Simple tire is the easiest and cheapest way to buy tires. They also have tires that the others don't even offer.
I wasn't the usual driver of the car but when I did I felt well attached to the road. Unfortunately the F**d they were on on failed inspection beyond a reasonable repair, so I didn't get the full experience with these tires.
Touring along New Englad coastline, riding like a dream!
These are load range E radial trailer tires. I use them on my 27 foot enclosed trailer. I load it heavy and work them hard. No failures so far in 15K miles (first set). I really can not comment on ride, or traction. They seem to work fine and the trailer stays behind the truck in all weather conditions. They seem to be a good value for people who don't put a lot of miles on their trailers. In the past my tire failures have been due to aged out tires. So with these I can afford to replace them when they are 5 years old even if they still have good tread.
Have not had the tires long. I am exceptionally happy with my purchase though. They handle well on my trailer. I have not had them long enough for some of the rating questions. Easy purchase and every thing was as I hoped.
Perfect tires for what I needed
