Looking for some advice from the K team here - while checking my tires before the ride today, I noticed about an inch long crack on the inside tread of my Metzler tires. It seems to be a tear/rip of the rubber - not a gash from road debris.
Could this be a defect? Poor tire pressure (i'm meticulous about this)? Should I be concerned? Should I replace it? It's less than 5,000 miles on this tire.
