ok, im in a 97 blazer, 4 door,4 wheel drive. will these rims fit?

 

Thats a wide a$$ tire but it should fit. I ve seen wider tires on a blazer. the diameter of those wheels/tires will be about an 1" taller then stock. So your speedo will be off by almost 2mph. speedo shows 60 your actual speed would be 62mph. Now the question is what is the offset on those wheels? Thats where you could run into a problem.

 

That is the same tire size I ran on my 20's when I was stock height. Yes they will fit.
