They are Carlisle tires. No idea if made in China or not, I'm not at home now so I can't check. Again, they looked to be in fine shape, no evidence of cracking anywhere except the one location where I suspect it was leaking from (on the tire that didn't blow). Without knowing the age of the tire, I (and guessing most people) would have never hesitated to use these based on the appearance. And yes, tire pressures were good, checked prior to leaving the lake.
