I'm raising the BS flag on that... not with how heavy these trucks are. I suppose its theoretically possible, but i doubt anyone has EVER gotten 80k out of a set.

 

I was told I could get 80k out of mine. I will never see it happen though.

 

Realistically about 50k miles if properly maintained. There is little difference between the Toyo M/Ts and the Nitto Trail Graps, as they are sister companies, the tread pattern and compound are just about identical...

 

I've got about 20k miles on mine and they are worn about half way. My truck sees some hard driving though, both on and off road. Wheel-spin probably doesn't help either .

 

It's do-able, not saying its realistic but definately do-able. I've seen a set in the high 60's with enough tread left. Haven't seen them since though.

 

50k miles seems decent for a tire like that. I am assuming that going from an A/T to a M/T I will lose about 1 to 2 mpg's. Is that and accurate guess or will there not be much difference?
