hey guys - i am running a 2006 V6 auto trans limited -with a jba 3.5 inch econolift+kk forks. I have 4.10 gears. Currently running 245/75R16 MT's. thing is i want bigger tires. cause...well.... cause i can. Anyways - the options are 235/85R16 or 265/75 R16 - or just go for 31's - that really aren't that bigger than the ones i got now. It's needless to say - i dont want serious power loss. at least not serious power loss. How bad are those tire options gonna be as far as power goes?
