When I had my Falkens taken off my steel rims and mounted to my fuchs for AXing one tire had a small chunk missing from the bead. The tire holds air just fine, I haven't AX with it yet but I don't think there will be and issue. But...... I have a spare rim that I want to mount another "new" Falken on. I was going to order a new tire from vulcan tire but looks like the new Azenis sports have a different tread pattern from the ones I have from last year. Will it really matter if the tread pattern is different? its not much but it is different. I only use these tires for AXing.
