The sidewall of one of our Kelly Tires Safari A/T LT275/65R18 fractured. I've never seen this before on a tire and I've purchased a ton of tires over the years. Kelly is made by Goodyear but they are not the same quality. The tire was in use for 9 MOS/approx. 15,000 miles but I've never seen anything like it. We rotate our tires every 5,000 miles and I mention that because the front tires at the time we got rid of them would have only been on the front 10,000 miles and they wore very unevenly. For comparison, the Nitto Ridge Grapplers that replaced the Kelly Tires have far less wear wear at 10,000 miles than the Kelly Tires did. But the main concern was the fractures. Something about the way Kelly Tire made this tire was seriously wrong and personally I would never buy another set of Kelly Tires.
