They look pretty cool. Might be a little too wide for the rim. I know the 305 wide Nittos fit but a 315 might be pushing it.

I think that those would fit.

Jason, According to the tire calculator they will but you're lossing some sidewall height (1.5") which may give it a funny look.

Your right, I got almost exactly 1.5" difference doing my own calculations...

That would help a little for those of us still running 3.55's.

Being such a short side wall it probably wouldn't have enough flexibility to allow the tread to lay flat on our stock rim width being almost 1" wider in the tread.

It would probably work well with a widened wheel though, but still might look a little funny.

They will definitely look funny unless you really drop the truck a lot. And you're right about the less flexible sidewall not allowing all the tread to contact the ground. You probably wouldn't be effectively running more than a 300mm wide tire.
