I just changed my tyre (Bridgestone)last year and it was flat this morning after the car landed on irregular ground. The NRMA guy helped me change the tyre temporalily. Because I just changed my tyre recently and it is very good quality, I just want to fix it rather than to replace with a new one.
I live in eastern suburb. Can you recommend a reliable mechanic?
