I was having a lot of trouble with the 15" 205 Goodyear Marathons and my local tire store convinced me to try a chinese trailer tire that they had sold many of with no complaints. Currently I have removed all Marathons and have 4 Chinese tires on my 20ft enclosed. The last trip we made I checked the tires every time we stopped and they were barely warm where the Marathons were always hot. Hopefully these will have a decent life. They're cheaper than the Goodyears also.
