A few more points. Our TT is a keystone 23RBWE. Tires were load C. It has a lot of carrying capacity. There are only 2 of us so we don't carry much. It can be hot in Phoenix, so we always leave very early. It was 104 in Iowa today. Should we all park until it cools down. I am a 68 year old disabled vet and I don't go over 65 without the TT. Usually 55 to 60 with it. None of the tires lost air so the others weren't stressed when they failed.
We put a lot of faith in these tires as everyone on here said they were the best. Hope this helps. Form your own opinions. That's all from me.
