The 2016 Acura Trucks MDX sits in the modern luxury crossover segment, blending family utility with the sharper road manners and upscale finish that buyers expect from Acura. For owners keeping one on the road in original-style sizing, tire fitment comes down to two radial sizes: 245/55R19 and 245/60R18. Both were used on this exact model, so the first step is confirming which wheel diameter is on the vehicle before choosing a tire. Once that is settled, the decision shifts to road-use priorities, overall tire character, and making sure the current wheel and vehicle setup still matches the intended size.
Which Tire Size Is Right for The 2016 Acura Trucks MDX
The 2016 Acura Trucks MDX uses two primary tire sizes, and both are radial fitments. The key difference is wheel diameter: one size is built for an 18-inch rim and the other for a 19-inch rim. Because both the Base and SH-AWD can use either size, the most important step is confirming the actual wheels on the vehicle before selecting replacement tires.
245/55R19 is a metric radial size in which 245 identifies the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2016 Acura Trucks MDX, this size is one of the primary modern fitments and belongs on a 19-inch wheel. Its dimensions place it very close in overall height to the 18-inch alternative, but it is not the same fitment because the wheel diameter differs. This is the size to evaluate when the MDX is already equipped with 19-inch wheels and the goal is to stay with the correct wheel-based fitment.
245/60R18 is a metric radial size where 245 represents nominal section width in millimeters, 60 is the aspect ratio, R marks radial construction, and 18 indicates the required rim diameter in inches. For the 2016 Acura Trucks MDX, it is the companion primary fitment for vehicles running 18-inch wheels. Although its overall diameter is very close to the 19-inch tire option, the tire is built for a different wheel size and should be chosen only after confirming the actual rim diameter on the vehicle. It is the right size to consider when retaining the MDX's 18-inch wheel setup.
Tire fitment on the 2016 Acura Trucks MDX is straightforward in one sense and wheel-dependent in another. Both covered sub-models can use the same two radial sizes, so checking the exact wheel diameter on the vehicle matters more than choosing between Base and SH-AWD.

2016 Acura Trucks MDX Base
The 2016 Acura Trucks MDX Base can use either of the two primary radial sizes offered for this model. Tire selection starts with confirming whether the vehicle is on 18-inch or 19-inch wheels, then choosing a replacement that matches that wheel setup and the way the MDX is actually used.
The 2016 Acura Trucks MDX SH-AWD follows the same fitment pattern, with both primary radial sizes applying depending on wheel diameter. That means the practical decision is not trim-based so much as wheel-based, making it important to verify the current rim size before replacing tires.
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 a 2016 Acura Trucks MDX, the most useful tire questions center on identifying the correct 18-inch or 19-inch fitment, understanding what each size means, and checking wheel, suspension, and tire condition before regular road use.
Tire Size & Fitment
What tire size fits a 2016 Acura Trucks MDX?
The 2016 Acura Trucks MDX uses two primary tire sizes: 245/55R19 and 245/60R18. Both are radial fitments, and both apply to this exact model depending on the wheel setup on the vehicle.
The important distinction is rim diameter, not just tread size. A 245/55R19 belongs on a 19-inch wheel, while a 245/60R18 belongs on an 18-inch wheel. Before choosing tires, confirm the actual wheel size currently installed, especially if the MDX has seen wheel changes since new.
What size rim does a 2016 Acura Trucks MDX use?
A 2016 Acura Trucks MDX can use either an 18-inch or 19-inch rim, depending on which of its two primary tire sizes is on the vehicle. The 245/60R18 size uses an 18-inch rim, and the 245/55R19 size uses a 19-inch rim.
That wheel-diameter difference is the first thing to verify before replacing tires. The two sizes have similar overall tire height, but they are not meant for the same wheel. Checking the sidewall and measuring the actual rim diameter helps avoid ordering the right section width in the wrong wheel size.
Do all 2016 Acura Trucks MDX sub-models use the same tire size?
The 2016 Acura Trucks MDX Base and 2016 Acura Trucks MDX SH-AWD both use the same two primary tire sizes: 245/55R19 and 245/60R18. In that sense, fitment is shared across the covered sub-models rather than split by trim.
The practical check is still necessary because the vehicle may be on either wheel diameter. Instead of assuming fitment from the sub-model name alone, confirm whether the MDX has 18-inch or 19-inch wheels. That approach matters even more when a previous owner may have changed wheel packages.
Choosing the Right Tire
What should I consider when choosing a 245/55R19 or 245/60R18 tire for a 2016 Acura Trucks MDX?
