The 1998 Toyota Trucks T100 sits in an interesting spot in Toyota truck history, bridging compact-truck durability with the added size and capability many buyers wanted in the late 1990s. It remains a practical choice for owners who use their trucks, preserve them, or want a period-appropriate look without losing everyday drivability. Tire fitment on the 1998 Toyota Trucks T100 stays firmly in modern radial territory, with 215/75R15, 235/75R15, and 265/70R16 sizes used depending on the specific configuration. That opens the door to different visual directions, from raised white letter all-terrain tires to narrow or wide whitewall radials. The key is matching the tire to the truck's exact sub-model, wheel diameter, and intended use.
Which Tire Size Is Right for The 1998 Toyota Trucks T100
Three tire sizes apply to the 1998 Toyota Trucks T100, and the right one depends on the truck's exact sub-model and wheel diameter. Two sizes use 15-inch rims, while the largest option uses a 16-inch rim, so confirming the truck's actual wheel setup comes first. Once that is settled, the decision shifts to the right radial style, sidewall treatment, and product type for the way the truck is driven and presented.
In 215/75R15, the 215 is the section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 15 is the rim diameter in inches. This is a modern metric radial size used on certain 1998 Toyota Trucks T100 4x2 applications and it gives the truck a smaller 15-inch wheel fitment than the 16-inch option used elsewhere. Available choices range from all-terrain raised white letter styling to narrow and wide whitewall radials from brands such as BFGoodrich, Coker Classic, American Classic, Maxxis, Tornel, and Travelstar. It is the size to evaluate when the truck is a 15-inch-wheel 4x2 and the goal is to balance utility, appearance, and correct wheel compatibility.
The 235/75R15 size uses a 235-millimeter section width, a 75-series profile, radial construction, and a 15-inch rim. On the 1998 Toyota Trucks T100, this is the broadest-reaching 15-inch fitment and appears across several 4x2 and 4x4 configurations, making it a common decision point for owners with factory-style 15-inch wheels. Product selection is wide, including BFGoodrich all-terrain offerings, whitewall radials in both narrow and wide treatments, and several classic-style series from Coker Classic, American Classic, Maxxis, Tornel, and Travelstar. This size deserves a close look when the truck needs 15-inch radial fitment with the most choice in sidewall style and tire character.
A 265/70R16 tire has a 265-millimeter section width, a 70-series profile, radial construction, and fits a 16-inch rim. On the 1998 Toyota Trucks T100, this size belongs to specific 4x4 applications and immediately signals the need to confirm that the truck is on the correct 16-inch wheel rather than one of the 15-inch setups. The available choice here centers on BFGoodrich's All-Terrain T/A KO2 with raised white letters, giving the size a more truck-oriented and utility-focused presentation than the whitewall-heavy 15-inch sizes. It is the right path to evaluate when keeping a 4x4 on its larger wheel and matching the tire to that heavier-duty look.
Sub-model fitment on the 1998 Toyota Trucks T100 is not completely uniform, because tire choice changes by drivetrain and wheel setup. Checking whether the truck is a 4x2, 4x4, SR5 4x2, or SR5 4x4 helps narrow the correct size before comparing sidewall style or product type.

1998 Toyota Trucks T100 4x2
The 1998 Toyota Trucks T100 4x2 uses 15-inch radial fitments, with either 215/75R15 or 235/75R15 depending on the truck's setup. That makes wheel confirmation especially important before choosing between all-terrain styling and the broader mix of narrow or wide whitewall radial options available in these sizes.
The 1998 Toyota Trucks T100 4x4 can use either 235/75R15 or 265/70R16 radial tires, so both sub-model identification and rim diameter matter. The practical choice comes down to confirming whether the truck is on a 15-inch or 16-inch wheel before selecting a tire with the right appearance and intended use.
The 1998 Toyota Trucks T100 SR5 4x2 uses 235/75R15 radial tires, which keeps fitment more straightforward than the multi-size configurations. Once that size is confirmed, the main decision becomes whether to choose an all-terrain raised white letter look or one of the many narrow or wide whitewall radial styles.
The 1998 Toyota Trucks T100 SR5 4x4 shares the same two-size fitment pattern as other 4x4 configurations, using either 235/75R15 or 265/70R16. Tire selection starts with verifying the actual wheel diameter on the truck, then moves to choosing between a 15-inch classic-style radial presentation or the 16-inch all-terrain setup.
