Had a fairly similar experience to Jess B Took my Commodore there to have a slow tyre leak looked at. My car is not fancy, just a bog stock Executive Commodore with standard 15 inch steel wheels.
Parked the car, waited a while, told him I had a slow leak, guy says we may have to put new tyres on, I say I only wanted the cause of the leak fixed, anyway he jacks up the car, removes the wheel, tells me again I need new tyres, I say they are perfectly roadworthy (they are and I check them reguarly) and he takes an eternity to fix up the tyre and refit the wheel.
They will not get the tyre replacement job when they do come up for replacement, thats for sure. read more
