I just put 33" Cooper STT's on my h3. I like them and they weren't that expensive- 200 per tire mounted and balanced. I was just wondering if there is a way to reprogram the speedo for the bigger tires. I looked in the frakin manual, but couldn't find anything. For those wondering- 65mph with 32's is gonna be the same as 62mph with 33's.

 

You will have to get your PCM reprogrammed. I had mine done by PCMforless when I changed my tire size. They can also change your shift points and ect. makes a nice difference.

 

Thanks Bennersj, I have the 5-speed and I have noticed that I'm staying in gear a little longer, I can see why you'd get the shift points changed.
