The 2023 Acura Trucks RDX blends luxury crossover comfort with the sharper road manners that have helped the model stand apart in Acura’s modern lineup. For many owners, it fills two roles at once: a daily-driven premium SUV and a vehicle whose stance and wheel package still matter visually. Tire fitment depends on sub-model, with 235/55R19 and 255/45R20 radial sizes both used on this exact RDX. That creates a meaningful choice not just in size, but in appearance and tire character, especially where blackwall, raised white letter, and redline options are available in the 20-inch fitment. The right selection starts with confirming the trim and wheel diameter already on the vehicle.
Which Tire Size Is Right for The 2023 Acura Trucks RDX
The 2023 Acura Trucks RDX uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel package. Both are radial metric sizes, but they mount on different rim diameters, so confirming whether the vehicle has 19-inch or 20-inch wheels is the first step before comparing tread design, sidewall style, or brand choices.
The 235/55R19 size combines a 235-millimeter section width with a 55-series profile, radial construction, and a 19-inch rim. For the 2023 Acura Trucks RDX, this size applies to several sub-models that use the 19-inch wheel setup rather than the larger 20-inch package. Its role in the lineup is straightforward: it is the correct primary fitment for those trims, not an alternate sizing experiment for 20-inch wheels. Choosing this size starts with verifying the actual wheel diameter on the vehicle, especially if wheels have ever been changed after delivery.
Tire fitment on the 2023 Acura Trucks RDX varies by sub-model, and the split follows the vehicle’s 19-inch and 20-inch wheel packages. Checking the exact trim matters because both primary sizes are radial, but they are not meant for the same rim diameter.

2023 Acura Trucks RDX A-Spec
The 2023 Acura Trucks RDX A-Spec uses the 255/45R20 radial fitment. Tire selection here centers on confirming the 20-inch wheel setup and then comparing available brand, series, and sidewall treatments that suit the vehicle’s more assertive visual package.
The 2023 Acura Trucks RDX Base uses the 235/55R19 radial size. The key step is staying with the 19-inch fitment and verifying that the vehicle still carries its intended wheel diameter before considering any replacement tire.
The 2023 Acura Trucks RDX SH-AWD uses the 235/55R19 radial fitment. That keeps tire selection straightforward, with the main focus on matching the 19-inch wheel setup and checking the current wheel and suspension configuration if the vehicle has been modified.
The 2023 Acura Trucks RDX SH-AWD A-Spec uses the 255/45R20 radial size. Choosing tires for this sub-model means confirming the 20-inch wheels first, then comparing available options by series and sidewall presentation rather than looking at 19-inch fitments.
The 2023 Acura Trucks RDX SH-AWD Advance Pkg. uses the 235/55R19 radial size. Replacement tire selection should stay focused on the 19-inch wheel package and on verifying that no aftermarket wheel change has altered the vehicle’s fitment needs.

Tire Size & Fitment
What tire size fits a 2023 Acura Trucks RDX?
The 2023 Acura Trucks RDX uses either 235/55R19 or 255/45R20, depending on sub-model. Both are radial metric tire sizes, but they are tied to different wheel diameters, so they are not the same fitment choice presented in two different ways.
The most important step is identifying the exact trim and confirming whether the vehicle has 19-inch or 20-inch wheels. Base, Tech, SH-AWD, SH-AWD Tech Pkg., and SH-AWD Advance Pkg. use 235/55R19, while A-Spec, SH-AWD A-Spec, and SH-AWD PMC Edition use 255/45R20.
What size rim does a 2023 Acura Trucks RDX use?
A 2023 Acura Trucks RDX uses either a 19-inch or 20-inch rim, depending on sub-model. The 235/55R19 fitment uses a 19-inch rim, while the 255/45R20 fitment uses a 20-inch rim.
Rim diameter should be confirmed before a replacement tire is chosen because these two RDX fitments are built around different wheel sizes. Looking only at overall tire appearance can be misleading, especially if the vehicle has aftermarket wheels or if a previous owner changed the original wheel package.
Why does the 2023 Acura Trucks RDX have more than one tire size?
The 2023 Acura Trucks RDX has more than one tire size because different sub-models use different wheel packages. Some trims use 235/55R19 on 19-inch wheels, while A-Spec-oriented versions and the SH-AWD PMC Edition use 255/45R20 on 20-inch wheels.
