ok so i recently bought a 90 4runner 3.0 v6 with a manual trans. wat im wondering is what the max size tires i can run without having to regear. currently it has 31 10.50 r15 but they are dry rotted hence the new ones. money is tight right now so im trying to find a good set of tires that wont look bad on this runner even after its lifted (sits bone stock for now planning on doing a lift when i get the cash saved up) been looking at some bfg 33 10.50 15 km2s any help and/or input will be greatly appreciated.
