Trading Wheels
I am just curious and want to learn.
There are a couple of threads that want to trade wheels IE: different diameter. How is the accuracy of the speedometer changed to read correctly? Is it just a matter of another visit to the dealer for a reprogram?
Mind you I am not looking to do this I am just wondering...

Re: Trading Wheels
i too am interested. i have seen posts about people getting 265/65/18 bfg at's, same wheel, but a bit bigger than the stock 265/60/18....i believe that means the speed will be 3.4% too slow. i wonder how easy it is to recalibrate the speedo and odometer...

Re: Trading Wheels
The dealer is able to adjust the speedo for up to 2" of tire diameter change. Anything bigger will need an aftermarket tuner.

I went from stock 29" tires to 32" tires and my speedo is 5mph slow.
