February 16, 2009I have had my new BFG all terrains now since the thanksgiving break in size 285/70/17 and my gas mileage is crap with a capitol C!! I do mostly highway driving so its killing me.
I was usually getting 20 highway with stockers and ohh...normal in town 16 *or* so...Now I cant even get 16 on the highway! Is it just a recal needed on the ''ole computer *or* am I just gonna have to get over it due to the size difference. I was ready for a mile *or* two decrease but 6 and 7 is outrageous.
Thanks for any help.
