Jeep CJ5 Tires

Jeep CJ5 uses four tire sizes across the years shown here: 7.35-15 for 1971 through 1973, F78-15 for 1971 through 1974, H78-15 for 1971 through 1974, and E78-15 for 1974. Every size in this group is built around a 15-inch wheel, but the size classes differ in section width and period labeling format. H78-15 is the size in this group with listed products, and those products are all bias-ply tires for 15-inch rims.

That means year alone is not enough to identify the right tire for every Jeep CJ5. Start with the actual size on the vehicle, then confirm the wheel diameter and compare the tire's width class to the vehicle's current wheel and intended use. If the Jeep has been restored or modified over time, the safest path is to verify the wheel and size together rather than assume the largest or most common option is correct.

A 7.35-15 tire on a Jeep CJ5 uses the older numeric bias-ply size system. The 7.35 figure is the nominal section width in inches, while the 15 indicates a 15-inch rim diameter. On the years shown here, 7.35-15 appears on 1971, 1972, and 1973 Jeep CJ5 applications, which places it among the earlier listed size options in this model range.

The practical takeaway is that 7.35-15 should be matched to a Jeep CJ5 that actually calls for that narrower numeric fitment, not simply any CJ5 with a 15-inch wheel. Numeric and alphanumeric period sizes can overlap in era but still represent different width classes. If the Jeep already wears a different size code, compare the wheel width and the vehicle's original specification before moving from one format to another.

A 1971 Jeep CJ5 has 7.35-15, F78-15, and H78-15 listed because more than one tire size was used within that model year. All three are 15-inch sizes, so the split is not a wheel-diameter change. Instead, it reflects configuration differences within the Jeep CJ5 line, with multiple period-correct width classes shown for the same year.

That makes the exact vehicle configuration more important than the calendar year by itself. Check the current wheel width, any surviving factory tire information, and the vehicle's equipment level before choosing among the listed sizes. For a restored Jeep CJ5, matching the original width class helps preserve the correct stance and steering feel, while for a driver, it helps avoid choosing a tire that is too narrow or too wide for the wheel.

The Jeep CJ5 sizes shown here are numeric and alphanumeric bias-ply fitments, and the listed H78-15 products are all bias-ply tires. In this period construction and sizing style, a tube is required. That applies to the sizes shown in this range, including 7.35-15, F78-15, H78-15, and E78-15.

Tube selection still needs to match the tire size and the wheel condition. A sound tube, flap where appropriate, and a clean wheel interior matter just as much as the outer tire on a collector or utility Jeep. If the wheels have been changed from original style, confirm that the wheel design is suitable for tube-type service before mounting new tires.

A 1974 Jeep CJ5 can use E78-15, F78-15, or H78-15, so the correct size depends on the specific configuration rather than the year alone. All three are 15-inch fitments, but they represent different width classes within the period alphanumeric system. Because 1974 carries the widest spread of listed alphanumeric sizes in this group, it deserves a closer check than a simple year lookup.

Begin with the size already mounted if the Jeep retains an established setup, then inspect the wheel width and compare it to the intended tire size. Original paperwork, surviving labels, and marque-specific references can help separate a narrow-base setup from a broader utility or truck-style application. That extra step keeps a 1974 Jeep CJ5 from ending up on a tire that fits the rim diameter but is wrong for the wheel width or look.

The listed Jeep CJ5 products in H78-15 include both wide whitewall and blackwall sidewall styles. Two Coker Classic H78-15 tires are offered with wide whitewalls, while the STA Traxion H78-15 is a blackwall bias-ply truck-oriented design. That gives Jeep CJ5 owners a choice between a more stylized period passenger-car appearance and a more utilitarian blackwall look within the same size.

For most utility-oriented Jeep CJ5 restorations and drivers, blackwall tires usually align more naturally with the model's working 4x4 character. Whitewalls can still suit a personalized build or a period-custom presentation, especially if the goal is a distinctive early-1970s look. The key is to match the sidewall style to the vehicle's intended character, since sidewall appearance changes the personality of a short-wheelbase Jeep as much as the tread itself.

The listed Jeep CJ5 products in this group come from two brands: Coker Classic and STA. Coker Classic appears with H78-15 wide whitewall bias-ply offerings in the Coker Classic Bias Ply series, while STA appears with the H78-15 Traxion blackwall bias-ply tire. Those are the brands represented among the currently listed products for Jeep CJ5 in this size group.

Brand choice should follow the type of Jeep CJ5 you are building. A vehicle aimed at period passenger-car styling may lean toward the Coker Classic whitewall offerings, while a more workmanlike or truck-influenced presentation may favor the STA Traxion. Before choosing a brand, confirm that the size, wheel width range, and sidewall style all support the finished look and function you want from the Jeep.

The listed Jeep CJ5 products include two tire series: Coker Classic Bias Ply and Traxion. Coker Classic Bias Ply is represented here by whitewall H78-15 tires with a more passenger-car-oriented appearance, while Traxion is represented by a blackwall H78-15 tire with a military and truck character. Both are bias-ply constructions, but they serve different visual and use-case roles within the same size.

That distinction matters because a Jeep CJ5 can be restored in more than one direction. If the goal is a period-correct utility look, the Traxion style may better suit the vehicle's 4x4 roots. If the Jeep CJ5 is being presented with a more polished vintage style, the Coker Classic Bias Ply whitewall options create a very different impression without changing the basic H78-15 size.

A stored Jeep CJ5 should be kept in a cool, dry, dark space with the tires protected from sunlight, ozone sources, and standing moisture. Bias-ply tires particularly benefit from stable inflation and relief from long-term point loading, because collector vehicles often sit for extended periods. Clean wheels and proper tube condition also matter when the Jeep remains parked seasonally or between events.

