Anybody running 17" Cobra Bullit rims on a Duster

I tried to get some 275/40R17's mounted on some 17x8 rims and the guy couldn't get the sidewall to squeeze down enough to get it mounted. He was a friend that has some equipment, but not a shop, so maybe he just didn't try hard enough and gave up early.

I know it's been done, but it didn't work out for me. Just an FYI.
