search to the correct size for the van. At that point, the real distinctions are often sidewall treatment, tire series, rim-width specifications, and whether the tire presents more as a classic passenger-style option or a truck-oriented design. Brand matters, but it should be considered alongside the tire's format and the Vandura's intended use rather than by name alone.

A period-style 1972 GMC Vandura tire choice starts with the correct primary size for the specific van, then stays within the visual language of that fitment. Many G1500 and some G2500 applications have classic bias-ply options with blackwall, narrow whitewall, or wide whitewall presentations, while the heavier G3500 models lean toward blackwall truck tires.

That approach keeps the van's appearance aligned with its role and stance without assuming one universal look across the entire Vandura range. For owners chasing exact restoration accuracy, size and construction are the first checkpoints, and sidewall treatment comes next. Marque-specific photos, dealer literature, and build-era references can help refine the final appearance choice once the proper fitment has been established.

Tire construction affects both stance and visual character on a restored 1972 GMC Vandura. Bias-ply tires usually maintain the traditional look associated with vintage van fitments, especially when paired with classic blackwall or whitewall sidewall treatments. A radial-format tire, including an alphanumeric radial or a modern equivalent, can change the visual impression even when the wheel diameter remains the same.

That does not make one construction universally right or wrong for restoration work. The decision depends on whether the goal is a more traditional presentation, a driver-focused setup, or a custom interpretation of the van. Construction should be considered alongside the correct size, wheel, and ride height, since appearance on a full-size 1972 van is shaped by the entire combination rather than the sidewall alone.

Yes, modifications can affect tire fitment on a 1972 GMC Vandura. Aftermarket wheels, suspension changes, altered ride height, body conversions, and steering-component changes can all influence which tire size actually works on the van. That matters especially here because the Vandura already spans 14-inch, 15-inch, and 16.5-inch fitments from the factory range.

A modified van should be checked as it sits today rather than assumed to match original specifications. Wheel diameter and width are the first checkpoints, followed by tire clearance at the fenders, inside the wheelhouses, and at full steering travel. On camper and custom builds, extra body weight and altered suspension geometry can also influence what tire size and construction make practical sense.

Before driving a 1972 GMC Vandura on new tires, inspect the wheels for the correct diameter and condition, verify proper mounting, and check inflation carefully. It is also wise to look over the steering and suspension, since worn components can affect how an older van feels on fresh tires. Lug hardware and valve stems should be in sound condition as well.

A short initial drive should include listening for rubbing and checking clearance through turns and suspension movement. On heavier G2500 and G3500 models, load-carrying expectations matter, so the tire should match the van's intended duty. After the first few miles, recheck inflation and give the tires a visual inspection to make sure seating, wear pattern, and general fitment all look normal.

Tires on a collector 1972 GMC Vandura should be kept properly inflated, inspected regularly, and protected from long periods of damaging storage conditions. Older vans often spend more time parked than driven, which makes sidewall cracking, flat spotting, and unnoticed air loss more important than many owners expect. Tread depth alone is not enough to judge condition.

Regular visual checks should include cuts, bulges, weathering, and uneven wear, along with a quick look at wheel condition and valve stems. Storage away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve low-use collector tires. Even a van driven only occasionally benefits from periodic movement and inspection, especially before a longer trip or after sitting through an off-season.
