1988 Jeep Trucks Tire Fitment Guide

1988 Jeep Trucks vehicles use six sizes across the full range: 195/75R15, 205/75R15, 215/75R15, 225/75R15, 235/75R15, and 950-16.5. The Comanche uses 195/75R15, 205/75R15, and 225/75R15; Cherokee uses 205/75R15, 215/75R15, and 225/75R15; Wrangler uses 205/75R15, 215/75R15, and 225/75R15; Wagoneer uses 205/75R15; Grand Wagoneer uses 235/75R15; J10 uses 225/75R15 and 235/75R15; and J20 uses 950-16.5. The radial sizes mount on 15-inch wheels, while the J20 bias-ply size mounts on a 16.5-inch wheel.

That means year and make alone are not enough for a confident tire choice on 1988 Jeep Trucks. Start by identifying the exact model, then confirm whether it uses one of the 15-inch metric radials or the J20's separate 16.5-inch heavy-duty setup. If your model has more than one possible size, the next step is checking the vehicle's existing tire placard, wheel, or restoration history before settling on a replacement.

On a 1988 Jeep Trucks tire, 205/75R15 is a metric radial size. The 205 is the nominal section width in millimeters, 75 is the aspect ratio, the R means radial construction, and 15 is the wheel diameter in inches. On 1988 Jeep Trucks models, that size appears on Cherokee, Comanche, Wagoneer, and Wrangler applications.

For a buyer, that code tells you both the tire's general proportions and the wheel diameter it must mount on. It also helps separate this common 15-inch fitment from the wider 225 and 235 sizes and from the completely different 950-16.5 J20 fitment. If your Jeep currently wears 205/75R15 tires, confirm the wheel width falls within the range used by the tire you are considering before making a final choice.

On a 1988 Jeep Trucks tire, 950-16.5 is a numeric bias-ply truck size rather than a modern metric radial size. The 9.50 figure refers to nominal section width, and the 16.5 indicates the wheel diameter in inches. Within the 1988 Jeep Trucks range, this size is used on the J20 and stands apart from the 15-inch radial sizes found on the other models.

That distinction matters because a 16.5-inch tire is not interchangeable with a 15-inch wheel, and a bias-ply truck tire drives and feels differently from a passenger-style radial. J20 owners should treat 950-16.5 as its own fitment path and verify the wheel itself before ordering. If your truck has been altered over the years, inspect the mounted wheel diameter carefully rather than assuming it still carries its original setup.

You should choose the size that belongs to your exact 1988 Jeep Trucks model and wheel, not simply the one that looks closest. The 235/75R15 is a 15-inch radial used on Grand Wagoneer and some J10 applications, while the 950-16.5 is a 16.5-inch bias-ply truck tire used on the J20. Those sizes differ in both construction and wheel diameter, so they are not interchangeable choices for the same wheel.

In practice, this is less a style decision than a fitment decision. A J20 owner staying with original-type 16.5-inch wheels should remain in the 950-16.5 category, while Grand Wagoneer and J10 owners using 15-inch wheels should stay within their correct radial sizes. Confirming the wheel diameter first prevents the most common ordering mistake on full-size 1988 Jeep Trucks.

1988 Jeep Trucks tires span a broad mix of sidewall styles depending on size. The 15-inch radial sizes include narrow whitewall, wide whitewall, goldline, RBL, and RWL offerings, while the 950-16.5 J20 size comes in blackwall only. Whitewall options appear most often in the 195/75R15, 205/75R15, 225/75R15, and 235/75R15 sizes, and the all-terrain radial choices bring the more utilitarian raised-letter look.

That variety lets owners match the tire to the personality of the vehicle. A Grand Wagoneer or Wagoneer often looks at home with a whitewall treatment, while a Wrangler, Cherokee, or working-style pickup may suit a plainer or more truck-oriented sidewall. The best approach is to decide first whether you want an upscale, original-flavored appearance or a more functional utility look, then narrow to the sidewall style within the correct size.

1988 Jeep Trucks tires are available from BFGoodrich, Tornel, American Classic, Coker Classic, Maxxis, and STA. The 205/75R15 comes from BFGoodrich, Tornel, and American Classic; 215/75R15 comes from BFGoodrich, Coker Classic, and Tornel; 225/75R15 comes from BFGoodrich, Coker Classic, and American Classic; 195/75R15 comes from Coker Classic and American Classic; 235/75R15 comes from BFGoodrich, American Classic, Maxxis, and Coker Classic; and 950-16.5 comes from STA.

