2022 Acura Trucks Tire Fitment Guide

2022 Acura Trucks vehicles use five sizes across two model lines. The MDX uses 255/55R19, 255/50R20, and 275/40R21, while the RDX uses 235/55R19 and 255/45R20. Those sizes span 19-, 20-, and 21-inch wheel diameters, so there is no single tire size that fits the full 2022 Acura Trucks range.

That makes model identification the first step, followed by wheel-diameter confirmation on the vehicle itself. If you are replacing tires on a used MDX or RDX, do not assume the current wheels are original to the vehicle. Checking the sidewall on the existing tire and confirming the wheel size before ordering is the simplest way to avoid crossing a 19-inch fitment with a 20- or 21-inch application.

On a 2022 Acura Trucks tire, 255/45R20 is a metric radial size. The 255 is the nominal section width in millimeters, 45 is the aspect ratio, the R confirms radial construction, and 20 is the wheel diameter in inches. Within this 2022 Acura Trucks range, that size applies to the RDX rather than the MDX.

Reading the code correctly matters because every part of it affects compatibility. A 255/45R20 tire may look close to another 20-inch size at a glance, but a different width or aspect ratio changes overall dimensions and intended fitment. If your RDX wears 20-inch wheels, confirm that the full sidewall code matches 255/45R20 before moving on to brand, sidewall style, or speed-rating preferences.

No, 2022 Acura Trucks models do not use the same tire size. The MDX and RDX each have their own fitment group, and even within the MDX there are multiple sizes tied to different wheel diameters. The overlap is only that both model lines use modern radial construction, not that they share one interchangeable tire size.

That means year and make alone are not enough for an accurate tire choice on a 2022 Acura Trucks vehicle. You need the model first, then the exact wheel package or the tire code currently on the vehicle. Once that is confirmed, the comparison becomes much more useful because you are evaluating tires that actually belong to your MDX or RDX rather than looking across the full Acura crossover lineup.

For 2022 Acura Trucks fitments with current product coverage, the 255/45R20 size is available with both Blackwall and RWL sidewall styles. BFGoodrich and Nitto options in this size use Blackwall construction, while Pro-Trac offers an RWL version. All of them are radial tires sized for the RDX 20-inch application.

The choice is mostly about appearance rather than basic fitment. A Blackwall look keeps the presentation clean and contemporary, which suits how many late-model luxury crossovers are typically finished, while an RWL tire adds a more assertive performance-style visual. If appearance matters to you, check the sidewall styling first before comparing any other feature, because that one detail changes the look of the vehicle from across the parking lot.

BFGoodrich, Nitto, and Pro-Trac all offer tires for 2022 Acura Trucks applications within the currently covered 255/45R20 size. BFGoodrich appears with both g-Force Comp 2 AS and g-Force Sport Comp 2 options, Nitto offers the NT555 G2, and Pro-Trac offers the Street Pro III. Each of those choices is built as a radial tire for the RDX 20-inch fitment.

Brand choice comes after you confirm that your MDX or RDX uses the size in question. Once the size is correct, comparing brands can help narrow the look and character you want, especially if you are choosing between a more understated Blackwall presentation and an RWL style. Keeping the comparison inside the exact size required for your vehicle is the best way to make the brand decision meaningful.

For 2022 Acura Trucks vehicles in 255/45R20, both BFGoodrich choices share radial construction, Blackwall styling, a 20-inch rim diameter, a 101W service description, and an 8.0- to 9.5-inch rim-width range. The recorded weight is 32 pounds for each. The g-Force Sport Comp 2 also carries a max load figure of 1819 pounds at 51 psi in this size.

Those similarities mean the comparison is less about basic fitment and more about choosing the specific series you prefer within the same overall dimensional package. Since both cover the same wheel-width range and speed rating, the better next step is to confirm which tire aligns with your intended road use and visual preference. On a 2022 Acura Trucks RDX, either one starts from the same core size and wheel-diameter compatibility.

Rim-width guidance is available for one 2022 Acura Trucks size here: 255/45R20 fits an 8.0- to 9.5-inch rim width. That size belongs to the RDX 20-inch application and appears across multiple radial products from BFGoodrich. The wheel diameter for that fitment remains 20 inches, but width still matters for proper tire support and shape.

If your RDX uses 255/45R20 tires, measure or verify the wheel width before finalizing a tire choice, especially if the vehicle has aftermarket wheels. A tire can match the rim diameter and still be poorly matched to the wheel width. Staying inside the published rim-width range helps maintain the tire’s intended profile and keeps the installation closer to how the tire was engineered to sit on the wheel.

