i have a 04 F150 heritage regular cab with a 4.6 and im gonna put 285/75/17 nitto terra grapplers on it and i was wondering how much this will affect gas mileage and power. i have a 3 inch body lift and it didnt seem like it affected anything. if anybody has a truck with these sized tires on it can they post a picture please

 

The power and mpg will drop a bit, easily fixed with a programmer.

 

what do you mean by a programmer

Thanks Stewart.

I should have really said that the power will be fixed with a programmer. After adding that much tire, the mpg's will be lowered no matter what you do.

 

A programmer will also allow you to correct the speedometer for the tire size change.

 

i put the tires on it and it dosent seem like it affected the power any
