I now have six trailers ,all types ,toy box, dump ,car , car inclosed , flat bed box ,and enclosed box , have all kind of brands of tires mostly new tires some problems with most ,but have had more trouble with Carlise trailer tires than with all of the rest , have been towing for over 40 years and more blowouts in the last 10 years than the first 30 years with much better equipment , no wheel bearing problems , but tires for trailers have gotten worse , and Carlise are the worse !!!
