Well when you start getting into the 37s range, from what I hear you more "float" down the highway than drive down the highway, lol.

That's one of the reasons 35s is the largest I'll go.

Old but still

I know this is an old thread but I wanted to let you know that I run my 35x12.5x35 at 28-30psi and still don't have the outside edge wearing much. Make sure you do the chalk test and see what yours do and adjust accordingly for optimum wear.

I ran them at 35 psi ( both 35s & 37s)to avoid outer lug wear
