The 1986 Isuzu Trucks Trooper came from the early generation of compact sport-utility vehicles that balanced everyday utility with genuine off-road character. Its upright body, simple mechanical layout, and durable reputation make it especially appealing to owners who still drive and preserve these trucks today. For this exact model year, the primary tire fitment is a 225/75R15 radial on a 15-inch rim, which keeps the fitment decision straightforward across the covered Trooper sub-models. The real choice is in presentation and product style, with whitewall variations, several radial series, and multiple brand options available. That makes it important to match the tire not just to size, but also to the truck's intended look and use.
Which Tire Size Is Right for The 1986 Isuzu Trucks Trooper
The 1986 Isuzu Trucks Trooper uses one primary tire size: 225/75R15, and it is a radial fitment for a 15-inch rim. That consistency across the covered sub-models means the main decision is not which size fits, but which tire style, whitewall treatment, and product specification best suits the truck's appearance and road use.
A 225/75R15 tire uses a modern metric radial format: 225 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 1986 Isuzu Trucks Trooper, this is the primary fitment and it suits owners who want a straightforward road-going radial in the proper size category. Available choices include BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar, with narrow and wide whitewall treatments across several tire series. That gives the buyer room to choose a more traditional appearance or a simpler driver-oriented presentation while staying in the correct size family.
Tire fitment is simple across the covered 1986 Isuzu Trucks Trooper sub-models because each one uses the same primary size. Checking the exact sub-model still helps confirm that the truck remains on its expected wheel setup before comparing whitewall style, brand, or other product differences.

1986 Isuzu Trucks Trooper DLX
The 1986 Isuzu Trucks Trooper DLX uses the same 225/75R15 radial fitment as the other covered Trooper versions. That keeps sizing straightforward and shifts the decision toward wheel compatibility, sidewall appearance, and whether the truck is being kept in a more restoration-oriented style or driven regularly.
The 1986 Isuzu Trucks Trooper LS also uses 225/75R15 radial tires, so there is no alternate primary size to sort through here. Tire selection becomes more about comparing whitewall treatments, radial series, and the actual wheel setup currently on the truck.
The 1986 Isuzu Trucks Trooper LX shares the 225/75R15 radial fitment used across the covered sub-model range. That allows the buyer to focus on choosing the right look and product details while confirming that the wheel width and overall vehicle setup remain compatible with the selected tire.
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 1986 Isuzu Trucks Trooper?
The 1986 Isuzu Trucks Trooper uses a 225/75R15 tire size. This is a radial fitment on a 15-inch rim, and it applies across the covered DLX, LS, and LX sub-models, so there is one primary size to work from when replacing tires on this vehicle.
That simplifies the first step, but size alone is not the only consideration. It is still smart to confirm that the truck has its expected wheel setup, especially if it has been modified over the years. After that, the real decision becomes choosing among the available 225/75R15 tires by whitewall style, brand, rim-width compatibility, and general intended use.
What size rim does a 1986 Isuzu Trucks Trooper use?
The primary tire fitment for the 1986 Isuzu Trucks Trooper uses a 15-inch rim diameter. That matches the 225/75R15 size code, where the final 15 identifies the wheel diameter the tire is built to mount on.
Rim diameter should match exactly, but diameter is only part of the fitment picture. Wheel width also matters, and the available 225/75R15 products do not all share the same rim-width specification. Before choosing a tire, confirm the actual wheel width on the truck and make sure the selected tire falls within the wheel's compatible range.
Do all 1986 Isuzu Trucks Trooper sub-models use the same tire size?
Yes. The covered 1986 Isuzu Trucks Trooper DLX, LS, and LX sub-models all use the same primary tire size: 225/75R15. Each of those fitments is radial, so there is no split between sub-models for a different primary size or construction.
That consistency makes replacement easier, but it does not remove the need to inspect the truck itself. Older sport-utility vehicles are often changed with aftermarket wheels, suspension work, or previous tire substitutions. Once the current wheel setup is confirmed, the choice shifts to appearance and specifications such as whitewall width, rim-width range, and load capacity.
Choosing the Right Tire
What should I consider when choosing a 225/75R15 tire for a 1986 Isuzu Trucks Trooper?
Start with the core fitment: the 1986 Isuzu Trucks Trooper uses a 225/75R15 radial tire on a 15-inch rim. From there, compare the tire's rim-width specification, load rating, and overall style so the selection matches both the wheel and the way the truck will actually be used.
