I don't even think a 245/40 would stay on... I've seen 245/45/17 on a 7", but it looks kinda silly.
On my met red t-top car I'm going with 235/45/17 rear (and 215/45/17 front) which is about the biggest I'd put on a 7" wide wheel. Man I wish they were 8" in the rear! (ho well :S)
I'll post pics when the new tires are on *monday!*
Best!
Ben.
