The 2024 Acura Trucks RDX sits in the modern luxury crossover category, combining Acura’s sport-focused character with everyday usability and all-weather confidence. For buyers who know this exact RDX, the tire decision is less about vintage-style construction and more about matching the correct wheel and trim-specific fitment. This model uses radial tires in either 235/55R19 or 255/45R20 depending on sub-model. That creates a meaningful choice between 19-inch and 20-inch applications, with available products ranging from blackwall performance-oriented designs to raised white letter and redline options in the 20-inch size. Before choosing, confirm the exact sub-model and wheel setup on the vehicle.
Which Tire Size Is Right for The 2024 Acura Trucks RDX
The 2024 Acura Trucks RDX uses two primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Both are radial metric sizes, but one fits a 19-inch wheel and the other fits a 20-inch wheel, so confirming the trim and the actual wheels on the vehicle is the first step before comparing brands, sidewall style, or tire series.
Fit(s): SH-AWD, SH-AWD Advance Pkg., and SH-AWD Tech Pkg.
Construction: Radial|Rim: 19 in
235/55R19 is a metric radial size in which 235 identifies the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2024 Acura Trucks RDX, this size serves the 19-inch wheel applications and keeps the fitment question focused on the correct trim and wheel package rather than construction type. Its listed dimensions make it a distinct fitment from the 20-inch option, even though overall diameter remains close. Choose this size only after confirming the vehicle is equipped for the 19-inch setup.
255/45R20 is a metric radial size with a 255-millimeter nominal section width, a 45-series profile, radial construction, and a 20-inch rim diameter. On the 2024 Acura Trucks RDX, this size belongs to the 20-inch wheel applications and carries the broader visible product variety, including BFGoodrich, Nitto, and Pro-Trac options. Available sidewall treatments include blackwall, raised white letter, and redline, with tire series such as g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Street Pro III. This is the size to evaluate when the vehicle has the larger factory-style wheel fitment.
Tire fitment on the 2024 Acura Trucks RDX varies by sub-model, so identifying the exact trim matters before choosing a tire. The main divide is between 19-inch and 20-inch wheel applications, making wheel confirmation just as important as the sub-model name.

Tire questions for the 2024 Acura Trucks RDX usually come down to trim-specific sizing, 19-inch versus 20-inch wheel fitment, and how to compare the available 255/45R20 product choices. The FAQs below focus on those practical decisions, along with maintenance and road-use checks.
Tire Size & Fitment
What tire size fits a 2024 Acura Trucks RDX?
The 2024 Acura Trucks RDX uses two tire sizes: 235/55R19 and 255/45R20. The correct size depends on the exact sub-model, with SH-AWD, SH-AWD Advance Pkg., and SH-AWD Tech Pkg. using 235/55R19, while SH-AWD A-Spec and SH-AWD A-Spec Advance use 255/45R20.
That means the first step is identifying the trim and confirming the wheel diameter currently on the vehicle. Since the RDX uses both 19-inch and 20-inch fitments, a buyer should not choose by year and model alone if the vehicle may have had wheel changes or package-related differences.
What size rim does a 2024 Acura Trucks RDX use?
A 2024 Acura Trucks RDX uses either a 19-inch or 20-inch rim, depending on sub-model. The 235/55R19 fitment uses a 19-inch wheel, and the 255/45R20 fitment uses a 20-inch wheel.
Rim diameter is the critical fitment checkpoint because a 19-inch tire and a 20-inch tire are not interchangeable. Looking at the sidewall on the current tires or measuring the wheel setup on the vehicle is the safest way to confirm what belongs on that specific RDX before comparing available tires.
Do all 2024 Acura Trucks RDX sub-models use the same tire size?
No. The 2024 Acura Trucks RDX has split fitment across its covered sub-models. SH-AWD, SH-AWD Advance Pkg., and SH-AWD Tech Pkg. use 235/55R19, while SH-AWD A-Spec and SH-AWD A-Spec Advance use 255/45R20.
That size split matters because it changes both wheel diameter and the range of tire choices available. A buyer shopping for an A-Spec model will be looking at 20-inch products, while a non-A-Spec 19-inch application needs the smaller wheel fitment confirmed before any decision about brand or style is made.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 Acura Trucks RDX?