Start with the correct primary size for the wheel already on the 2016 Acura Trucks MDX. The real choice is between 245/55R19 for a 19-inch wheel and 245/60R18 for an 18-inch wheel, not between two interchangeable tire sizes.
After size is confirmed, compare the tire's intended road-use character, construction consistency, and how closely it suits the vehicle's current setup. It also helps to inspect whether the MDX still has stock wheels and suspension, because changes in wheel package or ride height can affect how confidently a replacement size works in service.
How do I choose between the available 2016 Acura Trucks MDX tire sizes?
Choosing between the two 2016 Acura Trucks MDX tire sizes comes down to the wheel diameter on the vehicle. The 245/60R18 size is for an 18-inch wheel, while the 245/55R19 size is for a 19-inch wheel, and each should stay paired with its matching rim.
Because the two sizes are close in overall diameter, buyers sometimes focus on height and overlook wheel fitment. The safer approach is to verify the wheel first, then match the tire accordingly. Looking at the current sidewall marking is usually the quickest confirmation before moving on to brand and tire-category preferences.
What rim-fitment details matter when choosing tires for a 2016 Acura Trucks MDX?
The most important rim-fitment detail on a 2016 Acura Trucks MDX is diameter. This model uses either 18-inch or 19-inch wheel-based tire fitments, so the replacement tire must match the actual wheel diameter rather than just the nominal tread width.
It is also wise to confirm that the wheels on the vehicle are the ones intended for that tire size, especially on used MDX models. Aftermarket wheels, non-stock offsets, or previous wheel-package changes can alter clearance and overall fitment, even when the sidewall size itself appears familiar.
Restoration & Appearance
Does correct tire fitment matter for a 2016 Acura Trucks MDX restoration or preservation project?
Yes, correct tire fitment still matters on a 2016 Acura Trucks MDX even though it is a much newer vehicle than a traditional collector car. Staying with the proper 245/55R19 or 245/60R18 size helps preserve the intended wheel relationship and keeps the vehicle visually and mechanically consistent.
For an MDX being preserved in stock form, begin by confirming which wheel package the vehicle actually carries today. A later wheel swap can change the correct tire choice. Owners aiming for originality should compare the current setup against vehicle-specific records and trim-era references before changing sizes.
How does tire sizing affect the appearance of a well-kept 2016 Acura Trucks MDX?
Tire sizing has a visible effect on the stance and overall presentation of a 2016 Acura Trucks MDX because the vehicle was built around either an 18-inch or 19-inch wheel package. The correct paired size keeps the wheel opening and sidewall proportion in line with the intended factory-style look.
Appearance also depends on keeping the wheel and tire combination coherent rather than mixing sizes casually. A preserved MDX usually looks most settled when the tire matches the wheel diameter it was chosen for. That is why confirming the actual rim size is just as important for appearance as it is for fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Acura Trucks MDX?
Yes, modifications can affect tire fitment on a 2016 Acura Trucks MDX. Wheel changes, offset differences, suspension alterations, or lowering can all influence whether a 245/55R19 or 245/60R18 replacement still suits the vehicle's actual clearance and wheel setup.
A modified MDX should be checked more carefully than one that remains stock. Confirm wheel diameter first, then inspect sidewall-to-suspension clearance and turning clearance at the front. Even when the tire size itself is one of the original fitments, changes elsewhere on the vehicle can alter how comfortably that size works.
What should I inspect before driving a 2016 Acura Trucks MDX on new tires?
Before regular road use, inspect the wheel size, tire pressure, lug security, and the general condition of the wheels themselves. It is also smart to look over suspension components, alignment condition, and any signs of rubbing so the new tires on the 2016 Acura Trucks MDX start service on a sound platform.
A quick road test should confirm that the steering feels normal and that there is no contact over bumps or at full lock. Rechecking inflation after the first drives is worthwhile as well. That extra attention helps catch setup issues early, particularly on vehicles with replacement wheels or uneven wear history.
How often should tires on a 2016 Acura Trucks MDX be inspected?
Tires on a 2016 Acura Trucks MDX should be inspected routinely rather than only at replacement time. Regular checks for uneven wear, cuts, punctures, cracking, bulges, and slow air loss help catch problems before they affect ride quality, handling, or long-distance confidence.
Inspection matters even more on a lower-mileage vehicle that spends time parked, because age and storage conditions can matter as much as tread depth. Looking over the tires during pressure checks and before longer drives is a sensible habit. It also creates a good moment to confirm that the installed size still matches the wheel package.
