Do I need to replace my front tire?
Okay, so I road for a while this summer without checking my airpressure in my tires (DOHHh!) and When I finally checked the pressure once the cold snaps started, the front was down at around 26 PSI. So I look close at the tire. The treads are still pretty deep, not balding at all yet...(maybe 50% of the height on the side treads that don't take as much of a beating, the line through the center of the tread)...However, I did notice fine hairline splitting occurring between the tread patterns, right in the 'canyons' of the treads. Not huge splits at all, but fine little splits starting. Do I need to replace this tire? I mean, its loosing no air, no traction loss, still a lot of tread...just the hairline splitting thing...does this mean the tire could fail on the highway?
