Continental Contact 2 ( 225/45ZR17)

This morning suppose to go Subang to fix my 50mm f1.8 lens. After i had my breakfast, i notice my car tyre flatten. What the.... F**k!....... So when to the near by Tyre shop to check it out... the answer i get is cannot fix.. have to change due to the tyre is cracked. Damn.
Ask how much the tyre... say they dun carry. End up, change to the spare tyre and drive to Taman Tun, Lim Tyre. They have the tyre... but RM780.... Damn,..... koyak my wallet. Anyway, things have to change.. means have to change lor... no choice. The final bill end RM860++, including balancing, alignment and workmanship... What a lucky morning. :(