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 1998 Toyota Trucks T100 Tires for Sale
Available 1998 Toyota Trucks T100 tires are all radial, with choices that range from BFGoodrich All-Terrain T/A KO2 raised white letter tires to classic-style whitewall offerings from Coker Classic, American Classic, Maxxis, Tornel, and Travelstar. The widest variety appears in the 15-inch sizes, while 265/70R16 stays focused on a truck-oriented all-terrain option.
Owners of a 1998 Toyota Trucks T100 usually need to sort out the correct tire size by sub-model and wheel diameter first, then compare radial styles, sidewall treatments, and practical fitment checks. These answers focus on that exact buying path.
Tire Size & Fitment
What tire size fits a 1998 Toyota Trucks T100?
A 1998 Toyota Trucks T100 uses one of three radial tire sizes: 215/75R15, 235/75R15, or 265/70R16. The correct size depends on the exact sub-model and wheel setup. The 4x2 uses 215/75R15 or 235/75R15, the 4x4 uses 235/75R15 or 265/70R16, the SR5 4x2 uses 235/75R15, and the SR5 4x4 uses 235/75R15 or 265/70R16.
That means the first step is confirming both the sub-model and the truck's actual wheel diameter. A T100 that has had wheels changed over the years may not still wear its original-size rim, so checking the tire sidewall and the wheel itself is smarter than assuming by appearance alone. Once the size is confirmed, the remaining choice is the right radial style for the truck's intended use and visual presentation.
What size rim does a 1998 Toyota Trucks T100 use?
The 1998 Toyota Trucks T100 uses either a 15-inch or 16-inch rim, depending on tire size. Both 215/75R15 and 235/75R15 fit 15-inch wheels, while 265/70R16 fits a 16-inch wheel. The truck does not use one universal rim diameter across all configurations, so the wheel size has to match the tire size exactly.
Rim diameter is the fitment detail to confirm before anything else, especially on a truck with multiple valid tire sizes. A 15-inch tire will not mount on a 16-inch wheel, and a 16-inch tire will not mount on a 15-inch wheel. It also helps to compare wheel width with the tire's supported rim-width range, particularly if the truck has aftermarket wheels or a previous owner changed the original setup.
Do all 1998 Toyota Trucks T100 sub-models use the same tire size?
No, the 1998 Toyota Trucks T100 does not use one tire size across every sub-model. The SR5 4x2 uses 235/75R15, while the 4x2, 4x4, and SR5 4x4 can have more than one applicable size. The biggest split is between the 15-inch sizes and the 16-inch 265/70R16 fitment used on certain 4x4 configurations.
That variation matters because the right tire is tied to both sub-model and wheel diameter, not just the badge on the truck. Owners should verify whether the T100 is a 4x2 or 4x4, then confirm the wheel size currently on the vehicle. After that, comparing tread style, whitewall treatment, or raised white letter presentation becomes much easier and far less likely to lead to the wrong purchase.
Choosing the Right Tire
What should I consider when choosing a tire for a 1998 Toyota Trucks T100?
Start with the correct size for the truck's exact sub-model and wheel diameter: 215/75R15, 235/75R15, or 265/70R16. All of the applicable tires are radials, so the next decision is less about construction type and more about intended use, sidewall appearance, and how truck-oriented or classic-styled the finished look should be.
A T100 used for general road driving may point the buyer toward one of the classic-style whitewall radials in the 15-inch sizes, while a truck meant to keep a tougher utility look may lean toward the BFGoodrich All-Terrain T/A KO2. It also helps to compare rim-width compatibility, maximum load figures at the stated pressure, and the truck's present wheel setup before narrowing the field.
What sidewall styles are available for 1998 Toyota Trucks T100 tires?
Sidewall choices for the 1998 Toyota Trucks T100 include RBL, RWL, narrow whitewall, and wide whitewall, depending on tire size. The 15-inch sizes have the most variety, with both narrow and wide whitewall radials as well as truck-style BFGoodrich options. The 265/70R16 fitment is more focused, using a raised white letter all-terrain presentation.
