MOT: Cracking around edge of tyres

Probocop · Post by **Probocop** » Wed Jun 05, 2019 11:57 am

I've got an MOT due pretty soon, and I've noticed some cracking around both front tyres. Judging by the mileage on the past few MOT's I think these tyres have probably been on a fair while...

Reckon this would be a fail?

Wouldnt imagine it would be an MOT failure, however if that were my car i'd take it as a sign the rubber is way past its best and starting to degrade.
A sports car like a Z4 rubber makes all the difference, maybe time to start shopping for new tyres?

Oh yes - they will definitely be replaced (probably with a set of PS4's), however the MOT due date took me a little by surprise, and I'll likely not get chance to replace them first!

I reckon you'll be fine with an MOT - depending on the place it might not even be an advisory!

though that said, how old are the tyres? they'll have a week and year date stamp on them somewhere. if they're older than 5 years I'd look to get them replaced.

Hi, as far as i know it’s only a failure if the cords are showing

I can't see them getting you a fail, but as you say it's probably time they got changed!

Good luck with the test.

As others have said it will probably be an advisory providing there aren't any lumps or bumps but personally i would throw them out!

If the MOT station does fail you then they will be doing you a favour in forcing your hand to be safe.

Are they Vredesteins? I had them on a Disco3 and they deteriorated in the same way - The outside edges of the front tyres also started to wear- the geometry was perfect but it seems the unusual wear pattern was also due to that same deterioration/breakdown of the rubber composition.

Do you know if the mot can he failed on tyre age...checked my tyres on my Westfield and the Avon CR500's were manufactured in 2003

Thanks for all the replies. It's booked in for an MOT on the current tyres, but I'll get them replaced soon

Yup, they are indeed both Vredestein. I'll likely go Michelin next time.

From the gov site,

2.12 Tyres and wheels
These will be inspected to check for:

condition
security
tyre size and type
tread depth
Spare wheels and tyres are not inspected.

Vehicles first used on or after 1 January 2012 will be checked to make sure the tyre pressure monitoring system (TPMS) MIL is working.

Will pass no problems IMO... don't even think they'll come up as an advisory!

Most manufacturers' recommended maximum is 6 years, not 16.

I don’t think they would fail it for that, the inspection is based on condition not age

True, Rob.

For what it's worth, though, my experience of old tyres is that they not only decay at the edges, but also crack between the treads. So, you're driving round on rubber compound that, when it fails, fails 'catastrophically'.

Put another way, who'd want to risk their lives on crappy old tyres anyway?