Start with the exact tire size and wheel diameter used on the vehicle, since the 2024 Acura Trucks RDX can require either 235/55R19 or 255/45R20. Construction is straightforward because both primary fitments are radial, so the key variables become correct size, wheel compatibility, and the type of tire presentation you want.
For a 20-inch RDX, product selection also includes differences in brand, tire series, sidewall style, weight, and in some cases rim-width range. Matching those details to the vehicle’s actual wheels and intended use will help narrow the choice more effectively than comparing appearance alone.
What sidewall styles are available for 2024 Acura Trucks RDX tires?
Among the available 255/45R20 products for the 2024 Acura Trucks RDX, sidewall styles include blackwall, raised white letter, and redline. Those choices appear within the 20-inch fitment, giving buyers a visible appearance decision in addition to the basic size and brand choice.
Sidewall style does not change the need to match the correct tire size and wheel diameter. Once that fitment is confirmed, the sidewall treatment becomes a styling decision, whether the goal is a cleaner modern blackwall look or something with more visual character such as raised white lettering or a redline accent.
What brands offer tires for the 2024 Acura Trucks RDX?
The available 255/45R20 tire options for the 2024 Acura Trucks RDX include BFGoodrich, Nitto, and Pro-Trac. Those products span several tire series, including g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Street Pro III.
Brand alone should not make the decision. A more useful comparison is to look at which series, sidewall style, and wheel-width compatibility best match the vehicle’s setup and the look you want, then verify the chosen tire belongs to the correct 20-inch application on that specific RDX.
Restoration & Appearance
How important is correct tire fitment on a 2024 Acura Trucks RDX?
Correct tire fitment matters because the 2024 Acura Trucks RDX uses two different size and wheel combinations across its sub-model range. A 235/55R19 tire belongs to a 19-inch application, while a 255/45R20 belongs to a 20-inch application, so appearance choices should always come after size confirmation.
Even on a newer vehicle, the wrong wheel diameter or an incorrect replacement size can affect the overall look and how the tire sits in the wheel opening. Buyers considering a more distinctive sidewall treatment should first make sure the trim level and actual wheel setup match the intended tire fitment.
Which sidewall style suits a 2024 Acura Trucks RDX?
That depends on the look you want from a 20-inch RDX application. Blackwall gives the cleanest modern presentation, while raised white letter and redline add more visual emphasis and create a stronger custom or enthusiast-style appearance.
The practical point is to separate style from fitment. Sidewall treatment should be chosen only after confirming that the vehicle uses the 255/45R20 setup, because the visible design choice does not override size, wheel diameter, or compatibility with the actual wheels installed on the RDX.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Acura Trucks RDX?
Yes. Wheel changes, suspension lowering, altered offsets, or non-original wheel widths can all affect tire fitment on a 2024 Acura Trucks RDX. That matters even more on a model that already uses both 19-inch and 20-inch factory-style applications across different sub-models.
Any RDX with aftermarket wheels should have its actual diameter and width checked before replacement tires are chosen. Clearance at the fenders and during steering travel also deserves attention, especially when a vehicle has been modified from its original wheel and suspension configuration.
What should I inspect before driving a 2024 Acura Trucks RDX on new tires?
Check that the tires match the correct size for the vehicle, are mounted on the proper wheel diameter, and show no visible issues such as cuts, bulges, bead damage, or air loss after installation. Tire pressure should also be set correctly before the vehicle returns to regular road use.
A quick visual inspection around the wheel wells is worthwhile as well. Look for adequate clearance, confirm that the tires do not contact suspension or body components, and recheck pressures after the first drives so the new set starts life on the RDX in stable, properly maintained condition.
How often should tires on a 2024 Acura Trucks RDX be inspected?
Tires on a 2024 Acura Trucks RDX should be inspected regularly rather than only when replacement time arrives. Pressure, tread wear, sidewall condition, and any sign of puncture damage or irregular wear pattern are the main things to watch during routine ownership.
Regular inspection is especially useful when the vehicle sees changing seasonal use, rough pavement, or long highway trips. Catching a pressure issue or wear problem early can also help confirm that the tires, wheels, and alignment are working together properly on the specific 19-inch or 20-inch setup.
