I assume you are trying to run this on a tacoma? If so, you will probably have a whole lot of rubbing, especially if you go with 33x12.50. I rubbed with 5" of lift and 33x12.50s. If the 3" lift is all you are getting i would go with 32s. You could add a 3" Cornfed suspension lift (about $350) and run 33s with no problems at all.
