What do yellow and red dots on tires mean?

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 are there red and yellow dots on my new tires?

On the sidewall of most new tires are red and yellow painted dots. These are markers or guides to be aligned with particular points on the wheel.

What do yellow dots mean on a tire?

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.

What's the red dot on a tire for?

The red dot may be aligned with a 'dimple' on the exterior of the rim. This indicates a wheel's low point and should be adhered to in the mounting process. By pairing a dot with either the lightest or heaviest weight area, you will achieve the optimum balance point during installation.

Where should the red dot on a 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 RED AND YELLOW DOT MEANS ON TIRES WHERE TO PUT RED DOT ON WHEEL

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.

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 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. 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 are the green dots on tires?

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.

What does a green dot on tires mean?

Green caps on tire valve stems usually mean the tires are filled with nitrogen instead of ordinary air.

How do you read a tire dot?

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.

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.

How many years do tires expire?

It may be tentative, but tires do have an expiration date. There is a general consensus that most tires should be inspected, if not replaced, at about six years and should be absolutely be swapped out after 10 years, regardless of how much tread they have left.

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.

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 do red valve stem caps mean?

Red means too low; yellow means too high. When the cap is black, you're good to go. One catch, though: these things have to be tuned for your tire's optimal PSI before they leave the factory, which means if you want to swap them onto a different car or you buy different tires, you might need a new set.

Why do new car tires wear out so fast?

New tires or factory tires wear out quickly because car manufacturers use soft rubber for their tires. This soft rubber wears out much faster than aftermarket tires.

How old can tires be and still be sold as new?

Investigation: Aged tires being sold as new. There are no laws or regulations prohibiting the sale of tires manufactured more than six years ago, but both safety experts and many vehicle manufacturers recommend against using any tire older than six years.

How often do tires need to be replaced?

But even if there's plenty of tread left, tires should be replaced if they're too old, at least every six years. That's because over time, the rubber will dry and crack, possibly leading to a blowout or flat tire.

When should tires be rotated?

During rotation, each tire and wheel is removed from your vehicle and moved to a different position to ensure that all tires wear evenly and last longer. Tires should be rotated every six months or 6,000 to 8,000 miles.
