i saw a set of the bfg km2's in person today and i love the tread on them. does anyone know how the tread wear is on them and what mileage could you expect to get out of them and will there be a large noticable visual difference between a 325/60r18 and a 305/60r18 because the bfg's only come in the 305

 

305/60 is about a 33" tire so you should be fine with that, and might be able to go bigger depending on the specs of the wheels you are getting.

I would think you could get 40K out of a set, and maybe more depending on your driving style.

 

ive ultra goliaths on the was they are 18x9's but for the life of me i cant find the backspacing, offset, ect. of these wheels
