Carlisles ST's? Straight Up, Yes or No?
Replacing tires on 30' Cardinal tomorrow. Had decided on Cooper LT's. Having 2nd thoughts and really in a dilemma. Have heard so many horror stories about Carlisle, but also hear they have cleaned up ...

1. - most RV's (5'ers anyway) don't or shouldn't exceed 65mph "Very True"
2. - the ST tires are better suited for trailers (tread design, rolling resistance etc) "Marketing BS from ST tire industry" Go compare the tread of Goodyears high end G614 to their economy Marathon. The G614 has closed ribs that circle the tire, the Marathon has a tread that looks like a A/S tire with breaks in the outer ribs. The G614, XPS Rib and Durais R250 all have tread similar to long haul trailer tires. NO poly carcass tire will have a lower rolling resistance than a steel ply carcass tire like the three a named above. Also no open tread pattern tire like ST and A/S tires will have a lower rolling resistance than a rib tire like the three above
3. - E rated ST tires have higher load rating than E rated LT tires "True and based on the speed restriction, however this has not worked the well"
4. - ST tires designed for higher heat, and have heavier sidewalls for side stresses. "first part is marketing, second part is flat not true"
5. The bad "chinese tires" seem to be attributed to production runs from several years ago and most reputable manufacturers now build their tires over sea's and with much better quality control "ST have had issues way before production moved over seas"
Now for the biggest issue. Trailer manufactures are building larger trailers to the inflated ratings of ST tires and pushing them out to door with little or no over head in capacity. Additionally, ST tires quickly loose capacity each year in service due to loading. Third it is amazing that a niche product can be so over marketed.
