I figured id start a thread about the drivability and opinions of running stock gears and bigger tires. I have 31's on a 4.5lift with the stock 3.07gears and 5th gear is not usable. I run it up to 60 in 4th and put it in 5th then i watch it fall on its face and bog down to wear i have to pop her in forth. Then i thought gas mileage would actuallly be better to run 60mph in 4th gear cause the motor is running in the torquey range. Instead of in 5th dogging it and making the engine run harder and takes more gas. Am i right? any opinions welcome
