I switch yesterday my stock tires 255/75/17 (32" Mud-Terrain) to 225/75/16 (which I believe are stock tires as well) because I wanted better gas mileage and better stability while driving.
The result is excellent, it's like a new jeep!
(I even have power on the 6th gear)
But... speedo is off by 10 km and the RPM is wrong (it seems like it kept the settings from the stock 32")
I was told by the dealer that I could switch between stock tires without a problem and the speedo would not be affected...
Is the dealer wrong? Do I need an AEV Procal to change the setting to stock tires 225/75/16.
My plan is to run the 225/75/16 during the summer and the 32" during winter.
Thank you for your help.
