Enclosed car hauler...

Whatever you get I would strongly recommend you invest in a set of Carlisle trailer tires. I had numerous blowouts on my 28' enclosed with several different brands until I switched to Carlisles. No problems on these tires in the last 2 years hauling 2 to 3 times a month to racetracks.
I have those on my car trailer. Have had 2 blowouts. Had 4 tons of pellets on the trailer. Thanks to not paying attention I had to go around the back of a strip mall...and had to climb a curb at 30* angle. Both tires on that side blew out, one the next time it had weight the other when I was empty going about 60. Got them from Discount...with the certificates...
