Safety test 8-year-old rubber

and about the friction heard? the greater the mass the greater the friction. As a result, the increase of inertia with increasing mass, kompensiruet increase friction.

S = V2a/2g?,
where:
S — stopping distance in metres;
Va — the speed of the vehicle at the time of the beginning of braking in km/h;
g — acceleration of gravity, equal to 9.81 m/sec2;
? — coefficient of adhesion between tyre and road.

ahahhahah, as well as the law of inertia? body higher weight, harder to stop than light! Oh the sadness...

Yes, it's in all of these factors and still have hundreds, but the masses have nothing to do with.

read carefully, and ponder what is written, namely, about the mass, the matter in suspension, in the case of ABS, it's in the tyres as the road surface, it's in the trash, it's in a sideways air flow, the temperature of the road and it is wet or dry, the thing is the reaction of the driver and so on...

so you write, it's not in mass, in suspension, brake system and so on.
The same empty car and loaded up to the stop stop in the same way, provided that the braking system can lock the wheels. Because the difference is still not masse, and other nuances.

view the tests of different brands on the same rubber. And you will be surprised how much can be a big difference. My car weighs in 1799, and let the brake at 50km per hour, and 9.9 meters on smooth asphalt. At a friend's 1300 kg, the braking let up on the meter more. tread width is the same bus from the same manufacturer. When I will start thinking with his head? Or abs and other assistance systems braking ( suspension for example) a marketing ploy? In reality, the mass is always there! Theory leave pedestrians

Ghostwraith

wow, I thought that plays a combination of factors :) my car is 1800kg brakes at 60 km per hour, 9.9 meter, put the same tires on another car, it will show different result

in fact, the result will be in the aisles of measurement error, if the braking system works the same way.
Have more than once discussed the fact that the formula for braking distance no mass, and if you discard some of the nuances that the braking distance with the same speed that the loaded truck that Lada or BMW will be about the same if rubber biolee at least comparable quality. Where it was a video test trucks loaded and not loaded against the minivan, so no difference is not revealed.

rubber for several years, dries, it loses its properties, becomes oak-what is there to argue

winter Yes, summer lasts much longer.

and even I do not understand rubber started razletaetsya after doreski or not, and how it is formulated is not clear, on the dry they were federales on dorisanne or still intact?

The pictures of the old rubber is dorasan for rain. Sorry no pics without cuts, but the rip shreds dry as well.

no matter where and how, every thing has an expiration date.the maximum for the rubber is 5 years under ideal storage

5 years is the shelf life after which it needs another 5 years to skate. don't confuse one with the other.

Vovanof

it all depends on where it was stored) I have a new Michelin pilot sports which skated almost to zero, and still drive on the tire is 01год b-a.d-cd.net/2722d06s-480.jpg
took 2 years ago))) f-a.d-cd.net/d85fda8s-960.jpg
only small cracks on the tyre sides
with Germany brought
I suspect that is not in the sun lay
Lobo Michelin is Michelin, not this ...))))

Michelin certainly gives the longest period of storage and use of tires from all manufacturers, plus a purely wear and tear, often Michelin wears out slower than similar tires from other manufacturers. I agree Michelin is Michelin, if you want the community not for tests but for real driving, then Michelin is fully justifies its price tag.

komisaroff

by ROS. standards 5 years, the Germans, too, but the same Michelin gives a guarantee of 10 years... with the note that this is not the expiration date is the time by which tires can be sold as new!
in General, a lot depends on the quality of tires and storage conditions...
well, the main factor of marketing) to dissolve the buyer — bread marketers

no on the website of Michelin, writes about the exploitation of 10 years, with the annual thorough inspections. Shelf life(before the tires can be sold as new) usually 4-5 years.

Had doubts before reading this article, as I have a brand new tire MICHELIN PILOT PRIMATE 235/45 R 17 put on the new drive (BMW) -bought 7 years ago a set( 5 wheels) and the wheel still lay (inflated) and was thinking to buy this same new tire on avito found one the same (but do not know what year it is) but the price for MICHELIN is very normal(4 thousand rubles. new), and thought purchase and will be on before the perfect couple but when now went to the pantry and looked at the YEAR of manufacture of your wheels - upset — 2001 wheel ...now I'm afraid to put it.And look at and touch the rubber, IDEALLY, and stored as needed (warm and no dampness was inflated on disk). What a pity — now apparently it(the wheel) will remain as a spare ...

When it was Bridgestone studded winter. Also not a single spike is not left and no cracks in 5 years. It was rubber! Kama and one black. I think so, the violation of technological process.

Went to the winter ice bridge kuser 5000, резине10 years, no cracks and spikes in place 80%, Sanchez is everything. I had rubber in 2001, the same summer, skated and sold with the car together... and it not peel off like not chasing

Yes, now, when I bought, then watched the release date and have seen different information regarding the age of the rubber. Yes, 5 years is the limit and does not depend on the height of the tread.

That's what happened with my 8летней rubber
www.drive2.ru/l/10150849/

Recently bought winter tires a well-known company (starts with the number 700), and so, well, I went to look at the warehouse. Almost bought wheels with a tag 12\08.

