2013 Acura Trucks sat at the premium end of the crossover market, blending Acura refinement with all-weather versatility in the MDX, RDX, and coupe-like ZDX. By this point Acura was firmly in the modern radial era, so tire choice is less about antique sizing conventions and more about matching the correct metric size to the right model and wheel package. Across 2013 Acura Trucks, three radial sizes appear over three models, with some overlap between the MDX and ZDX but not across the full range. The first step is confirming whether you have an MDX, RDX, or ZDX, then checking which wheel diameter and corresponding size belong on your specific vehicle.
Which Tire Size Is Right for Your 2013 Acura Trucks
Three tire sizes are used across 2013 Acura Trucks, and they vary by model rather than being shared across the full lineup. Because these sizes span both 18-inch and 19-inch wheel diameters, the real decision starts with confirming your model and wheel size first, especially if you are choosing for an MDX that could use more than one fitment. Understanding that distinction before choosing a product saves time and helps match the tire to the correct vehicle configuration.
Year(s): 2013|Fit(s): MDX|Construction: Radial|Rim: 18-in rim
The 255/55R18 is a radial metric size with a 255-millimeter section width, a 55-series aspect ratio, and fitment for an 18-inch wheel. This size is specific to the 2013 Acura Trucks MDX rather than universal across the year and make. It is the right path for an MDX owner who has the 18-inch wheel package and needs to stay with that original diameter and profile relationship.
Year(s): 2013|Fit(s): MDX, ZDX|Construction: Radial|Rim: 19-in rim
The 255/50R19 is a radial metric size with a 255-millimeter section width, a 50-series aspect ratio, and fitment for a 19-inch wheel. This size is shared by the 2013 Acura Trucks MDX and ZDX, so it is not exclusive to one model in the lineup. It suits owners who need the 19-inch fitment used on those vehicles and want to keep the correct wheel diameter and overall tire proportion for that application.
Year(s): 2013|Fit(s): RDX|Construction: Radial|Rim: 18-in rim
The 235/60R18 is a radial metric size with a 235-millimeter section width, a 60-series aspect ratio, and fitment for an 18-inch wheel. This size is specific to the 2013 Acura Trucks RDX and differs from the wider fitments used on the MDX and ZDX. It is the correct direction for an RDX owner who wants to maintain the model's intended wheel diameter and size relationship rather than borrowing a size from another Acura truck model.
Three Acura truck models are covered for 2013. Tire size varies by model, and the MDX spans two fitments while the RDX and ZDX each use one, so identifying the exact model is essential before narrowing down to a tire size. Select a model below to explore model-specific fitment history and the tires that apply to it.
2013 Acura Trucks MDX
The 2013 MDX was Acura’s established three-row luxury crossover, known for balancing family utility with a more car-like driving feel than many truck-based SUVs. MDX applications here mount on either 18-inch or 19-inch wheels depending on configuration, so wheel diameter matters before choosing tires.
The 2013 RDX represented Acura’s compact luxury crossover, sized below the MDX and aimed at buyers who wanted easier maneuverability with upscale comfort. Its tire fitment here mounts on 18-inch wheels, making it distinct from the wider 19-inch application shared elsewhere in the lineup.
The 2013 ZDX was Acura’s distinctive fastback crossover, blending SUV height with a more dramatic, coupe-like roofline and a niche luxury-market character. ZDX applications here mount on 19-inch wheels and share their tire size with one MDX fitment rather than the full Acura truck range.
These answers focus on how 2013 Acura Trucks tire sizing changes between the MDX, RDX, and ZDX, what the metric size codes mean, and what to check on a modern luxury crossover before fitting tires for regular use or long-term collector care.
Size Basics & Fitment
What tire sizes fit 2013 Acura Trucks vehicles?
2013 Acura Trucks vehicles use three radial tire sizes across the range: 255/55R18 for the MDX, 255/50R19 for the MDX and ZDX, and 235/60R18 for the RDX. The MDX is the only model that appears with two fitments, while the RDX and ZDX each stay with one size. That means there is no single tire size that fits every 2013 Acura truck model.
The practical takeaway is to confirm both your model and your wheel diameter before choosing a tire. An 18-inch fitment and a 19-inch fitment are not interchangeable just because they come from the same year and make. If you own an MDX, take an extra moment to verify whether your vehicle carries the 18-inch or 19-inch setup before moving on to product selection.
