285 tires hurting mpg ?
How much do you think my 285's are hurting my MPG's ? I have the smarty jr and I am trying maximize fuel efficiency with price of fuel the way it is !! Would it be worth selling the 285's and going back to 265's ? Thanks Pete

A wider contact patch does create more drag. A lot also depends on the tread and rubber composition. An off road or mud tread will create a lot more drag than an all season tread.

If you use a 285/70 you will have the width but not the height of the 285/75. That will also help to keep a little extra height but not hurt mileage.

I wish the tire folks would release a 265-80-17 which would be similiar to a 265-70-19.5. Skinny and tall with a e-rating.