Brand choice on 1988 Jeep Trucks usually comes down to the size you need and the appearance you want. Some sizes lean heavily toward classic whitewall presentation, while others include more truck-style sidewalls such as RBL or RWL. Once the model and size are confirmed, compare the brands available in that size by sidewall treatment, load rating, and intended character rather than trying to force one brand across the entire Jeep range.

Rim width varies by size on 1988 Jeep Trucks tires. The 205/75R15 commonly fits 5.50 to 7.50-inch rims, 215/75R15 fits roughly 5.5 to 7.5-inch rims, 225/75R15 fits about 6.00 to 8.00-inch rims, 195/75R15 fits about 5.00 to 7.00-inch rims, 235/75R15 fits about 6.00 to 8.50-inch rims depending on the tire, and 950-16.5 fits 6.50 to 6.75-inch rims. All of those widths are tied to the individual tire size and product family, not to 1988 Jeep Trucks as a single blanket measurement.

Rim width matters because it affects how the tire sits on the wheel and can influence both appearance and road manners. If your Jeep has replacement wheels, that check becomes especially important before committing to a tire. Measure the wheel or verify its stamping first, then compare it to the approved width range for the size you plan to run.

The 15-inch radial sizes used on 1988 Jeep Trucks are generally presented as tubeless-style metric radials, while the 950-16.5 J20 truck tires are bias-ply products and should be matched to the specific tire and wheel combination being used. None of these sizes should be assumed to need the same tube setup simply because they belong to the same year and make. Tube practice depends on the tire construction, the wheel design, and the exact product sidewall marking.

For buyers, the safest approach is to treat tube use as a size-and-product-specific question rather than a Jeep-wide rule. Radial 15-inch applications often differ from older heavy-duty truck fitments in how they are set up. Before installation, verify the tire marking and inspect the wheel condition so the final assembly matches the product's intended use.

Original 1988 Jeep Trucks wheels can only be reused when the wheel diameter matches the tire size being selected. The 195/75R15, 205/75R15, 215/75R15, 225/75R15, and 235/75R15 sizes all mount on 15-inch wheels, while the J20's 950-16.5 requires a 16.5-inch wheel. That means the 15-inch sizes share a common wheel diameter category, but the 16.5-inch J20 fitment does not cross over.

Even within the 15-inch group, wheel diameter alone is not the only concern. Wheel width should still be checked against the tire you plan to use, especially if the vehicle has changed hands, been restored, or received aftermarket wheels at some point. A quick wheel verification before purchase can prevent a mismatch between the tire size you want and the wheel already on the Jeep.

A stored 1988 Jeep Trucks should be kept in a cool, dry, dark environment away from direct sunlight, standing moisture, and electric motors or other ozone-producing equipment. Tires stay healthier when they are clean, properly inflated, and not left pressed into one position for long periods. If the Jeep will sit for an extended time, rolling it occasionally or taking some load off the tires can help reduce flat-spotting and sidewall stress.

Storage habits matter just as much on an occasionally driven Jeep as they do on a show car. Radial 15-inch tires generally tolerate sitting better than older bias-ply designs, but even modern reproductions age faster when exposed to heat and ozone. If your 1988 Jeep Trucks includes a J20 with bias-ply truck tires, extra attention to long static storage is worthwhile.

Tires on a 1988 Jeep Trucks should be judged more by age and condition than by miles traveled. A good rule is to begin close inspection once tires reach the five- to seven-year range and to consider replacement as they approach ten years, even if tread depth still looks respectable. The DOT date code on the sidewall is the best starting point for establishing age.

Collector and hobby vehicles often accumulate very little mileage, which can make old tires look healthier than they really are. Rubber hardens over time, and internal aging does not always show up as obvious tread wear. If your Jeep is used for longer drives, trail use, or family cruising, age-based replacement is a smarter guide than waiting for the tread to wear out.

Tires on a 1988 Jeep Trucks should be inspected before every drive and more carefully before any extended outing. Look for cracking, cuts, bulges, irregular wear, and any sign that the tire is losing pressure. On tube-type or older heavy-duty style assemblies, the valve stem and overall wheel condition also deserve attention during every inspection.

Frequent checks are especially important on vintage-use vehicles that may sit for long stretches between drives. Problems often appear first at the sidewall, bead area, or around a valve stem rather than in the tread itself. A few minutes in the garage before heading out can catch age-related issues early and help avoid roadside trouble.

