4th Gen SR5 Wheel Information

I haven't seen a lot of specific information on what I am looking for. I tried searching, but I might have used the wrong key words. If you find something that answers my question I will promptly delete this thread.

Does any know the specification on the factory 16" SR5 wheels? The offset and backspacing mainly. Just trying to figure out if I can use my factory wheels with bigger than stock tires.

You mean can you use factory rims with bigger than stock size tires?

 

yes.. OP fixed

 

What size are you wanting to go to? A tire shop can tell you what will fit the rim but just cause it fits the rim it doesn't mean it will actually it on you 4Runner. You can't go much bigger than stock without changing the suspension or cutting plastic to accommodate the bigger size.
