The 2002 GMC Trucks Jimmy arrived near the end of the compact SUV era that blended everyday drivability with genuine truck-based utility. Buyers still look to these Jimmys for practical road use, light trail duty, and period-correct sport-utility character, especially in LS and ZR2 form. Tire fitment on the 2002 GMC Trucks Jimmy stays within 15-inch radial sizes, but the exact size changes by sub-model, from 235/70R15 and 235/75R15 up to 31X10.50R15 on the ZR2 w/Off-Road. That creates meaningful choice in profile, stance, and available sidewall treatments. The right selection starts with the exact trim and then balances appearance, wheel compatibility, and intended use.
Which Tire Size Is Right for The 2002 GMC Trucks Jimmy
Three primary tire sizes apply to the 2002 GMC Trucks Jimmy, and the correct one depends on the specific sub-model. All three are radial tires for 15-inch wheels, but they differ in profile and overall proportions. The first step is confirming whether the vehicle is an LS, LS w/Off-Road, ZR2, or ZR2 w/Off-Road, because that determines which size belongs on the vehicle before comparing brands, sidewall styles, or tire series.
A 235/70R15 tire uses a 235-millimeter section width, a 70-series aspect ratio, radial construction, and a 15-inch rim diameter. On the 2002 GMC Trucks Jimmy, this size is the road-oriented fitment used on the LS, giving the buyer a modern metric radial format that is easy to interpret and compare. Available choices include blackwall, wide whitewall, narrow whitewall, redline, and raised white letter styles from brands such as Cooper, Avon, BFGoodrich, and Michelin. This size is the one to evaluate when the goal is preserving standard LS fitment while still choosing among appearance and series differences.
A 235/75R15 tire keeps the same 235-millimeter nominal width as 235/70R15 but uses a taller 75-series profile on a 15-inch radial casing. On the 2002 GMC Trucks Jimmy, this size applies to the LS w/Off-Road and ZR2, making it an important fitment for buyers whose vehicle sits between standard-road and more utility-focused configurations. Product choices span all-terrain raised white letter options as well as several whitewall treatments from American Classic, BFGoodrich, Coker Classic, Maxxis, Tornel, and Travelstar. This size deserves close attention when sub-model identification is correct but appearance and intended use still vary widely.
The 31X10.50R15 format is a flotation-style light truck radial that states the tire's approximate overall diameter first, then section width, followed by its 15-inch rim diameter. On the 2002 GMC Trucks Jimmy, this larger radial size is associated with the ZR2 w/Off-Road configuration, where tire height and width become a bigger part of the vehicle's stance and clearance picture. The available option uses a raised white letter sidewall in BFGoodrich's All-Terrain T/A KO2 series. This is the size to confirm carefully when the Jimmy has the off-road-oriented ZR2 setup and the wheel package needs to match that larger tire format.
Tire fitment changes across the 2002 GMC Trucks Jimmy lineup, so confirming the exact sub-model is the key first step. The four covered configurations all use 15-inch radial tires, but the actual size shifts from standard metric fitments to a larger flotation-style off-road size.

2002 GMC Trucks Jimmy LS
The 2002 GMC Trucks Jimmy LS uses the 235/70R15 radial size, which is the most road-oriented fitment in this group. That makes tire choice less about identifying alternate primary sizes and more about selecting the right series, brand, and sidewall presentation within the correct LS fitment.
The 2002 GMC Trucks Jimmy LS w/Off-Road moves to a 235/75R15 radial, giving it a different profile than the standard LS. Tire selection here should start with that taller metric size and then narrow down the choice by intended use, sidewall style, and wheel compatibility.
The 2002 GMC Trucks Jimmy ZR2 also uses the 235/75R15 radial size. That means the key decision is not between multiple primary sizes for this sub-model, but between the available tire types and appearances that suit a ZR2 being driven, refreshed, or restored.
