Continental CSC3

Ist set of Conti CSC 3, bulges and tears on the sidewall. Not even thinking that the tyre was faulty, I bought another set of CSC3's, 8 months later, the same problem. Switched to Pirrelli's , 4 years passed by and no tyre problems. still using the same Pirerlli's currently. Conclusion; Conti CSC3 is a ******* tyre and Conti doesnt even acknowledge that. DO NOT BUY CONTI CSC3 utter waste of money.
