2024 Acura Trucks Tire Fitment Guide

2024 Acura Trucks vehicles use seven sizes across three models. The MDX uses 255/55R19, 255/50R20, and 275/40R21; the RDX uses 235/55R19 and 255/45R20; and the ZDX uses 265/50R20 and 275/40R22. These are all radial sizes, but they do not interchange across the full Acura lineup because each model has its own fitment range and wheel diameters span 19, 20, 21, and 22 inches.

That means the first fitment step for a 2024 Acura Trucks vehicle is identifying the exact model and the wheel diameter currently on the SUV. Even where two models use the same nominal rim diameter, the tire size itself can still differ. Checking the sidewall on the existing tire or the factory door-jamb placard is the fastest way to confirm what belongs on your specific Acura.

On a 2024 Acura Trucks tire, 255/45R20 is a metric radial size. The 255 is the section width in millimeters, 45 is the aspect ratio, meaning the sidewall height is 45 percent of the section width, the R identifies radial construction, and 20 is the wheel diameter in inches. Within the 2024 Acura Trucks range, this size applies to the RDX.

Understanding that code helps separate true fitment from tires that only look close on paper. A 255/45R20 will mount on a 20-inch wheel, but it is still different from other 20-inch Acura sizes such as 255/50R20 or 265/50R20 because width and sidewall profile affect overall dimensions. Matching the complete code is more important than matching only the rim diameter.

No, 2024 Acura Trucks models do not use the same tire size. The MDX, RDX, and ZDX each have their own fitment set, and no single tire size is shared across all three models. Acura also used multiple wheel diameters within the same model line, so even two MDX vehicles or two RDX vehicles may not use the same size if they came with different wheel packages.

That makes model identification essential before moving into brand or tread-choice decisions. If you know only that you have a 2024 Acura but have not confirmed whether it is an MDX, RDX, or ZDX, you are still one step short of the correct tire. Once the model and wheel size are confirmed, the tire search becomes much more straightforward.

Within the 2024 Acura Trucks fitments represented here, sidewall style variation appears in 255/45R20 for the RDX. That size is available in both Blackwall and RWL form, with Blackwall choices from BFGoodrich and Nitto and an RWL version from Pro-Trac. The other Acura sizes shown here do not have sidewall-style variety attached to them on this page.

For a modern Acura SUV, Blackwall is the more understated factory-style look most owners expect, while an RWL tire adds a more overt performance visual. The choice does not change the need to stay with the correct 255/45R20 size for the wheel. If appearance matters as much as fitment, sidewall style is worth deciding before narrowing down to a specific tire line.

The brand coverage shown here for 2024 Acura Trucks appears in 255/45R20, where BFGoodrich, Nitto, and Pro-Trac all offer tires. BFGoodrich appears with more than one product in that size, while Nitto and Pro-Trac each add a distinct alternative. All of those products are radial tires built for 20-inch wheel applications on the RDX.

Brand choice matters most after the size is settled, because 2024 Acura Trucks fitment is heavily model-specific. An RDX owner using 255/45R20 has the broadest brand selection on this page, while the other Acura sizes here call first for exact size confirmation. Once that is done, you can compare sidewall appearance, load capacity where shown, and the intended character of each tire line.

For 2024 Acura Trucks vehicles that use 255/45R20, BFGoodrich and Nitto both offer W-rated radial tires with a 168 mph speed ceiling, but the products are not identical. BFGoodrich appears in g-Force Comp 2 AS and g-Force Sport Comp 2 form, each on an 8.0- to 9.5-inch rim-width range, with one BFGoodrich entry carrying a max load figure of 1,819 pounds at 51 psi. The Nitto NT555 G2 in the same size is also W-rated and carries an XL marking.

That comparison is useful for an RDX owner who wants more than a simple brand name difference. BFGoodrich gives a clearer published rim-width range in this size, while Nitto adds an extra-load construction marking that some buyers prefer for modern SUV applications. The practical next step is to match the tire to how your RDX is used, then confirm wheel width and the exact sidewall marking before purchase.

Rim-width guidance appears here for one 2024 Acura Trucks size: 255/45R20. In that size, BFGoodrich specifies an 8.0- to 9.5-inch rim-width range. The other Acura sizes on this page do not carry a published rim-width range here, so the best approach is to verify the wheel specification already on the vehicle when working outside the 255/45R20 fitment.

Rim width matters because the same wheel diameter does not guarantee the tire is suitable for the wheel. A 20-inch wheel can still be too narrow or too wide for a given tire’s intended profile. If your 2024 Acura Trucks vehicle uses 255/45R20, the 8.0- to 9.5-inch range gives you a concrete benchmark; otherwise, confirm the wheel specs before changing tire sizes.

The 2024 Acura Trucks products shown here are modern radial tires without tube-type markings. The 255/45R20 options use contemporary metric radial sizing and include W-rated and XL-marked products, which align with modern tubeless passenger and SUV tire practice. Nothing in these Acura fitments points toward antique-style tube-type construction.