The 2002 GMC Trucks Jimmy ZR2 w/Off-Road uses the larger 31X10.50R15 radial size. Because this flotation-style fitment changes the vehicle's tire footprint and overall presentation, wheel setup and clearance deserve extra attention before choosing a replacement.
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 2002 GMC Trucks Jimmy Tires for Sale
Available 2002 GMC Trucks Jimmy tires cover a broad range of radial choices, from Cooper, Avon, BFGoodrich, and Michelin in 235/70R15 to several whitewall and all-terrain options in 235/75R15, plus a BFGoodrich All-Terrain T/A KO2 offering in 31X10.50R15.
Common 2002 GMC Trucks Jimmy tire questions usually come down to sub-model-specific sizing, 15-inch wheel fitment, sidewall and series choices, and what to inspect before putting a collector-era SUV back into regular road use.
Tire Size & Fitment
What tire size fits a 2002 GMC Trucks Jimmy?
The 2002 GMC Trucks Jimmy uses one of three radial tire sizes, depending on the sub-model: 235/70R15, 235/75R15, or 31X10.50R15. The LS uses 235/70R15, the LS w/Off-Road uses 235/75R15, the ZR2 uses 235/75R15, and the ZR2 w/Off-Road uses 31X10.50R15.
The practical issue is that not every Jimmy used the same size, even though all of them used 15-inch wheels. Matching the exact trim matters before comparing tire styles or brands, and it is wise to confirm the actual wheel and tire setup on the vehicle if it has ever been modified or updated from its original sub-model configuration.
What size rim does a 2002 GMC Trucks Jimmy use?
The covered tire fitments for the 2002 GMC Trucks Jimmy all use a 15-inch rim diameter. That applies whether the vehicle takes 235/70R15, 235/75R15, or 31X10.50R15, so the wheel diameter remains consistent even though the tire size changes across sub-models.
Rim diameter is only one part of the fitment picture. Wheel width can still vary by tire choice, especially when comparing a standard metric size to the larger 31X10.50R15 flotation-style size, so the actual wheel should be checked before purchase rather than assuming any 15-inch rim will suit every Jimmy tire option.
Why does the 2002 GMC Trucks Jimmy have more than one tire size?
The 2002 GMC Trucks Jimmy has more than one tire size because fitment changes with the sub-model. The LS uses 235/70R15, both the LS w/Off-Road and ZR2 use 235/75R15, and the ZR2 w/Off-Road steps up to 31X10.50R15 for a more off-road-oriented setup.
That difference affects more than the numbers on the sidewall. Profile, overall tire proportions, and the kind of products available can all change with the sub-model, so identifying the vehicle correctly is the first step before choosing between raised white letter, whitewall, touring-style, or all-terrain radial options.
Choosing the Right Tire
What should I consider when choosing a 2002 GMC Trucks Jimmy tire?
Start with the exact sub-model, because the 2002 GMC Trucks Jimmy does not share one universal tire size. After confirming the correct size, the next selection factors are radial tire series, sidewall treatment, wheel-width suitability, and whether the vehicle is being kept in a road-oriented, restoration-minded, or more utility-focused configuration.
A 235/70R15 LS can be approached differently than a ZR2 w/Off-Road on 31X10.50R15. Some buyers want a traditional whitewall or redline presentation, while others need raised white letter or all-terrain character, so the best approach is to match the tire's look and specifications to how the Jimmy is actually driven and presented.
What sidewall styles are available for 2002 GMC Trucks Jimmy tires?
Sidewall choices for the 2002 GMC Trucks Jimmy include blackwall, narrow whitewall, wide whitewall, redline, and raised white letter styles, depending on the tire size. The broadest appearance variety appears in the 235/70R15 and 235/75R15 sizes, while 31X10.50R15 is offered in a raised white letter all-terrain format.
That variety makes sidewall style an important part of the buying decision, especially on a late classic SUV where the tire can change the whole visual impression. A whitewall or redline leans toward a more restoration-oriented or custom look, while blackwall and raised white letter options usually suit a more utilitarian or sport-truck presentation.
