The 2010 Acura Trucks RDX came to market as a compact luxury crossover that balanced everyday utility with a more driver-focused feel than many utility vehicles of its era. Its turbocharged, all-weather personality makes tire choice especially important, because the right fitment affects appearance, ride quality, and day-to-day confidence. This RDX uses a 235/55R18 radial tire, giving it a modern metric fitment on an 18-inch wheel. That makes the decision less about sorting through multiple original sizes and more about choosing the right tire within the correct size. For a stock vehicle, wheel condition, overall tire condition, and any suspension or wheel changes should be checked before replacement.
Which Tire Size Is Right for The 2010 Acura Trucks RDX
The 2010 Acura Trucks RDX uses one primary tire size: 235/55R18. It is a radial fitment on an 18-inch rim, and that same size is used across the covered RDX sub-models. The main decision is not which primary size fits, but which 235/55R18 tire best suits the vehicle's current wheel setup, intended road use, and overall condition.
A 235/55R18 size uses a 235-millimeter nominal section width, a 55-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2010 Acura Trucks RDX, this is the primary modern radial fitment, so the sizing format will be familiar to owners comparing current replacement tires. Because the vehicle stays within one size across its covered sub-models, selection typically comes down to choosing a tire that matches the wheel dimensions and the vehicle's intended use. It is also worth confirming the actual wheel setup if aftermarket wheels or suspension changes have been added over time.
Tire fitment is straightforward across the covered 2010 Acura Trucks RDX sub-models. Both use the same 235/55R18 radial size, so sub-model identification matters less than confirming the vehicle still has its correct 18-inch wheel setup.

2010 Acura Trucks RDX Base
The 2010 Acura Trucks RDX Base uses the same 235/55R18 radial tire size as the other covered RDX configuration. That keeps replacement selection centered on choosing the right tire within the correct size and verifying that the vehicle has not been altered with different wheels or suspension changes.
The 2010 Acura Trucks RDX SH-AWD also uses a 235/55R18 radial tire, so its primary fitment remains consistent with the Base model. Tire selection is mainly about staying with the correct size and confirming wheel condition, alignment, and clearance if the vehicle has been modified from stock.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
For the 2010 Acura Trucks RDX, the key questions center on the 235/55R18 tire size, 18-inch rim fitment, replacement selection, and the checks worth making before putting a crossover that may have seen wheel or suspension changes back on the road.
Tire Size & Fitment
What tire size fits a 2010 Acura Trucks RDX?
The 2010 Acura Trucks RDX uses a 235/55R18 tire size. This is a modern metric radial size, and it serves as the primary fitment for the covered RDX configurations, including Base and SH-AWD.
That means the first priority is matching the vehicle to a proper 235/55R18 tire on an 18-inch wheel rather than sorting through multiple factory sizes. A vehicle that still wears stock-size wheels is usually straightforward, but any aftermarket wheel change, lowered suspension, or prior replacement with a different size should be checked carefully before choosing tires.
What size rim does a 2010 Acura Trucks RDX use?
The 2010 Acura Trucks RDX uses an 18-inch rim with its 235/55R18 tire size. The final number in the size code, 18, refers to the wheel diameter the tire is built to mount on.
Rim diameter is only one part of the fitment picture, so it is still wise to confirm the actual wheel on the vehicle before replacement. Wheel width, offset, and any non-stock wheel package can affect how a 235/55R18 tire sits and clears, even when the diameter itself remains correct.
Do all 2010 Acura Trucks RDX sub-models use the same tire size?
Yes. The covered 2010 Acura Trucks RDX sub-models use the same 235/55R18 radial tire size. That includes both the Base model and the SH-AWD model.
Shared sizing makes replacement simpler because the main fitment question is usually the condition of the vehicle's current wheel and suspension setup rather than the trim level. It is still smart to inspect the wheels already on the RDX, since previous owners may have changed wheel size or tire profile even though the original fitment remains the same.
Choosing the Right Tire
What should I consider when choosing a 235/55R18 tire for a 2010 Acura Trucks RDX?
Start with the correct size and construction: 235/55R18 radial on an 18-inch wheel. From there, the important considerations are wheel compatibility, the condition of the suspension and alignment, and how the RDX is actually used, whether that means regular commuting, seasonal driving, or lower annual mileage.
A stock-height vehicle on stock wheels is usually the easiest place to begin, but older crossovers often pick up wheel swaps over time. It helps to inspect for uneven wear, verify the current wheel dimensions, and think about ride expectations before choosing a replacement, especially if the existing tires have been masking alignment or suspension issues.
How do I choose between available 235/55R18 tires for a 2010 Acura Trucks RDX?
The best way to compare 235/55R18 choices for a 2010 Acura Trucks RDX is to begin with proper fitment, then look at the tire's intended use and how closely it matches the vehicle's condition. A daily-driven RDX may call for a different emphasis than one that is used occasionally or stored part of the year.
It is also worth comparing the overall age and wear pattern of the other tires already on the vehicle if only part of the set is being replaced. Even within one correct size, ride quality, steering feel, and clearance can be affected by wheel condition, alignment, or suspension wear that should be addressed before installation.
What rim-fitment details should I compare when choosing 2010 Acura Trucks RDX tires?
For a 2010 Acura Trucks RDX, the key rim-fitment detail is that the tire size 235/55R18 belongs on an 18-inch wheel. Beyond diameter, the practical details are the actual wheel width and offset on the vehicle, especially if the RDX no longer uses its original wheel package.
Those measurements matter because a correct tire size can still present clearance or handling concerns on a mismatched wheel. Checking the wheels already on the vehicle, along with visible clearance at the strut, fender, and steering range, helps avoid choosing a tire based only on size code without confirming the full setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Acura Trucks RDX?
Yes. A 2010 Acura Trucks RDX may originally use a 235/55R18 tire, but wheel swaps, lowering, altered spring height, or suspension wear can change how that size fits and behaves. Even small changes in wheel offset or tire profile can affect clearance and overall stance.
That is why a modified RDX should be checked at full steering lock and under normal ride height before replacement tires are chosen. Looking closely at fender clearance, inner wheelhouse space, and signs of rubbing on the old tires can reveal whether the current setup still supports the stock-size fitment cleanly.
What should I inspect before driving a 2010 Acura Trucks RDX on new tires?
Before putting a 2010 Acura Trucks RDX back into regular use on new tires, inspect the wheels for damage, confirm proper inflation, and look over the suspension and steering components for looseness or wear. Alignment condition also matters, since a fresh set of tires can wear quickly if the chassis is already out of spec.
A close look at the vehicle's old tires can also be revealing. Uneven tread wear, cracking, bulges, or repeated air loss often point to issues that should be corrected before the new set sees road miles. That extra inspection helps the new 235/55R18 tires deliver a more stable and predictable result.
How often should tires on a 2010 Acura Trucks RDX be inspected?
Tires on a 2010 Acura Trucks RDX should be inspected regularly, not just when tread appears low. A visual check for uneven wear, sidewall cracking, punctures, bulges, and air loss is a good routine habit, especially on an older vehicle that may not accumulate miles evenly throughout the year.
Periodic inspection matters because age, storage conditions, and alignment can affect a tire long before it looks obviously worn out. Checking pressures when the tires are cold and watching for changes in steering feel, vibration, or road noise can help catch a problem early, before it turns into premature wear or a roadside issue.
