Well, I just did i calculation from my old tires to my new ones, seems now that my truck will read that i am doing only 57MPH when I am really doing 60MPH. my 05 had the 16 inch BFG tires and those off road rims. I think they were 265/70/R16 if I remember right. I now have a 285 tire with 22 inch rims. so my new size is now 285/45R22 Website shows i am about 5% off. not much. Consider the benefit. If you ever wanna sell your Tundy... God forbid, then your odometer will show lower mileage then what is really on the truck! The bad thing... if you are on the freeway doing a bit over 74MPH according to the speedometer, the cop may actualy get you going at maybe 78-80 MPH since the faster you drive on bigger tires, the more the ratio goes up for actual speed, so you may get a speeding ticket, just a heads up!! also with my 285 tire on regular suspension and no lift, i clear fine and dont rub, if i have a lil more weight in the truck say like a passenger, and i do a fast u turn, i occasianlly hear a slight rub, very slight, not enough to even cause a problem!!
