I think it all depends what you intend to use it for. I don't get the stretch look on something that is going to be thrown around and is mean't to be a performance car but if its just for cruizing around in i can see any issues and have never experienced any problems.
I have a few with stretch, one with a lot of stretch and some without.
Don't think i'm going to be popular with this one
This is the lot of stretch (195/45/14 on a 10" rear rim and 8" front rim):
Never had any issues with tyres popping off rims etc
Oh it has rust as well sorry but it was rough to start with.
My benz runs 225/40/18 on 8 and 8.5" width rims with no issues, it wont run 235s
