Hopefully you can see in these pictures, something I've not experienced before - tyres that have cracked, I'm guessing as he car as stood a lot. They are 6 years old but have only done 13k miles. I'm going to replace them, but curious whether people think I am wasting money or should get them changed asap?
Cheers

Sooner rather than later, the only things that keep you on the road are starting to fail.

Imo they arnt the worst, I think it would depend how much mileage you do, you could get another year or 2 out of them imo before issues occur.

Although cracking is a sign of the rubber going brittle, so the tyre will be less effective.

Bin them.

You sure they're only six years old? They might only have been fitted six years, but they could well be older. What's the DOT date code on one sidewall?

The car is 6 years old so hopefully not much older. It has not been used much as they are on a Clio I bought for the kids to learn in and the oldest went to Uni before she passed her test. My 18 year old son has now passed and is using it - I'm going to get them swapped asap, only noticed it recently.

Tyres have a 5 year shelf life, hence having the week they were produced printed on the sidewall.

I had 2 sets of Contis do this within 18 months, Continental came out to look at the second pair and took them away for analysis, the result came back as "Left out in the sun too long".
It's a fkking car!!!!

If this is a safety issue, why not an MOT failure?
The tyre pictured is not as bad as the cracks in the tyres of my wife's car.
She doesn't do a lot of miles - just travels a few miles across the city to work a few times a week so they've never overly bothered me.
I'm pretty sure they've been cracked for the last 2, possibly 3, MOTs but not even an advisory.
Having said that, definitely intending to change all 4 before this years' MOT in June.

I bought a car last year which had done very few miles in recent years, and the tyres look like that, but have plenty of thread. I asked at the MOT last month and the tester said to use them and change when the thread gets low. Not had any issues with grip (and I've done an autosolo on them so would have noticed!), and no MOT advisory.

What's the DOT age on the sidewalls?

Only an mot issue if cords are visible, those don't look too bad, but if the kids are using it change them perhaps. A 6 year tyre shelf life doesn't mean that is when they're done, just when can be sold as brand new other than new as I understand it currently. It is a good gauge having the date on the tyre though. I have 18 year old tyres on one car, cracks like above, not as bad as the ones prior, those had cord visible (these are a spare set I used) car doesn't get used, so not an issue.

Driven on worse for 10k miles. Did changed them eventually as I decided I was pushing my luck a bit going 80 miles on the motorway a day on them.

Ive done track days on tyres like that. It's only the very top layer, get him to do a few wheel spins and handbrake turns and they'll be good as new.

Take a few psi out of em then drive it on the door handles for half an hour or so. They just need a good pumice.

I think it's the UV component in Sunlight that causes rubber to start degrading like that.

It depends.

We don't all drive Evos / imprezas at 130mph everywhere.

Cracks on the outer tread are less concerning than cracks in the thinner sidewalls.

I used to be blasé and drove for many years in cars with cracked tyres - afterall they passed the MOT.

My old BMW 328 had them - one morning I came out and noticed a flat tyre - I went to blow it up and the sidewall had gone - the day before I was driving on it at 70mph !

Never again.

Six years is about the limit age-wise, according to the manufacturers. Judging by the wear I guess they're on the back rather than the front?

Thread ressurection.

I noticed the mrs car has a cracking on one tyre, is this a cause for concern?

Had an advisory on one of my cars last month for cracking on one tyre wall. Very fine cracks and had to look closely to see it. (And no, the test place was not one of those well known places that fit tyres fast, or at any other speed!).

It only appears to be on the actual shoulder of the tread, not the sidewall. Got to say it’s a tough one to call. If it’s used only round town I think it’d be fine. I’d have worries about prolonged motorway use.

On the subject of tyres and age I had perfectly good looking tyres taken off the OHs (rather fast) motorbike this week. Date codes 3804 and 4204. yikes She doesn’t ride it much....
