1998 Infiniti Trucks Tire Fitment Guide

1998 Infiniti Trucks vehicles use one tire size: 245/70R16. That size applies to the 1998 Infiniti Trucks QX4, so there is no split fitment to sort through at the year-and-make level. The tires mount on a 16-inch rim, and the available rim-width range for the product offered in this size is 6.5 to 7.0 inches.

That makes the fitment process much simpler than on many vintage and specialty vehicles. The main things to verify are that your truck is a 1998 QX4, your wheels are 16-inch wheels, and the wheel width falls within the tire's approved range. Once those basics are confirmed, your choice becomes more about tread style and intended driving use than about comparing multiple original sizes.

On a 1998 Infiniti Trucks tire, 245/70R16 is a metric radial size. The 245 is the nominal section width in millimeters, 70 is the aspect ratio, the R indicates radial construction, and 16 is the wheel diameter in inches. In the available example for this size, the service description includes a 113S rating, with S indicating a speed capability up to 112 mph.

For an owner, that code matters because it ties together the tire's width, sidewall proportion, and wheel fitment. It also helps separate a correct late-1990s metric radial fitment from older numeric or alphanumeric sizing systems used on earlier collector vehicles. Matching the full size code is the safest starting point before you compare sidewall appearance, tread character, or load capacity.

Yes. The 1998 Infiniti Trucks range consists of the QX4, and it uses 245/70R16. There is no second model in the lineup for that year that introduces a different factory tire size at the year-and-make level, so the fitment path is consistent throughout the range.

That consistency is useful if you already know you have a 1998 Infiniti QX4 but have not yet checked every tire marking on the truck. Even so, it is smart to confirm what is actually mounted on your wheels today, especially if the vehicle has changed hands or has seen previous wheel and tire updates. A visual check of the sidewall and wheel diameter prevents avoidable mismatches.

The available 245/70R16 tire for 1998 Infiniti Trucks comes with an RWL sidewall, meaning raised white letters. That look was a familiar late-1990s truck and SUV styling cue, especially on all-terrain and utility-oriented tires, and it suits the QX4's blend of upscale trim and genuine SUV capability.

Sidewall style affects the vehicle's appearance more than its base fitment, so the choice often comes down to whether you want a more period-right sport-utility look or a subtler presentation. If appearance matters to your restoration or driver build, compare the sidewall treatment to period photos of similar QX4s and decide whether the more visible white-letter look matches the stance you want.

BFGoodrich currently covers the 245/70R16 size used on 1998 Infiniti Trucks QX4 models. The available example is from the All-Terrain T/A KO2 line, which pairs the QX4's 16-inch fitment with a more rugged truck-oriented tread and an RWL sidewall presentation.

For a buyer, that means the conversation is less about sorting through many brands in this exact year-make-size combination and more about deciding whether that tire's character matches the way the truck is used. A QX4 that spends time on rougher secondary roads may benefit from that all-terrain personality, while a more preservation-focused truck owner may weigh appearance just as heavily as tread style.

For 1998 Infiniti Trucks, the BFGoodrich All-Terrain T/A KO2 in 245/70R16 brings a truck-focused all-terrain design, RWL styling, a 113S speed rating, a 2,535-pound load rating at 65 psi, and a 44-pound casing. Those traits point to a tire built with utility and load support in mind rather than a softer, more road-biased touring emphasis.

That distinction matters because a QX4 can live very different lives today. If the truck is used for mixed-surface driving, winter-region use, or a tougher visual stance, an all-terrain tire is often the natural fit. If your priority is a more subdued everyday-road feel, the question becomes whether you want to stay with the more rugged character or search the broader replacement market by size and specification.

The available 245/70R16 fitment for 1998 Infiniti Trucks is approved for rims that are 6.5 to 7.0 inches wide. Rim width matters because the same 16-inch diameter does not automatically mean every wheel presents the tire with the proper sidewall shape and tread profile.

Checking wheel width before mounting is especially important on older used SUVs, where previous owners may have swapped wheels for appearance or off-road use. A tire mounted on a wheel outside its approved width range can change the way the sidewall sits and how the tread meets the road. Confirming both diameter and width is the cleanest way to avoid setup issues.

The available 245/70R16 radial for 1998 Infiniti Trucks does not show a tube-type marking, and this late-1990s SUV fitment is consistent with tubeless radial practice. That aligns with the era and the construction style used on the QX4, which was built long after tube-type fitments had ceased to be normal on mainstream passenger and light-truck applications.

Even so, wheel condition still matters. If a truck has wheel corrosion, damage at the bead seat, or a nonstandard wheel that has been fitted later in life, sealing quality can be affected regardless of whether the tire itself is tubeless. Inspect the wheel carefully and replace valve stems during mounting so the whole assembly starts with the best possible air-retention foundation.

A 1998 Infiniti Trucks QX4 should be stored away from direct sunlight, ozone sources such as electric motors and battery chargers, and persistent moisture. Clean, dry concrete or a barrier between the tires and bare floor helps, and moving the truck periodically can reduce long-term stress in one contact patch area. Radials usually resist temporary flat-spotting better than older bias-ply designs, but age and environment still matter.

Storage habits have a real effect on sidewall condition and long-term ride quality. If the truck will sit for extended periods, keep the tires at proper pressure, avoid overloading the vehicle during storage, and inspect for cracking before the next drive. Owners who maintain several collector vehicles often rotate which one gets exercised each month so no single set of tires sits motionless for too long.

