2023 Acura Trucks Tire Fitment Guide

2023 Acura Trucks vehicles use five tire sizes across two models. The MDX uses 255/55R19, 255/50R20, and 275/40R21, while the RDX uses 235/55R19 and 255/45R20. Those sizes do not interchange across the whole 2023 Acura Trucks range, and they mount on 19-, 20-, or 21-inch wheels depending on the model and configuration. For the 255/45R20 size, approved rim width coverage runs from 8.0 to 9.5 inches on the products available in that fitment.

The practical takeaway is that year and make are only the starting point. You need to identify the model first, then confirm the wheel diameter already on the vehicle before choosing a tire. If you are replacing one tire or one axle pair rather than the whole set, verify the exact sidewall code on the vehicle now, since MDX and RDX fitments are close in overall type but not the same size.

On a 2023 Acura Trucks tire, 255/45R20 means the tire is 255 millimeters wide, the sidewall height is 45 percent of that width, the R indicates radial construction, and the tire mounts on a 20-inch wheel. In the 2023 Acura Trucks range, that exact size belongs to the RDX rather than the MDX. Products in this size include W-rated versions, which carry a 168 mph speed ceiling.

That code matters because a 20-inch wheel tire cannot be substituted onto a 19-inch or 21-inch wheel, even when the overall vehicle family is the same. It also helps you compare products within the same fitment, since sidewall style and load rating can vary even when the size code matches. For an RDX owner, the sidewall marking is the quickest way to confirm whether 255/45R20 is the correct replacement path.

No, 2023 Acura Trucks models do not use the same tire size. The MDX and RDX each have their own fitments, and even within the MDX there are three different sizes tied to different wheel diameters. The RDX splits between 235/55R19 and 255/45R20, while the MDX uses 255/55R19, 255/50R20, or 275/40R21.

That means model identification is the first checkpoint before looking at brands or tread designs. If the badge says MDX, you still need to confirm whether the vehicle has 19-, 20-, or 21-inch wheels. If it is an RDX, the choice narrows to 19- or 20-inch fitment. Matching the size already fitted to the wheel is more important than assuming all Acura crossovers from the same year share one replacement tire.

Sidewall style variety appears within the 255/45R20 fitment used on the 2023 Acura Trucks RDX. That size is available in both Blackwall and RWL form, with BFGoodrich and Nitto options in Blackwall and a Pro-Trac option in raised white letters. All of those choices remain radial tires in the same basic size category, so the visual difference is in the sidewall presentation rather than the fitment code itself.

For a late-model Acura crossover, Blackwall is the more factory-like look for most owners, especially if the goal is to keep the appearance clean and contemporary. RWL adds a more overt performance styling cue and may appeal to buyers who want the sidewall to stand out. The best choice comes down to how original or how personalized you want the vehicle to appear once the correct size is confirmed.

Within the current fitments covered here, 2023 Acura Trucks vehicles have 255/45R20 availability from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both g-Force Comp 2 AS and g-Force Sport Comp 2 forms, Nitto appears in the NT555 G2 line, and Pro-Trac appears in the Street Pro III line. All of those products are radial tires sized for the RDX 20-inch application.

Brand choice matters less than getting the exact size and wheel diameter correct first. Once that is settled, buyers can compare sidewall style, load capacity, and overall tire character within the same fitment. If your 2023 Acura Trucks vehicle uses a different size than 255/45R20, the next step is to stay within that exact sidewall code rather than assuming every brand or series carries over to the whole model range.

For the 2023 Acura Trucks 255/45R20 fitment, BFGoodrich offers both the g-Force Comp 2 AS and the g-Force Sport Comp 2. Both are radial Blackwall tires in the same 255/45ZR20 size, both fit 20-inch wheels, both cover an 8.0 to 9.5 inch rim width range, and both weigh 32 pounds. The g-Force Sport Comp 2 carries a stated maximum load of 1,819 pounds at 51 psi in this size.

Because the dimensions and wheel fitment overlap so closely, the choice comes down to the specific series character you prefer within the same size category rather than a major fitment difference. Buyers comparing these two should verify the exact sidewall marking, load information, and intended use before deciding. That approach keeps the comparison focused on product details inside the correct RDX 20-inch fitment.

Rim width guidance is available for the 2023 Acura Trucks 255/45R20 fitment. In that size, the tire products covered here fit wheels from 8.0 to 9.5 inches wide and mount on a 20-inch rim diameter. That range applies to the BFGoodrich products in this fitment and provides a useful benchmark when checking an RDX wheel before installation.

Rim width matters because even the correct diameter and size code can perform poorly if the wheel is too narrow or too wide for the tire. When replacing aftermarket tires or wheels, confirm both the sidewall size and the actual wheel width stamped or measured on the vehicle. That is especially important on modern crossovers, where appearance packages and wheel upgrades can change the fitment without changing the basic model name.

