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.

What does red dot on new tires mean?

The red dot indicates the tyre'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 and ignore the yellow dot.

Where does 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 are the red dots and yellow dots on tires for?

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.

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

What does orange dot on tire 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 does the green dot on a 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.

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.

Why do my new tires have colored dots?

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 is the yellow dot on new tires for?

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.

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.

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 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.

Can I mix regular air with nitrogen in my tires?

Actually you can mix regular air and nitrogen, but with risks. Some facts. Nitrogen has a larger number of molecules than air, so it can maintain tire temperature at bay. For the same reason, the elasticity of the tire also is also better.

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.

How much does it cost to fill your tires with nitrogen?

If you purchase a new vehicle and want nitrogen-filled tires, you can expect to pay anywhere from $70 to $175. If you would like to fill existing tires with nitrogen, the initial fill-up will cost about $30 per tire. That's because the existing tires need to be purged of their oxygen with multiple nitrogen refills.

What are the disadvantages of nitrogen filled tires?

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.

How often do you fill nitrogen tires?

Usually, a tyre loses approximately 1.5 psi of pressure every month on normal air which can be expected across 2-3 months on a nitrogen filled tyre. So, ideally, you should refill your tyres every 2 -3 months if they're nitrogen inflated.

Do tires have dates on them?

Every tire has a birth date—the day it was manufactured—and an expiration date that is six years from that manufacture date. Most automobile manufacturers warn drivers to replace vehicle tires after six years. To wait any longer than that is a gamble with tire integrity and is risky for drivers.

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.

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.

Is it OK to buy 2 year old tires?

Old “New” Rubber

The tread is good, and the manufacture stickers may still be on it. When tires reach a certain age the rubber begins to dry out and crack. That can make it unsafe for road use because it may run the risk of blowing out, falling apart, or lose traction during bad road conditions.
