had the Zlines for approx 6 months. wear is average, noise is odd - they make strange noises over certain surfaces and rumble a lot when parking or slow cornering with a mid-to-high amount of steering lock.
visited a Blackcircles approved garage yesterday,as one tyre is slowly loosing pressure, no bug deal, new valve. however, garage noticed the tread separating from tyre body on all 4 tyres.
i am careful to check pressures on a fairly regular basis and the car has done 80K miles, is now 5yrs old, so not a dog of a car by any stretch.
anyone else had problems like this?
the returns and complaints procedure is woeful in the uk. you have to send the tyres back for the manufacturer to confirm the cause of fault, which can take up to 12 weeks. in the mean time, you have to buy new tyres if you ant to drive the car, and if for some reason they do no uphold your claim, you then have 2 sets of tyres...
also, if your claim is upheld, a refund based on remaining tread depth is offered.
