The 2010 Acura Trucks MDX sits in the era when luxury crossovers were expected to deliver everyday comfort, all-weather confidence, and a more athletic feel than traditional truck-based SUVs. Buyers often chose the MDX for exactly that balance, which makes getting the tire size right especially important. This model uses two primary radial fitments, 255/55R18 or 255/50R19, depending on the specific MDX configuration. That means the decision starts with confirming whether the vehicle is on its original 18-inch or 19-inch wheel setup, then comparing tire choices within the correct size. For a stock or restoration-minded example, keeping the proper size and wheel pairing is the foundation of proper fitment.
Which Tire Size Is Right for The 2010 Acura Trucks MDX
The 2010 Acura Trucks MDX uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. Both fitments are radial, but one is built around an 18-inch rim and the other around a 19-inch rim, so the first step is confirming the exact MDX trim and the wheels currently on the vehicle before comparing tire options.
A 255/55R18 tire uses a 255-millimeter section width, a 55-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2010 Acura Trucks MDX, this is one of the primary fitments and it supports the crossover's original balance of ride height and wheel size. Its overall diameter matches the 255/50R19 alternative, but the wheel diameter does not, so the two sizes are tied to different wheel setups. Choose this size when the vehicle is equipped with the correct 18-inch wheels and the trim level calls for this fitment.
A 255/50R19 tire keeps the same 255-millimeter nominal width as the 18-inch option, but uses a shorter 50-series sidewall on a 19-inch rim. For the 2010 Acura Trucks MDX, this size applies to a specific sub-model configuration rather than the full lineup. Its overall diameter is the same as the 255/55R18 fitment, yet wheel compatibility still depends on having the correct 19-inch rim. This is the size to evaluate when the MDX is equipped with the proper 19-inch wheels and has not been changed from its intended setup.
Tire fitment on the 2010 Acura Trucks MDX is not identical across all covered sub-models. Checking the exact trim matters because the MDX uses both 18-inch and 19-inch wheel-based tire sizes, and choosing between them starts with matching the vehicle's actual configuration.

2010 Acura Trucks MDX Base
The 2010 Acura Trucks MDX Base uses the 255/55R18 radial fitment. Tire selection for this sub-model starts with confirming that the vehicle still carries its intended 18-inch wheel setup, then comparing replacement tires within that size.
The 2010 Acura Trucks MDX w/Advance Pkg. uses the 255/50R19 radial size. That makes wheel confirmation especially important, since this trim is tied to a 19-inch fitment rather than the 18-inch setup used elsewhere in the MDX range.
The 2010 Acura Trucks MDX w/Technology Pkg. uses the 255/55R18 radial size, the same primary fitment used by the Base model. For tire replacement, the key step is staying with the correct 18-inch size unless the vehicle has been changed to a different wheel package.
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
Owners researching 2010 Acura Trucks MDX tires usually need to sort out the correct size by trim, confirm 18-inch versus 19-inch wheel fitment, and make sure the vehicle is still on the wheel setup it was meant to use.
Tire Size & Fitment
What tire size fits a 2010 Acura Trucks MDX?
The 2010 Acura Trucks MDX uses two tire sizes: 255/55R18 and 255/50R19. Both are radial fitments, but they do not apply across the entire model range. The Base model and the w/Technology Pkg. use 255/55R18, while the w/Advance Pkg. uses 255/50R19.
The practical difference is wheel diameter. A 255/55R18 tire belongs on an 18-inch rim, and a 255/50R19 tire belongs on a 19-inch rim. Before choosing tires, confirm the exact sub-model and check the wheels currently on the vehicle, especially if it was purchased used or has had wheel changes over time.
What size rim does a 2010 Acura Trucks MDX use?
A 2010 Acura Trucks MDX uses either an 18-inch or 19-inch rim, depending on the sub-model. The 255/55R18 fitment is built for an 18-inch wheel, and the 255/50R19 fitment is built for a 19-inch wheel. Both sizes are radial and share the same overall diameter, but the rim diameter is different.
That means tire shopping should start at the wheel, not just the tread size. Look at the tire sidewall already on the MDX and verify the wheel diameter before replacement. Matching the tire to the correct rim diameter is essential, even when the two sizes appear close in width and overall height.
Do all 2010 Acura Trucks MDX sub-models use the same tire size?
No. The 2010 Acura Trucks MDX does not use one tire size across every covered sub-model. The Base and w/Technology Pkg. models use 255/55R18, while the w/Advance Pkg. uses 255/50R19. Both are radial sizes, but they are tied to different wheel diameters.
That distinction matters because the wrong size can create an immediate mismatch with the wheel. Even though both tire sizes carry the same nominal width and overall diameter, the correct choice still depends on the trim and the actual wheel package on the vehicle. Confirm both before making a replacement decision.
Choosing the Right Tire
What should I consider when choosing a 255/55R18 tire for a 2010 Acura Trucks MDX?
