My summer tires were dismounted yesterday for the winters to go on, and the installer noticed that my rear tire had the beads ripped in two places, both strips about 10 cm long. I watched when he removed the tires so it wasn't from dismount.

I do some DE days with my summer tires but nothing else. Haven't hit any curbs or potholes. THese summer tires are new and went on in July.

Can anyone tell me how this can happen. My initial thought is this must have happened on install?

THanks