I do not believe the tests, manufacturers usually test one the tires are doing, and to users of other. After the scandal with the Nokian don't trust the manufacturers.

New tires with a single tread pattern. While testing with the other.

I have read and still do not get it... Yes it is rubber allows you to ride on public roads, but this polislik, which is designed primarily for the dry track. On the water they never rode any other polyclic exactly the same float, and riding on the ground on these tires I do not understand...

suddenly street crackery covet pseudo slick 10 years, because of its price, so they warn)))

A dust cloth wipe on the tracks. In here to dust)

Exactly. On my fat tires still had tread, but parapanda... the Horror!

It's not years and the greed of the rubber manufacturer and poor quality control. Kama, Amtel and other g-but never make it to the tread wear even with relatively normal Belarusian roads.

and here pololike for a passenger car?

Truck tires designed for it have a special designation tipo something( regrowable in English )a special depth indicators

Tarento2

I cut the rubber and see what is there already shredded rubber without cord correctly before so she razvalilas fufel drove the Chicks golodran passenger vapche do not cut

why cut the rubber?)

You can see the hairs on all planes of new rubber. The description indicated that dorezal region ( it is common practice to 888. A lot of people do)

waiting for the next brilliant thrash test type, test for safety centennial car there

I can't say anything Advan, but in my case, the rubber fell as much as '96.New well, storage.Danlop SP Sport... Skated 10,000 km in different modes, on the negative camber and stretched ( rubber is a house on a disk)... normal Flight...no hint of the fact that it goes beyond its characteristics!

koct88

th you breed people? tires of different new and torn! even the protector of the other...
and to drive civilian 8 years no limit! my winter was ФФ1 хака4. proezdil 7 years, and then bad to balance... so if it does not drive around 160-200, you will ride and the niche it will not... bullshit

Support, and about that sport rubber is softer, what the hell, it's like a rock compared to the drain, the descendants that the thick sidewall that would in turn did not develop.

gazz-gazz

1,6

Sport rubber stiffer sidewall tolsche there that would be cornering you on the cart on the track did not rassoulis, and at least the tires are the same found, and then the new one, the old another...

And the garage, with extremes from -30 to +30?

Sorry, didn't read everything, but keeping the rubber on a warm warehouse not much better than the sun...

And kordiant would have brought the stroller.

The main reason is not different heating of the layers, and in that 5 years after vulcanization starts to decomposes sulfur. Sulfur is the main binder in the tire.

The first season you ride in a civilian car on TOYO 999 . When they took the sellers were looking at changing like an idiot.

Now other riders will speak. what tires are old and the properties of its lost)))
comparing civilian ride riding on the track)

Well, I only have seven years to eight her protector will be less than 1.7 mm. — time to change!

On this tread in wet conditions? Freaked out though! ))))

In our region, almost half in that age.

Age does not paint any tyre
I have the factory four-year Kumho one cord broke and this is when the mileage total
40 thousand km and high tread, the car was going and jumped

Surprise! Surprise! Desert's desert! Pseudolite bad brakes in the rain and zamylivaetsya in clay! The life of a rubber — 4 years! To the whole wheel jerked it is necessary to blow at least 40 ATM (stomach burst). Article about the fact that we vegetali a barrel of gasoline.

Saw her on Craigslist!) 20 p for the set gave))

China soft grip and stinks when overloaded) But its worth the money!))

in China in the summer and ride is fine
don't say something against just consider what will happen !
riding aggressive

rubber as with any polymer, the price decides everything
not casual in Japan one-year-old banned
the tendency is to just change more often
if the manufacturer wants to he will make and durable rubber

Yuzal 20-year-old Pirelli rubber, skated on it for 6 years (all year round), no questions asked.
It is not the age, but in a specific pattern.

I 6летняя rubber seals summer too, were chunks of rubber to drop.

With nano coating from all natural factors ))

Go by what you have) for civilian use there is no difference I believe. And you're tripping in the city without a brain, and can be on the newest and best tires with the most modern electronics!

the article is interesting.
if rubber for 10 years of operation has not become harder, what does that mean?

first, what year trader began to indicate, and secondly, it's pure marketing, nothing to do with durability having

SidorKovpak

Oh, you guys in a certain part of world you live in, carbon black, silica. Ears whether you go, whether you deliberately. Here I am in 2013 I bought a b\y exogamy a Velcro ® 2003 release, the remainder is 80%. Winter 13,14,15, drove on it for about 45000 km and is sold with the machine as 50% of the balance, still safely on 2 of the season. Next. Zero dragged b\y tires and sold here in Siberia, so summer! on average, othazhivali 4-5 seasons. And now we take a new in stores with the "lesser content of say and lots of zilantov" and enough for 2 summer season, winter to 3.

you compare hot salt. about durability, see trader)

The article about sport tires. Maybe new rubber and erased, but it holds.

