I've had it with cheap Chinese trailer tires!

I sell tires every day for a living. I havent seen a 15" (or for that matter 13" or 14") trailer tires in the last 6 years that was made in America. The best trailer tire that I have ever been associated with is the Hercules Power STR. Unfortunately we no longer carry them but they held up better than any trailer tires we have sold and I can give you a list of 15 or more that we have tried. Right now we are carrying a tire called summit and it is junk! I agree with the above about the poor quality of the Carlisle. They used to have a good tire but since being ship over seas they are now junk. As for a 10 year warranty Im sure you can kiss that money good bye because trailer tires have no warranty except for manufacture defects and we all know how that one plays out. Heres the key to make them last as long as possible: Make sure you carry the correct air pressure as when low they build up to much heat, also do not over load beyond the tires load capacity and make sure the load is centered on trailer to your axles. Even when following this, trailer tires still fail way to often.
Best of Luck
