I have a 95 4x4 4runner. And i dont know much about tires/wheels at all. But I have 15'' rims. I have been searching through and through but i cant find where nitto makes a trail or terra grappler for a 15'' wheel. Do i need to get some new wheels maybe 16'' or 17''. I dont have the money for anything fanncy on the wheels though. Im so out of the loop on this stuff and if I go into a shop with these kind of questions i feel like i will be ripped off. There is very little tread left on my tires now so I need to make a decision soon.
