I drive a 1993 Ford F350 crew cab dually. I pull a horse trailer quite a bit. I bought this truck 12 years ago and put these tires on right after I bought it. The tires still look very good. I have decided to replace them just due to the age. I don't want a blow out with the trailer. These are the best tires I have ever seen for on highway driving. I did live in snow country for three years and the tires worked well. Just needed weight in the bed of the truck. I cannot say enough good about these tires. 86,000 miles and the tires still look good. What more could anyone want.
