Can anyone who has this size tire tell me what MPG they are getting with them and what they were getting before putting them on? I think this will be my deciding factor.

Thanks,
Kris

Depends on what size tires you have on the your truck before you upgrade. I went from a 255/70/17 to the 305/65/18, and really didn't notice any loss in gas mileage. But then again i don't calculate gas mileage, and don't have the mini message center that displays MPG's. I just fill 'er up, drive, rinse and repeat.

yeah I would be interested too. Will be going from 285's to 305's soon and was kinda wondering if anybody noticed much of a difference. They are around 10 lbs heavier, and almost an inch wider and taller.

I went from factory 275's to the 305's and lost about 2 mpg. I went from around 14.5 in mixed driving to around 12.8. But boy do they look great!
