Quick Answer: How do you measure motorcycle tire wear?

How do you read a motorcycle tire wear indicator?

To check your motorcycle tyre’s tread depth, inspect the built-in wear indicator bars (if there’s any) in your tyre tread. If the bars are no longer visible, replace your tyres. For tyres marked only with a Tread Wear Indicator on the sidewall, simply check if the tread is on the same level as the TWI.

How do you gauge motorcycle tire treads?

On motorcycle tires, measure the tread depth in the center of the tire at several places. The lowest measured depth is the true indicator of the remaining tire life. There are two common methods used to measure tread depth—the coin test and tread depth gauges.

How do you calculate tire wear?

Penny Test for Tire Tread Wear Measurement

Insert a penny into your tire’s tread groove with Lincoln’s head upside down and facing you. If you can see all of the head, your tire tread depth is less than 2/32 inch and it’s time to replace your tires.

What is the right air pressure for motorcycle tires?

Legally the tire has to be changed accordingly to the national law. METZELER recommends changing tires once the tread depth is below 2mm. The below tire pressures are a range which depends on riding style, bike set up, and track conditions. For example 30/35 means pressure range is 30 to 35 psi.

Why is my motorcycle tire wearing in the middle?

Tire wear can indicate a number of issues. For instance, if the center of the tire is more worn than the edges, the tires may be over inflated. Conversely, underinflated tires will have worn edges. When your tires are underinflated, make sure to keep an eye on the pressure when you refill them.

What is a good tread depth for motorcycle tires?

Federal and state regulations dictate that you must have 1/32″ to 2/32″ of tread depth. The middle of the tire sees the most contact with the road and usually wears out first. We can measure your tread depth for you or you can check your wear indicators.

How much tread is on a new motorcycle tire?

UK law demands a minimum tread depth of 1mm across ¾ of the tread pattern with visible tread on the remaining ¼ for bikes over 50cc. Under 50cc requires all the grooves of the original tread pattern be clearly visible – if any grooves have worn smooth, your tyre needs changing.

Where is tire depth measured?

The best way to measure your tread depth is to stick the probe into the shallowest groove on the tire, press the shoulders of the probe flat against the tread and then read the result. All gauges should measure both in the 1/32″ United States standard and in millimeters.

Is it normal for motorcycle tires to lose air?

Tires naturally lose air over time

Since tires are the only thing between you and the pavement, it’s important to keep an eye on the PSI levels regularly. If you are a daily rider, strive to check your tire pressure weekly, and top off as necessary. If you aren’t riding quite as regularly, check it before every ride.

Why do motorcycle tires lose air pressure?

A motorcycle tire naturally loses some of it’s air pressure because of a process called osmosis (also known as permeation). This means that air has the ability to pass through the rubber particles of the tire at some point, similar to how helium and air escapes a balloon over time.
