Bought 2x davanti 255/35/19 tyres on 5/3/19 done a few hundred miles on them.1 of them has ocurred a cut in the sidewall. Taken to 2 independant tyre garages to be told its a defect with the tyre no visible damage seen on the rim or tyre other than said cut. advised to contact the supplier who sell these with a guarantee for such issues. Contacted tyres on the drive to be told this is happening a lot recently by one worker. Next day got an email saying the cut was caused by either malicious damage or hitting a pothole really hard. This is without physicaly seeing the tyre other than pictures i sent to them. They can send them off to be checked at another £40 from me or i can by another tyre. I will be doing neither from this company
