I was thinking of replacing my stock 31X10.5 R15 BFG A/T's with something a little bigger (perhaps the 32X11.5 if they will fit). My truck is supercharged, and I was wondering if any of you have done this with a supercharger and experienced pinging from the increased tire weight when under load. Also, I know there is a perceived power loss from bigger tires, but will one size up really make any difference? Under any other circumstances, I'd just deal with the power loss, but in this case, I don't want to cause premature tranny failure or cause the engine to detonate just for the sake of "looking cool."
Thanks for any info at all! <img src="/forums/images/graemlins/patriot.gif" alt="" />

My truck is '02 DC w/SC,TRD Header&Exhaust V6 Auto Trans. and 32" or 265/75R-16 MTR tires. I have experiencing power loss right after switching tires, but then gain some power after I installed SC, however, the gas mileage is terrible with SC and bigger tires, and I don't step on the gas pedal very hard, and that will avoid the tranny problem... hopefully. Also, I have been using Mobil 1 syn. oil and Mobil 1 syn auto trans oil since the truck has only 3k on it.

I have a 99 with 32's on it and I've been running the truck with 32's since 40k miles and it has 85k now and I've never had a problem. There is a little bit of power loss but to be honest it isnt that much and I barely even notice. Gas mileage went down a little bit and now I get anywhere from 16-18 where with 31's I would get 17-19. Hope that helps ya <img src="/forums/images/graemlins/kewl.gif" alt="" />
