My tyers went flat and towed to their shop to fix, they changed both of the front tyers, after a week one got abubbles from the side, l showed that to few mechanics and they all were agreed that the tyer must be faulty( which they have warranty with this fault) or when they were instaling it the installer cut it from inside, they recommended not to drive it and go back to them to fix it , as it must be their fault n wrong installation, and they must tefund or change it for free. But they ignored with silly explanation and they even asked for paying again even for higher price!!! Btw l will take that to fair trading and l ll claim full refund for both the tyers as if l want to change one l ll have to change both tyers and l dont trust them to do it for me.
