The 1988 Isuzu Trucks Trooper comes from the era when compact sport utility vehicles were gaining a reputation for real utility, upright styling, and go-anywhere character. Buyers still seek these Troopers for their simple, durable feel and their place in the rise of imported 4x4 wagons. For this exact model year and model, the primary tire size is 235/75R15 in radial construction on a 15-inch rim. That opens up a useful range of choices, from all-terrain raised white letter tires to narrow and wide whitewall radials in several classic-style series. The key is matching the tire to the way the Trooper is used, while confirming wheel dimensions and overall clearance on the vehicle as it sits today.
Which Tire Size Is Right for The 1988 Isuzu Trucks Trooper
The 1988 Isuzu Trucks Trooper uses one primary tire size: 235/75R15, a radial fitment for a 15-inch rim. That same size is used across the covered S, LS, and XS sub-models, so the main decision is not which primary size fits, but which version of that size best suits the vehicle's appearance, driving use, and wheel setup.
A 235/75R15 tire uses modern metric sizing: 235 is the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 15 is the rim diameter in inches. On the 1988 Isuzu Trucks Trooper, this is the standard radial-format fitment and it aligns well with the vehicle's late-1980s SUV character. Available choices include BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar, with sidewall treatments ranging from raised white letter to narrow and wide whitewalls. This size makes selection more about tread style, sidewall appearance, and wheel compatibility than about sorting through multiple primary fitments.
Tire fitment is straightforward across the covered 1988 Isuzu Trucks Trooper sub-models. The S, LS, and XS all use the same 235/75R15 radial size, so sub-model identification matters less than confirming the actual wheels and overall setup on the vehicle.

1988 Isuzu Trucks Trooper LS
The 1988 Isuzu Trucks Trooper LS uses the same 235/75R15 radial tire size as the other covered sub-models. That keeps tire selection focused on sidewall style, tread character, and rim-width compatibility rather than on finding a different primary fitment for the LS.
The 1988 Isuzu Trucks Trooper S also uses 235/75R15 radial tires on a 15-inch rim. For an S model, the practical choice comes down to whether the vehicle needs a more truck-oriented look, such as raised white letters, or a more restoration-minded whitewall presentation.
The 1988 Isuzu Trucks Trooper XS shares the same 235/75R15 radial fitment found on the other covered versions. That means an XS owner can compare available tire series and sidewall styles without needing to navigate a separate primary size.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1988 Isuzu Trucks Trooper?
The 1988 Isuzu Trucks Trooper uses 235/75R15 tires in radial construction. That size applies across the covered S, LS, and XS sub-models, making the primary fitment straightforward for this exact year and model.
The next step is confirming that the vehicle still has the correct 15-inch wheels and an appropriate wheel width for the tire being considered. Many older SUVs have seen wheel changes over the years, so checking the actual rim dimensions and making sure the tire clears the suspension and bodywork is still worthwhile before making a final selection.
What size rim does a 1988 Isuzu Trucks Trooper use?
The primary tire fitment for the 1988 Isuzu Trucks Trooper is built around a 15-inch rim diameter. The 235/75R15 size itself confirms that the tire is intended for a 15-inch wheel.
Rim diameter is only part of the fitment picture, especially on an older utility vehicle. Wheel width also matters, and the available 235/75R15 products cover a range of widths depending on the tire series. It helps to measure the wheels on the vehicle rather than assuming they are original, particularly if the Trooper has been modified or wears aftermarket wheels.
Do all 1988 Isuzu Trucks Trooper sub-models use the same tire size?
The covered 1988 Isuzu Trucks Trooper sub-models all share the same primary tire size: 235/75R15 radial. That includes the S, LS, and XS, so there is no split in primary fitment among those versions.
That consistency simplifies the search, but it does not remove the need to check the vehicle itself. An individual Trooper may have replacement wheels, suspension changes, or cosmetic preferences that affect which 235/75R15 tire makes the most sense. Once the size is confirmed, the real choice becomes tread style, sidewall appearance, and compatibility with the wheel width already on the truck.
Choosing the Right Tire
What should I consider when choosing a 235/75R15 tire for a 1988 Isuzu Trucks Trooper?
Start with the correct primary size, which is 235/75R15, and make sure the tire matches the way the Trooper will be used. Some options lean toward an all-terrain truck look, while others focus more on classic-style whitewall presentation.