If the Jeep CJ5 will sit for months, move it occasionally to change the tire contact patch or support it in a way that reduces prolonged weight on one spot. Keep petroleum products away from the sidewalls, and avoid storing near motors, welders, or battery chargers that generate ozone. Good storage habits preserve both the tire's appearance and the way the Jeep drives when it returns to the road.

Tires on a Jeep CJ5 should be visually inspected before every drive and given a more thorough inspection several times a year, even if the vehicle covers very few miles. Collector and occasional-use tires age from time and environment as much as from tread wear. On a short-wheelbase 4x4, small issues such as sidewall cracking, air loss, or irregular wear can affect handling quickly.

A proper inspection on a Jeep CJ5 should include tread, sidewalls, valve stems, wheel condition, inflation pressure, and any signs of tube-related leakage or chafing. Also look for uneven wear that may point to alignment or suspension issues, especially on vehicles that see trail use or rough secondary roads. Frequent inspection is inexpensive insurance against turning a minor tire issue into a damaged wheel or roadside problem.

A Jeep CJ5 tire should be replaced when age, cracking, hardening, separation, flat-spotting that does not recover, or structural deterioration appears, even if tread depth still looks acceptable. Collector tires often age out before they wear out, particularly on vehicles driven only occasionally. Tubes, wheels, and mounting surfaces should be evaluated at the same time because a fresh outer tire cannot compensate for hidden age-related issues underneath.

That rule is especially important on a Jeep CJ5 because the vehicle's short wheelbase and utility use can make tire problems more noticeable in steering and ride. Replacement decisions should be driven by condition and age, not tread alone. If a tire has an uncertain service history or has spent years parked under load, treat it conservatively and have the assembly examined before putting the Jeep back into regular road use.

Jeep CJ5 appears here with 7.35-15, F78-15, H78-15, and E78-15 depending on year, with 1971 through 1973 carrying 7.35-15, F78-15, and H78-15, and 1974 carrying E78-15, F78-15, and H78-15. The listed product series for the available H78-15 options are Coker Classic Bias Ply and Traxion. That establishes the period-style sizes and series available in this range, but more than one fitment was used within the same years.

For restoration work, the right answer is the tire that matches the specific Jeep CJ5 configuration being recreated, not simply the broad model name. Factory literature, surviving original tires, and marque-club references are the best tools for separating a general period-correct size from the exact original setup. That extra effort matters if the Jeep is being judged or restored to a particular trim, use, or visual presentation.

Correct tire fitment can affect both the judged authenticity and the perceived value of a Jeep CJ5. Size, sidewall style, and overall stance all contribute to whether the vehicle looks properly restored for its year and configuration. A Jeep CJ5 wearing the wrong width class or an obviously mismatched sidewall treatment can look less convincing even if the tire physically fits the wheel.

That does not mean every collector Jeep CJ5 must be restored to the strictest factory standard, but it does mean the tire choice should match the goal of the build. A trail-oriented driver, a factory-style restoration, and a period custom may each justify different tire appearances. If authenticity matters, compare the selected tire against marque-club standards and period photos before finalizing the combination.

The available Jeep CJ5 sidewall styles shown here are wide whitewall and blackwall in H78-15. Blackwall generally aligns more naturally with the Jeep CJ5's utility and truck-like character, while wide whitewall creates a more stylized period appearance. Both are vintage-style choices, but they communicate very different restoration priorities.

Choosing the correct sidewall style depends on what kind of Jeep CJ5 you are restoring. A more work-focused or factory-leaning presentation usually benefits from blackwall tires, while a personalized or showroom-style build may support whitewalls if they match the vehicle's trim and era personality. Review period photos of similar Jeeps and judge the tire as part of the entire vehicle, not as an isolated component.

A properly selected and properly mounted tire from the listed Jeep CJ5 sizes can be suitable for public-road use when the entire vehicle is in sound mechanical condition. The available products shown here are bias-ply tires, so they should be approached as period-style equipment with handling characteristics different from modern radials. Safety depends on tire condition, inflation, wheel integrity, steering, brakes, and suspension working together.

For a collector Jeep CJ5, road use should begin with a careful inspection and a realistic understanding of how a short-wheelbase bias-ply 4x4 behaves. Expect slower steering response, more road feel, and more sensitivity to grooves or crosswinds than with a modern tire. A thoughtful setup and conservative driving style matter just as much as selecting the correct size.

Before driving a Jeep CJ5, check tire inflation, sidewall condition, tread integrity, wheel fasteners, steering play, brake operation, and any signs of tube leakage if tube-type tires are fitted. On the listed Jeep CJ5 sizes, all of the period fitments shown are bias-ply types, so condition and pressure are especially important. A vehicle that has been sitting can look fine at a glance while still hiding age-related problems.

A brief walk-around before each drive catches many issues early. Look for weather checking, bulges, uneven stance, or a tire that has gone soft since the last outing, then pay attention to steering behavior in the first mile. If the Jeep CJ5 wanders, vibrates, or pulls unusually, stop and inspect it rather than assuming the tire will settle in after a few miles.

A Jeep CJ5 running original-style bias-ply tires should be driven at moderate, sensible speeds that suit both the tire construction and the vehicle's overall condition. These period-style tires are not meant to make an early-1970s Jeep behave like a modern SUV on modern highways. Steering geometry, braking, suspension wear, and the short wheelbase all influence what feels safe and stable.

In practical terms, the right speed for a Jeep CJ5 is the speed at which the vehicle remains composed, predictable, and well within the driver's control. Freshly restored vehicles should be tested gradually on local roads before taking on longer or faster trips. If the Jeep shows wandering, hop, vibration, or heat buildup, reduce speed and address the cause rather than trying to drive through it.
