What do the yellow and orange dots on tires mean?

These are markers or guides to be aligned with particular points on the wheel. The alignment matters for the balancing of the wheel: If these dots on the tires are properly aligned with certain points on the wheel, minimal weights will be used for balancing.

What do colored dots on tires mean?

The spots on the sidewall of your tires were specifically placed by the manufacturer to guide the tire installation process. In fact, these colored dots serve a specific purpose in helping the tire technician correctly balance the tire.

What does the yellow dot mean on tires?

Dot Marks The Spot

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.

Why do tires have yellow and red dots?

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.

Why is there a red dot on my tire?

Tire manufacturers recommend the correct positioning of the red and yellow dots with respect to certain “landmarks” on both steel and alloy wheels. These dots can be used to mount tires for optimum initial balance and minimum ride disturbance – where the dots go depends on which dots – and which wheels you have.

The first two numbers of this grouping indicate the week of the year your tire was manufactured. The final two digits indicate the year that your tire was manufactured. For example, if your final four DOT numbers are 3020, your tire was manufactured in the 30th week of 2020.

What does white dot on 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.

Is when the yellow dot is matched up with the rim's heaviest point?

The yellow dot should be matched up with the rim's heaviest point, which is called weight matching. These points occur innately as part of the manufacturing process because it is impossible to create an absolutely perfect, even, round tire.

Is it worth it to put nitrogen in my tires?

Improperly inflated tires can wear unevenly, wear out faster, and ruin your fuel economy. Simply put, pure nitrogen does a better job of maintaining the right tire pressure, thus enabling your car and its tires to work as efficiently as possible.

Can I mix nitrogen and air in my tire?

Using compressed air in tires that have previously been filled with nitrogen will not harm your tires. While mixing the two won't result in an adverse chemical reaction, it will dilute the purity of the nitrogen and lessen its effectiveness.

What is the difference between air and nitrogen in 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 is the yellow dot on a motorcycle tire?

On motorcycle tyres, and some car tyres too, there's a yellow dot on the sidewall. I know this yellow dot has something to do with balancing the tyre and wheel. The yellow dot will be either the heaviest point of the tyre, or possibly the lightest.

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.

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.

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 ...

Does Walmart fill tires with nitrogen?

Click to enlarge. As of April, ISG said in a press release, 28 of Walmart's 54 fleet service centers are using the ISG nitrogen system, with installation of the system due to be complete and the remaining centers by the end of this year. Nitrogen tire inflation can provide savings in fuel consumption and tire wear.

Why does Costco fill tires with nitrogen?

The warehouse club uses nitrogen to fill its tires instead of compressed air, which is what most other dealers use. “Nitrogen retains tire pressure better over time than compressed air, which can positively impact the life of your tires, as well as the fuel economy of your vehicle,” according to Costco's website.

Do all new tires have nubs?

There are little rubber hairs that you see on every new tire. Technically, they are called vent spews, which gives away their purpose for being on the tire. Many people think these hairs play a role in noise reduction or indicate wear but their primary purpose is air ventilation.
