Oznake na gumama

[xxx]

Vidim na nekim gumama da na bočnici imaju otisnute neke točke, najviše u
zelenoj boji.
Jel to ima kakvu svrhu ili ?

Are you seeing dots? Those color-coded sidewall markings serve a purpose
Share | Print Comment

By Peggy J. FisherC

ROCHESTER HILLS, Mich. (Aug. 13, 2007) - Dots, dots everywhere. There are
lots of dots in our lives, whether or not we recognize them.

There are techie dots called pixels that make up the images on our computer
monitors and television screens. There are those voluptuous dots on that
little "itsy, bitsy, teeny, weenie, yellow polka dot bikini" that you stared
at near the pool or on the beach last weekend.

And there are those paint dots that you see almost every work day on the
lower sidewall of new tires. While you may understand the importance of the
pixels on your screen and the effect that polka dots on that bikini can have
on you, do you know what those dots on new tires mean and how they can
impact you?

If you guessed that these paint dots are supposed to be used when mounting
tires, you would be right. But these dots can be very confusing since some
manufacturers use them while others don't, and some dots are different
colors than others. The question you have probably is, "What do they mean on
the tire I am mounting?!" And that is an excellent question.

A question of balance

If you are staring at paint dots on truck tires, you should know that they
were installed to assist you in correcting tire balance and radial runout
conditions.

Manufacturers of commercial truck radial tires may apply a variety of
colored dots on the lower sidewall for customer or factory purposes. Not all
tires have markings and even the paint dots on those tires that do are
temporary and can be scuffed off during normal shipping, handling and use.
That's why you don't usually see them on used tires.

The dots on new tires that have them are not critical but are intended to
guide technicians when positioning the tire on the rim during the mounting
process.

Since it is very hard to make a tire that is perfectly balanced, some tire
manufacturers apply yellow dots that indicate the tire's light balance point
and serve to help you balance the assembly while mounting the tire. The
yellow dots should be aligned with the valve stem on both steel and aluminum
wheels since this is the wheel's heavy balance point. This will help
minimize the amount of weight needed to balance a tire and wheel assembly.
So usually, whenever you see a yellow dot, match it up with the valve stem.

This is always true except in cases where a red dot also appears in the
lower sidewall. The red dot indicates the high point for both radial runout
and radial force variation. As I'm sure you know, not only is it hard for
tire manufacturers to make a perfectly balanced tire, it also is very
difficult to make a perfectly round tire.

Tires tend to have high spots and low spots. The difference between the high
and the low is called radial runout. Radial runout changes the radius of the
rotating assembly, causing it to raise and lower the vehicle as it rolls
along. That gives the perception that the tire is "hopping" or "bouncing"
down the road and ends up delivering a rough ride to the driver and
irregular wear to the tread.

Radial force variation is similar to radial runout and is a result of a
heavy or thicker area being manufactured into the tire due to variations in
component thickness, placement and overlapping. Radial force variation
applies more force against the road at the tire's thicker spot as the tire
runs, which causes one sidewall to flex differently than the other. The
result is tire/wheel assembly vibration and irregular tread wear.

To avoid or minimize these problems, whenever you see a red spot, match this
up with the valve stem-unless you happen to have a steel wheel that has a
dimple on the exterior side of the rim area. The dimple indicates the wheels'
low spot and is spec'ed by some original equipment manufacturers so that
they can match mount tires and wheels installed on new trucks at the
factory.

If you see both a red as well as a yellow dot on the tire, the red dot takes
priority. An easy way to remember this is the phrase "Red Rules." Ignore the
yellow dot and match the red dot to the wheel low point dimple as some
vehicle manufacturers do or, if no dimple is marked on the wheel, align the
red dot with the valve stem.

Other colors/no colors

When you are installing dual tire assemblies on a vehicle, always "clock"
the two wheels so that their valve stems are 180 degrees apart. This is done
for two reasons.

The biggest one is so you can access the valve stems and take and adjust
inflation pressures while the tires are on the vehicle. However, a secondary
reason is that it also puts the balance points opposite each other and
counteracts any of the remaining imbalance, radial runout or radial force
variation.

If you see any blue, green, purple, white, pink or orange dots, just ignore
them. They are "mystery" dots and are there for factory purposes. Once the
tire leaves the manufacturing plant, dots of those colors have no use.

Some manufacturers do not put any dots on their tires.

A tire with no dots does not indicate a lack of tire uniformity or factory
inspection. It simply means that those tire companies didn't want to put any
dots on their tires. So you are on your own. If you find imbalance to be a
problem after mounting the tire, rotate the tire 180 degrees on the rim and
then recheck the balance.

Since all the tire companies seem to have their own policies regarding
mounting dots and there was no one source to find this information, the
Technology and Maintenance Council (TMC) asked each company to advise it of
its mounting markings and what they are to be used for. It then produced
RP243 Tire and Wheel Match Mounting Markings.

This recommended practice guide provides the accompanying table (above),
which outlines the tire balance and runout markings for medium commercial
radial truck tires.

All dots not listed in the table are for factory use only.

Once a tire is mounted, both sides of the tire should be checked for
concentric bead seating. Non-concentrically seated beads often result in
irregular tread wear and ride disturbances just as imbalance, radial runout
and radial force variation do, so don't go to all the trouble of matching
the correct dot to the valve stem and then screw up by not using enough
lubricant and improperly seating the tire on the rim.

It's these little details that can't be overlooked but ensure optimized tire
performance.

Bitne pri montaži gume na felgu. Koliko vidim, tekst je pisan kao da se
te točke nalaze na gumama za kamione, pa nisam siguran da li se isto
odnosi i na gume za osobna vozila.

Savršeno balansiranu gumu je teško proizvesti, pa se žutom točkom
označava laganiji dio gume.

Žutu točku bi trebalo poravnati sa pozicijom ventila na felgi (ventil je
"teži" dio felge), pa je kasnije potrebno manje utega za balansiranje.

To sa žutom točkom je točno dok se ne pojavljuje crvena točka. Naime,
nije baš lahko proizvesti savršeno okruglu gumu, pa crvena točka
označava "high point" (valjda malo izbočeniji dio).

Ovo gore je objašnjenje high i low pointova.

Crvena točka se poravnava sa ventilom, osim ako imaš čeličnu felgu sa
označenim low spotom na vanjskoj strani felge gdje dosjeda guma.

Ako su ižuta i crvena točka na gumi, crvena ima prioritet. Ako felga
nema oznaku, crvena se poravnava sa ventilom.

Plave, zelene, ljubičaste, bijele roze i ostale točke nemaju nikakvo
značenje, odnosno tu su za potrebe tvornice.

Jednom sam čitao da se radi o oznakama bez ikakvog značenja za krajnjeg
korisnika ili vulkanizera. Navodno su to oznake bitne za lakše snalaženje u
tvornici u procesima nakon silaska gume s trake.
