I thought about going with 33s instead of 35s, (I have 32s now so whats another inch) I made up my mind I would not be happy with 33s so i ordered 35s FIERCE TIRES ATTITUDE M/T 35-1250 R17LT. During the 2 months it took me to make up my mind on what tires to get i kept my eye on my RPMs I would go down the road in 6th at about 1600 RPMs. My tires should up, after getting them mounted I was driving home and watching my RPMs, no differents
My jeep seems to have no loss of power or anything. Iam wondering if I really have 3.21 gears. When I had my stock tires on I was getting about 19.5 mpg acording to the computer, now that i put on 35s it says 18.5 miles after driving 100 miles. I know the computer is not accurate but I used it for both.