Tires on a 1998 Infiniti Trucks QX4 should be judged more by age and condition than by mileage alone, especially if the truck is driven occasionally. A useful rule is to begin careful age-related evaluation around five to seven years and to treat about ten years as the point where replacement deserves serious consideration, even if tread remains. The DOT date code on the sidewall is the reference for tire age.

That matters because many low-mile collector and enthusiast SUVs appear healthy at a glance while carrying tires that are simply too old to trust. Sidewall checking, hardened rubber, and reduced wet-weather confidence can develop long before tread depth looks exhausted. If the truck has recently come out of storage or changed ownership, checking the date code is one of the smartest first steps you can take.

Tires on a 1998 Infiniti Trucks QX4 should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, punctures, bulges, uneven wear, and any sign that the tire has been run underinflated. Pressure should be checked cold, since a tire that slowly loses air can still look normal on a parked SUV.

Frequent inspection is especially important on older enthusiast vehicles because they often spend more time parked than daily-driven modern cars. A quick walk-around can catch a problem before it becomes a roadside issue, and a more thorough seasonal inspection helps you see age-related changes developing over time. If the truck still carries an original-style spare, inspect that tire too rather than assuming it is ready for service.

The 1998 Infiniti Trucks QX4 belongs to the era when metric radial tires were standard equipment, and 245/70R16 is the year-and-model fitment used here. A modern radial in that same size reflects the construction type and general sizing convention the vehicle was designed around. Original-equipment branding could vary by market and production details, so the safest authenticity focus is the correct size, radial construction, and era-appropriate overall look.

Owners pursuing a highly accurate restoration should compare surviving original photos, window stickers, and marque-club knowledge before making a final cosmetic decision. For most late-1990s SUVs, judges and knowledgeable enthusiasts will notice a wrong overall size or an obviously out-of-era sidewall treatment long before they debate fine points of tread pattern. Getting the size and construction right puts the truck on solid footing.

Yes, correct tire fitment matters when showing a 1998 Infiniti Trucks QX4, even though it is newer than many traditional collector vehicles. Judges and informed enthusiasts often look first at whether the tire size, construction type, and sidewall presentation make sense for the year and market position of the truck. On a late-1990s luxury SUV, an obviously oversized or visually mismatched tire can change the stance enough to distract from an otherwise accurate presentation.

That does not mean every event applies the same standards. A preservation gathering, a marque event, and a casual local show may care about different details, so event-specific expectations are worth checking ahead of time. If authenticity is your goal, keeping the QX4 on the correct 245/70R16 radial format and choosing a sidewall style that feels period-appropriate will usually matter more than chasing novelty.

For a 1998 Infiniti Trucks QX4, an all-terrain tire such as the BFGoodrich All-Terrain T/A KO2 keeps the correct basic size but shifts the truck's visual and functional character toward a more aggressive utility look. Its RWL sidewall and truck-oriented tread can feel very at home on a body-on-frame SUV, but they create a different impression than a milder road-focused tire in the same size.

That distinction matters in restoration because authenticity is often about the whole visual package, not just whether the size matches. A driver-oriented QX4 can wear an all-terrain tire honestly and convincingly, while a showroom-style presentation may call for a less assertive look. Owners aiming for event-level originality should compare period photos and consult Infiniti enthusiast communities to settle the appearance question.

The available 245/70R16 tire for 1998 Infiniti Trucks carries an S speed rating, which corresponds to 112 mph. That places it comfortably within normal U.S. highway use when the tire is in good condition, properly inflated, and matched to a sound vehicle. On a 1998 QX4, the larger real-world safety factors are often tire age, inflation condition, alignment, suspension wear, and the truck's overall mechanical state rather than the raw speed symbol alone.

Highway confidence comes from the whole package working together. A fresh radial with an appropriate load rating is only part of the story if the truck has tired shocks, aging bushings, or brake issues that affect stability and stopping distance. Before regular interstate use, make sure the tires are recent enough, the pressures are correct, and the vehicle itself is ready for sustained-speed driving.

The available 245/70R16 tire for 1998 Infiniti Trucks is rated for 2,535 pounds at 65 psi, which is the tire's maximum load-and-pressure figure rather than a blanket operating recommendation for every QX4. That number tells you the tire's upper load capability at its rated pressure, but it should not automatically be treated as the day-to-day pressure target for normal driving.

For actual use, start with the factory vehicle recommendation from the original owner's literature or door-jamb information, then compare it with the tire manufacturer's guidance for that product. Running every tire at maximum sidewall pressure can alter ride and contact patch behavior if the vehicle does not require it. The important point is to use a pressure appropriate to the vehicle, the load carried, and the specific tire's design.

Before a longer drive in a 1998 Infiniti Trucks QX4, inspect each tire for cracking, embedded objects, cuts, bulges, irregular wear, and proper cold inflation pressure. Confirm that the spare is usable, that the valve stems are sound, and that no tire shows signs of age-related deterioration. On a truck of this era, it is also wise to look beyond the tires and consider brakes, belts, hoses, fluid levels, and suspension condition.

That pre-drive routine reduces the chance that a minor issue becomes a trip-ending one. A highway run places more continuous heat and load into a tire than short local driving, so weaknesses tend to reveal themselves there first. If the QX4 has been sitting, drive a short local shakedown trip before committing to distance, then recheck pressures and give the tires one more close visual inspection.
