BFG KO2 275/60R20 or 275/65R20?

I went with 275 60 20 ko 2s with a 1.5" level and I love it. I tow my travel trailer, take it off road and drive mountain passes frequently so im glad i went with the 60s. I didn't want to decrease my gearing too much, the tires get heavier the larger they are...and you only gain .5" of lift which is realistically nothing. The 60s are also d rated and a better match for a half ton truck than the e rated ones. I love the way they look and would do it again

I did the same thing for the same reasons - very happy with the D-rated 60s

Mines a 5.4. I lost maybe 1 mpg at the most. Compared to scorpions, or other comparable stock tires it will drop a bit. Heavier, bulky, a more resistant tread pattern, etc. I get around 18mpg average. I mainly do highway driving, but i'm always either ascending or descending mountains. If I baby it at 90-100km an hour I can get 20, if i fly up the hills at 130km an hour ill get 15. It's all relative to your driving style & conditions, so take what people say their MPG is with a grain of salt.
