The 2001 Isuzu Trucks Trooper comes from the last chapter of Isuzu’s body-on-frame SUV era, when durability, cargo space, and real off-pavement ability still mattered more than carlike styling. It remains a practical choice for owners who use their Trooper as a dependable trail, towing, or utility vehicle and for enthusiasts who appreciate its straightforward 4x4 character. This model uses a 245/70R16 radial tire, keeping the fitment question simple across the lineup. The main decision shifts to choosing the right tire style and specification within that size, including an all-terrain raised white letter option. Before changing anything, confirm the actual wheel setup and how the Trooper is used on road or off pavement.
Which Tire Size Is Right for The 2001 Isuzu Trucks Trooper
The 2001 Isuzu Trucks Trooper uses one primary tire size: 245/70R16. It is a radial tire on a 16-inch rim, and that same size carries across LS, Limited, and S sub-models. With size fitment staying consistent, the real choice becomes selecting the right tire within that size for your wheel width, intended driving use, and preferred appearance.
A 245/70R16 tire uses a modern metric sizing format: 245 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. On the 2001 Isuzu Trucks Trooper, this size suits the vehicle’s later-model SUV fitment and straightforward 16-inch wheel package. Available choices in this size include a BFGoodrich All Terrain T/A KO2 with raised white letter sidewalls. It is the size to use when the Trooper still has its correct 16-inch wheel setup and you want to compare tire character, rim-width compatibility, and use case rather than alternate fitments.
Tire fitment is straightforward across the covered 2001 Isuzu Trucks Trooper sub-models. LS, Limited, and S all use the same 245/70R16 radial size, so the key step is confirming that the vehicle still has its original 16-inch wheel diameter and has not been modified.

2001 Isuzu Trucks Trooper LS
The 2001 Isuzu Trucks Trooper LS uses the same 245/70R16 radial tire as the other covered sub-models. That keeps selection focused on tire type, sidewall presentation, and wheel-width compatibility rather than sorting through multiple factory size combinations.
The 2001 Isuzu Trucks Trooper Limited also uses 245/70R16 radial tires. For this sub-model, the decision is less about basic fitment and more about choosing a tire that matches the vehicle’s current wheel setup and the way it is driven.
The 2001 Isuzu Trucks Trooper S shares the 245/70R16 radial fitment used across the lineup. That makes it easier to compare available tires in one size while still checking wheel condition, width, and any suspension or wheel changes made over time.
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.
Best 2001 Isuzu Trucks Trooper Tires for Sale
Available 245/70R16 tires for the 2001 Isuzu Trucks Trooper focus on radial all-terrain fitment rather than multiple size choices. The current option uses BFGoodrich’s All Terrain T/A KO2 series with raised white letter sidewalls, giving buyers a clear comparison point for wheel-width range, load specification, and intended use.
Common 2001 Isuzu Trucks Trooper tire questions usually center on the 245/70R16 size, 16-inch rim fitment, product selection, modifications, and the checks worth making before putting an older SUV back into regular road use.
Tire Size & Fitment
What tire size fits a 2001 Isuzu Trucks Trooper?
The 2001 Isuzu Trucks Trooper uses a 245/70R16 tire size. This is the primary fitment across the covered Trooper sub-models, including LS, Limited, and S, and it is a radial construction on a 16-inch rim.
That consistency makes the first fitment check fairly simple, but it is still smart to confirm what is actually on the vehicle today. A Trooper with aftermarket wheels, previous tire changes, or suspension modifications may need extra clearance and wheel-width review before selecting a replacement in the same nominal size.
What size rim does a 2001 Isuzu Trucks Trooper use?
The 2001 Isuzu Trucks Trooper uses a 16-inch rim diameter with its 245/70R16 tire fitment. The tire size itself confirms that wheel diameter, since the final number in the size code refers to the rim diameter in inches.
Wheel diameter is only part of the picture, so it helps to confirm wheel width as well before buying tires. The available LT245/70R16/D option is built around a defined rim-width range, and a Trooper that has had replacement wheels installed should be checked carefully for proper wheel match and clearance.
Do all 2001 Isuzu Trucks Trooper sub-models use the same tire size?
Yes. The covered 2001 Isuzu Trucks Trooper LS, Limited, and S sub-models all use the same 245/70R16 radial tire size. There is no split here between trim levels that would force a different primary size choice.
That means sub-model identification is less important than confirming the vehicle’s present wheel and suspension setup. If the Trooper remains close to stock, tire selection is mainly about choosing the right tire type and specifications within 245/70R16 rather than sorting through several factory size combinations.