That means tire selection starts with trim identification rather than brand preference. Once the sub-model and wheel diameter are confirmed, the decision becomes much simpler because the buyer can compare only the tires built for that exact size instead of trying to treat the two fitments as interchangeable.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2023 Acura Trucks RDX?
A 255/45R20 tire for a 2023 Acura Trucks RDX should first match the vehicle’s actual 20-inch wheel setup. After that, the meaningful differences are brand, tire series, sidewall style, and any stated rim-width or load details that help separate one product from another.
This fitment has options from BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline presentations available. That gives owners room to choose between a more understated modern look and a stronger visual statement while still staying within the correct primary size for the 20-inch RDX setup.
What sidewall styles are available for 2023 Acura Trucks RDX tires?
For the 255/45R20 fitment used on certain 2023 Acura Trucks RDX sub-models, available sidewall styles include Blackwall, RWL, and Redline. Those choices create a noticeably different visual effect even when the tire size remains the same.
Blackwall gives the cleanest contemporary appearance, while RWL adds a more performance-oriented raised white letter look. Redline offers a distinct accent that can change the vehicle’s presentation without changing wheel diameter or primary fitment, so it is worth considering if style matters as much as simple replacement.
What brands offer tires for the 2023 Acura Trucks RDX?
The 255/45R20 fitment for the 2023 Acura Trucks RDX is available from BFGoodrich, Nitto, and Pro-Trac. Those brands cover several tire series, including g-Force Comp 2 AS, g-Force Sport Comp 2, NT555 G2, and Street Pro III.
Brand alone should not be the only deciding factor. It helps to compare the tire series, sidewall treatment, and any wheel-width or load information that appears with each option, then match those details to how the RDX is used and the look the owner wants to maintain.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Acura Trucks RDX?
A period-style approach on a 2023 Acura Trucks RDX is less about restoration in the vintage sense and more about preserving the character of the trim’s original wheel package. The starting point is using the correct primary size for the sub-model, either 235/55R19 or 255/45R20.
Appearance choices become more noticeable on the 20-inch fitment, where blackwall, raised white letter, and redline options are available. Keeping the correct wheel diameter and size matters more than chasing a different look with the wrong fitment, especially on a modern Acura where stance and proportion are closely tied to wheel package.
How does tire construction affect the appearance of a restored 2023 Acura Trucks RDX?
Tire construction is straightforward on the 2023 Acura Trucks RDX because the primary fitments are radial. That means the appearance decision is not bias-ply versus radial, but rather how the chosen radial tire’s sidewall style and series complement the trim and wheel design.
On a modern vehicle like the RDX, visual differences usually come from the sidewall treatment more than from construction type. A blackwall keeps the presentation subtle, while raised white letters or a redline can make the 20-inch setup look more expressive without stepping outside the vehicle’s correct basic fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Acura Trucks RDX?
Yes, modifications can affect tire fitment on a 2023 Acura Trucks RDX. Wheel changes, altered offsets, suspension lowering, spring changes, or body modifications can all change the clearances that the original 235/55R19 or 255/45R20 fitment was meant to work within.
That is why the actual wheel diameter and current setup should be checked before replacing tires, especially on a used RDX. Even if the size on the sidewall looks familiar, a non-original wheel package can change how the tire sits in the wheel opening and how it behaves at full steering lock.
What should I inspect before driving a 2023 Acura Trucks RDX on new tires?
Before driving a 2023 Acura Trucks RDX on new tires, inspect wheel condition, valve stems, inflation pressure, and the general condition of suspension and steering components. It also helps to confirm that the installed tire size matches the vehicle’s sub-model and the wheel diameter already on the RDX.
A short initial road check is worthwhile to make sure there is no rubbing, vibration, or clearance issue during turning and normal suspension movement. Rechecking pressure after the first drives is a smart habit as well, particularly if the vehicle has recently changed wheels or had alignment-related work.
What should I check before a longer drive in a 2023 Acura Trucks RDX?
Before a longer drive in a 2023 Acura Trucks RDX, check inflation pressure, tread condition, uneven wear, cuts, punctures, and any visible sidewall damage. The tire size should also be confirmed against the vehicle’s trim and wheel package so the RDX is traveling on the correct 19-inch or 20-inch fitment.
Longer trips put more emphasis on stability and heat management, so it is worth checking for slow air loss and making sure the tires are wearing evenly across the tread. A quick look at wheel hardware, alignment behavior, and full-lock clearance can prevent small fitment issues from becoming trip-interrupting problems.