What brands offer tires for the 2002 GMC Trucks Jimmy?
Available tire brands for the 2002 GMC Trucks Jimmy include Cooper, Avon, BFGoodrich, Michelin, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Brand availability depends on the size, with the widest range appearing in 235/70R15 and 235/75R15, while 31X10.50R15 is represented by BFGoodrich.
Brand choice should be evaluated alongside the tire series and sidewall style rather than by name alone. Some options are oriented toward traditional appearance, some toward touring-style radial presentation, and some toward all-terrain use, so the better comparison is how each brand's offering aligns with the Jimmy's actual size, wheel, and purpose.
Restoration & Appearance
Which tire should I choose for a period-style 2002 GMC Trucks Jimmy?
A period-style 2002 GMC Trucks Jimmy tire starts with the correct sub-model size, then narrows to the appearance that suits the vehicle's presentation. In 235/70R15 and 235/75R15, choices include blackwall, whitewall, redline, and raised white letter radials, while the ZR2 w/Off-Road size centers on a more truck-oriented raised white letter look.
The right answer depends on whether the Jimmy is being kept close to its original visual era, customized, or prepared for regular road use with a traditional look. For buyers chasing exact restoration authenticity, vehicle-specific literature, surviving examples, and marque expertise are worth checking before settling on a stripe or whitewall treatment.
How does tire construction affect the appearance of a restored 2002 GMC Trucks Jimmy?
For the 2002 GMC Trucks Jimmy, the primary fitments are radial tires, so the appearance differences come less from bias-ply versus radial construction and more from the tire's profile, sidewall style, and series character. A blackwall touring radial presents differently than a wide whitewall, redline, or raised white letter tire in the same basic size family.
That means restoration appearance is shaped by details the eye catches immediately, especially sidewall treatment and overall stance. Even within the correct size, a Jimmy can look more stock, more custom, or more off-road-focused depending on the tire chosen, so it helps to decide whether the vehicle's finish should feel understated, sporty, or truck-oriented.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 GMC Trucks Jimmy?
Yes, modifications can affect tire fitment on a 2002 GMC Trucks Jimmy even when the nominal size appears correct. Aftermarket wheels, suspension changes, ride-height alterations, or previous trim-package substitutions can change the wheel width, backspacing, and available clearance around the fenders, steering components, and suspension.
That matters most when moving between the Jimmy's different sub-model size ranges, especially from a standard metric size to 31X10.50R15. A vehicle that has been lowered, lifted, or fitted with non-original wheels should be measured directly so the chosen tire matches the actual setup rather than only the original sub-model designation.
What should I inspect before driving a 2002 GMC Trucks Jimmy on new tires?
Before driving a 2002 GMC Trucks Jimmy on new tires, inspect the wheels for damage, confirm the rim diameter and width are appropriate for the chosen size, and make sure the steering and suspension have adequate clearance. It also helps to check alignment condition, valve stems, lug hardware, and inflation before putting the vehicle into regular service.
A newly mounted tire cannot correct problems elsewhere in the chassis. Worn shocks, sagging springs, loose steering parts, or brake issues can change how the Jimmy behaves on the road, so a full walk-around and underbody check is sensible, especially on an older SUV that may have seen long storage or intermittent use.
How should tires on a collector-era 2002 GMC Trucks Jimmy be maintained?
Tires on a collector-era 2002 GMC Trucks Jimmy should be kept properly inflated, inspected regularly for cracking, bulges, cuts, uneven wear, and slow air loss, and protected from long exposure to sunlight, moisture, and ozone sources. A Jimmy that is driven only occasionally still needs routine checks because age and storage conditions affect tires as much as mileage does.
Regular movement and pressure checks help prevent problems from developing unnoticed between drives. It is also smart to look over tread condition before any longer trip and to recheck clearance if the vehicle has had wheel changes, suspension work, or seasonal storage, since older SUVs often accumulate small fitment changes over time.
