Hi All
Thanks John for restarting this thread under the relevant title. I am re-posting here my information.
Your original post caused me to check my tyres carefully in advanced of a continental holiday, and I found cracks around the junction between the sidewall and tread. My dealer took one look at the tyres and advised me to change them - I am planning to fit Firestone. He had come across several other instances of this with 2006 Swift caravans.
My email to Swift on Matador tyres elicited the response: "Following recent consultation with our tye supplier it has been established that in some instances between the DOT range 40/05 through to 46/05 the tyre side may develop sidewall cracking". They did not respond to my question about any recall. I believe the 'DOT range refers to the date of manufacture of the tyre, which is shown by four figures on the sidewall. Thus 4005 means the tyre was manufactured in the 40th week of 2005.
In fact my tyres are 4905, which is outside the range quoted by Swift. They are size 205/65/15 fitted to a Challenger 480, delivered in April 2006.
I will be pursuing Swift for a warranty claim, but this raises a much more serious issue as to why there has been no publicity elsewhere for a vital safety critical issue.
If I had not read your original post and then checked, and one had blown on hot French autoroute.....
Thank you John for the alert.
Keep Safe