What does 255/50R19 mean on a 2013 Acura Trucks tire?
On a 2013 Acura Trucks tire, 255/50R19 means the tire is 255 millimeters wide, has a 50-series aspect ratio, uses radial construction, and mounts on a 19-inch wheel. Within the 2013 Acura Trucks range, that size applies to the ZDX and to certain MDX configurations. It is a modern metric radial format, which is standard for premium crossovers of this era.
That code matters because each part affects fitment. The 19 at the end must match the wheel diameter, while the width and profile influence overall proportions and how the tire sits on the vehicle. If your 2013 Acura Trucks vehicle is an MDX or ZDX, matching the full 255/50R19 code is more useful than relying on appearance alone.
Do all 2013 Acura Trucks models use the same tire size?
No, 2013 Acura Trucks models do not all use the same tire size. The RDX uses 235/60R18, the ZDX uses 255/50R19, and the MDX can use either 255/55R18 or 255/50R19 depending on its wheel package. Even within one model line, Acura used more than one size.
That variation means year and make alone are not enough to choose tires correctly. On a 2013 Acura Trucks vehicle, the model badge narrows the field, but the wheel diameter finishes the job. If you are replacing only tires, verify the code on the sidewall of the tires currently on the vehicle and compare it with the wheel size before making a final decision.
Buying the Right Tire
What brands make tires for 2013 Acura Trucks vehicles?
All three fitments used on 2013 Acura Trucks vehicles are modern radial metric sizes, and they fall into mainstream replacement categories rather than vintage bias-ply fitments. Brand choice therefore tends to center on finding the correct size and service category for a premium crossover application, especially for owners using an MDX, RDX, or ZDX as a regularly driven vehicle.
The better buying approach is to start with size accuracy first, then compare the individual product details for the exact fitment your model uses. Because the MDX appears in both 18-inch and 19-inch form, it is worth checking the vehicle carefully before comparing brands. Once the correct size is confirmed, you can weigh priorities such as appearance, driving use, and the kind of road manners you want from the tire.
What sidewall styles are available for 2013 Acura Trucks tires?
2013 Acura Trucks applications use modern metric radial sizing, so sidewall appearance typically follows contemporary crossover and SUV practice rather than period whitewall or bias-ply styling. For vehicles from this era, buyers usually focus less on sidewall ornamentation and more on matching the correct size, service description, and overall look that suits an OEM-style luxury crossover presentation.
That means sidewall choice is usually a finishing detail, not the starting point. If your goal is to keep a 2013 Acura Trucks vehicle looking close to factory character, a clean modern sidewall is generally the direction that fits the period. Once size and wheel diameter are confirmed, compare sidewall appearance among the exact products offered in your fitment rather than assuming every product in the size will look the same.
How do I choose the right tire for a 2013 Acura Trucks MDX if it uses two sizes?
A 2013 Acura Trucks MDX can use either 255/55R18 or 255/50R19, and the correct choice depends on which wheel diameter is on the vehicle. Both are radial metric sizes, so this is not a bias-ply-versus-radial decision. It is a direct fitment question tied to the wheel package and the tire code that matches it.
The safest approach is to confirm the wheel diameter first and then match the full sidewall size exactly. Do not substitute the 18-inch size for the 19-inch size, or the 19-inch size for the 18-inch size, without a planned wheel change. If the vehicle is new to you, checking the current sidewall marking and the wheel itself is the fastest way to avoid a costly mismatch.
Fitting & Setup
Do 2013 Acura Trucks tires require inner tubes?
2013 Acura Trucks vehicles use modern radial metric sizing, which is typically associated with tubeless passenger and crossover tire practice rather than tube-type collector fitments. The MDX, RDX, and ZDX all fall into a late-model luxury crossover era where tubeless operation is the norm when the wheel is designed and maintained for it.
Even so, the wheel condition still matters. If a wheel has corrosion, damage, or sealing problems, that issue should be corrected rather than worked around. Before installation on any 2013 Acura Trucks vehicle, inspect the wheel, valve stem area, and bead seats so the tire can perform as intended on a proper tubeless-ready assembly.
Can the original 2013 Acura Trucks wheels be used with all tire sizes?
Original 2013 Acura Trucks wheels can only be used with the tire size that matches their diameter. The 255/55R18 and 235/60R18 fit 18-inch wheels, while the 255/50R19 fits 19-inch wheels. Because the lineup uses more than one wheel diameter, there is no single original wheel that works with every size across the full range.
