Size of rear tires?

[78Shorty]

I have 15 inch Ralley Rims with 225/60/15 on all four wheels. I want to put wider and a bit taller on the back, what's everyone running? Pics if you have them as well please.

I bought 275/60 for mine. Never put them on yet though.

I'm in the same boat. I have a 76 LWB GMC with 225/75R15 tires. I'd like a taller tire/wheel, so thinking of getting 17" wheels. Let's see what people show us!

There was a set of 31's on the rear of one suburban a friend of mine bought couple of years ago.
