Attention: TDR Forum Junkies 
The service tech at the dealership said he could recalibrate for 285/70/17 size tires but couldn't go any larger than that. I really want to put 35s on my truck but I don't want to void the warranty with a "tuner". Any ideas?
If the ECM is not reprogrammed, is this detrimental to the engine's function or is it just that the speedomenter/odometer is wrong?
