I ran two of these on my Demco Kar Kaddy. I towed a Kia Soul (2700 pounds) on them for about 500 miles. No problem. I then tried to tow my Ford Ranger 4x4 XLT (3800 pounds) on the tow dolly, and one tire failed in about 350 miles. Luckily the bubble on the side of the tire held until I reached my destination, but the tire was losing air pressure. I was towing the truck across the desert between Flagstaff AZ and Cortez CO. Lots of open highway - almost no vehicle services. I wouldn't recommend these tires at all, especially for weights anywhere near their maximum weight capacity which is 1764 pounds. Remember, on my tow dolly, the rear tires are on the pavement so not all the weight of the vehicle is distributed between the two dolly tires. For the most part I have never had much luck with ST (trailer) tires. I'm not sure a good set of truck tires wouldn't do as good and last much longer.

They have been excellent tires run very good, quiet, and I'm glad I bought them.

They have been great tires mounted on my 5th wheel camper.

Very happy with this tire on boat trailer. Doesn't squeal, ride is very smooth. Experience with Simpletire has been great- price and quick delivery.
