Question about changing wheel diameter in hptuners I just put 295/35/18's on the back and when I go into hptuners it says the stock tire size is 24.91? Although I know that the stock diameter is 25.6 and the new tire is 26.12. So what would I enter in the hptuners diagram also it give me the option to scale the auto shift tables with the new tires will that allow my shift points to stay the same with the new tire size or would i have to alter those also?

one other thing is will that 1/2" on tire diameter mess up wot shift points if I dont correct it or will it be ok? From what I've read the tire height shouldnt affect wot shifts because the pcm gets its speed signal from the vss in the tranny is that correct?
