Car Trailer Tires

I work for a major boat trailer manufacturer in Florida we have used various brands of tires, first off stay away from carlisle not a very good tire,second never ever run a tire made for a car on a trailer the side wall rating is not heavy enough,goodyear,towmaster,loadstar,kendra radials/bias ply,all have been used by us, all have had warrenty claims but nowhere near what we had with carlisle in total. Sun and air pressure are key to tire life. Thats my two cents worth happy hunting.
