Finding deals on 15" rims but for some reason thought id heard that you cant run anything less than 16's on a 4 Runner? 16" deals are hard to find so any idea what backspacing i need for 15" rims on 33" tires? Thanks alot

 

Considering a 33" inch tire is still a 33" tire reguardless if you have 15's, 16's, 17's, etc, you would think it would be the same backspacing as a 16x8.

 

someone on another board said if i have 16" now then 15's wont work due to brake clearance??

 

yup. the brakes on 16" wheel rigs (OEM) are larger. Most 15" rim won't fit.
