Do a search. Carlisle tires suck. I have had numerous blowouts with them, radials and biased. I have had my trailer weighed and had tires with the capacity put on. A few trips later a blowout. Replaced it and the other one blew out. Just had a flat on another trailer due to a puncture and the brand new spare has flat spots in the middle of the tread. Just thought i would warn others of them. Anyone else feel the same?