Choosing the Right Tire
What should I consider when choosing a 245/70R16 tire for a 2001 Isuzu Trucks Trooper?
Start with the correct size, which is 245/70R16, and confirm that the tire matches the Trooper’s 16-inch wheel setup. Construction is straightforward here because the fitment is radial, so the next comparison points are tire type, load specification, rim-width suitability, and how the vehicle is actually used.
A Trooper that sees trail use, gravel roads, or heavier utility duty may benefit from a more aggressive all-terrain design than one used mostly on pavement. It also helps to compare sidewall style, weight, and wheel-width compatibility so the tire suits both the vehicle’s setup and the owner’s expectations.
What sidewall styles are available for 2001 Isuzu Trucks Trooper tires?
The available 245/70R16 product for the 2001 Isuzu Trucks Trooper uses an RWL sidewall, meaning raised white letters. That gives the tire a more traditional light-truck and SUV appearance than a plain black sidewall.
Sidewall style does not change the basic fitment size, but it can change how the Trooper presents visually. Raised white letters tend to suit owners who want a more period-appropriate truck look, while buyers comparing future alternatives may want to consider whether appearance matters as much as tread style and load capability.
What brands offer tires for the 2001 Isuzu Trucks Trooper?
The available product in the primary 245/70R16 fitment for the 2001 Isuzu Trucks Trooper is from BFGoodrich. It appears in the All Terrain T/A KO2 series and uses a radial construction suited to the Trooper’s modern SUV tire format.
With a single brand currently represented in this fitment set, the comparison becomes more about whether that tire’s all-terrain character matches the way the vehicle is driven. Wheel-width compatibility, load needs, and visual preference still matter, especially on a Trooper that may serve both highway and off-pavement duties.
Restoration & Appearance
Which tire should I choose for a period-style 2001 Isuzu Trucks Trooper?
A period-style approach for a 2001 Isuzu Trucks Trooper starts with keeping the correct 245/70R16 radial size on a 16-inch wheel. Staying with the proper size preserves the SUV’s intended stance more effectively than chasing a dramatically taller, wider, or more modernized look.
Appearance then comes down to tire character rather than factory-claim assumptions. An all-terrain radial with raised white letters can suit the Trooper’s early-2000s truck-based personality, but owners pursuing exact historical presentation should still compare against original sales literature, surviving examples, or marque-specific references before finalizing a restoration-oriented setup.
Does correct tire fitment matter for a 2001 Isuzu Trucks Trooper restoration?
Yes, correct tire fitment matters because the 2001 Isuzu Trucks Trooper uses a specific 245/70R16 radial size tied to its 16-inch wheel package. Even on a later collector SUV, the right size has a strong effect on stance, wheelwell fill, and the overall visual balance of the vehicle.
Restoration-minded owners should pay attention to more than just the numbers on the sidewall. Tread style, sidewall presentation, and whether the vehicle still wears stock wheels all influence how authentic or era-appropriate the finished Trooper looks, especially when it is viewed next to unmodified examples.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2001 Isuzu Trucks Trooper?
Yes. A 2001 Isuzu Trucks Trooper may start with a 245/70R16 tire on a 16-inch rim, but aftermarket wheels, suspension lifts, lowering, alignment changes, or body modifications can all affect how that size sits and clears the vehicle.
The safest approach is to verify the actual wheel diameter and width already on the SUV, then check steering travel and clearance at full lock and under suspension movement. Even when the sidewall shows the correct nominal size, wheel offset and previous modifications can change the real fitment picture.
What should I inspect before driving a 2001 Isuzu Trucks Trooper on new tires?
Before road use, inspect wheel condition, lug hardware, valve stems, and tire pressure, then look over the suspension and steering for looseness that could affect how the new tires wear. It also helps to make sure the wheels are the correct 16-inch diameter for the Trooper’s 245/70R16 fitment.
A quick clearance check is worthwhile once the tires are mounted, especially if the Trooper has seen wheel or suspension changes over the years. After the first drives, recheck inflation and look for any uneven wear, rubbing marks, vibration, or air loss that could point to a setup issue.
How should 245/70R16 tires on a collector 2001 Isuzu Trucks Trooper be maintained?
245/70R16 tires on a collector-era 2001 Isuzu Trucks Trooper should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long periods of sun exposure or storage near ozone-producing equipment. Low annual mileage does not stop tires from aging.
Routine checks matter most on SUVs that spend more time parked than driven. A Trooper that sits for extended periods benefits from occasional movement, clean storage conditions, and close attention to air loss before each outing, since age and storage history can become just as important as remaining tread depth.