That matters most with the MDX, since it appears in both 18-inch and 19-inch form. An original 18-inch MDX wheel can stay in service with the correct 18-inch tire, but it cannot accept the 19-inch fitment. If you are unsure what is on the vehicle now, confirm the wheel diameter before comparing tread patterns or brand preferences.
Maintenance, Storage & Longevity
How should I store a 2013 Acura Trucks vehicle when the tires are fitted?
A 2013 Acura Trucks vehicle should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone sources. Clean the tires and wheels before storage, keep inflation pressures in the proper range for storage support, and move the vehicle periodically if it will sit for long stretches.
Those habits help preserve the rubber and reduce flat spotting or long-term sidewall stress. For a vehicle that will be parked for months, some owners also use tire cradles or stands to reduce static load, especially if the vehicle is part of a collection. A quick visual check every few weeks is far easier than discovering age cracks or pressure loss right before the next drive.
How long do tires on a 2013 Acura Trucks typically last?
Tires on a 2013 Acura Trucks vehicle should be evaluated by age as much as by wear. A good collector and enthusiast rule is to inspect them closely after about five to seven years and to treat the ten-year mark as a serious replacement point regardless of remaining tread. The DOT date code on the sidewall gives the tire’s week and year of manufacture.
That matters because many premium crossovers accumulate less mileage than their tread depth would suggest, especially second vehicles or low-use examples. A 2013 Acura Trucks tire can look usable while still aging out. If cracking, hardening, vibration, or repeated pressure loss begins to appear, age has become just as important as tread condition in deciding whether the tire should stay in service.
How often should tires on a 2013 Acura Trucks be inspected?
Tires on a 2013 Acura Trucks vehicle deserve a quick inspection before every drive and a more careful inspection before any extended outing. Look for sidewall cracking, cuts, bulges, uneven tread wear, punctures, and signs of slow air loss. Pressure should also be checked regularly, especially if the vehicle spends long periods parked.
That routine is particularly valuable on older luxury crossovers that may be driven seasonally or only for special trips. A problem that develops slowly in storage can become obvious only when the vehicle is loaded for highway use. Catching irregular wear early can also point to alignment, suspension, or inflation issues before they shorten the life of the next tire set.
Safety & Road Use
Are 2013 Acura Trucks tires safe for highway driving?
2013 Acura Trucks vehicles use modern radial metric tire sizes, which are appropriate to normal highway use when the tires are in good condition, correctly inflated, and matched to the vehicle’s required service category. Because these are modern crossover applications rather than antique bias-ply fitments, the larger safety question is usually tire age, wear, and maintenance rather than whether the size format itself is highway capable.
A healthy tire is only one part of the picture. On a 2013 Acura Trucks MDX, RDX, or ZDX, the suspension, brakes, alignment, and wheel condition should be checked along with the tires before regular highway use. If the tires are older, show cracking, or have an unknown service history, address that first instead of assuming tread depth alone makes them road ready.
What inflation pressure should I use for 2013 Acura Trucks tires?
Inflation pressure for 2013 Acura Trucks tires should follow the vehicle manufacturer’s recommendation for the exact model and wheel package, not a pressure borrowed from another Acura truck model or another tire size. The MDX, RDX, and ZDX do not all share the same fitment, so pressure guidance should be matched to the specific vehicle and the tire installed on it.
The most reliable places to confirm pressure are the driver-door placard, the owner’s manual, and the tire manufacturer’s guidance for the exact product. Use those sources together rather than relying on a general rule. Pressure checks should be done cold, and any persistent pressure loss should be treated as a maintenance issue rather than solved by simply adding more air.
What should I check before taking a 2013 Acura Trucks on a longer drive?
Before a longer drive in a 2013 Acura Trucks vehicle, inspect each tire for cracking, punctures, bulges, uneven wear, and proper inflation. Check the valve stems, confirm the spare is usable, and make sure the wheel nuts are secure and the wheels themselves show no visible damage. A test drive at local speeds can also reveal vibration or pull that deserves attention before a trip.
That tire check should be part of a broader pre-trip inspection suited to a vehicle that may not be driven daily. Brakes, fluids, battery condition, and suspension all matter, but the tires are the only part touching the road. Taking ten minutes to inspect them on a 2013 Acura Trucks vehicle can prevent a roadside problem and helps you catch age-related issues before they become a safety concern.
