For those concerned about fuel economy etc running a 35 and 4.10s, I have no problem running 80+ the entire way from Seattle to kalispell on less than a tank of fuel.

Fwiw, when I go 37's this summer, I'll be going 4.88's.

And for those of you scared of hurting your truck... Remember 4500's only have 30" tires and 4.88s.
