Does red dot go to valve stem?
If both red and yellow dots are visible on your tyre and you don't have any dots or marks on your wheel, red takes precedence over yellow and you should align the red dot with the valve stem.
The red dots identify where the tire is flattest — the lowest point on a tire. The red dot should be directly across from the highest point of the wheel, which is usually indicated by a colored dot or a notch on the wheel. If a tire has a yellow and red dot, the red dot takes precedence when balancing the tire.
Red dots indicate the highest point of tyre.
Nowadays it isn't necessary to align the dot with the valve stem, as wheel and tire manufacturing has improved enough to ensure good balance however the tire is mounted with relatively few wheel weights needed. They were used at one time to assist the installer with locating the heavy and light areas of the tire.
In fact, these colored dots serve a specific purpose in helping the tire technician correctly balance the tire. Creating a tire that is perfectly balanced and perfectly round is nearly impossible. Manufacturers make sure to label these inconsistencies with dots, so they can be corrected during the mounting process.
The Weight Method
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.
Conclusion. For many, green dots are a huge improvement over red dots because of eye physiology. Faster target acquisition, better contrast, sharper reticle…the list goes on.
The idea is simple you utilize plates of glass and a light. A red dot has a spherical mirror that reflects the light emitted from an LED of its axis focus. That spherical reflector has a special coating that only reflects red light. This prevents other light from disrupting your reticle.
A little rubber becomes chemically incorporated into asphalt roads, because asphalt and rubber both are made of petroleum oils. But the vast majority wears off as small particles that are rinsed off the road by rain, or blown off by wind, ending up in the soil, on plants, and in lakes, rivers and streams.
That's up to you. So, the red dot icon on Apple Watch means you have a new notification that is not yet read, and you can check it or dismiss the red dot by swiping down from the top of the Apple Watch screen.
What are the red and white dots on tires?
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.
DOT Number or Tire Identification Number
This 12-digit identifier shows what factory the manufacturer built the tire, and the week and year it built the tire in. This date code will be the last four digits in the code.

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 ...
The DOT serial number located on the inside sidewall near the rim. The letters “DOT” are followed by eight to thirteen letters and/or numbers that identify where the tire was manufactured, tire size and the manufacturer's code, along with the week and year the tire was manufactured.
It tells you who manufactured the tire, where it was made, and other tracking information. Plus, it indicates that the tire has passed the Department of Transportation's testing and NHTSA manufacturer requirements. The raised numbers of the DOT Code are placed together and often enclosed in a raised oval.
Red dots increase target acquisition, shot timing, and accuracy. That's why I have one co-witnessed on my best AR-15 scope. In fact, shooters who use red dots on their rifles love them so much that they're putting them on their defensive handguns.
Vegetarian food is identified by a green symbol while non-vegetarian food with a red dot.
A red dot is a single moment in time where someone's choices, actions, words, or behaviors contribute to or tolerate violence in any way.
Regular gallery visitors will know that a red dot next to an artwork means the work is sold. This is an American gallery tradition, which has now become common practice around the world.
If you have directional tires on your vehicle, they are simply marked by an arrow, and most of the time the word rotation, or direction of rotation, etc. Asymmetrical tires have an inside and outside to their tread. Tire manufactures will often do this to optimize the traction and wear capabilities of the tire.
What happens to all the tire dust?
Some of the tyre dust gets mashed into the road. Most of it gets blown off away from the road by the air turbulence of the vehicles. And rain easily washes the rubber dust off the road into the nearest waterways where it ends up as sediment on the bottom of creeks, ponds and wetlands.
The primary function of belt plies is to provide strength and stability to the tire tread. They play a role in improving tire mileage, impact resistance, and traction. Steel is the most common cord material used in belt plies.
Why do I have a orange dot in the corner of my phone phone when I'm on phone calls ? An orange indicator means the microphone is being used by an app on your iPhone.
These dots are called indicator lights, and they alert users to when an app uses their camera or microphone.

