Thinking about getten some aftermarket rims for my runner. What is the biggest rims and tires I can fit on 4g runner without rubbing? What is a good brand of SUV rims?

 

I think 22's would be the biggest rim you can put without rubbing. You would have to put between 45-35's. That's pretty thin. Depends on where you live. Here in NY, a pothole would kill my rims if I put 22's on my truck. For me, 20's would be enough. Tires would probably be 305/35 R22.

 

Do a search. Plenty of 4th Gens running aftermarket wheels...

 

do a search ... this question has been covered lots.

as far as the biggest tire without rubbing ... that would be a 265/70/17.
