Can anyone tell me what the largest diameter tire will fit on a 2000 4-Runner Sport Edition? It has the big fender flares. My guess is that it is the 265, however I was able to fit a slightly larger tire on my pre-runner, so I am wondering if I can do the same on the runner?

 

While we're at it, can someone tell me about 15" rims vs. 16" and therotors they go over? I have a 97 4Runner with 16" wheels but I would like to use my 15" rims with the 31" tires I had on my 94 rig. Any suggestions?