There are three major types: tire prints, skid marks, and scuff marks.
The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire's width. The bigger the aspect ratio, the bigger the tire's sidewall will be.
They are called 'vent spews', a weird name for something extremely common. Other names include sprue nubs, tyre nibs, gate marks or nippers. The hairs actually play a vital role in the tyre manufacturing process.
January 10, 2016. Green caps on tire valve stems usually mean the tires are filled with nitrogen instead of ordinary air.
According to Tire Review, new tires should always go in the back. Rear tires provide the vehicle stability, and if they have little tread, then stability is lost.
How long does it take to get flat spots out of tires?
The amount of driving distance and time will vary, but achieving normal highway speeds for over 20 minutes will relax most flat spotting.
The heated polymer compound in tyres causes the black streaks they leave on the driveway. Marks are more likely to be left by hot tyres. Many of the chemicals used in tyre compounds are water-resistant, so the marks will not fade in the rain, meaning they will be visible for months.
First, here's what the rule under the red flag race is: All drivers are free to change their tires depending upon what strategy they'd quite like to work or function with. This, in turn, is decided based upon the nature of the track and what conditions one is eventually battling.
Valve stem damage – New tires typically come with new valve stems, because the old ones tend to wear out. If you have older valve stems, they may go bad over time, due to use, dislocation, and exposure to chemicals on the road, such as road salt. They may corrode and go bad.
Replacing your valve stem is an easy task to do, even if you aren't a mechanic. New valve stems cost about $10 dollars to repair if you do it yourself. If you bring it to the shop, it will cost about $30.
Coloured caps (either Red or Green) indicate when a tyre is inflated with Nitrogen gas rather than compressed air.
Possible causes include an incorrectly set valve clearance − or the valve seat insert or valve guide were not remachined centrically. An excessively large or small valve guide clearance can also have fatal consequences.
The QVC Quick Valve Change Tool allows the user to replace the valve stem without removing the tire from the wheel. Save yourself time, money, and the headache of replacing valve stems the hard way.
We have good news for you! You CAN continue driving! The purpose of the air valve cap is to keep dirt and debris out and to keep air inside in case the air valve ever does leak (you can find out if it is leaking by spraying some Windex on the valve and see if it bubbles).

How long does it take to replace a valve stem on a tire?
Replacing a valve stem is a very quick procedure. In most cases, we can change a valve stem on your wheel and install it on your car in 10 minutes or less.
In most cases the the fastest way to replace a valve stem is to take it to a tire shop and have them remove the tire and replace the valve stem using aid of a tire machine. However, for instances where this is not an option, a tire can be removed and the valve stem changed manually.
When to Replace Valve Stems: A good test for damage is to flex the stem. If you see damage or cracks or the rubber looks really old and dry, replace it. If you're changing your tires it's a good idea to change the valve stems, too.
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.
The main benefit of nitrogen-filled tires is that the loss of tire pressure is slower, because the gas in the tire escapes more slowly than air does. With more stable tire pressure, the thinking goes, you'll get better gas mileage and get full tire life since you're always rolling on fully inflated tires.
It would cost you anywhere between $70 to $200 when you purchase a new vehicle and want nitrogen-filled tires. You will be paying close to $30to fill tires that have compressed air in them. That's because the oxygen needs to be removed with multiple nitrogen refills. Topping off will cost you $5 to $7 per tire.
The average full car valve replacement cost is between $900-$2,000. A single valve replacement cost is about $100-$200. A valve replacement job is often expensive due to labor costs. Mechanics can spend all day on a full valve replacement, depending upon the size and type of an engine.
If the valve stem is leaking, you can easily fix it yourself with a valve stem tool. You only need a valve core tool and a package of new valve cores (both inexpensive). How to fix a tire leak is simple.
Step 1: Make sure it's your valve stem that's leaking.
Apply a mixture of water and dishwashing soap to the valve with the cap removed. If bubbles start to appear, your valve is leaking. If this is not the case, and there is a definite air leak, it will be located elsewhere on the tire.
