1998 Acura Trucks Tire Fitment Guide

1998 Acura Trucks vehicles use one tire size: 245/70R16, and it applies to the SLX. That size mounts on a 16-inch wheel, and the available product for it is built for a rim-width range of 6.5 to 7.0 inches. Because there is only one fitment at the year-and-make level, there is no factory-size split to sort through here.

That makes the process simpler than it is on many year-make pages. If your Acura still wears its original wheel diameter, 245/70R16 is the starting point; if it has aftermarket wheels, confirm the wheel diameter and width before moving ahead. A quick check of the sidewall on the current tires and the wheel itself will usually tell you whether your SLX still matches the original 16-inch fitment.

On a 1998 Acura Trucks SLX, 245/70R16 is a metric radial size. The 245 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. That gives you both the tire's general profile and the wheel size it is built to fit.

For an SLX owner, the most important takeaway is that the 16-inch wheel diameter is non-negotiable for this size. The width and profile also affect the vehicle's stance and overall look, so changing away from this sizing format usually means moving away from the original fitment. If your goal is to keep the truck close to factory proportions, matching the full 245/70R16 size matters, not just the 16-inch wheel diameter.

Yes. At the 1998 Acura Trucks level, the SLX uses 245/70R16, so there is no model-to-model tire-size variation to navigate within this year and make. The fitment centers on a single radial size on a 16-inch wheel rather than multiple widths, profiles, or rim diameters.

That consistency is helpful when you know you have a 1998 Acura SLX but have not yet sorted out every trim or equipment detail. Even so, it is still smart to inspect the vehicle before replacing tires, because many older SUVs have seen wheel changes over the years. If the current wheels are not 16-inch wheels in the proper width range, the original tire size may no longer be the correct physical fit for the truck as it sits today.

The available 245/70R16 tire for 1998 Acura Trucks comes with an RWL, or raised white letter, sidewall. That sidewall treatment gives the SLX a more rugged sport-utility look than a plain blackwall, even though the vehicle itself was positioned as a more upscale import SUV. There is no sidewall-style split at this year-and-make level.

Whether that look is right for your Acura depends on how you want the truck to present. An owner leaning toward an era-correct late-1990s SUV appearance may appreciate white letters, while someone pursuing a cleaner luxury look may prefer to compare what is already on the vehicle and decide whether visual consistency matters. Sidewall style will not change the basic fitment, but it absolutely changes the finished look of the truck.

BFGoodrich currently covers the 245/70R16 fitment used on 1998 Acura Trucks SLX models. The tire available in that size is from the All-Terrain T/A KO2 family, which places it in a well-known light-truck and SUV line rather than a purely touring-oriented product. For this year and make, the fitment is narrow and straightforward rather than spread across multiple brands and constructions.

That means the buying decision centers less on comparing a long brand roster and more on deciding whether the BFGoodrich tire's character suits your SLX. If your Acura is used for regular road driving with occasional rough-road or mixed-surface use, the all-terrain identity may be appealing. If your priority is preserving a very specific original visual style, compare the tire's raised white letters and tread character against your restoration goals before choosing.

For 1998 Acura Trucks, the BFGoodrich All-Terrain T/A KO2 in 245/70R16 combines radial construction, an S speed rating, an RWL sidewall, a 2,535-pound maximum load at 65 psi, and a 44-pound tire weight. That places it firmly in a light-truck all-terrain category rather than a soft-looking highway touring presentation. The fitment remains correct for the SLX's 16-inch wheel diameter, but the visual and use-case character is more rugged than some owners may expect from an Acura-badged SUV.

In practical terms, that means the KO2 makes sense for owners who want durability, an assertive period-SUV look, and a tire that visually complements the SLX's truck-based roots. Owners trying to preserve a more restrained luxury-SUV appearance may focus more closely on sidewall presentation and tread character when evaluating whether this tire matches the truck's personality. The decision is less about basic fit and more about how you want the finished vehicle to look and feel.

The 245/70R16 tire used on 1998 Acura Trucks fits a 16-inch rim and is intended for a rim-width range of 6.5 to 7.0 inches. That width range matters because it supports the tire's designed profile and helps keep the tread shape and sidewall behavior where they should be. A correct wheel diameter alone is not enough if the wheel is too narrow or too wide.

Before replacing tires on a 1998 Acura SLX, confirm the actual wheel width rather than assuming every 16-inch wheel is interchangeable. This is especially important if the truck has changed hands several times or wears aftermarket wheels. Verifying width first helps avoid mounting a proper tire size on an improper wheel, which can alter appearance, road feel, and how the tire carries load.

