Tire life

[C moa]

I received this document this morning, i went to see quickly on google but i found nothing convincing.

Thank you to the specialists for enlightening us.

By the way, since the auto industry has been around "just in time" and "just in time" for a number of years now, I have a hard time understanding how tires could sit in sheds for long. several years without being sold ...

Indeed, the tires age and become brittle.
I have a set of tires from my ex-BX that I wanted to give to my mother-in-law (405 station wagon SR) because they are the same wheels.
The tires had driven 10000 km (usually between 45000 and 60000 km with my tires) but had been stored for 5 years.
I brought them to a friend who rides tires. He looked at them and showed me all the age defects that appear, cracks and anything that can cause an accident. In short, even when we are mounted on a car (therefore no weight distortion) a tire ages and can prove to be dangerous.
Better to have 'classic' tires with high flow, than rims with rare tires which may have been stored for years ...

Hello,
One day, I received an old ladybug, with nice tires, but old.
Result, I hit a double head to tail at 60km / h in a simple turn with light rain.
(ok, it was a ladybug )
On the strength of this experience, I was wary of tires, and since I don't drive much in general, I noticed that already after a year, the tires lose a lot of their grip. Even if they are not worn.
(roundabouts are a good test)

To make them last and improve safety, the longevity of your car and its lower consumption, a check of the annual parallelism as a balancing of all the tires every year is not useless.
By doing it every year we see that the tires are unbalanced because the wear is not uniform (all it takes is a quick kick).

Otherwise this also raises the question of the spare tire which is by definition a wheel as old as our cars. Even re-inflated at regular intervals, it remains an old tire, sometimes deformed by the fixing system under the boot. So when you put your spare tire, you still have to drive more calmly in case ...

I heard in the 70s that bikers aged their tires for about a year to increase the mileage. Is it still true today? Are there bikers in the visiting room?

As a biker, I would say that the roundabouts (the exact term is roundabout) are not at all a grip test ...
Very often they are smeared with diesel, oil, sand ...
The most dangerous are those located near gas stations.


It seems to me that recent gum mixtures are aging much faster than 15 or 20 years ago.


Is it a perverse and undesirable effect of the development of rubber or a marketing component managed by tire manufacturers to make us consume more ...


We are talking about a consumption period of 6 years. It becomes quite short for all those who do not manage to wear their tires in this period of time ...

After trying French escaped tires under Michelin license which take care very quickly, I also used second-hand tires ... This very "ecological" sector risks suffering if a DLC is decreed for the tires ...

From what I see, marketing is mostly about comfort. The peneus tend to harden as they age and become less comfortable (not to say tape c ..).

But are they really more durable? That is the question.

[I Citro]

For comfort ... my tires on electric cars are inflated to 3.2bar which has a very positive effect on the range.

The best way to maintain comfort is to ride cool.

Very good response from Citro.
Especially since my "roundabouts" are located not far from an "oil tanker" point and yes, the tanks of the trucks often overflow in this case ...
I am also a "biker" ... and am able in this sense to detect if a road is "oily" or not.
And so, with a little experience, you realize that tires that are a little old hang less over the years.
Oh yes, I forgot to say that I love to slide lightly in the "roundabouts" because not very dangerous. (With a little experience)
Another way to check the efficiency of your tires is to turn around with the handbrake.
When I have good tires, I can't do it, even on wet cobblestones
We can be cool and do hard tests too.
