    Do the rpm calculations for 80...not 60

    I have 35's on my truck now (bought gears when i was running 36's) and at 80, I was sitting at like 2800 RPM.

    I personally think 4.56 is perfect if you want performance gears. If you want something more realistic, somewhere between 4.10-4.56 (there is one in the middle, I can't remember what it is).

    With my 36's and 4.56 gears, I can still spin the tires pretty easily. Bigger tires don't do so well on traction
    blown transmissions are about as useful as 97% of the guys on this forum
