Where does the red dot on a tire go?
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 color dot goes by the valve stem?
If the valve stem is located at the heaviest point on the tire, it will be lined up with a yellow dot on the sidewall. When a red dot is lined up with the valve stem you can assume that the valve is at the tire’s lightest point.
What is the dot on tires mean?
The “DOT” symbol certifies the tire manufacturer’s compliance with the U.S. Department of Transportation (DOT) National Highway Traffic Safety Administration (NHTSA) tire safety standards. The first two numbers identify the week and the last number identifies the year of manufacture.
Does China own Pirelli tires?
Pirelli Tyre S.p.A. Pirelli & C. S.p.A. is an Italian multinational company based in Milan, Italy, listed on the Milan Stock Exchange since 1922, with a temporary privatization period by the consortium led by the Chinese state-owned enterprise ChemChina. Pirelli is now solely a tyre manufacturing company.
What do the yellow and red dots on a tire 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.
What are the colored lines on new tires?
The stripes are there strictly for identification. It makes it easier to prevent mixups within the factory if you can quickly identify the tires. They are painted on the surface of the tread when the tread is extruded.
Why do tires have inside and outside?
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. These tires are usually simply marked, inside, outside, this side out, or like our example; mount this side out.
Is when the yellow dot is matched up with the RIM’s heaviest point?
The valve stem is theoretically the heaviest point around the rim. Therefore you “should” mount the tire so that the lightest point of the tire (yellow dot) is at the heaviest point on the rim (valve stem, especially metal ones) to minimize the imbalances inherent in the manufacturing processes.
What is road force balance?
Road force balancing, sometimes called ride matching, is the most effective way to diagnose and resolve runout or force variation vibrations. A road force tire balancer uses a load-roller to simulate the force of the road and gather the combined uniformity of a wheel and tire package. Learn more about tire balancing.
How do I know if my tires are DOT approved?
The DOT number is used for safety standard certification and also in the event of a tire recall by the manufacturer. According to current regulations, the DOT Tire Identification Number must begin with the letters “DOT” followed by a series of characters (usually 10, 11, or 12 numbers, letters, or symbols).
What is the oldest tire you should buy?
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…
How do I tell the age of my tires?
To determine the age of your tires, check the last four digits of the U.S. The U.S. Department of Transportation (DOT) number stamped on the tire’s sidewall contains a date code that identifies the age of your tires.
Are Pirelli tires expensive?
Our Final Thoughts on Pirelli Tires

Whereas Michelin has more to offer for the everyday use tyre, ideal for family and company cars.
How long do Pirelli tires last?
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.
