1971 Jeep Truck Tire Fitment Guide

1971 Jeep Truck vehicles use four sizes: 700-16, F78-15, H78-15, and 750-16. All four apply to the Truck model, but they do not all mount on the same wheel diameter. The 700-16 and 750-16 fit 16-inch rims, while F78-15 and H78-15 fit 15-inch rims. Rim width guidance appears on some products: 700-16 commonly fits 4.50 to 5.50-inch rims, H78-15 fits 5.50 to 7.00-inch rims, and 750-16 fits 5.00 to 6.00-inch rims.

That means a 1971 Jeep Truck owner should confirm the wheel diameter already on the truck before worrying about sidewall style or brand. If your truck still has its original-type wheels, the tire size often follows that wheel package, but older trucks are frequently changed over the years. Once wheel diameter is confirmed, you can narrow the choice to the correct size family and then decide whether a blackwall or wide whitewall better fits the truck's intended look and use.

On a 1971 Jeep Truck, 700-16 is a numeric bias-ply size. The 7.00 refers to the tire's nominal section width in inches, with the decimal usually omitted in the sidewall code, and the 16 identifies the rim diameter in inches. This is an older American sizing system commonly seen on trucks and utility vehicles before later alphanumeric and metric conventions became common.

For a buyer, 700-16 immediately tells you that the tire is meant for a 16-inch wheel and carries a traditional bias-ply profile. It does not automatically make it interchangeable with every other 16-inch tire on a 1971 Jeep Truck, because 750-16 is also a 16-inch size but represents a different nominal section width. Confirming the exact size already fitted, or the wheel and clearance your truck uses, is the safest way to stay on the right path.

On a 1971 Jeep Truck, H78-15 is an alphanumeric bias-ply size. The H78 portion identifies the tire's load and section class within the older alphanumeric system, while the 15 marks the rim diameter in inches. Because there is no R in the code, it is a bias-ply designation rather than a radial one.

That matters because a 1971 Jeep Truck with H78-15 tires needs a 15-inch wheel, not a 16-inch truck wheel used by 700-16 or 750-16 fitments. H78-15 also tends to represent a larger alphanumeric truck or passenger-truck style fitment than F78-15. If your truck already wears 15-inch wheels, this code helps separate the correct tire family before you compare whitewall styling, load figures, or brand preferences.

1971 Jeep Truck tires are available in both blackwall and wide whitewall styles, depending on size. The 700-16 and 750-16 sizes each offer both blackwall and wide whitewall choices, while H78-15 also appears in both styles. That gives the 1971 Jeep Truck owner a real visual choice within the same basic period construction, rather than forcing a move to a different type of tire just to change appearance.

Blackwalls usually suit a more work-oriented Jeep truck look, especially for trucks restored with a utility or off-road character in mind. Wide whitewalls lean more toward a personalized, dress-up, or street-driven presentation. Since 1971 Jeep Truck pickups have often been restored in different directions, sidewall style can affect the truck's final personality almost as much as the wheel itself, so it is worth deciding early whether authenticity, utility, or visual flair is the goal.

Several brands cover 1971 Jeep Truck fitments. The 700-16 size is available from Lester, Avon, BFGoodrich, and Firestone. H78-15 is available from Coker Classic and STA, while 750-16 is available from Firestone, Lester, and BFGoodrich. All of those options stay within a vintage-style bias-ply approach rather than shifting the truck into a modern metric radial category.

Brand choice on a 1971 Jeep Truck usually comes down to the size you need first, then the look and character you want second. Some owners gravitate to familiar historic American names like Firestone and BFGoodrich for a traditional visual match, while others focus more on sidewall treatment or truck-oriented tread character. Once your correct size is settled, comparing brand by sidewall style and load rating is usually more useful than chasing a name alone.

For 1971 Jeep Truck vehicles using H78-15, Coker Classic and STA cover somewhat different visual and load-use priorities. Coker Classic appears in wide whitewall form with a 1,770-pound load rating at 32 psi and fits 5.50 to 7.00-inch rims. STA Traxion uses a blackwall truck-style presentation, carries a 1,830-pound load rating at 45 psi, and also fits 5.50 to 7.00-inch rims.

That makes the choice fairly straightforward for a 1971 Jeep Truck owner. If the truck is being restored with a more dressy period look, the Coker Classic whitewall options fit that visual goal while staying in the correct size family. If the truck is meant to emphasize utility appearance and a heavier-duty bias-ply character, the STA Traxion points in that direction. The wheel fit range stays the same, so the visual and load-pressure character become the main differences.

