Slow shift points.

[Mrgrumpy]

So I upgraded my stock tires from the 245/55R17 to 255/60R17 (M/T). Does anyone notice upgrading the tire gives you slower shift points and doesn't go to 8th gear as often anymore? Does anyone have any recommendations to fix this or info if this is just how the Jeep will function from now on.

You can go to the dealer and they can reprogram the tires/shift points. I paid $125 for this a year ago. Alternatively, I believe you can buy a Tazer and do it yourself.

I have 315/70/17's and after my reprogram it shifts just like stock again.

I think you posted the wrong tire sizes BTW.
