Widest tire you can run on a 10.5 wide wheel

Whats the widest tire you can run on it without going to wide??

I'd say you were safe to at least 315. I've got 315's on my 11" wheels and they are a good fit (could go wider if I wanted to). Tire charts usually show 315 to be the widest on the 10.5" though.
