Okay, I've got a safety question. I've listened to my front 90/90 Metzler tire rub against the fender while pushing it in a tight turn while parking in my garage for the last year. 5,000 miles with 3mm of tread depth still. Today I noticed the left side tire edge (sort of where the tire tread and sidewall merge) has worn down about 2mm or 3mm. Where the edge is forms sort of a '>' shape. The left side is leveled fairly flat now. The pictures don't seem to capture it, but I've added a picture from both sides for comparison. I'm beginning to wonder about having a sidewall blow-out. If you can gather anything from the photos, what do you think? Worry or don't worry?
