Would You Replace These Tyres?

Let's say you have a 14 year old car with low kms for the age (e.g 70,000 km). Two of the tyres are original (run flats), the other two were replaced. One tyre replaced 8 years ago and the other within the last year.

Given that the 50% off All Pirelli Tyres deal is coming up, would you replace any of the tyres (and which ones) even though they are still fine?

Are Pirelli tyres considered good tyres?

Edit: Checked the tyres and unless I've misread the manufacture year, the actual age is different. Two tyres are 8 years old, another 12 years old and the last less than a year old. I will be replacing the tyres

        DOM doesn't work, rubber gets attacked by ozone, they degrade even sitting unused, some people are in denial without hard facts.

    Tyre degrades over time and I would not play with safety by using a substandard, old, or worn out tyres.

    Really depends on the vehicle. If it's RWD I'd prefer the old rubber so that you can break traction a bit more easily when you want to kick the back out a bit.

    Heres what you are going to do - You are going to replace them all; and in 7 years time, you will replace them all again.

    For a second I read your username as “this username is mistaken” and the post made sense.

    I'd say it's kind of like trusting a 10 year old condom.

    Just get them replaced and be at peace.

    For the love of God, replace those tyres. I'd expect the comments are littered with people advising that the rubber compound goes bad over time. I would think any tyres 5 years old need to be replaced irrelevant to tread.

      Cheers. Thanks for the video. I will be changing the tyres

  • mini2 on 20/11/2023 - 14:11

    Replace the 3 8-12-year-old tyres, but then, you run into the problem of tyres with different tread levels…

    • thisusernameistaken on 20/11/2023 - 16:02

      Even though the 4th tyre was recently changed? Can't have worn down that quick, could it?

    There are so many people here commenting who know nothing about tyres. Every manufacturer, even of motorcycle tyres says that 10 years is acceptable. They say that you should have them looked at by a professional after 5 years to look for damage, cuts etc. Not one of them says that tyres over 10 years old are dangerous and must be replaced. Michelin even says that tyres are new until the day that they are fitted, which can be 6 years after the date they are made. Vic Roadworthy laws can fail you for having brake fluid that is too old, as it can be tested. If the age of a tyre was unsafe, it would be a roadworthy and safety item. Plenty of motorcycle magazines have tested old tyres around racing tracks and found that their performance was no different to a new tyre. They tested the softness and found that the rubber was nearly the same as the new tyres. This is because tyres are no longer made from just rubber. Chemists have come up with additives and synthetics that mean that tyres do not behave the same anymore as older tyres. In some cases, tyres are completely devoid of rubber, being all synthetic. If anyone has ever used stock racing tyres in a category, you would know that you can have the tread shaved down to half (less movement on the blocks in the tread) then have them baked in an oven at high temps to change the chemical characteristics so that they grip better. The extreme heat doesn't cause the rubbers to crack because it's no longer just rubber. Its chemistry.
    Here is a simple article from an Australian tyre seller. If you bother to do research and ignore the marketing claims designed to sell more tyres, you will find heaps of info. And for all those who downvoted me before, my workshop fits and sells tyres, specialising in Euros and Exotics. I've done training in the area and been involved with companies who want to recycle tyres but are hampered by the fact that they are no longer just rubber, and therefore do not behave the same when it comes to recycling them.

      No professional is going to tell anyone that a 10 year old tyre for high speed road use is acceptable. Professional is there to make some $$$ and give their customers peace of mind. If you dont then you are a honest shop tyre fitter far from being a professional.

      Since you work in a tyre shop who knows tyre compound secret formula, Would you buy a new old stock 5 year old tyre or would you fit this tyre on a customers car? I know I would be surely pissed if I get fitted one.

      Finally, why are new tyres nicer supple ride than old tyres?

        A tyre is new if it has not been sold or used, regardless of the date it was made. As Michellin says, even if it was made 6 years earlier, it is still a new tyre when it is sold, and any calculations as to age start from the date it is sold. Tyres are not milk. They do not expire. So if you buy a tyre that was made 6 years earlier, and you still have that on your car 9 years later, Michellin says that is absolutely fine.I would accept the say so of one of the worlds largest tyre companies over your opinion anyday.
        New tyres ride better because when you get them fitted you are replacing old ones, which will have wear and most likely be at incorrect inflation. It's normal practice to have a wheel alignment done when new tyres are fitted. That's why you notice it.
        And I don't know any secret formulas. I do know that tyres used to be made of rubber and steel. Now they are made from rubber and other compounds, or even totally synthetic compounds. This isn't a secret.
        When you get a roadworthy done, nobody looks at the date that the tyre was made. They look at the tread, wear and for damage and cracks. They couldn't care if your tyre is 5 years or 10 years since the date it was made. And that is from professio9nals, not tyre salespeople.