The available 245/70R16 tire for 1998 Acura Trucks does not carry a tube-type marking in the size notation, so there is no sign here of a dedicated inner-tube fitment. That places the setup in line with the tubeless radial norm for a late-1990s luxury SUV. The wheel itself still needs to be in good condition, with a sound valve stem and sealing surfaces.

For a 1998 Acura SLX, the more useful check is wheel condition rather than tube compatibility. If the original wheels are corroded, bent, or damaged around the bead seat, even the correct tire may not seal or balance as it should. Any truck that has sat for long periods also deserves fresh valve stems and a careful inspection of the spare before being put back into regular service.

A 1998 Acura Trucks SLX should be stored clean, dry, and out of direct sunlight, with the tires kept away from electric motors, ozone-producing equipment, and strong solvents. Radial tires generally tolerate inactivity better than bias-ply tires, but long static storage can still lead to flat spotting, sidewall aging, and pressure loss. Keeping the truck on a cool concrete floor is fine if the area stays dry and the tires remain properly inflated.

If the Acura will sit for months at a time, move it periodically so the load does not rest on the same contact patch continuously, or use stands if the storage plan is long term and done correctly. Check inflation before and after storage rather than assuming a parked SUV is ready to drive. Collector vehicles often age their tires through time and environment more than miles, so storage habits matter almost as much as road use.

Tires on a 1998 Acura Trucks should be judged primarily by age, condition, and storage history rather than mileage alone. A sensible collector-vehicle rule is to begin evaluating tires closely once they reach roughly five to seven years of age and to treat ten years as the point where replacement deserves serious consideration, even if tread remains. The DOT date code on the sidewall is the simplest way to confirm age.

That approach matters because many SLX models are driven occasionally, not daily, so tread wear can look deceptively light while the rubber itself has hardened or begun to crack. Sidewall condition, ride quality, and pressure retention are often more revealing than remaining tread depth on a low-use SUV. If the Acura has spent years parked indoors and still appears healthy, inspection still matters; age alone should never be ignored.

Tires on a 1998 Acura Trucks should be inspected before every drive and again before any longer highway outing. Look for cracking, cuts, bulges, uneven wear, low pressure, and anything embedded in the tread, and make sure the valve stems are not weathered or leaking. A low-use SLX can hide age-related tire problems surprisingly well until the truck returns to regular road speeds.

A quick visual check is useful, but a hands-on pressure check and periodic close sidewall inspection are even more important. If the Acura has been sitting, inspect the spare as carefully as the road tires, since many emergency spares age out unnoticed. Regular inspections are cheap insurance on an older SUV whose braking, steering, and suspension all depend on a sound tire contact patch.

The 245/70R16 tire used on 1998 Acura Trucks carries an S speed rating, which corresponds to a 112 mph maximum speed capability under proper conditions. That is more than adequate for normal U.S. highway use in a healthy Acura SLX, assuming the tires are in good condition and properly inflated. As with any late-1990s SUV, overall road safety depends on the full vehicle system, not the tire alone.

On an older SLX, braking condition, suspension wear, steering play, alignment, and age-related rubber deterioration elsewhere on the chassis may affect confidence long before the tire's speed symbol becomes the limiting factor. The smarter question is not whether the tire can survive highway speed in theory, but whether the entire truck is prepared for sustained road use. A fresh inspection and realistic expectations go much further than chasing a higher speed rating.

For the available 245/70R16 tire on a 1998 Acura Trucks SLX, the maximum load capacity is 2,535 pounds at 65 psi. That figure is the tire's load-and-pressure rating, not automatically the pressure you should run in everyday service. Factory vehicle pressure recommendations can be lower, and they are the right starting point for a stock vehicle on stock-type fitment.

Use the Acura door-jamb or owner's-manual recommendation as your baseline, then confirm the tire manufacturer's guidance if the vehicle has been modified or used for heavier loads. Do not transfer a pressure number from another SUV or another tire size, even if the dimensions look similar. Correct pressure affects handling, tread wear, and braking, and it is one of the easiest ways to preserve both safety and tire life on an older SLX.

Before a longer trip in a 1998 Acura Trucks SLX, inspect each tire for sidewall cracking, cuts, bulges, uneven wear, and proper inflation, and make sure the spare is usable. Check valve stems, confirm the tires are holding pressure, and look for signs of impact damage from curb contact or potholes. The tire itself is only one part of the equation, but it is the part in direct contact with the road.

A good pre-drive routine also includes wheel-lug security, brake condition, fluid levels, belts, hoses, and a quick look at suspension and steering components. Older SUVs often feel fine around town while hiding issues that show up only after heat and distance build. Starting with a careful tire inspection is sensible because it catches obvious trouble early and helps the rest of the vehicle do its job safely.
