Seems to me old because of the numerous cracks. In my country it's a sufficient reason to not pass MOT, presumably in your country too.

 

There seems to be a few cracks on the where the tread plates fasten and that’s prob what they are failing on.
Not the scuffs on the surface.

Prob will see a lot better with wheel off.

 

Still fine i wouldnt worry
Read the date code ' eg 0920' means 9th week of 2020 they are made. as long as they are not over 10 years pold(they dont look it) it will be fine.
Normally they start to do that becuase of a 'harder' rubber compound. I've noticed Bridgestones and Hankooks to do this.. compared to michelins. you also get it with 'eco' tyres which have a harder rubber compound compared to other tyres

 

Yes Bridgestone tyres have fine hairline cracking show up quite early from new , i blame high power jet washing at your local hand car wash. It chases away the detergent in the tyre carcass.

 

Nothing wrong with those at all , mine are quite bad for cracks on the edge but still passed the MOT without issue.

 

Her car has GT Radial tyres cracking in the tread groove they are 2 years old manufacture code. Passed mot had it checked at a different tyre place and he said they were fine

 

I have Pirelli tyres on my car dated 2019, and they are more cracked than that in the same place. I'm going to get through this winter then replace them.
They didnt fail an MOT, and have around 5mm of tread still left, so dont want to bin them too early.

I have had many problems with Bridgeston Potenza tyres in the past, they actually crack in between the tyre tread rather than the edge which seems far more dangerous.
Having said that, I had matching Pirelli's on the fronts too which ended up cracking loads.

I dont think Pirelli are that great either!

 

If they're cracked they're dangerous. Bin them.

Get new Michelin's for winter. Their new v pattern tyre is actually very good new technological advances 8n the tyre compound theyve learned while developing tyres for the Bugatti Veyron. And they're cheaper than the old technology used in the Pirelli

 

A little surface cracking does not matter, as long as the ply & cords are not exposed.
The strength of the tyre is in the ply & cords, not the outer covering.

You would be correct if they still used cords. Modern composite steel belt tyres the rubber is an integral part of the tyre's safety. I have tested this to tyre destruction more than once. The cracking means the tyre is past its designed service life.

 

Oh yes these tyres are also economic and eco-friendly as they've got low rolling resistance. And can handle the hotter summer weather too

 

i would say so once the rubber shows signs of cracking it can disintagre prety quickly and lets face it is your only conntact with the road and safety hope this helps

 

Go tell that to a farmer lol, I know what he would say plus....

I have first hand seen 20yr old tracker tyres perished and still going strong and being use on the road / land...

If you had a fast sports car / hot hatch and do a lot of driving at high speeds I myself would not risk it

 

apparently the cracking is caused by the vehicle standing around for long periodes as i was told

 

The preservative detergent falls away & settles to the bottom of the tyre if the vehicle is standing & not being used. When the tyre rolls along the detergent is dispersed around the tyre evenly nourishing the rubber. High power jet washing is bad for tyres as well as it washes the detergent away. Bulges , big splits in the tyre sidewall is a safety issue but fine cracks is not a reason for failure.

 

 

A Guide to Cracked Tyres: Everything You Need to Know


10/01/22


While some cracking between tyre treads can be a sign of wear and tear, larger cracks may be more significant and must be dealt with, especially if your car’s MOT is due. Read on to learn more about cracked tyres and how to know if they’re a problem or not
What Causes Cracked Tyres?
The rubber on your tyres is held together by special polymer bonds, allowing the tyre to be flexible yet strong enough to hold the weight of a car. Cracked tyres occur when these bonds break down. This break down can be caused by:
1. Bad Weather
The polymers in your tyre rubber can expand and contract with extreme heat or cold, which can cause them to weaken over time – this can lead to the tyre cracking between the tread.
If you’ve been driving in heavy rain or snow for some time, water can end up in small, pre-existing cracks, making them worse as the liquid freezes and thaws with the changing temperatures. This can also happen when standing around for long periods in all types of weather.
2. Rubber Breaking Down
Because rubber is a naturally occurring material, it degrades over time. This can be why cracks form in your rubber tyres. With the longevity of natural rubber in mind, it’s a good idea to replace your tyres roughly every five years, even if your tread is unworn.
3. UV Rays
UV rays are powerful and can speed up the degradation process, especially if you don’t have indoor parking.
4. Under or Over-Inflation
If there’s not enough air in the tyres, it can cause more friction on the road as more of its surface gets exposed to the tarmac. This can cause it to wear down more quickly and develop cracks. On the other hand, if a tyre has too much air, it can put unnecessary pressure on the tyre wall and cause it to bulge. There is a lower risk of getting cracked tyres if you regularly check your tyre pressure.

Are Cracked Tyres Dangerous?
When tyres are visibly cracked, it means that the strength and structure have become compromised. If you choose to drive with cracked tyres, it may lead to a blowout and/or having to change a wheel on a busy motorway, both of which can be dangerous. Small cracks are usually less of a worry, but it’s important to monitor them to ensure that tyres are kept clean and dry so that rot cannot set in and make them worse.

Can You Fix Cracked Tyres?
The experts at ATS recommend that you don't try to fix cracked tyres yourself. This is because cracks permanently damage the structure of a tyre so, it can’t be restored. However, ensuring your tyres are inflated – as well as being kept dry and clean – can prolong their wear and lessen the likelihood of cracks developing. Parking in a garage or a shady place can reduce the chance of cracked tyres too.

Are cracked tyres illegal?
The condition of your tyres can potentially land you with some hefty fines and points on your license. This includes not having the correct tread depth but also includes the general condition of your tyres. If there are cuts in excess of 25mm or 10% of the section width of the tyre, or if there are lumps, bulges or tears caused by separation or partial failure of the tyre structure your tyres could be considered illegal.

Are Cracked Tyres an MOT Failure?
If your tyres don’t meet the legal limit for tread depth, or if they have any tears, bulges or cracks in the sidewall, your vehicle will fail its MOT. So, it’s important to get your cracked tyres replaced at the first sign of any damage.
Think you might have cracked tyres? Why not come and get them checked by the experts at your nearest ATS Euromaster.

When to replace cracked tyres?
If you see cracks in your tyres you should generally get them replaced. Once cracks start to appear the structural integrity of the tyre is compromised which can lead to a tyre blowout. If this happens when you're driving and speed this can be extremely dangerous.
If you continue to use your tyres it's likely the condition and cracks will only get worse over time. If you are unsure if your tyres need replacing book in for a free vehicle health check and our technicians will be able to review the condition of your tyres and advise on the best course of action.

False information.
Nowhere in the MOT testers manual does it mention cracks in the tyres, unless they are deep enough to reach and expose the ply or cord structure of the tyre.
But of course, ATS are in the business of selling tyres, aren't they?

 

I've always thought that a car should be able to pass an MOT at anytime?
Very poorly thought out advice.

 

I read a very good book on travelling around the world by Land Rover, and two things were remembered, never run on alloys, they are not so strong as steel or as repairable, and the Michelin tyres available then were less succeptable to cracking than most other makes in hot sunny climates. That said, my only MOT failure was for slight cracking of an 18 month old Michelin radial fitted to a motorcycle.
