Curious on Overdue Pirelli Scorpion Verde Post Mortem

[inkuisitive]

Did a December replacement of a pair of Pirelli Scorpion Verde AS that I have used since 2020 for just shy of 50,000 kms. They were manufactured in 2019.

Tyre techs here said they could go for a few thousand more kms, but parking in the sun, 2000+ kms of gravel desert driving and other off-road use, and thousands of kilometres of rough tarmac surfaces meant they were suffering from dry rot with some surface cracks and tread block chipping.

Of course they were unsafe to use as they would skid if you braked when it drizzled and road surface was wet grit.

Had some uneven wear either from poor alignment or suspension wear, as some of the wear markers were reached but others still had some depth to go.

Replaced them when I saw cracks under the tread blocks under load.

Comparatively, had Kumho Crugen HP71 that I put 500 kms after the Pirellis but had to remove 6 months before and 6,500 kms before cause despite a lot of tread, they had gotten so brittle they got a clean hole puncture on the shoulder.

Question is whether I could take the word of the tyre techs on keeping the Pirellis

for a few thousand kms with no risk of blow out. After unmounting the tyres one is so out of balance it falls over on a flat surface.

Kept the tyres more out of maxing their usage on concern of pollution.

They are probably used to cheap people.
my 2 cents those don't owe you anything and good to replace maybe even earlier for me.

What is the actual tread depth? Have you done a good measurement of them say 90 degrees across all 4 treads so 16 measurements? That will give a good visual math map. That's only part of the puzzle as the other is actual condition of the tires. One can overrule the other but both are good to have.

Yes, on them being used to cheap people. A number of people who had even balder tyres than me - down to wear markers - were advising me to replace

Surprised though they can push tyres that much.

I didn't measure. Was weary when tread blocks started chipping that that maybe soft spots for punctures.

So, these tires are 7 years old and skid in a drizzle or sandy roads surface. Why would you keep them?
They are showing obvious cracking due to age and sun exposure.
If you plan on driving over 50mph, I wouldn't trust these.
Replace them.

time for those to go !

Those are a little rough, but that's because the road surface isn't being kind to the tread rubber. But the tread rubber is doing OK relative to the environment. At 7 years, it might be time to replace, depending on where you live, but the tread rubber isn't saying you should.

I now get what they were saying. I thought the tread blocks cracking underneath where they connect with the tyre was an issue.

I did drive them regularly at 120 kph but replaced them just over a month ago. Interesting they are the longest lasting tyres I have had.
