I am happy with the Maxxis UEs on my Casita
. I am guessing we have nearly 20,000 miles in about two years with them and they still look like new. As Tom said, they are sold as commercial vehicle tires in Europe and trailer tires here. They are marked "Light Truck" but they are not marked LT in the size. They are big, beefy tires (8 PR). Each (new) weighed 30 lb in my bathroom vs the Goodyear Marathon (used) that weighed 20 lb.
There is a lot of tire discussion over on the Casita
Forum. It seems the Kumhos were the favorites for a long time and then folks started having problems with them. As far as I know, no one has reported trouble with the Maxxis (knocking on the wood-like surface of the table).
Commercial or truck tires may be the best choice for some trailers because no ST tires are available in the required sizes. Some, if not all Airstreams use LTs for this reason.
