Tyre cracking

The Pirelli scorpions on my 2016 car have developed some cracking as per photo. The tyres seem to be from a 2017 batch. It passed the MOT a few weeks back and tread depth is 4-5mm. Worth changing sooner rather than later? Haven’t seen this on a tyre before.

Kind regards, Peter

I've given up with Pirelli. Not very good any more.

And yes, get them changed before they break up during driving. Their useful life is behind them.

I'd change them immediately.

If they are all like that (& the defects are all round the tyres) I'd keep the old ones & take it up with Pirelli.

When I had an issue with Pirelli tyres, they were very interested and even went so far as to say they would arrange for one to be sent to them.

What 7yo tyres. That is typical of tyres that have been out in the sun all day over a seven year period .

I concur with most. You got your monies worth by having 7 years with tires. Not to mention they are severely worn and probably hydroplane easily now.
Get on with it and replace them so I don’t have to read a thread about a mishap when a tire blew.

FWIW, I replace 2 sets of tires on 3 vehicles nearly every 5 years. I wouldn’t take the chance.

If they are perished enough to crack, they are probably brittle and certainly not worth the risk.

But, oh the envy of having a 2016 D4 with low enough miles to be on original tyres!

You could have the vehicle parked up when someone runs into it. Once the insurance assessor spots the tyres you will be uninsured and there will be no payout. Police will have same opinion and will probably send you to court.

It is very unfair with caravan and trailer tyres that must be replaced within 7 years of manufacture even though they could have done very limited mileage and have virtually no wear.

Thanks for all of the advice, which I will definitely heed. I’m feeling very lucky that nothing happened on my way home on the A1M last night at motorway speeds. The car will stay on the drive til until it’s sorted next week. I managed to pick up a brand new 20” style 510 alloy a few weeks back that was going cheap and I had a new Pirelli tyre fitted. It’s a genuine grey/diamond cut wheel rather than the usual black/diamond cut but will be ok for the time being. The spare wheel/tyre is good too, so I’ve got an immediate solution that will allow me to drive the car. I’ll then get the two original alloys refurbed as there’s a bit of alloy corrosion, plus add new tyres and I should be all good to go again.

Thanks again for the replies and advice. It’s much appreciated.

Peter

I have covered considerable miles using trailers (all twin axel) and only ever had to replace tyres that had actually worn out on one - an IW dropside which had 10" wheels and I used to get around 7/8k out of a set.

Other trailers have suffered cracking (from UV exposure on one side only) within about five years - replaced & rendered unusable as soon as cracks appear.

That is not strictly true. Insurers can only refuse a claim if the defect has a direct bearing on the incident. They can however withdraw cover after settlement due to failing to maintain the vehicle in a safe condition and in accordance with manufacturer guidelines.

Drivrs are assumed to have little knowledge on the technical aspects of their vehicle so we are expected to follow the handbook. From the D4 owners manual

"All of the vehicle's tyres, including the spare, should be checked regularly for damage, wear, and distortion. If in any doubt about the condition of a tyre, have it checked immediately by a tyre repair centre or a retailer/authorised repairer."

The manufacturers guidelines are tyres should be good for at least 7 years and after that point should have regular inspection and replaced after 10 years even if they appear undamaged.

I bought a 20 year old Motorhome some time ago which had the original tyres on the front (and some awful far eastern balloons on the back). Most of the boundary between the tread face and the sidewalls had a fine crack all the way round so had to go. The spare however lived up inside the skirt of the motorhome and never saw the light of day so was absolutely pristine, evidence that it is primarily sunlight and more specifically UV that causes deterioration.

We had to change the tyres on our horse trailer simply because the sidewalls had deteriorated thanks to UV exposure over time. Tread, etc., was all fine otherwise.
