Goodyear's Eagle LS tires
Thinking about buying (4) of the tires along with 20 inch rims for my 2005 F-150, 3:55 rear end and 5.4 engine. Right now I have 17 inch rims with small tires. I would like to go bigger tires mainly for looks. I have heard alot about changing the rear end gear ratio. Is this somethig I should do? The Goodyear tires have a outside diameter of 31 inches and the stock tires on the truck measure 29 inches. What is the corect gear ratio for 31 inch tires and are these tires any good?