Rim width guidance for 1971 Jeep Truck tires varies by size. The 700-16 size commonly fits 4.50 to 5.50-inch rims, H78-15 fits 5.50 to 7.00-inch rims, and 750-16 fits 5.00 to 6.00-inch rims. Those ranges are important because bias-ply tires are sensitive to wheel width, and the wrong wheel can change the tire's profile and the way it sits on the truck.

A buyer should treat wheel width as a real fitment checkpoint rather alongside diameter. Two tires may both fit the same rim diameter, but if the wheel width falls outside the tire's approved range, the result can look wrong and drive poorly. Measuring the wheel you already have, especially on a truck that may have been changed over decades of use, is a smart step before choosing between the 15-inch and 16-inch tire families.

Tube requirements are not uniform across every 1971 Jeep Truck product, and some tires do not carry an explicit tube-type or tubeless marking in the size description. Because of that, tube use should be confirmed against the specific tire's sidewall marking and the wheel itself. On older truck wheels, the condition and design of the rim can matter just as much as the tire when deciding whether a tube is appropriate.

That is especially relevant on a 1971 Jeep Truck because many original and replacement wheels have lived hard lives, and surface condition, bead-seat shape, and prior repairs all affect setup decisions. If your truck still uses vintage-style steel wheels, inspect them carefully before mounting new tires. A Jeep specialist or experienced vintage tire installer can help determine whether your exact wheel and tire combination should run with tubes, without relying on guesswork.

Original 1971 Jeep Truck wheels cannot automatically be assumed to work with all four sizes, because the truck used both 15-inch and 16-inch tire fitments. A 15-inch wheel can only accept F78-15 or H78-15, while a 16-inch wheel can only accept 700-16 or 750-16. Within those diameter groups, rim width still needs to fall within the acceptable range for the specific tire you choose.

That means wheel diameter should be verified first, then wheel width second. If your truck has been restored, lifted, or swapped over the years, the wheels currently on it may not match the tire size it left the factory with. Once you know the wheel dimensions, you can narrow the choices quickly and avoid ordering a tire that is correct in era and style but wrong for the wheel actually on the vehicle.

A 1971 Jeep Truck should be stored in a cool, dry, dark place with the tires kept away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Tire pressures should be kept at a proper stored level, and the truck should either be moved periodically or supported in a way that reduces long-term static loading. Bias-ply tires are especially prone to flat-spotting when they sit in one position for long stretches.

That matters more with a vintage truck than with a modern daily driver because collector vehicles often spend weeks or months parked between outings. If your 1971 Jeep Truck sits for part of the year, occasional rolling movement and a clean, dry storage area will do more for tire life than simply covering the truck. Good storage habits also help preserve whitewalls, which can discolor or weather faster if they are left in harsh light and damp conditions.

Tires on a 1971 Jeep Truck are best judged by age and condition rather than mileage alone. A collector truck may see very few miles but still reach the point where the rubber hardens, the casing ages, or the sidewalls begin to crack. As a rule of thumb, tires deserve close evaluation once they reach about five to seven years of age, and replacement should be seriously considered as they approach ten years, regardless of tread depth.

The practical step is to check the DOT date code on the tire and combine that age information with a visual inspection. A 1971 Jeep Truck used only for shows or weekend drives can hide aging problems because the tread may still look healthy. If the truck has older tires of uncertain age, replacing them before a season of regular use is usually a wiser move than trying to squeeze extra years out of low-mileage rubber.

Tires on a 1971 Jeep Truck should be inspected before every drive and given a more thorough check before any longer outing. Look for sidewall cracking, cuts, bulges, uneven tread wear, signs of impact damage, and any pressure loss from one trip to the next. Since vintage truck tires may be paired with older wheels and hardware, valve stems and bead areas also deserve a close look during routine checks.

This habit is especially important on a low-use 1971 Jeep Truck because problems often develop while the truck is parked rather than while it is being driven. A quick walkaround can catch a weathered sidewall or a slow leak before it turns into a roadside issue. If the truck carries a spare for longer trips, inspect that tire too, because an old or underinflated spare is often the part of the package owners forget.

