Any tyre brands out there that don't crack ? These "mid range" Avons are only 5 years old - and have 5mm of tread left :





And this Dunlop is 9 years old. New tyres all round then...? What say PH ?

I have six year old Michelin’s on my car. 43k miles covered, 4mm remaining, no cracks.

The mother has a 2 year old A4, 12k Miles covered, Hankook tyres, full of cracks. Appalling.

I don't think many tyres will reliably last more than nine years, especially if the car is kept outside.

They shouldn't be cracking that much after five though, that's a bit crap. The Eagle F1s on our Skoda have no visible cracking at six years old (although one of the sidewalls has just failed, resulting in a big bulge; whether that's age or one of the many potholes which appeared last winter, I don't know).

The tyres on my MGB were 20 years old when I got rid of it and still looked absolutely fine, although it had been off the road and in a garage for most of that time. I can't remember what brand they were though. Might have been Dunlops.

All four of my Michelin PSS have cracked, loads of meat on too which is annoying, and they’re a silly size so expensive! 205/40/18

Dunlops and Yokohama tyres seem the most common for this.

It is not an issue initially but is usually down to lack of use for many tyres. Around 6 years old anyway i would think of replacing them, check the dot code for the week and yesr of manufacture.

Dont forget for some sizes that they could sit on the shelf for a while. I mean one my replacement front tyres was 6 months old before it even got fitted to my wheel, some can easily be a yesr plus!

If I'd only used two or three millimetres of tread in five years I'd consider using taxis instead of owning a car!

Tyres have a shelf life of 5-6 years.

Ha ha, yes not my car belongs to OH

She does some miles but doesn’t exactly push it to 9/10s.

I couldn’t believe it, I’ve never needed to replace tyres before 2mm in my life, and they certainly don’t last anything like five years smile

She won’t be buying any more Avons...

Michelin had a little marketing campaign earlier in the year stating ten years for their tyres with no drop off in performance!

Yeah, interestingly Michelin recommend yearly visual inspections from five years and replacement at ten:

Most other manufacturers seem to recommend replacement at five.

Blackcircles have a policy on how old tyres can be and they can still call them new. It's 5 years. Yes, a tyre up to 5 years from date of production is sold by them as new

This seems to happen more and more in recent years, had a couple of Pirelli's that started cracking even though they wasn't that old. Are the tyre companies up to something?

Yes, they're obviously conspiring with each other to make all their products worse.

There's a known problem with Dunlop Sport Maxx fitted to Jaguars that look exactly like that one in the photo above, so much so that a lot of them have been replaced FOC.

Yes probably because tyres are under more stress than ever personally speaking.

More extreme temperature changes, lower profiles, manufacturers wanting more specific variants of a variant in some cases it goes on and on.

What I have noticed though is my Dunlop Sportmaxx GT's only start with 7mm, not the more common 8mm.
