Lift without a "lift"
 

I was wondering how big of tires can i put on my truck to make it higher, without having to buy new wheels or put a lift kit on it.

what is your truck?

more info would help, if it's 2wd, then 265's if 4wd 285 both in 16's and 17' wheels... with coil spacers in my 02 2wd i have 285 70 17 bfg a/t which are pretty bad ass and worth the coin! i will never run any other tire on my truck, it gets bad ass traction on the road water and mud!
