the set of 38" SXs have the DOT numbers cut out of the sidewall, they sections missing are about 3/8" deep. He cut them out so he could get them warranteed he said, cuase the sidewall tread had little cracks in it, so i guess he had to send those numbers in and they would warranty them. Does anyone know if it would be a poor decision to run these tires, i use it on the trail and as a daily driver. Im just wondering if they are safe.
