Doesn’t look like a cut to me either, looks like a defective tire, I had that happen to 2 different rear Avon Cobras on my Goldwing, I will never buy another Avon tire.Looks like a crack, more than a cut. Weird.
My garage, (which is below 2 bedrooms in my house), in Victoria, BC gets really cold in the winter. Yeah, right.Seems to be a fairly common problem. Over the last 10yrs or so I've seen quite a few similar mentioned on forums on different brand tires. Not a cut, but a crack.
One guy on a goldwing some years back had similar looking cracks, a bunch of them, on a rear tire. Can't remember the brand, but when he contacted the company asking about what happened, they said the tires got too cold. I guess they expect you bring your goldwing in your bedroom all winter so the tires stay all nice and supple for next year.
Just what Yamaha recommends, 42 PSI. I ride mostly on the street, rarely go off road.What pressure was in the tire? I see what looks like blue tint at the top of the crack.
What can a blue tint indicate?. . . . I see what looks like blue tint at the top of the crack.
Heat.What can a blue tint indicate?
My sister lives in PHX and carries a hot mitt (like for baking) in the car.Makes sense. I've seen some on my tires, just not as dark. But, this is Texas, so. . . . plenty of heat.
I used to live in the Tri-Cities (Richland-Kennewick-Pasco). Hated the weather. . . . and that part of the state is called "the desert part". After living in Page AZ, a real desert.. . . . That is why I live in seattle lol.
Interesting. There were times I was riding it hard last summer during the heat, having my feet touching down and having the traction control light flickering around corners.Heat.
Note the bluing on this tire at a trackday:
