I have a 2011 F-150 supercab 4x4 with the 5.0, i have the 275-55-20's. I got over 66,000 miles on these tires. They were awesome until about 45,000 miles then seemed to lose their traction in the rain. they are very quiet and resist punctures. I had them rotated every 5000 miles with my oil changes by the ford dealer. They are way better then the good years which are so loud they will give you a headache. they have outlasted any other tire i have ever owned. They are better then any other tire on dry pavement, but the BF Goodrich all terrain t/a's are much better in the sand and mud if you can take the noise. The only down fall is the price.