The 2022 Acura Trucks products covered here are modern radial tires and do not carry tube-type markings in the available 255/45R20 examples. Their size markings use ZR-based radial notation without TT identification, which points buyers toward contemporary tubeless-style construction for that size. The other 2022 Acura Trucks sizes on this page are also radial applications.

Even so, the wheel itself still deserves attention. If a wheel has been repaired, modified, or replaced, confirm that it is suitable for the tire being installed and inspect the valve stem condition at the same time. On late-model crossover applications like the MDX and RDX, the tire choice usually begins as a straightforward modern radial replacement, but wheel condition remains part of a proper setup.

A 2022 Acura Trucks vehicle should be stored in a cool, dry place away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that can age rubber. Keep the tires clean, maintain proper inflation during storage, and move the vehicle periodically if it will sit for long stretches. Radial tires generally tolerate storage better than older bias-ply designs, but they still age when left stationary and underinflated.

The practical goal is to reduce heat, UV exposure, moisture, and prolonged static loading. If the vehicle will be parked for months rather than weeks, some owners use tire cradles or stands as part of a broader storage plan, but regular pressure checks matter more than accessories alone. Good storage habits help preserve ride quality, reduce flat-spotting risk, and make the tires a stronger starting point when the vehicle returns to regular use.

Tires on a 2022 Acura Trucks vehicle should be judged by age and condition as much as by tread depth. A sensible collector and low-mileage rule is to begin evaluating tires closely around five to seven years of service and to treat around ten years as a serious replacement point, even if the tread still looks usable. The DOT date code on the sidewall is the simplest way to determine tire age.

That approach matters because many premium crossovers accumulate miles unevenly: one owner may wear through tires quickly, while another may age them out long before the tread is gone. Heat cycles, climate, storage quality, and inflation habits all influence how long a tire remains trustworthy. If a 2022 Acura Trucks vehicle sees occasional use, age can become the deciding factor sooner than mileage would suggest.

Tires on a 2022 Acura Trucks vehicle deserve a quick inspection before every drive and a more thorough one before any longer trip. Look for cracking, punctures, bulges, uneven wear, and pressure loss, and check that the tread is wearing evenly across the contact patch. On a modern radial application, changes in handling or steering feel can also be an early sign that one tire needs closer attention.

Frequent inspection is especially useful on vehicles that alternate between daily use and longer parked periods. A tire can lose pressure or suffer sidewall damage without obvious symptoms until the next drive. Building a habit of checking pressure, tread, and sidewalls before road trips gives you time to correct a problem in the garage instead of discovering it after the vehicle is fully loaded and already out on the highway.

2022 Acura Trucks vehicles use modern radial tire sizes, and the covered 255/45R20 products carry W speed ratings, which correspond to a 168 mph ceiling where marked. That is well beyond normal U.S. highway speeds, so for everyday driving the tire’s published speed category is not the limiting factor in typical use. Condition, inflation, alignment, and the vehicle’s overall mechanical health matter more than chasing the highest rating available.

Highway safety starts with matching the exact size to the correct MDX or RDX application and then making sure all four tires are in sound condition. A late-model luxury crossover may be capable and stable at speed, but a damaged sidewall, improper inflation, or mismatched tire set can undermine that quickly. If you are preparing for sustained interstate use, focus first on age, wear consistency, and pressure rather than headline performance branding.

Inflation pressure on a 2022 Acura Trucks vehicle should follow the factory placard or owner’s manual for the specific model and wheel package. One 255/45R20 BFGoodrich application carries a max load figure of 1819 pounds at 51 psi, but that number is the tire’s rated maximum and should not automatically be used as the day-to-day vehicle setting. Tire pressure must stay tied to the vehicle application and the exact size in use.

That distinction is important because maximum sidewall pressure and recommended operating pressure serve different purposes. The sidewall figure supports the tire’s rated load capacity, while the vehicle manufacturer’s specification balances ride, handling, and wear for the MDX or RDX itself. Use the placard as your normal baseline, adjust only within manufacturer guidance, and recheck pressures when seasonal temperatures shift significantly.

Before a longer drive in a 2022 Acura Trucks vehicle, inspect each tire for cuts, bulges, cracking, punctures, and uneven wear, then confirm cold inflation pressure and tread condition. Check the spare as well, since an overlooked spare can become the weak link on an otherwise prepared vehicle. Because these are model-specific fitments, it also helps to confirm that all four road tires match in size and basic service type.

Tires are only one part of a longer-trip preparation, but they are the easiest place to catch trouble early. A quick walkaround should be followed by a broader check of brakes, fluids, lights, and suspension condition, especially if the vehicle has been parked for any length of time. On a modern Acura crossover, a careful pre-drive inspection usually prevents the most avoidable roadside issues before the trip even begins.
