Haven't posted in a long time. I have a new set of tires on my ram 2500, (LT265/70-17) and the front passenger side tire is developing cracks on sidewalk all the way around with only 300 miles on tire. They look like cracks in surface rubber only and about 1" from tread, rest of sidewall ok. Pressure is at 65 psi. Date code of tire is 4118 which is as fresh as can be. Never seen this before. Was purchased at Walmart TLE and they were very good at replacing it. Any ideas from tire experts on what could have caused this. Tire balanced and rides nice no other symptoms other than cracking. Three other tires look great.
