Default Question for those running 20" wheels

What size tyres are you running on the rear? Currently I have 10.5" rear wheels with 285 25 20 and have zero rubbing. As this size is hard to get in Australia, not to mention very expensive (about $500 each) would a 275 30 20 still work ok without rubbing and not look to stretched?
I have my car pretty low and will more than likely be wearing out rubber quickly due to the negative camber. Thought about putting figs adjustable lower control arms in but if I can get 15,000km plus out of a set of rear 275 30 ill just do that as there a lot cheaper and easy to get.

They will work with out much stretch, only thing that will be slightly off is the speedo, by 1.8%. I think it will read that your going slightly faster than what your speedo is showing. Your previous tires were about the opposite, 1.6% smaller than stock size, I say go for it.

I am lowered on Swift springs and I used to have 275/30/20 in the rear. My offset was plus 45 and I rubbed.