Start by confirming that the 2010 Acura Trucks MDX is a Base or w/Technology Pkg. model, or that it is currently running the correct 18-inch wheel setup. A 255/55R18 tire uses radial construction and is one of the MDX's primary fitments, so size accuracy and proper wheel diameter come first.
After that, compare tires within the same size based on intended use, ride expectations, and the condition of the vehicle's suspension and alignment. A crossover like the MDX responds best when tire size, wheel diameter, and overall setup stay consistent, so avoid assuming that another size is suitable just because it looks similar.
What should I consider when choosing a 255/50R19 tire for a 2010 Acura Trucks MDX?
The first step is confirming that the 2010 Acura Trucks MDX is the w/Advance Pkg. configuration or that it is properly equipped with 19-inch wheels. The 255/50R19 size is a primary radial fitment for that setup, and it should be treated as a wheel-specific choice rather than a general MDX tire size.
Selection should then focus on staying within the correct size and making sure the vehicle has no wheel, suspension, or clearance changes that would affect fitment. Because this size is paired to a 19-inch rim, it is not interchangeable with the 18-inch fitment without confirming the full wheel and tire package.
How do I choose between the available tire sizes for a 2010 Acura Trucks MDX?
The correct choice is determined by the MDX sub-model and wheel diameter, not by personal preference alone. A 2010 Acura Trucks MDX uses either 255/55R18 or 255/50R19, and each size belongs to a specific wheel setup. Both are radial sizes and both share the same overall diameter, but they are not mounted on the same rim diameter.
That means the safest approach is to identify the trim level, then verify the wheels currently on the vehicle before shopping. If the MDX has aftermarket wheels or a changed package, use the actual wheel diameter and current setup as the starting point so the replacement tire matches the hardware on the vehicle.
Restoration & Appearance
Does correct tire fitment matter for a 2010 Acura Trucks MDX restoration?
Yes. Even on a modern luxury crossover, correct tire fitment plays a major role in preserving the intended stance, wheel-to-tire relationship, and overall presentation. The 2010 Acura Trucks MDX uses either 255/55R18 or 255/50R19 depending on trim, so restoration-minded work should begin with the proper size for the exact configuration.
Appearance is only part of the equation. Matching the right tire size to the right wheel diameter also helps preserve the vehicle's original fitment character and avoids obvious visual mismatches. For an especially accurate result, compare the vehicle's current wheels and trim details with marque-specific references before making a final tire choice.
Which tire should I choose for a period-style 2010 Acura Trucks MDX?
A period-style choice for a 2010 Acura Trucks MDX starts with using the tire size that belongs to the exact sub-model. That means 255/55R18 for the Base and w/Technology Pkg., or 255/50R19 for the w/Advance Pkg. Keeping the proper size and wheel pairing is the clearest way to maintain the vehicle's intended look.
Once the size is right, focus on a tire that suits how the MDX will be used and how original you want the vehicle to appear. A stock-wheel vehicle generally looks most cohesive when the replacement tire stays faithful to the original size format rather than shifting to a different diameter or improvised wheel package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Acura Trucks MDX?
Yes. Modifications can change tire fitment on a 2010 Acura Trucks MDX even when the original tire size is known. Aftermarket wheels, altered offsets, suspension changes, or lowering can all affect how a 255/55R18 or 255/50R19 tire sits in the wheel opening and how much clearance it has while turning or moving through suspension travel.
A modified MDX should be checked at the wheel rather than relying only on trim-based fitment. Confirm actual rim diameter, measure wheel width where necessary, and inspect steering and fender clearance before replacing tires. That extra step is especially important when the vehicle has been changed from its original 18-inch or 19-inch setup.
What should I inspect before driving a 2010 Acura Trucks MDX on new tires?
Before driving a 2010 Acura Trucks MDX on new tires, inspect wheel condition, valve stems, and basic suspension and steering components. Make sure the tire size matches the wheel diameter, then check for any signs of uneven wear that could point to alignment issues. Tire pressure should also be set correctly before road use.
A careful inspection helps the new tires perform as intended instead of masking another problem. Look for rubbing marks, damaged wheels, loose hardware, or components that could affect tracking and tire wear. Taking a short test drive and rechecking pressure afterward is a good way to confirm that the setup is behaving normally.
What should I check before a longer drive in a 2010 Acura Trucks MDX?
Before a longer drive, confirm that the 2010 Acura Trucks MDX is wearing the correct tire size for its trim and wheel package, either 255/55R18 or 255/50R19. Check inflation pressure, tread condition, and the sidewalls for cuts, bulges, or age-related cracking. Any tire that has been losing air should be addressed before the trip.
Longer drives put more heat and sustained load into the tire, so basic condition matters more than many occasional-use owners realize. It also helps to inspect the spare, verify lug hardware, and make sure no rubbing occurs at full steering lock. Those checks are especially worthwhile on an MDX that sees limited seasonal use.
