Which way do I orient my bike tire's tread direction? and why? What does the tire tread do? On a normal, smooth road, the tread has only limited influence on the riding properties. The grip generated by the tire on the road is almost exclusively the result of the rubber compound. Unlike a car, a bicycle will not aquaplane. The contact area is much smaller and the contact pressure is much higher.

Tire The valve stem is a tube made of metal or rubber, through which the tire is inflated, with a check valve, typically a Schrader valve on automobiles and most bicycle tires, or a Presta valve on high-performance bicycles.Valve stems usually protrude through the wheel for easy access.hen a wheel and tire rotate, they exert a centrifugal force on the axle that depends on the location of their center of mass and the orientation of their moment of inertia. This is referred to as balance, imbalance, or unbalance.

HOW OFTEN SHOULD I ROTATE MY TIRES? Tread is also part of what prevents a vehicle from hydroplaning (aquaplaning), or losing traction when gravel is present on the road surface. Ensure the safety of your vehicle and the safety of your passengers with regular tire rotation, tire tread depth checks and complimentary tire inspections.

Flat Tire Repairs There are many different rubber compounds used in a tire. The tire's innerliner uses a special rubber compound that has the ability to better retain air. Once punctured, the innerliner must be cleaned, buffed, cemented, patched and coated to assure its ability to retain air has been restored.

- 1 Heel/toe tire wear: This happens when one side of the tread blocks is wearing faster than the other side circumferentially. 2  When you run your hand over the tread blocks, they will feel like saw teeth. 3  Heel/toe wear typically occurs in a shoulder rib and is often caused by excessive positive or negative toe.owever, a variety of factors can cause a tire to wear out sooner than expected, and/or cause it to wear irregularly and create noise or vibration. Two common causes of early tire wear out and irregular tire wear are improper inflation pressure and out-of-spec alignment conditions.

Tread Depth The 20p Test. A quick and easy way to see if your tyre tread exceed the minimum legal tread depth is to take the 20p test. Simply place a 20p coin into the main tread grooves of your tyre. If the outer band of the 20p coin is obscured when it is inserted, then your tread is above the legal limit.n wet weather tyre tread grooves help to remove water from the contact patch between your tyres and the road surface meaning your car can brake, steer and accelerate properly. Without adequate tread depth your tyres may not be able to perform properly in wet conditions, reducing your safety on the road.

- This type of wear usually results from consistent under inflation. When a tire is under inflated, there is too much contact with the road by the outer treads, which wear prematurely. Tire pressure should be checked with a reliable pressure gauge.

How does TPMS work? If you drive a newer car, you probably have what's called a Tire Pressure Monitoring System (TPMS) installed. TPMS is an electronic system inside the tire that monitors the air pressure in your tires. If your tires are under- or over-inflated, the TPMS activates a warning light on your dashboard. When the light is steady, it means you need to have your tire pressure checked.

- Tire mark striations are direct physical evidence of the direction of the force that was applied to the tire at the time the mark was deposited. Without braking, the tire force is perpendicular to the tire heading, and thus, the striations produced are perpendicular to the tire heading.ext, consider the effects of braking on tire mark/tire geometry. Figure 6 depicts three scenarios; a free rolling tire on the left, partial braking in the center and full wheel lockup on the right. The vertical line in each scenario, which is aligned to the tires velocity direction, has a dimensionless length of 1.

- A tire tread pattern made of raised rubber compound segments. Bolt Circle: Sometimes referred to as bolt pattern: The number of lug holes on the diameter of the imaginary circle that each lug hole is centered on. Carcass: The portion of a tire that is the foundation for the tread, belts, bead and sidewall. Casing: The structure of tire cords locked around wire beads. Compound : The general term referring to the chemical formula for the tread material. Criss-Cross Torquing

- First, visually examine all 4 tires; second, feel the tread by hand to detect wear such as feathering and third, check all 4 tires with a pocket type pressure gauge. Over Inflation. Excessive wear at the center of the tread indicates that the air pressure in the tire is consistently too high. The tire is riding on the center of the tread and wearing it prematurely.

- It really is how the tires are designed. The steel mesh belts and material layers are laid in a way that makes each layer work together to make the tire stronger based on tire rotation. Reversing this rotation applies pressure in the wrong direction and unravels this tight mesh that made the tire so strong.

- The way your tires wear is a good indicator of other parts of your car. Abnormal wear patterns are often caused by the need for simple tire maintenance, or for front end alignment. Tires should be inspected at every opportunity; once a week isn't too often.irst, visually examine all 4 tires; second, feel the tread by hand to detect wear such as feathering and third, check all 4 tires with a pocket type pressure gauge.

How Tire Pressure Monitoring Systems Work How Tire Pressure Monitoring Systems Work. If your light goes off, it's a good idea to check your tire pressure as soon as possible. Direct tire pressure monitoring systems use individual sensors inside each tire, and sometimes a full-size spare, to transmit information to a central control module. The sensors read internal pressure, and sometimes temperature.

How Tire Pressure Monitoring Systems Work Sensors within the tire, or on the car, send information to one or several modules in the car. These modules are programmed with a range of acceptable circumstances. For direct tire pressure monitoring, this is often between 28 and 35 pounds per square inch (psi) of air in the tire.

- With a tire tread depth gauge. Tire tread depth gauges are a fast and easy way for you to know for sure if your tires are safe or if they need to be replaced. 1  Find the shallowest groove of the tread and insert the pin of the gauge until the base is flush with the tire.  Read the scale.

H/T Vs. A/T Tires H/T tires use specialized tread grooves, rubber compounds and internal structures to reduce rolling resistance. Rolling resistance is a function of how well the tire grips the road. High rolling resistance makes for more traction but worse fuel economy; lower resistance does the opposite.

- Tire pressure should be checked with a reliable pressure gauge. When this type of wear occurs, and the tire pressure is known to be consistently correct, a bent or worn steering component or the need for wheel alignment could be indicated.Bent steering or idler arms cause incorrect toe-in and abnormal handling characteristics on turns.irst, visually examine all 4 tires; second, feel the tread by hand to detect wear such as feathering and third, check all 4 tires with a pocket type pressure gauge.

- Mechanical engineer working in automotive here. Car tire treads move water from the center of the tire to the outside edges. Many but not all motorcycle tire treads do the opposite, taking water from the outside edges and moving it towards the center. Sometimes the front and rear have opposite thread patterns.

Tread Depth There are several popular ways to check your tire tread depth. One easy way is the penny test. Simply insert a penny into your tire's tread groove with Lincoln's head upside down and facing you. If you can see all of Lincoln's head, your tread depth is less than 2/32 inch and it's time to replace your tires. Another easy coin test is the quarter test. Insert a quarter into your tread groove.
