My bridgestone RE040 are showing some strange signs of wear. Cracks have appreared in the tread grooves on all 4 tyres, which extend around the entire tyre. The tyres have just about done 5000 miles in the last 10 months. I have mentioned this to my dealer when they repalced my corroded alloys (which lasted 10 months before the dreaded corrosion started). They have taken pictures and will speak to Bridgestone about the cracks.

Has anybody else had this on their bridgestones?

I have experienced the same problem on my dunlop sp900 lexus tyres. I notified dunlop and thet told me to get them inspected at my local agent. At the agents, several fitters looked at them and all of them had seen nothing like it before!! I have just come back from having 4 new tyres fitted and the old ones have been sent back to dunlop for inspection (all of which were still legal). I am now awaiting a response from dunlop and hopefully a nice cheque also.

Just thought i'd update you. Got home from work today to find a Dunlop envelope on the mat. Opened it to find out they were very appologetic and are refunding me 40% of the value of the 4 tyres i bought.

Good customer service Dunlop!!
