The 1998 Infiniti Trucks QX4 arrived as a premium midsize SUV with a more upscale presentation than many truck-based utilities of its era, blending everyday comfort with genuine all-terrain capability. That mix still shapes tire choice today, because the right tire has to suit both the QX4’s road manners and its light-truck roots. This model uses a 245/70R16 radial on a 16-inch rim, so the focus is less about sorting through multiple factory sizes and more about choosing the right version of that size. For many owners, that means balancing all-terrain character, raised white letter styling, and practical road use with the vehicle’s current wheel setup and condition.
Which Tire Size Is Right for The 1998 Infiniti Trucks QX4
The 1998 Infiniti Trucks QX4 uses one primary tire size: 245/70R16, a radial tire for a 16-inch rim. That same size applies to the covered Base sub-model, so the main decision is choosing the right tire within the correct fitment rather than sorting between multiple sizes. For most buyers, the next step is comparing tire style, intended use, rim-width compatibility, and overall vehicle setup.
245/70R16 is a metric radial size in which 245 identifies the section width in millimeters, 70 is the aspect ratio, R designates radial construction, and 16 is the rim diameter in inches. On the 1998 Infiniti Trucks QX4, this size matches the vehicle’s primary radial fitment and suits the SUV’s blend of street use and utility. Available choices in this size include BFGoodrich’s All Terrain TA KO2 with raised white letter sidewall styling. It is the right starting point for an owner who wants to stay with the original fitment format while selecting a tire that matches the QX4’s current use and wheel specifications.
Sub-model fitment is straightforward for the 1998 Infiniti Trucks QX4. The covered sub-model uses the same primary tire size, so tire selection is mostly about choosing the right tire type and confirming the vehicle still has the correct 16-inch wheel setup.

Tire Size & Fitment
What tire size fits a 1998 Infiniti Trucks QX4?
The 1998 Infiniti Trucks QX4 uses a 245/70R16 radial tire. That size is the primary fitment for this vehicle and pairs with a 16-inch rim, giving the QX4 a modern metric radial setup rather than an older bias-ply or alphanumeric format.
Choosing the correct size is only the first step. It is still important to confirm that the SUV retains the proper 16-inch wheels and that wheel width, tire clearance, and overall condition match the intended tire choice, especially if the vehicle has seen aftermarket wheel changes, suspension work, or years of mixed replacement parts.
What size rim does a 1998 Infiniti Trucks QX4 use?
The 1998 Infiniti Trucks QX4 uses a 16-inch rim with its 245/70R16 tire size. In the available product selection for this fitment, the tire is built around a 16-inch rim diameter and a rim-width range of 6.5 to 7.0 inches.
Rim diameter has to match exactly, so a different wheel diameter calls for a different tire size altogether. Wheel width also matters, because even when the diameter is correct, an improperly sized wheel can affect tire shape, clearance, and overall fitment, making it worth checking the actual wheels on the vehicle before replacing tires.
Does the 1998 Infiniti Trucks QX4 Base use the same tire size?
Yes. The 1998 Infiniti Trucks QX4 Base uses the same 245/70R16 radial tire size as the core fitment for this model. That makes sub-model fitment straightforward and keeps the buying decision centered on tire type, construction, and intended use rather than on multiple original size choices.
Even with shared sub-model sizing, the actual vehicle should still be checked before purchase. A QX4 that has been modified with different wheels, changed ride height, or non-stock suspension parts may need closer review of wheel width and tire clearance, even though the original fitment size for the Base model remains 245/70R16.
Choosing the Right Tire
What should I consider when choosing a 245/70R16 tire for a 1998 Infiniti Trucks QX4?
Start with the correct size and construction: 245/70R16 radial on a 16-inch wheel. From there, the main considerations are how the QX4 is used, whether the tire’s load capability suits the vehicle, and whether the wheel width matches the tire’s intended application.
Appearance and driving purpose matter too. An owner who wants a more truck-oriented look may prefer an all-terrain design, while a mostly street-driven QX4 may call for a calmer overall presentation. Checking sidewall style, tire weight, and the actual wheel dimensions helps narrow the choice without drifting away from the proper fitment.
