Tyre age

[Pincher]

I’ve got some wheels with what I know are pretty old tyres but I can’t quite work out just how old. Can anybody decipher?

Two are DOT N3FX and two are CXV5

All are Toyo Proxes T1R, if that makes any difference.

Age is moulded in week and Year look for 4 numbers in a rectangle with round ends.

[mcflurry]

There should be a four digit code to show the manufacturer's date.
The first two numbers indicate the week, while the last two indicate the year.
e.g. 1625 is the 16th week of 2025

Look on the other side of the tyre. IIRC T1r are directional.

It will (ought) to be written in the usual WWYY format

A couple of them (different DOT codes) look as though they have the 4 digit thing, preceded by a 3 character code. The other two don’t seem to have any kind of code at all!

One is AWA2206 and one is AWC3807

Guess the other two could have preceded that aging convention?

How old do people consider too old?

I'm on about tyres btw!

[Pincher]

I think that 2006 and 2007 are a bit too old!

That said, I think that tyres can be sold as new up to 5(?) years old.

For me, its obvious - they go hard. If they feel soft and compliant, and they handle fine, I'd keep them.

I had a TVR with very old tyres and it was undriveable in the wet. They were hard to the touch.

These may be on Estorils

Thanks. I need to check the age on them. I bought them in 2020 but they look good and the car handles well with planety of life left on the tyres, garage queen!

Timely.
I was going to swap my winter wheels for the summer ones, & found the summer ones have about 3-4mm on & are 10 years old.

3-4mm is okay for perhaps a few months, BUT 10 years is pushing it....plus we have a big-ish Euro trip in June.
It's off to Costco for a new set of 4

If you buy Michelin, there's a PH cashback code - unusually for Michelin codes it's valid for purchases from Costco.

Really?
I know their Bridgestone's are cheaper (generally), & have £60 off this month - the deals vary - but if you have a link handy, I might check.

I looked at this recently - there is no legal age limit for tyres on personal vehicles, only passenger and commercial (10 years, I think). I've had tyre shops wanting to replace very low mileage tyres on the basis that they are over 5 years old...

I've been replacing mine at 10 years, regardless of mileage

[LightweightLouisDanvers]

My dad has tyres on his trailer that are at least 40 years old

[Heaveho]

Interesting timing. I was out for a blast today and that very thought crossed my mind. I reckon the tyres on that car are circa 2016. Plenty of tread still on them due to the low mileages I do. I couldn't fault the performance of them, and can't see any cracking or visible signs of ageing. The tyres are Goodyear Asymmetric 3s and they're on a 400 bhp Mitsubishi Evo.

If I could feel the slightest deterioration in them, I'd replace the lot, as it's pointless knowingly compromising the handling of something like that, but as it stands, they'll be on for the forseeable. Part of the reason I like them is because of their powers of recovery after the car's been laid up for a long time, they don't go " off " in the way I've experienced with Michelins.

Ran a fair few T1Rs on my previous Griff, they cracked after a few years and never had confidence in them. The Nankangs I fitted to replace them were like night and day difference, highly recommended. Will be fitting a set to the other Griff.

I bought a V8 Westfeld with T1Rs and it span up in a straight line, in 3rd. Swapped them for R1Rs and it was night and day better.

Look forward to seeing it

Toyo put the tyre date at the end of a string of numbers. It’s there, but a bit hard to notice. See:
21770424 so week 4 2024
.


We put these Toyo Proxes Comfort on our Fabia. They came out reasonable in various tyre reviews, and were considerably cheaper than Continentals. As the car does about 5k gentle miles a year, they should be OK for the rest of a 13 year old car’s life. They replaced Vredestein Quatrac which developed a circumferential crack around the sidewall about 25mm fro wheel rim.

ETA: I change tyres at 6 years (in use) or at 3mm. Wet weather performance is most important to me.
