What size tires can I put on my 2007 Acura MDX?
The 2007 Acura MDX typically uses 245/65R17 on the standard 17-inch wheels, or 255/60R18 on the optional 18-inch wheels. Your exact size should be verified on the driver’s door jamb sticker or in the owner's manual, but these two sizes cover the common factory configurations for that year.
Stock tire sizes for the 2007 MDX
The following sizes correspond to the most common factory configurations depending on wheel diameter. Use them as a reference when matching replacements.
- P245/65R17 — fits the standard 17-inch wheels found on base and some mid-level trims.
- P255/60R18 — fits the optional 18-inch wheels often found on higher trims or packages.
Always confirm the exact size on your specific vehicle, since variations by market or package can occur. The door placard in the driver’s door jamb lists the precise tire size and recommended inflation pressure for your MDX.
Safe size swaps and how to choose
If you’re considering changing tire size for aesthetics or performance, here are guidelines to help keep your MDX safe and functional.
- Keep the overall tire diameter within roughly 3% of the original to avoid affecting the speedometer, odometer, and vehicle systems like ABS and traction control.
- Ensure the load index and speed rating meet or exceed the original specifications to maintain safety and handling.
- Check wheel width and offset to prevent rubbing or clearance issues with fenders, suspension components, or brake calipers.
- For winter driving, you can install winter tires of the same overall diameter, or consult a professional if you’re considering a different size.
- When using aftermarket wheels, verify compatibility for hub bore and lug pattern. If unsure, seek installation guidance to avoid fitment problems.
With any size change, consult a tire professional or your local Acura dealer to confirm compatibility with your specific MDX configuration and to perform any necessary recalibration or alignment checks.
Important considerations for MDX tires
Speedometer, odometer, and drivetrain systems
Changing tire diameter affects the accuracy of the speedometer and odometer and can influence ABS/traction-control performance. A noticeable difference may require recalibration or software updates, so verify readings with a GPS and consult a technician if you deviate from stock sizes.
Load rating, performance, and tire type
Always match or exceed the original load rating to support the MDX’s weight and payload. Choose tire types appropriate for your climate and driving style (all-season for year-round use, winter tires in cold regions, and performance tires only if you understand the trade-offs in ride comfort and wear).
Fitment and installation considerations
Ensure the selected size fits your wheels and clearance around the fenders, suspension, and braking components. If upgrading wheels to a larger diameter, confirm that the new tires maintain a similar overall diameter and that the wheel width and offset won’t cause rubbing.
Summary
For a 2007 Acura MDX, the typical factory sizes are 245/65R17 on 17-inch wheels and 255/60R18 on 18-inch wheels. When considering any size change, aim to keep overall diameter close to stock, ensure proper load and speed ratings, and verify fitment with your specific vehicle. Always consult the door jamb placard or owner’s manual, and when in doubt, seek professional guidance to preserve safety and performance.
