Wanting to change wheels but ......

I was wondering if i change tire size do what do i need to do to keep the speedo correct? I currently have 17 on my 03. Reason is ask i see a lot of large tires on craiglist but all larger. I dont want it to ride like a dump truck either. thanks in advance.

if the height of the tire doesnt change you dont need to worry. if it does, you can have your ecu retuned to compensate for the change. there is probably a local speed shop ormaybe even a dealership that will change it for you for a small fee. i had mine corrected when i had my engine tuning done.

if you cant find someone local to adjust, talk to the folks at blackbear performance - they are preferred vendors on the forum here, they can help you out.