A 1971 Jeep Truck Truck would have been equipped in the bias-ply era reflected by the available sizes for the model: 700-16, F78-15, H78-15, and 750-16 are all bias-ply fitments. That aligns with the period, when utility pickups like Jeep's full-size trucks still commonly used bias-ply construction. The exact size could vary with wheel package and how the truck was configured when new, so a single size should not be assumed across every surviving example.

For a restoration, that means the first goal is matching the truck to the correct size family and wheel diameter, then choosing a sidewall style that suits the way the truck was originally presented. A blackwall often fits a more utilitarian truck character, while a whitewall points toward a more dressed-up period look. Factory literature, original owner paperwork, and Jeep marque specialists are the best resources for confirming the exact new-car presentation of an individual truck.

Correct tire fitment matters on a 1971 Jeep Truck because judges and knowledgeable enthusiasts often notice tire size, construction type, and sidewall treatment immediately. A truck restored for originality generally looks more convincing with the proper bias-ply construction and an era-appropriate sidewall style than it would with a visibly modern substitute. Wheel diameter also matters, since a 15-inch and 16-inch setup create distinctly different visual proportions.

That does not mean every show requires the same standard, but it does mean your tire choice should match your restoration goal. A local driver-quality truck can leave more room for personal taste, while a concours-style build benefits from closer research into factory-style size and appearance. Event rules vary, so Jeep clubs, factory brochures, and class-specific judging standards are worth checking before finalizing the tire that will define the truck's stance and presentation.

For 1971 Jeep Truck vehicles in 750-16, Firestone and BFGoodrich share the same basic vintage bias-ply construction but differ in presentation and some published load details. Firestone appears in blackwall and wide whitewall form with a 1,660-pound load rating at 40 psi and a 5.00 to 6.00-inch rim fit range. BFGoodrich appears in wide whitewall form with a 1,850-pound load rating at 48 psi and the same 5.00 to 6.00-inch rim range.

That gives a restorer a meaningful choice without leaving the proper size family. If a blackwall 750-16 suits the intended look of your 1971 Jeep Truck, Firestone covers that need directly, while both brands support a more presentation-oriented whitewall appearance. Because both mount on the same rim width range, the decision often comes down to sidewall styling and the load-pressure profile that best fits how the truck will be displayed or driven.

1971 Jeep Truck tires can be suitable for highway use when they are the correct size, in good condition, properly inflated, and used within their intended load and speed capability. One 700-16 commercial-spec option carries an L speed symbol, which corresponds to 75 mph. The other available sizes here are traditional bias-ply collector and truck tires, so the practical limit is often shaped as much by the truck's age, steering feel, braking system, and suspension design as by any raw speed number.

A well-sorted 1971 Jeep Truck can handle normal road use comfortably, but it should still be driven like a vintage truck rather than a modern pickup. Bias-ply tires can track road grooves differently and may feel less settled than modern radials at speed. Before regular highway driving, make sure the entire vehicle is roadworthy and choose a tire whose load and service character match the way the truck will actually be used.

Inflation pressure for a 1971 Jeep Truck depends on the exact size and product. Published maximum load-pressure figures include 700-16 at up to 1,900 pounds at 36 psi on some products, H78-15 at 1,770 pounds at 32 psi or 1,830 pounds at 45 psi depending on tire, and 750-16 at 1,660 pounds at 40 psi or 1,850 pounds at 48 psi depending on tire. Those figures describe the tire's rated load at a stated pressure, not necessarily the pressure your truck should run day to day.

The best approach is to start with the original owner's manual or factory vehicle placard for vehicle-spec inflation guidance, then confirm that recommendation against the reproduction tire's own markings and manufacturer guidance. Do not transfer a pressure figure from one 1971 Jeep Truck size to another just because both are bias-ply tires. Tire size, load rating, and intended use all influence the final pressure that makes sense for your particular truck.

Before a longer drive in a 1971 Jeep Truck, inspect each tire for sidewall cracks, cuts, tread separation, bulges, punctures, and irregular wear, then verify pressure when the tires are cold. Check the spare as carefully as the four road tires, because an old truck spare is often the weakest tire on the vehicle. If your setup uses older serviceable wheels or tube-compatible construction, look closely at valve stems and any signs of air loss around the wheel area.

Tires are only one part of the pre-trip checklist on a vintage Jeep truck, but they are the part that carries the whole vehicle. A truck that feels fine around town can still expose weak rubber once heat builds on a longer run. Pair the tire check with a quick review of brakes, steering, wheel bearings, and fluids so the truck is prepared for sustained use rather than just a short local outing.
