So the blazer is safe from this now. My jimmy has 15" wheels with 5.5" of side wall. If I had a flat on it (and if I had 2" blocks on it) there would be some suspension drag.

This being said, I have driven for 38 years and had one blow out on tires I knew were borderline (actually, worse than borderline, but I was a poor kid). My toys get maintained much better than any of my old cars ever did.

I think Gary (Katrina10) is right if you had a fully inflated tire on the otherside then the flat side MAY not hit (I think your pictures with the blocks simulate both tires being flat instead of one...)

You have to do what makes you feel safe. Good luck, Rg

Roger (raggedjim) your 3rd sentence is half right, what you put in (parentheses) is what I (ck5566) did to show when both rear tires are flat in a extreme circumstance for the clearance and or the Scrub line problem.