The available 2023 Acura Trucks 255/45R20 products are modern radial tires without tube-type markings such as TT, so they fall into the tubeless category used on contemporary wheels. No tube requirement appears in that fitment. The other 2023 Acura Trucks sizes on this page are also modern radial fitments, which aligns with tubeless construction on factory late-model crossover wheels.

Even so, the wheel itself still needs to be in proper condition, with a sound bead seat and a healthy valve stem or service kit. If an Acura has aftermarket wheels, confirm that the wheel is intended for tubeless radial use and inspect for corrosion, curb damage, or prior repairs before mounting new tires. A clean seal at the rim matters just as much as the tire choice itself.

A 2023 Acura Trucks vehicle should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that age rubber. If the vehicle sits for long periods, move it periodically so one section of the tread does not carry the load continuously. Keeping the tires off wet concrete and away from petroleum products also helps preserve the casing and sidewall surface.

For seasonal or low-mileage use, the goal is to prevent flat spotting, pressure loss, and sidewall weathering before they become visible problems. Long-term storage on stands can be helpful if done correctly, but many owners do just as well by maintaining pressure and rolling the vehicle occasionally. A quick pressure check before and after storage is a simple habit that protects both ride quality and tire life.

On a 2023 Acura Trucks vehicle, tire age is usually a more important checkpoint than mileage alone, especially if the vehicle is driven modestly. A good rule is to begin careful evaluation around five to seven years from the tire's manufacturing date and to treat about ten years as the outer limit for continued service consideration. The DOT date code on the sidewall is the reference point for that timeline.

Luxury crossovers often accumulate miles unevenly, with plenty of short trips, parking time, and occasional highway use, so a tire can age out before the tread wears out. Regular inspection for cracking, hardening, bulges, and persistent air loss matters just as much as tread depth. If the age is climbing and the vehicle is used for family travel or longer drives, replacement becomes a wise preventive decision rather than a mileage question.

Tires on a 2023 Acura Trucks vehicle should be inspected before every drive in a quick walk-around and given a closer check before any extended highway trip. Look for cuts, bulges, uneven wear, punctures, sidewall cracking, and any change in pressure retention. On modern tubeless radial fitments, include the valve stems and valve caps in that inspection because a slow leak often starts there rather than in the tread itself.

That routine is especially important when the vehicle is not driven daily, since problems can develop while parked. A tire that looked fine a month ago may have lost pressure, picked up a nail, or developed visible curb damage since the last outing. Catching those issues early helps protect the tire, the wheel, and the vehicle's ride and handling before a small problem becomes an inconvenient roadside stop.

2023 Acura Trucks tires in the fitments covered here are modern radial designs, which are well suited to normal highway driving when the tire is the correct size, properly inflated, and in sound condition. Within the 255/45R20 fitment, W-rated products carry a 168 mph speed ceiling, which is well beyond typical public-road use. On a late-model Acura crossover, tire condition, inflation, alignment, and load management are far more relevant in real-world highway safety than the raw speed letter alone.

Safety still depends on the whole vehicle, not only the tire. Before sustained highway use, confirm that the tires match the wheel diameter, hold pressure correctly, and show no impact damage or irregular wear. If the vehicle has been modified with non-original wheels or lowered suspension, inspect for rubbing and clearance as well. A correctly matched radial in the proper size is the foundation for confident road use.

Inflation pressure for 2023 Acura Trucks tires should follow the vehicle placard or owner's manual first, because Acura sets pressure around the vehicle's weight balance, suspension tuning, and intended load. In the available 255/45R20 fitment, one BFGoodrich product carries a maximum load of 1,819 pounds at 51 psi, but that figure is the tire's rated maximum and should not be treated as the everyday operating pressure for every 2023 Acura Trucks application.

The practical approach is to start with the factory vehicle recommendation, then compare that with the tire maker's sidewall information to make sure you stay within the tire's limits. Do not transfer a pressure figure from one size to another, since the MDX and RDX use different tire dimensions and wheel diameters. Checking pressure cold, before driving, will give the most consistent and useful reading.

Before a longer drive in a 2023 Acura Trucks vehicle, inspect each tire for proper inflation, tread depth, cuts, bulges, sidewall cracking, punctures, and any sign of uneven wear that could point to alignment or suspension issues. Check the valve stems, confirm the spare is usable if the vehicle carries one, and look over the wheel for bends or curb damage. A late-model crossover should also have its TPMS functioning properly before leaving.

That tire inspection works best as part of a broader pre-trip routine that also includes brakes, fluids, lights, and wiper condition. If the vehicle has sat for a while, drive a short distance locally first and recheck pressures afterward. Catching a slow leak, a damaged sidewall, or a wheel issue at home is far easier than discovering it after the trip is underway.
