Worth speaking to tyre dealer, but what was the date of manufacture on the tyre?
I've seen this sort of thing before and tyre manufacturer said it was because the tyre had passed its six year life. Until that point I didn't realise tyres has "best before" dates..... Apparently it's something to do with chemical breakdown inside the compound...... Hence all tyres have a date mark on the sidewall..... It is normally a week number (2 digits) followed by a year (2 digits) and normally appears slightly different moulding from the size etc..... So may be something like 4209..... Week 42 of 2009
