Tire and Rim Question - Click HERE for Original Thread

1stMDX
Just got an 05 MDX and thinking of getting 19" or 20" rims for a more sportier look.
Questions:
1. Do larger wheels have an impact on odometer readings and gas mileage?
2. Do larger/wider tires improve performance and handling?
3. Anything else I should consider when shopping for wheels?

Thanks in advance to anyone with insight on this topic.

Yes and No.

If you are concerned about performance and handling, go with 18"/19". Anything bigger simply add too much weight and alter the geometry that will impact the high speed handling.

The following setup will keep your odometer readings almost the same as stock:

18" - 255/55/18
19" - 255/50/19

On the performance and handling, the acceleration may suffer unless you go with ultra light forged alloy wheels. The stock wheels are already among the lighter ones.

Snow and ice handling may suffer with wider tires, too.

Otherwise, with proper tire and suspension tuning, the lower profile and wider tires would provide better
braking and handling in most dry/wet conditions.

Go to this site to determine if there is a difference in the speedometer if you change the wheel/tire size.
