    I just was given my first truck. it is a 2002 gmc duramax. I installed a 8" lift kit and 37x14x20 inch tires. I am looking to downsize to a 35 inch tire but I don't want the truck to be top heavy. so should I run 35x12.50 or 35x13.50? thanks

    width of your tire has nothing to due with power...
    there is pros and cons:
    pros: increased traction
    cons: more rolling resistance (drag)

    so I will not lose power due to wider tires? im really leaning to 36x13.50x20 tires because the 35s would look small with a 8 inch lift

    no there would be no power loss, that only changes when tire diameter changes

    but the more drag, the more it affects your mpg

    Yes, more drag or rolling resistance will effect mpg. But, in my personal opinion tall skinny tires look silly on a truck. I ran 36's x 14.5 when my 95 was my daily driver then I switched to 38.5x 16.5, I ran Dick Cepek radial fun country tires when I had the 36. The tread pattern is not aggressive and they rode very nicely. A less aggressive tread pattern equals less rolling resistance. Lets face it though, running 35's you are not all that worried about the 1/4 of a mile that you are going to lose per gallon (just an estimate), you have a duramax which is plenty of torque, and you are switching from a 37" tire, with any width in a 35" tire you are doing to notice an increase in power.

    The biggest downfall I see to a wider tire is keeping the paint clean. My 38's throw water and crap all over the side of the truck.

    Changed the title to be more descriptive.
