Servus together, I’ve seen the Michelin Alpin A5 in size 245 / 50 / 19 105V since last winter. When I was washing the car after the holiday I noticed bubbles on two tires. We can’t remember ever having driven over any obstacle (Bordstein or the like). The tires are almost new (max. 6.000 km). Has anyone ever seen this in the form? (I don’t) Thanks in the round!