A 1988 Jeep Trucks Cherokee would have been a radial-tire vehicle from new, and the Cherokee applications in this range use 205/75R15, 215/75R15, or 225/75R15 depending on configuration. That places the Cherokee firmly in the late-1980s radial era rather than the earlier bias-ply period. Sidewall treatment could still vary by market presentation and owner preference, so the exact appearance should be checked against factory literature or marque-specific references.

For restoration work, the key question is usually not bias-ply versus radial, but which of the correct 15-inch metric sizes belongs on your specific Cherokee. Once that is settled, sidewall style becomes the next authenticity choice. If you are preparing for marque judging or a highly original restoration, factory brochures, surviving examples, and Jeep specialist communities are the best way to confirm the most era-appropriate presentation.

Correct tire fitment does matter when showing a 1988 Jeep Trucks, especially on preserved or restored examples where judges and knowledgeable enthusiasts notice stance, sidewall style, and overall period appearance. Size accuracy is the first step, followed by correct construction for the model and era, then a sidewall treatment that suits the way the vehicle would have appeared when new. A J20 wearing an incorrect wheel diameter or a luxury-oriented Grand Wagoneer wearing an obviously mismatched sidewall style can stand out quickly.

That does not mean every Jeep must wear the exact same visual treatment to be enjoyed, but authenticity-minded owners should think beyond simple fit. The most credible show presentation usually comes from matching the tire's size, construction category, and sidewall look to the vehicle's role in the lineup. Event-specific judging standards can differ, so checking with Jeep clubs or the event's own rules is worthwhile before final preparation.

For the 1988 Jeep Trucks J20, both STA Traxion and STA Super Transport are 950-16.5 bias-ply blackwall truck tires with the same 2,780-pound maximum load rating at 60 psi and the same 6.50 to 6.75-inch rim width range. The basic fitment category is the same, but the two lines are distinct series within STA's heavy-duty truck offerings. Their published weights are close as well, with Traxion at 40 pounds and Super Transport at 41 pounds.

That means the decision between them is not about changing wheel size or altering the J20's basic fitment. It is more about choosing between two period-appropriate heavy-duty truck tire lines within the same size and load class. J20 owners restoring a work-oriented truck often compare tread character and visual preference once the size, wheel diameter, and load requirements are already settled.

1988 Jeep Trucks tires can be suitable for highway driving when the correct size, load capacity, and condition are matched to the vehicle. Among the sizes that show a speed rating in the size marking, the 215/75R15 BFGoodrich All-Terrain T/A KO2 and 235/75R15 BFGoodrich All-Terrain T/A KO2 carry an S rating, which corresponds to 112 mph. Many of the classic-style whitewall radials do not display a speed letter in the visible size marking here, so the exact product should be checked individually before assuming a rating.

In real-world use, most 1988 Jeep Trucks will reach their mechanical comfort limit well before an S-rated tire's ceiling becomes relevant. Suspension design, braking capability, steering condition, and the Jeep's age usually matter more than top-speed potential during normal highway travel. The important step is matching the tire to the intended driving use and making sure the rest of the vehicle is equally road-ready.

Inflation pressure on 1988 Jeep Trucks tires depends on the exact size and product. Examples include 205/75R15 tires rated at 1,598 pounds at 35 psi, 215/75R15 options ranging from 1,742 pounds at 35 psi to 1,874 pounds at 32 psi, 225/75R15 options from 1,874 pounds at 35 psi to 2,094 pounds at 32 psi, 235/75R15 options from 1,985 pounds at 50 psi to 2,271 pounds at 32 psi, and 950-16.5 at 2,780 pounds at 60 psi. Those figures are tire ratings, not universal vehicle setting recommendations.

For actual use, start with the factory vehicle guidance when available, then compare it to the tire maker's rated pressure range for the exact tire on the Jeep. Pressure should never be transferred casually from one size to another just because both fit a 1988 Jeep Trucks model. The right number depends on vehicle configuration, tire size, and load, so keeping those distinctions straight is important.

Before a longer drive in a 1988 Jeep Trucks, inspect each tire for sidewall cracking, punctures, bulges, uneven wear, and proper inflation. Check the spare as closely as the four road tires, since old collector spares are often forgotten until they are needed. If the Jeep uses a heavy-duty or older-style assembly, give extra attention to valve stems and wheel condition as well.

Tires are only one part of a smart pre-trip routine on an older Jeep. Brakes, steering, cooling, lights, belts, and fluid levels all deserve a quick review before a highway outing or trail trip. A sound tire inspection combined with an overall mechanical check helps turn an old-vehicle drive into a pleasant one instead of a roadside repair session.