Appearance plays a big role here because the available tires include different whitewall treatments and several brand or series options. A narrow whitewall gives a different presentation than a wide whitewall, and some owners may prefer a cleaner driver look while others want a more restoration-minded style. Matching the tire to the truck's purpose usually leads to the best choice.
What sidewall styles are available for 1986 Isuzu Trucks Trooper tires?
The available 225/75R15 tires for a 1986 Isuzu Trucks Trooper include both narrow whitewall and wide whitewall styles. That gives owners a useful appearance choice even while staying within the same primary size and radial construction.
Sidewall style changes the truck's visual character more than many buyers expect. A wide whitewall can create a stronger vintage presentation, while a narrower whitewall often feels more understated. Since all of these choices remain in the same size family, the main task is deciding which look suits the vehicle best and then confirming the selected tire's wheel compatibility.
What brands offer tires for the 1986 Isuzu Trucks Trooper?
225/75R15 tires for the 1986 Isuzu Trucks Trooper are available from BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar. The product range also includes multiple tire series, so brand is only one part of the comparison.
Choosing among them should come down to the specific tire's details rather than brand name alone. Compare sidewall treatment, rim-width specification, load figure, and the general style of the tire. That approach is especially useful on an older Trooper, where appearance and wheel compatibility may matter just as much as simply finding the correct size.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Isuzu Trucks Trooper?
A period-style 1986 Isuzu Trucks Trooper should start with the correct primary size, which is 225/75R15 in radial construction. From there, the most important visual decision is usually sidewall treatment, since both narrow whitewall and wide whitewall options are available in this size.
The right choice depends on how the truck is being presented. Some owners want a cleaner driver-style look, while others want a more restoration-oriented appearance that stands out more. If exact originality matters, compare the tire's general look against period photos, marque knowledge, or other vehicle-specific references rather than assuming any current sidewall treatment is automatically exact.
Does correct tire fitment matter for a 1986 Isuzu Trucks Trooper restoration?
Yes, correct tire fitment matters because the tire has a major effect on stance, wheel appearance, and the overall character of a restored 1986 Isuzu Trucks Trooper. Staying with the proper 225/75R15 size keeps the restoration grounded in the vehicle's intended fitment range.
Construction is straightforward here because the primary fitment is already radial, so the visual decision usually centers on sidewall style and brand presentation. Even on a restoration, the actual wheel dimensions should still be checked before mounting new tires. Older trucks sometimes carry replacement wheels that change what will properly seat and clear.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Isuzu Trucks Trooper?
Yes. Even though the primary size for a 1986 Isuzu Trucks Trooper is 225/75R15, modifications can change what works on the truck in practice. Aftermarket wheels, altered wheel width, suspension changes, or body modifications can all affect how a tire mounts and how much clearance it has.
That is why the current vehicle setup matters just as much as the original size callout. Check the actual wheel diameter and width first, then look for enough clearance at the fenders, steering components, and suspension through the full range of motion. A correct-size tire still needs to be compatible with the truck as it sits today.
What should I inspect before driving a 1986 Isuzu Trucks Trooper on new tires?
Before driving a 1986 Isuzu Trucks Trooper on new tires, inspect the wheels, valve stems, lug hardware, and general wheel condition, then confirm that the tires are mounted in the correct 225/75R15 size. It is also smart to check for proper inflation, visible bead seating, and any immediate signs of interference.
The rest of the truck deserves attention too, especially on an older utility vehicle that may have seen long storage or uneven use. Look over steering and suspension components, verify clearance while turning, and recheck air pressure after the first drives. Catching a rubbing issue or wheel mismatch early helps protect both the tires and the vehicle.
How should 225/75R15 tires on a collector 1986 Isuzu Trucks Trooper be maintained?
Collector-use 225/75R15 tires on a 1986 Isuzu Trucks Trooper should be kept properly inflated, inspected regularly, and protected from long periods of harsh storage conditions. Pay attention to tread wear, sidewall cracking, bulges, cuts, and recurring air loss, even if the truck is driven only occasionally.
Low annual mileage can hide tire aging, so condition matters as much as tread depth on a vintage SUV. Clean, dry storage away from prolonged sunlight, excess heat, and ozone-producing equipment helps preserve the tires. A quick inspection before each outing and a more careful check before longer drives can prevent avoidable problems on the road.
