Took car to garage 2 weeks ago to replace drivers side front tyre due to low tread. They said when they looked the front passenger side tyre was also low tread so they replaced that one too.
about 4 days later the engine warning light came on for low tyre pressure. I checked them all and front passenger was at 30psi (should be 36) topped it up and reset thought maybe it was a bit low when it went on. A few days later it happened again, checked levels and it’s at 30 again. Topped it up and rang the garage, no answer so
left a message asking for a call back. Didn’t hear back but a few days later it happened again, I rang garage again they answered and said bring it over.
When they looked at it it was damaged inside (like scratch marks) and a lot of rubber had been burnt off. It was unusable.
They acknowledged they hadn’t sealed the tyre properly causing it to lose air but have said i must have been driving it flat to cause the damage so it’s my fault. At no point has the tyre been flat and when it lost air it was topped up immediately. It also doesn’t get driven a lot, every couple of days locally.
The tyre was only on 12 days.
is it my fault or the garages? Who should pay?
