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.
Thanks for the extra info. Is it fair to assume that you stuck with the original-spec load range "C" because the OEM wheels are limited to 50 lbs. of pressure?
If so:
I agree with Capriracer, who said that the OEM tires were/are sadly underspec'd by the trailer maker- four LR"C"s supply about 7,000 pounds of carrying capacity, and the gross weight of that trailer is several hundred pounds over that. While I certainly believe that you aren't carrying the full gross weight, I think it outrageous that the trailer was supplied to you with what appear to me to be wheels/tires inadequate to carry the gross stated by the trailermaker. (Given at
this link as 7500 pounds for the 2010 model).
Especially given the variations in tire load caused by loading patterns and shifting road conditions, this seems to me to be a classic case of manufacturer supplying original OE tires/wheels woefully inadequate for the job. I think that trailer should have been equipped with LR "D" tires and wheels to begin with, but I s'pose that would have cost the trailermaker a few more dollars. And given the limitations of the original wheel, you were forced to stay with the original numbers...
Unfortunately for you, correcting that mistake now probably necessitates the purchase of new wheels that will handle the higher pressure required for the tires you should have received to begin with.
As per brand:
That's of course up to you, but it seems to me that the trailermaker's underspec is more likely the culprit in this case than the brand of the tire.
