Look at this Michelin LTX. My all 4 tyres suffering from dry rot. Bought in 2020, seller said made in 2018 no issue, not like banana. Fast forward 2024, tyre looks like banana. Warranty doest cover. How to prevent from tyre popping?

If the vertical groove is not straight, that means the internal metal and nylon reinforcement broke. The only thing that could cause that is by running the tires over sharp angled surface like divider or metal bars.

Continental > all

In English or England several centuries ago if not half a millenium, 'dry rot' was a 'new' English word 'created' by carpenters then to describe external conditions on the surface of a processed wood exposed to elements like rain/snow and sunlight that has lost its structural strength.
This type of 'dry rot' wood was typically not advocated for continuing use or reuse.

Online info from tyre manufacturers and so-called tyre experts/practioners across the world always recommend replacement of a used tyre that has a so-called 'dry rot' phenomenon (as pictured above in post #1) i.e to terminate its continuing service -
implying a tyre with a so-called 'dry rot' surface or phenomenon has lost its structural integrity or structural strength.

Interpreting the so-called 'dry rot' tyre surface above as having lost for good its structural integrity/strength is imho without basis or facts, as rubber compound in NOT a load bearing (or structural) component unlike nylon/polyesters canvass or steel belts within a tyre -
It is a common recommendation or perception spread over the internet.

Hence, popular recommendation or proposal for terminating continuing service of a so-called 'dry rot' tyre pictured above is, I believe a myth and mistake - for the structural integrity or structural strength of this so-called 'dry rot' tyre is intact and is NOT lost as we are led to believe.

In a way I humbly concur with the seller and his statement, then on tyre age.

Thanks for sharing. But i deduced dry rot is hazardous and not a myth


According to the NHTSA, there are 11,000 accidents every year due to faulty vehicle tires. Worse yet, those accidents claim lives. In 2021, 622 Americans lost their lives in tire-related incidents. Essentially, no it is not safe to drive on dry rotted tires

you already know the answer... not safe to use... why want to risk it?

bought 2020 already 4 years, how many (i'm not using "much" means just a few) ringgit you still want to save, moreover every year tyres price keep increasing... just change it for the peace of mind.

still looks ok... not that bad for a 6 yrs old tyre...

if you seldom drive and drive very short distances... or have it in the sun all the time... these can accelerate dry rot and cracking problems

The two most mis-understood or mis-intrepreted hence (imo) mis-application or mis-judgement tyre phenomena and terminology are:
1) Dry rot and,
2) Over-inflation.

There is lots and lots of fear mongering related to these 2 phenomena ....

If your tyre not dry rot, then it is not a real Michelin.

Yes, and also rubber peel off.

All my Michelin XM, Primacy and PS have suffer from this issue.

I compared a 8yo geolander AT and toyo open AT, no dry rot there.

Yet they sell it at premium price

Ya i tot it was some freq cornering fast drive but only happens to Ps n last was kumho,mostly peeled off shoulder side by chuncks

I feel worry to much

you guys have it easy
