I am new here but have been lurking for a while and bought an 08 T4R last week. I have some 15" wheels in my basement from when I had a 2000 Tacoma. I have tried to search for this several ways and didn't find any definitive answers yes or no regarding this. From searching, the Sports and limiteds have larger rotors than the SR5 and require a minimum 17" wheel. It looks like the general consensus is that a 16" is the smallest that will clear the caliper. Has anyone actually tried to fit a 15" rim on a 4th gen 4runner? I appreciate any info and thanks for all the great info I've read so far.
