2007 F150,XL,regular cab
My truck came with 235/70/17 tires from the factory.I replaced those with Cooper 245/70/17 tires.The factory offers another tire size for my truck,255/65/17.Can anyone give me any details on this size tire? Will it throw off the speed,is it wider,more roll,less roll,better gas mileage,etc?
