I was looking at rims and I would like to know whats the biggest size rim that could fit on my 1995 S10/Blazer?
I would probobly pair the rims with low-profile tires.

17's or 18's are probably the biggest u wanna go. just remember that bigger wheels and tires = side effects like worse performance/mpg, and wear on suspension components and brakes due to greater rolling mass. upgrading the brakes would be a very good idea

ok, but how big will fit?
Like will 20" fit with low profile tires?

yes i believe 20's would fit with 30 or 35 series low profiles.

my buddy has an s10 with 20's on it, he cant turn his wheel all the way without it rubbing, i think he said like 1 1/4 is all he gets out of his. ill double check that, but i know his turning radius has sufferd alot

18s with 255/55/18's work perfectly and are an exact match for a P235/75r/15.

I know, I have them.

Don't go any higher or it will look totally retarded and you won't be able to turn.

You are looking at such a harsh ride with any tire that has a profile any lower then 55. Good luck and take pics!

Even with 55 it is a tight as hell.
