ordered the 751's and 763's and my original plans were to go with 275/70/18 firestone destination mt's but i'm wondering if the 305/60/18 bfg km2's are too wide for stock wheels and no spacers (planning on terrafirmas but don't have the $ yet)

anybody have any info or any experience with this tire size?

 

On what year truck, do you have a CDL, lockers and are you aware of the 3 to 4 MPG drop you will be getting. Why going big with 18" wheels, what sort of wheeling will you be doing?

 

that is a really wide tire. i am running 275/70/18 now and would not want to go any wider. i think you would definately get some rubbing with something that wide
