Hi all I've had nothing but problems with GoodYear F1s on my 2006 TDI S-line. The rears went like a 50 pence pieces because their not suitable for rear multi link. This made the car sound like a washing on spin going down the motorway. Audi told me not to find them to the A4. Then I replaced my brake discs today and took both front tyres off and found them like this ( see pictures below ). I have returned the tyres to the supplier and they are taking this up with GoodYear for me. The cracks are down to the wires of walls and all over the tyres inside and outside walls. Funny thing is, Audi MOTed by car 2.5 weeks ago. The tyre company think the tyre is faulty and have seen this before on very cheap tyres. They think the tyre couldn't take the weight on the car. Must say driving down the motorway each day on tyres like this makes me feel sick..but glad their off now.