Bookmark and repost. Will anyone who is trying to tailor the show. Krolowa leads to popadalovo (C)

Tiny Melons))we welcome you)))

Chet resu no desire to spoil.let's better you do it and the video will record and post on YouTube and we'll see.

take an awl and poke at the slick and civilian tires — the difference will immediately see ;)))

did not notice this particularly.well, if only when corduroy climbs.

meant "soft working surface" bočiny Yes.hard.that was not dropped...and Jesse civil — only winter and primer...

perhaps you are confusing something softer sports tires civilians? well, if only the cargo to compare.I have seen your oak wheels, the sides of hard not to broke and kept turning the tires to regular wheels no. Maybe of course you wanted to write about the composition of the rubber, Yes that's it's softer. I'm here about this time... the main thing that sellers are not told that all Sportivnye as tough because the sport tires, softer civil...

very interesting

well.

Thank you. I've looked at. Silica — precipitated silica, a "white soot". Aka Aerosil, he neosil. Absolutely inert white fine powder white. Is used as a filler in a rubber compound anti-caking for the food products and premixes (additives for feed), and so on.
About the interaction at the molecular level is overkill IMHO.
We work with aèrosilom and neoceram. This is trade names, and silica . Prepare a premix, as well as components for the glass industry, where the flowability of the materials is important for accurate dosage of components.

OK Google

silica is a material which in its composition resembles ordinary sand, however, it is located in a different physical condition. At the molecular level, this component interacts with other molecules and makes the protector more rough, which improves grip.

Silica acts as a kind of antifreeze, it makes the tire more resistant to strong frosts and temperatures are warm. It is also worth noting that silica affects the elasticity and softness of the tire, it is not only a filler but also an active component that strengthens the density of the tyre.

What is the "silica"?

With dust glass Micheline energy supposedly resistance easier

Cracked? Well, well.

Yes Tanya well soooory

OK!

I'm in the best ponimaniye!,

Cracked? Well, well.

you have kids?

MS. SHEA, not ZHY SHY ayayay (

Physics, grade 7. When heating a substance, in our case, the air, expanding.

>> pumped up wheels to 2.0 ATM. and rolled under the load, until the pressure rose to 2.7 ATM.;

Uh. This is what happens when you drive the tire pressure itself is increased by as much as 35%? This is because of what? The tire well is sealed, excess air nowhere to take.

I have right now is to temporarily bridge 2003 if not litate, and crawl the rules . ) but worth a pile begins to stratify .

Share

Test thing necessary and useful . Critical point pressure in the tires if neoshibayus 2.7 bar ? Photo is not the correct wear penny Joy says pumped . And so well done that protesting, there are those who do not understand they are rubber 2001, go, and say all the rules ) grip the fire .

Test good when it is adequate . To ride on the track for an eight-year tires just nonsense, of course the rubber dries out and the lap times increased . This just makes no sense to train if only for this
On the road to osathanon your Messershmidt managed last season to ride on 15-the summer tires, Yes, morally dumb at this ride, but I did not see anything bad

no matter where and how, every thing has an expiration date.the maximum for the rubber is 5 years under ideal storage

whence infa ?

jurik-71

No, just ride this one, and drive here is another. Summer tires I have long held.

That's exactly what you can drive on 8 year old slicks nonsense, for track only the best, from the rubber too much

WINDisel

new with worse than an old used — I thought everyone knows about it...and without sports

I do not understand anything)

Autobaks

Hard you will cope with the machine even if you are in elementary (rubber), not fucking understand

I washed in no doubt who wrote that 5 years storage + 5 years of operation . Who writes 3 years of storage . Think important in the first place Its not who as it should be with compliance of all temperature properties does not store it is much more important than anything else .

FJ-TRD

A friend Michelin 2000 X5 of the same year, the rides and not steamed
And for the pattern and replacement +++ plyusanul

I now is temporarily 2003 . Do not risk today the experience set as a slow, not very ) but slows down . 5-6 meters more fresh rubber is non-Abs . Warming begins to colitisa . But you can ride Michelin, Pirelli say 5 years storage + 5 years of operation, with the observance of the storage conditions .

Understand, right now, I go to spin them in the service look no of turns they though. And why do I think that to balance these balloons is not just, I think to precott and then balance.

No. Just so nothing blows up. If not pumped and no hernias

In the rain it's clear, I'm more worried about, I'm not a racer of course as many, but with the speed of 200-200-with a small on the highway in the summer love to ride. Yesterday I read in the Internet all ohineyu, now constantly thinking if it's true that they explode

Go for a drive. Just be careful in the rain steer.

Damn, took today the new Yokohama ' 08, read the article now worried what to do?

I have a rubber butt before 2007, 2009, tried in Federal 250-260 is fine, just the spring and no rain . When it rains not more than 130

After Yokohama ride kordiant, the second definitely will be better. The price is still normal and not noisy like a tractor, I am very happy that I changed tires

also praised cordiant until he went pieces of the tread as this ESA from the post. very nasty rubber would be, but 15 thousand this is not it.

This is exactly our rubber and the holes will go through the puddles on the pavement. Himself ride Kordiant Road Runner, super rubber. Not many people know her, but who tried not want another set, I the second set I bought this year.

Excellent article. He took the bus in 2010, still like new ride, in the rain and without rain. There seems to be bought: nokian-spb.ru/shinomontazh/ (if anyone should)
