Yes, they're 35x10.5 - mounted on steel 3.5" offset wheels. A friend of mine bought them to use in mud bog competitions on his SAS'ed hardbody and he won everything he entered with them - and then he sold 'em to me cheeeap

I like the tall-but-skinny size.
The big lugs really grab onto stuff well. MT/Rs are great all around tires - but comparing them to an offroad-only bias ply tire is like comparing a running shoe to a soccer cleat
These things kicked ass in the rocks.

I saw a review online where someone said they might slip sideways more easily than other tires on slick off camber stuff because the lugs can act like little skis... I haven't had a chance to verify or debunk that yet.

I wouldn't use them extensively on the road, though. They howl like crazy. Right now I'm still running my BFG MTs as "street" tires. I'll probably get a set of 33x12.5 BFG ATs at some point so I can really have separate onroad and offroad sets.