Wheel width, load capacity, sidewall style, and the overall character of the tire series are all worth comparing. A raised white letter tire creates a different appearance than a narrow or wide whitewall, even within the same size. It also helps to consider whether the Trooper is a driver, a restoration-minded vehicle, or a more utility-focused SUV before settling on a final option.
What sidewall styles are available for 1988 Isuzu Trucks Trooper tires?
The 1988 Isuzu Trucks Trooper has several sidewall styles available in 235/75R15, including RWL, narrow whitewall, and wide whitewall. Those choices give the vehicle a noticeably different visual character without changing its primary tire size.
A raised white letter sidewall tends to suit a more truck-oriented or late-1980s sport utility look, while narrow and wide whitewalls create a more styled, restoration-oriented presentation. The best choice depends on how the Trooper is being finished and driven. Matching the sidewall treatment to the vehicle's intended look is often just as important as choosing the brand or tire series.
What brands offer tires for the 1988 Isuzu Trucks Trooper?
Available 235/75R15 tires for the 1988 Isuzu Trucks Trooper include offerings from BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Those brands cover both all-terrain and classic-style radial choices in the correct size.
Brand alone should not be the only deciding factor. It makes sense to compare the tire series, sidewall treatment, rim-width specification, and load figure at the stated pressure for the specific tire under consideration. That approach helps narrow the field based on how the Trooper will actually be used and what appearance the owner wants to preserve or create.
Restoration & Appearance
Which tire should I choose for a period-style 1988 Isuzu Trucks Trooper?
A period-style 1988 Isuzu Trucks Trooper usually starts with the correct 235/75R15 radial size and then narrows the choice by visual character. A raised white letter tire can reflect the sport-utility image of the era, while whitewall radials create a more customized or presentation-focused look.
The right choice depends on the specific direction of the vehicle rather than on one universally correct appearance. Owners seeking exact restoration detail should compare the tire against original photos, build literature, and marque-specific references. For most buyers, staying with the correct size and choosing a sidewall style that matches the Trooper's finish delivers the most convincing result.
How does tire construction affect the appearance of a restored 1988 Isuzu Trucks Trooper?
On the 1988 Isuzu Trucks Trooper, the primary fitment is already a radial, so construction choice is less about switching from an earlier bias-ply look and more about selecting the visual style within a radial tire. The appearance difference comes mainly from tread character and sidewall treatment.
That means a restoration-minded owner should pay close attention to whether the tire uses raised white letters, a narrow whitewall, or a wide whitewall. Each changes the personality of the vehicle even though the underlying 235/75R15 sizing remains the same. A tire can support a period-style presentation without making an unsupported claim of exact factory originality.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1988 Isuzu Trucks Trooper?
Yes. Even though the primary size for a 1988 Isuzu Trucks Trooper is 235/75R15, modifications can change whether a particular tire in that size is appropriate for the vehicle. Wheel width, wheel offset, suspension lift or lowering, and body changes can all affect fitment.
A Trooper that still uses stock-style wheels may accept the size exactly as expected, while one with aftermarket wheels may need closer inspection. It is smart to check clearance at full steering lock and through suspension movement, especially on an SUV that may see uneven surfaces. Verifying the actual wheel setup prevents surprises after the tires are mounted.
What should I inspect before driving a 1988 Isuzu Trucks Trooper on new tires?
Before putting a 1988 Isuzu Trucks Trooper back on the road with new tires, inspect the wheels for damage, confirm proper wheel hardware, and make sure the tires are inflated to a suitable pressure for the tire and vehicle setup. The suspension and steering should also be checked for obvious looseness or wear.
A road test is safer when the rest of the vehicle is ready to support the tires. Look for rubbing, listen for unusual noises, and recheck air pressure after the first few drives. On an older SUV, alignment condition and brake health matter just as much as the tires themselves, especially if the vehicle has spent long periods parked.
How should 235/75R15 tires on a collector 1988 Isuzu Trucks Trooper be maintained?
Collector-use 235/75R15 tires on a 1988 Isuzu Trucks Trooper should be kept properly inflated, inspected regularly, and protected from long periods of heat, direct sunlight, and moisture when the vehicle is stored. Sidewalls and tread should be watched for cracking, cuts, bulges, or uneven wear.
Low annual mileage does not eliminate the need for inspection, because age and storage conditions can matter as much as tread depth on a collector vehicle. Moving the Trooper periodically helps avoid prolonged flat spotting, and checking for slow air loss before each outing is a good habit. Any sign of damage or questionable condition deserves a closer look before highway use.
