What is white dot on a tire mean?

The White Dot (Dynamic Balancing Dot)

Regardless of the type of wheel, if there is no red dot, mount the tire with the white dot next to the valve stem. The white dot indicates the overall light dynamic balance point of the tire. In other words, it's as though the white dot represents a bit lighter in the area of tire.

What does the painted dot on a tire mean?

The red dot indicates the tire's high point. Most of the time, a wheel will also have a dot—either a drilled dot or a sticker to indicate its low point. If you have these marks, you should align the red dot with the mark on the wheel. By doing this, you minimize the vibration caused by the high point of the tire.

What are the red and white dots on new tires?

On the sidewall of most new tyres are red and yellow painted dots. If these marks are aligned with particular points on the wheel, you will reduce the amount of weight required for balancing. The less lead weight used, the lower the cost of wheel balancing and the higher the profit on the job.

Does dot matter on tires?

1. In terms of the DOT Date Code, some might assume that the number states when the tire was approved. On the contrary, the DOT symbol by itself simply indicates that the tire is approved by the Department of Transportation to be legally used on the road.

Why do my new tires have a yellow dot on them?

The yellow dots can help minimize the amount of weight needed to balance a tire and wheel assembly by mounting the tire so that its lightest point is already matched up with the wheel's heaviest point. The yellow dot indicates where the manufacturer has identified the lightest spot on the tire.

WHAT RED AND YELLOW DOT MEANS ON TIRES WHERE TO PUT RED DOT ON WHEEL

What does a blue dot mean on a tire?

The blue dot represents the high runout location on the wheel, while a red dot on the tire represents the coordination runout position on the tire.

What does green dot on tire mean?

Awl vents are of a defined diameter and are made to a defined depth at defined points around the tire. An amount of green ink is deposited by the tool on the sidewall as the hole is made. This green spot indicates the location of vents around the tire and shows the venting process was completed.

How do you read a DOT?

Remember that the last four digits of the code are the date the tire was manufactured. You can check the first two digits of the DOT code to know the week of the manufacturing. The last two digits will reveal the manufacturing year. For instance, when it was written in 0203, the manufacturing year was 2003.

How do I know when my tires expire?

The last four numbers represent the manufacturer's date. The first two numbers indicate the week, while the last two indicate the year. (For example, a tire with the number 2910 was manufactured in the 29th week of 2010.)

Are 4 year old tires still good?

We recommend replacing tires aged 6-10 years, no matter how much tread remains. When it comes to replacing tires, things can be a little unpredictable. Mileage, condition and routine maintenance all contribute to the tire's safety and usability. You should replace them if you think they may have compromised integrity.

Where does the yellow dot go when mounting a tire?

When performing weight match-mounting, the yellow mark on the tire, indicating the point of lightest weight, should be aligned with the valve stem on the wheel assembly, which represents the heaviest weight point of the wheel assembly.

Where does red dot on tire go?

First, if the tire has a red dot, the yellow dot is ignored! The red dot is then lined up with either the “low point dimple” (on steel wheels) or next to the valve stem on alloy wheels. Regardless of the type of wheel, if there is no red dot, the yellow dot is positioned next to the valve stem.

What does the red dot and yellow dot mean on a tire?

If it is lined up with the yellow dot, the valve stem is located at the heaviest part of the tire. If it is lined up with the red dot, then it is located at the lightest part of the tire. These dots guide the technician to make sure that the tire is properly balanced during installation.

How many years do tires last on average?

On average, people drive between 12,000 to 15,000 miles a year, which means the average good quality all-season tire will last somewhere between three and five years, depending on maintenance, driving style and conditions, etc.

How often should tires be replaced?

The NHTSA recommends that tires be replaced every six years regardless of the number of miles driven. Proper inflation is the Holy Grail of tire maintenance. Too much or too little air in your tires is guaranteed to cause you trouble and uneven or excessive wear over time.

How old should new tires be?

though it could have new tread, it is still an old tire. Tire Rack's recommendation that a tire should be replaced ten years from the date of manufacture or six years from the date it is placed into service applies to spare tires, as well, so if your vehicle is six years old or older, it's probably…

What does DOT stand for?

DOT is an acronym for damage over time, and it's used in computer gaming to refer to acts that slowly cause damage to a character, such as poisoning or a spell.

Is the DOT number on both sides of the tire?

The DOT number is stamped on both sides of the tire sidewall and can be found by looking for the DOT designation on the sidewall. The other sidewall of the tire will have the initials DOT and the manufacturer's plant code.

What is a DOT code?

This code is an alphanumeric code that can be seen on the sidewall of every tire. The DOT requires tire manufacturers to stamp the code on each and every tire. The reason for the DOT code is, first and foremost, vehicle safety. For example, the code helps with safety by making it possible to track sales.

Can you put air in a tire filled with nitrogen?

It is FALSE that air cannot be used to top off a tire filled with nitrogen. It is simply not true that air and nitrogen cannot coexist inside a tire. There is no harm in topping off a nitrogen-filled tire with regular air.

Can you put regular air in a nitrogen filled tire?

If you have nitrogen filled tires and need to refill them but there is none available, it's perfectly safe to fill them with regular compressed air. However, you will later have to purge the tire and refill with nitrogen to continue maintaining the benefits nitrogen tires deliver.

Is it worth it to put nitrogen in my tires?

Since nitrogen molecules are bigger than normal air molecules, it is harder for them to leak out. This means a tire filled with nitrogen will maintain air pressure longer. Therefore, they say, you'll roll on tires that are always properly inflated, resulting in better fuel economy and longer tire life.

What does a red dot on a TYRE mean?

The red coloured dot marks out the highest point in the tyre, or the “radial force variation first harmonic maximum” – where the centrifugal forces are at maximum on a rotating tyre. In most cases, your wheels will also have a dot – either drilled or marked out by sticker – to signify its lowest point.

What are the colored lines on new tires?

Since thousands of these flat tread slabs are processed in a tire manufacturing facility every day, the manufacturers often print stripes (often featuring multiple stripes or various colors around the tire's circumference) and/or alphanumeric codes to identify the exact type and size tire for which the tread slab is ...