That gives the T100 owner two very different visual directions. A narrow or wide whitewall can create a more customized, retro, or specialty-truck look, while raised white letters keep the truck in a more traditional light-truck appearance. The smart approach is to settle the correct size first, then choose a sidewall style that matches the truck's finish, stance, and how period-inspired or utilitarian the final presentation should be.
What brands offer tires for the 1998 Toyota Trucks T100?
Available brands for the 1998 Toyota Trucks T100 include BFGoodrich, Coker Classic, American Classic, Maxxis, Tornel, and Travelstar. Brand choice depends in part on tire size, since the 15-inch fitments have several classic-style options across multiple makers, while the 265/70R16 fitment is represented by BFGoodrich in an all-terrain series.
The practical way to compare brands is by what each one offers in the exact size the truck needs. Some focus on whitewall styling, others on a truck-oriented tread and raised white letters, and some differ in stated rim-width range, load figure, or tire series character. Choosing among them is less about ranking the name and more about matching the tire's look and specifications to the T100's real setup.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Toyota Trucks T100?
For a period-style 1998 Toyota Trucks T100, the starting point is still the correct radial size for the truck's sub-model and wheel diameter. From there, the 15-inch sizes offer the broadest range of appearance choices, including narrow whitewall and wide whitewall radials, while 265/70R16 stays closer to a truck-focused all-terrain look with raised white letters.
The right choice depends on what kind of period presentation the truck is aiming for. A cleaner street-oriented build may suit one of the whitewall radials, while a more utility-minded T100 may look more at home on an all-terrain raised white letter tire. When exact historical appearance matters, checking original sales literature, surviving trucks, or marque-specific references is worthwhile before settling on a sidewall treatment.
How does tire construction affect the appearance of a restored 1998 Toyota Trucks T100?
On the 1998 Toyota Trucks T100, tire construction is straightforward because the applicable fitments are radial. That means the visual difference comes less from choosing between bias-ply and radial and more from selecting the sidewall style, tire series, and overall tire character within the proper radial size for the truck.
A whitewall radial can shift the truck toward a customized or retro-inspired look, while a raised white letter all-terrain tire gives it a more traditional late-1990s truck presence. The important thing is not to treat appearance as separate from fitment. Getting the correct size and wheel diameter first preserves the truck's stance and proportions, then the sidewall treatment can refine the look without forcing the wrong tire onto the wrong setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Toyota Trucks T100?
Yes, modifications can change tire fitment on a 1998 Toyota Trucks T100 even when the tire size is otherwise correct for the model. Aftermarket wheels, changes in wheel width or offset, suspension lifts or lowering, and body or fender alterations can all affect how a 215/75R15, 235/75R15, or 265/70R16 tire sits and clears the truck.
That is especially important on a T100 with multiple valid factory-style sizes, because the truck may no longer have the wheel diameter it originally left with. Checking wheel size, wheel width, steering clearance, and suspension travel before installing new tires helps prevent rubbing or mismatch problems. A truck that has been modified should always be measured as it sits, not chosen by sub-model alone.
What should I inspect before driving a 1998 Toyota Trucks T100 on new tires?
Before driving a 1998 Toyota Trucks T100 on new tires, inspect the wheels for correct diameter and condition, verify proper tire pressure, and make sure there is no interference at full steering lock. It is also smart to look over suspension and steering components, since worn shocks, bushings, or alignment problems can affect how a new set of tires behaves on the road.
A short local test drive is a good final check before putting more miles on the truck. Listen for rubbing, feel for pulling or vibration, and recheck air pressure after the first outings. On an older pickup that may have seen wheel changes or mixed replacement parts over time, a little extra inspection up front helps confirm that the new tires are working with the truck rather than exposing an existing setup issue.
How often should tires on a 1998 Toyota Trucks T100 be inspected?
Tires on a 1998 Toyota Trucks T100 should be inspected regularly, not just when tread looks low. A quick visual check before driving and a more careful inspection at routine service intervals helps catch cracking, cuts, bulges, uneven wear, or slow air loss before they become bigger problems. That matters on both lightly used collector trucks and regularly driven workhorse examples.
Older trucks often spend time parked, and inactivity can be just as hard on tires as mileage. Pressure should be checked consistently, and the sidewalls deserve close attention if the truck is stored for long periods or kept outdoors. Looking over the tires after seasonal changes, before longer drives, and after any suspension or wheel work helps keep the T100's fitment and road manners in a dependable range.