What sidewall styles are available for 1998 Infiniti Trucks QX4 tires?
The available 245/70R16 fitment for the 1998 Infiniti Trucks QX4 includes RWL sidewall styling, which means raised white letters. That gives the tire a more traditional light-truck appearance than a plain blackwall and can change the visual character of the vehicle even when the size remains the same.
Sidewall style is mostly an appearance decision, but it should still be made after confirming the tire’s basic specifications. A raised white letter tire can suit a period-appropriate late-1990s SUV look, while the more important checks remain size, wheel compatibility, load rating, and whether the tread style matches how the QX4 is actually driven.
What brands offer tires for the 1998 Infiniti Trucks QX4?
The current 245/70R16 fitment selection for the 1998 Infiniti Trucks QX4 includes BFGoodrich. In this application, the available tire is from the All Terrain TA KO2 series, giving the QX4 a recognizable all-terrain option within the correct radial size and 16-inch rim diameter.
Brand is only one part of the decision. It still helps to compare the series character, sidewall presentation, load figure, and approved rim-width range against the actual vehicle. That approach keeps the focus on fitment and intended use, which is especially important for an older SUV that may no longer be riding on its original wheels.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Infiniti Trucks QX4?
A period-style approach for a 1998 Infiniti Trucks QX4 starts with the original fitment size, 245/70R16, on the correct 16-inch wheel. Staying with the proper metric radial format preserves the late-1990s SUV look more effectively than moving to an unrelated size or an overly aggressive altered setup.
From there, the visual choice comes down to how traditional or truck-oriented the finished vehicle should appear. An all-terrain radial with raised white letters can suit the era well, but owners pursuing strict originality should compare tire appearance against period photos, brochures, or marque-specific references before settling on a final style.
How does tire construction affect the appearance of a restored 1998 Infiniti Trucks QX4?
On a restored 1998 Infiniti Trucks QX4, radial construction is part of the vehicle’s proper visual and functional character. The factory-era fitment style is already a modern metric radial, so keeping that construction maintains the expected sidewall shape and overall stance more naturally than trying to force in an older-looking tire concept.
Appearance still varies within radial options, especially through tread design and sidewall treatment. Raised white letters create a more rugged, period-flavored truck look, while a simpler sidewall gives a cleaner presentation. Keeping the correct 245/70R16 sizing matters just as much as the construction itself when the goal is a balanced, authentic-looking restoration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Infiniti Trucks QX4?
Yes. A 1998 Infiniti Trucks QX4 may have started with 245/70R16 tires on 16-inch wheels, but aftermarket wheels, altered wheel width, suspension changes, or ride-height adjustments can change how that size fits in actual use. Even when the sidewall size looks correct, the full setup can still differ from stock.
Checking the vehicle in person is the safest approach before replacing tires. Wheel diameter and width should be confirmed first, followed by steering clearance, fender clearance, and the condition of suspension components. Those checks matter most on older SUVs, where previous owners may have made changes that are not obvious at a glance.
What should I inspect before driving a 1998 Infiniti Trucks QX4 on new tires?
Before putting a 1998 Infiniti Trucks QX4 back into regular use on new tires, inspect the wheels for correct diameter and general condition, then check for proper inflation, even tread seating, and any signs of rubbing at full steering lock. It also helps to look over suspension and steering components for looseness or wear.
A tire can only perform as intended if the rest of the vehicle is ready for the road. Brake condition, alignment, wheel fastener torque, and valve stem condition are all worth checking, especially on a vehicle that has sat for long periods. A careful walkaround after the first short drive can reveal air loss or clearance issues early.
What should I check before a longer drive in a 1998 Infiniti Trucks QX4?
Before a longer drive, the 1998 Infiniti Trucks QX4 should have its tires checked for proper pressure, visible damage, uneven wear, and any signs of cracking, bulges, or slow air loss. The wheels and tires should also be inspected for clearance problems that may only appear when the vehicle is loaded or turned sharply.
Longer trips put more heat and stress into an older SUV’s tires and chassis than short local drives. Looking over the spare, confirming that the wheels are secure, and making sure the suspension feels stable can prevent small issues from becoming roadside problems. That is especially important when the QX4 has not been driven regularly.
