What tires come on an Acura MDX?
There isn’t a single tire that comes on every Acura MDX. The factory tires depend on the model year, trim level, and wheel option. In recent generations, MDXs have shipped with all-season tires on wheels ranging from 18 to 20 inches in diameter.
To understand exactly what tires your MDX should have, you need to consider your specific model year and trim. The following guide explains common configurations and how to verify the correct size for your vehicle.
Understanding the variations by model year and trim
The MDX’s tire spec changes with updates to wheels, trims, and markets. While there isn’t a universal tire for all MDXs, most modern models use all-season tires paired with 18-, 19-, or 20-inch wheels depending on the package selected.
Common OEM configurations by wheel size for recent MDX models provide a rough guide to what you might see. Regional differences and optional wheel choices can alter the exact size.
- 18-inch wheels: typically around 245/60R18 (all-season tires common on base trims)
- 19-inch wheels: typically around 255/55R19 (all-season or touring tires on mid-to-higher trims)
- 20-inch wheels: typically around 255/45R20 (all-season or performance-oriented tires on upper trims or with wheel upgrades)
As you can see, the exact tire size depends on the wheel diameter chosen with your MDX. Always verify with the door placard or owner's manual to avoid incorrect replacements.
How to confirm the exact tire size for your MDX
To confirm the exact size for your specific MDX, follow these steps:
- Look at the tire sidewall for the size imprint (for example, P245/60R18 105T). This shows width, aspect ratio, and diameter.
- Check the driver’s door jamb placard, which lists the standard tire size and inflation pressure for your vehicle.
- Consult the owner's manual or the original window sticker (Monroney label) if you have access to it.
- Use the VIN to pull the original equipment specification from Acura’s official portals or your dealer’s service database.
If you’ve swapped wheels or are considering aftermarket tires, make sure the new size remains within the manufacturer’s recommended range and preserves proper contact with the fenders and suspension.
OEM vs replacement tires: what to know
When replacing tires, you generally want to stay close to the OEM specifications for optimal handling, braking, and warranty considerations. Here are key points to keep in mind:
- Match the tire width, aspect ratio, and wheel diameter when possible to maintain the vehicle’s designed stance and performance.
- Ensure the load index and speed rating meet or exceed the MDX’s requirements for your model year and trim.
- Consider the type of tire (all-season, touring, or performance) that matches your driving climate and habits.
- If you mix tire brands or tread patterns, preserve even wear by aligning and rotating tires at the recommended intervals.
For all replacements, verify compatibility with your MDX’s wheel size and any driver-assistance sensors that may interact with tire dimensions.
Variant: MDX Type S
The MDX Type S is a higher-performance variant that typically uses larger wheels and may require different tire specifications than base or mid-range models. Exact sizes can vary by model year and wheel option, so always check the VIN and the vehicle’s documentation or consult an Acura dealer to confirm the precise OEM tire size and type for your Type S configuration.
Summary
In short, there is no one-size-fits-all tire for the Acura MDX. The OEM tire size depends on the model year, trim, and wheel choice, with common configurations spanning 18-, 19-, and 20-inch wheels and corresponding all-season tires. To determine the exact tire size for your vehicle, check the door placard, consult the owner's manual or window sticker, and verify with your dealer or service records based on your VIN. When replacing tires, aim to stay within OEM specifications to preserve handling, safety, and warranty coverage.
