On the '06 and up models, can the CANBUS computer be adjusted to compensate for the addition of 35's?
What have you guys with 35's/37's or larger done to compensate and get the speedo/odo to read correctly?
The StarScan tool lists 285's as the largest tire fittable for speedo correction and the dealer doesn't know how to set it for 315's.

Any advice appreciated!

not sure, but a gps unit will give you the speed, and if your miles are off, they are off on your side, your warranty is longer as far as miles go.

My dealer said they can only go to 285's. My gps says I am approx 10% off.

I have heard there isnt as much adj in the newer... but a Smarty or Smarty Jr can do this for you. Jr is great for EGT's as well
