Any - Avon ZV7 Tyre - Deryck

I have just failed an MoT due to two Avon ZV7 (225 55 17) fitted to the rear axle. Tread depth, etc was not a problem, but the cracking / tearing between the tread blocks had exposed some of the cords

Is this something to be expected on tyres two years old and 23k miles?

Of course its not. Unless stored in direct sunlight tyres should not crack for at least 5 or 6 years.

At 2 years old I would speak to Avon direct. I had 4 Michelins that had cracks at 4 years (not as bad as yours judgeing by your description) and Michelin organised ATS to remove and return them for testing. I received £193 for the remaining tread.

Only condition was they were under 6 years old. Just look for the date code on the sidewall.

Tyres were from Week 4 and Week 19 2017. I have sent a message to Avon to see what they come back with. I would have to recover the tyres from the garage but that shouldn't be a problem

Unless stored in direct sunlight tyres should not crack for at least 5 or 6 years.

Parking (or for that matter, driving) in direct sunlight would presumably be equally damaging, and pretty hard to avoid even in the UK.

That said, an MOT tyre failure due to cracking after 2 years, sunlight or no, is clearly a fault (rather than just cosmetic damage), and the manufacturer should, (and I'd guess will) compensate the OP for it.

I have just noticed that my two ZV7 are showing slight cracks at the bottom of the tread grooves after 13 months and only 5k miles! previous ZV5' had no problems.

I was told slight cracking is normal but the cords on mine are clearly visible - try deflating the tyre and pushing the sidewall around the site of the cracking to see how bad this is.

I have returned the tyres to the supplier and completed a form. I hope to hear back within a week or so. If my tyres were close to changing I would not have bothered, but I think I have at least until the end of the year before they needed a change at about 30k-ish

I replaced my Avons a year or two ago and noticed that the new set was made in Serbia, while the earlier ones were from UK IIRC. That may be a contributory factor?

No, the tyres were UK made - still waiting to hear back!