That said, wheel condition still matters on a modern SUV. If a wheel has been repaired, replaced, or refinished, it is worth checking bead-seat condition and valve stem condition at the same time the new tires are installed. For most buyers, the key takeaway is simple: confirm the exact size first, then make sure the wheels remain suitable for modern tubeless radial service.

No, the original wheels on 2024 Acura Trucks vehicles are tied to the specific tire size and rim diameter the vehicle was equipped with. MDX fitments span 19, 20, and 21 inches, RDX fitments span 19 and 20 inches, and ZDX fitments span 20 and 22 inches. A tire designed for one of those wheel diameters cannot be mounted correctly on a wheel of another diameter.

That means wheel reuse is possible only when the tire size matches the wheel diameter and the wheel width is appropriate for that tire. Even within one model line, moving from a 19-inch fitment to a 20-inch or 21-inch fitment requires a corresponding wheel change. Owners considering a change should treat diameter first and wheel width second, rather than assuming all factory Acura wheels interchange.

A 2024 Acura Trucks vehicle should be stored out of direct sunlight and away from ozone-producing equipment such as electric motors, welders, battery chargers, and air compressors. Keep the tires clean and dry, maintain inflation pressure close to normal operating levels, and move the vehicle periodically so the same tread section is not carrying the load for months at a time. Modern radials handle storage better than older bias-ply tires, but they still age when exposed to heat, UV, and long periods of static load.

If the SUV will sit for an extended season, many owners use tire cradles or place the vehicle on stands to reduce flat-spotting and relieve weight from the contact patch. A cool, enclosed garage is much better than outdoor storage, especially for larger wheel-and-tire packages with shorter sidewalls. Good storage habits preserve both appearance and long-term service life.

On a 2024 Acura Trucks vehicle, tire life should be judged by age and condition as much as by tread depth. A practical collector and enthusiast rule is to begin evaluating tires carefully at around five to seven years of age and to treat the ten-year mark as a serious replacement threshold regardless of mileage. The DOT date code on the sidewall is the best way to confirm the tire’s manufacturing age.

That matters because many newer luxury SUVs accumulate modest annual mileage yet still experience age-related hardening, cracking, or reduced wet-weather confidence. A tire with good-looking tread can still be too old for dependable service. For any 2024 Acura Trucks vehicle, age, visible condition, and how the vehicle is used should all be weighed together rather than relying on miles alone.

Tires on a 2024 Acura Trucks vehicle should be inspected before every drive and again before any extended highway trip. Check inflation, visible cuts, bulges, sidewall cracking, irregular tread wear, and any embedded debris. Because these Acura applications use modern radial SUV sizes, uneven wear can also point to alignment or suspension issues that deserve attention before the next long outing.

A quick walkaround catches problems early, especially on vehicles with larger-diameter wheels and lower-profile tires where impact damage can be easier to miss from the driver’s seat. Monthly pressure checks are also worthwhile even if the vehicle is not driven often. If the spare is part of your travel plan, inspect that tire as carefully as the four on the ground.

Yes, the 2024 Acura Trucks tires shown here are modern radial SUV and performance-oriented fitments, and the 255/45R20 products carry W speed ratings with a 168 mph ceiling. That far exceeds normal U.S. highway speeds, so in everyday driving the condition, age, inflation, and proper fitment of the tire matter more than the raw speed symbol alone. The other Acura sizes here are also modern radial fitments intended for contemporary road use when correctly matched to the vehicle.

Highway safety still depends on more than the sidewall code. Alignment, brake condition, suspension health, and correct inflation all influence how a modern Acura SUV behaves at speed. If the tire size matches the vehicle, the tires are in sound condition, and the rest of the SUV is properly maintained, normal highway driving is well within the expected use case.

Inflation pressure for a 2024 Acura Trucks vehicle should follow the factory vehicle placard first, because Acura sets pressure by model, tire size, and load expectations. One 255/45R20 BFGoodrich product here carries a max load figure of 1,819 pounds at 51 psi, but that is the tire’s maximum rated pressure for that tire, not a blanket operating recommendation for every Acura application or every tire size in the lineup.

The best practice is to use the Acura placard or owner’s manual for day-to-day inflation and to compare that with the specific tire’s sidewall information so the application stays within the tire’s rating. Do not transfer a pressure figure from one Acura size to another just because the wheel diameter is similar. Size, load rating, and vehicle calibration all matter.

Before a longer drive in a 2024 Acura Trucks vehicle, inspect each tire for proper inflation, tread depth, punctures, cuts, bulges, and any visible sidewall damage. Pay special attention to any uneven wear pattern, since that can signal alignment problems that may become more noticeable on the highway. If the vehicle has not been driven recently, check the spare as well and make sure the valve stems and wheel surfaces are in good condition.

That tire check should be part of a broader pre-trip routine on any modern SUV. Brakes, fluid levels, battery condition, and suspension health all contribute to a confident long-distance drive, especially on vehicles with larger wheel packages and lower-profile tires. Catching a weak tire, low pressure, or damaged sidewall at home is far better than discovering it after the trip has started.
