What do the 3 numbers mean on motorcycle tires?
Metric System
This system measures the size in millimeters. It is the most commonly used system for motorcycle tires, which is a set of three numbers and letters implying the width of the tire, the aspect ratio of the tire (ratio of tire’s height to the width) and lastly the rim size given in inches.

What does 67H mean on a motorcycle tire?
load and speed index
This measurement is inches rather than millimeters. The MC designates that this is a motorcycle tire, and the 67H is the load and speed index. A 67 load index means the tire has a 667 maximum load rating. The H speed index means the tire is rated at a maximum of 130 mph.
How wide is a 130 motorcycle tire?

What does 90 90 mean on a motorcycle tire?
ASPECT RATIO
This is measured as a straight line through the tyre from one edge of the tire’s tread to the other edge. THE SECOND NUMBER – ASPECT RATIO. The second number, the 90, represents how tall a motorcycle tire is in relationship to its width.
What does MT90 mean?
An alphanumeric designation such as MT90 17, represents the same tire size as 130/90 17. It’s just expressed in a different way. M means the tire is for motorcycle use, T is the tire width code, 90 is the aspect ratio and 17 is the rim diameter.
How does tire size affect motorcycle handling?
It’s always a balance of grip, handling, and wear. So, smaller, less powerful bikes can get away with smaller, narrower tires, while bigger, more powerful bikes require larger, wider tires so that they offer adequate traction and wear, but not so wide that it ruins the handling.
What is better bias or radial motorcycle tires?
Ultimately, bias tires are suitable for vehicles traveling at moderate speeds, with small to medium-sized engines and flexible chassis. They are also suited to heavy or heavily loaded motorcycles. Radial tires are needed for more powerful vehicles with very rigid chassis and for more sporty purposes.
What does the W mean on a motorcycle tire?
The “W” represents the maximum speed for the tyre when it is correctly inflated and being used under load, in this case 270km/h.
How wide is a 90 motorcycle tire?

What does 130 mean on a motorcycle tire?
In other words, the larger this second number is, the taller your motorcycle tire will be. For example, a tire that is written 130/90 means that it has a width of 130 mm and it is 90 percent as tall as the given width. When you calculate 90 percent of 130, that means it is 117 mm tall.
Is a wider tire better for a motorcycle?
Having a wide rear tire helps to prevent slippage in wet, rainy conditions. Wide tires provide a smoother ride. They are more capable of absorbing the bumps on the road. Wider tires are great because they provide help with power transfer and help handle stronger motorcycle engines.
Should I put radial tires on my motorcycle?
What does the B mean on a motorcycle tire?
bias belted
This is identifying the manner in which the tire was constructed, radial, bias belted, or standard bias/cross ply. Obviously, “R” stands for radial and the “B” stands for bias-belted. If there is no letter between the aspect ratio and rim size that means the tire is just a standard bias ply tire/cross ply tire.
What does B stand for on motorcycle tires?
Is it OK to increase tire size on motorcycle?
By making the back tire wider, you simply increase the surface area that comes into contact with the road. This translates to more traction which means enhanced grip and handling. The wider tires also dramatically reduce cases of slippage when riding on wet, rainy conditions.
How wide is a 90 tire?
How do I choose the right motorcycle tire?
The profile of a tire and the rubber compound chosen is based on the use of the tire. Generally, street motorcycle tires with a harder rubber compound get better gas mileage but don’t stick to the road as well. The softer the rubber compound, the grippier a tire is, at the sacrifice of gas mileage.
How many years are motorcycle tires good for?
The industry standard for replacing motorcycle tires is six years after their initial manufacture date. However, if kept in temperature-controlled storage, this shelf life may be extended a little. The National Highway Traffic Safety Administration (NHTSA) mandates that all tires include an identification number.
Which motorcycle tires last longest?
The Commander II developed a reputation for longevity, with Michelin claiming up to 25,000 miles for rear tires. In 2020, Michelin introduced the Commander III, adopting a new architecture and a more rounded profile while still claiming class-leading mileage.
What PSI should my motorcycle tires be?
28 to 40 psi
Typically, street motorcycle tires are in the 28 to 40 psi range. A label like this may be on the bike that tells you what tire pressures to use for different load conditions. Another factor is the anticipated load conditions and road conditions.
How often do you change motorcycle oil?
If a mineral-based motor oil was used, it should be changed around 2,000 miles. Semi-synthetic motor oil should be changed every 5,000 to 6,000 miles, while fully-synthetic motor oil only needs to be changed 7,000 to 10,000 miles.
How often should you change a motorcycle tire?
every 5-6 years
As with most consumables, tires have a shelf life. Motorcycle tire manufacturers advise that even if a tire has lots of remaining treads, the drying out of the tire’s multiple rubber compounds means it will need replacing every 5-6 years.
Are 14 year old motorcycle tires safe?
For the most part, you should avoid riding on tires that are more than ten years old. To determine if your motorcycle tires are too old, check their date codes. New motorcycle tyres are manufactured every six years. If you notice a tire that’s over ten years old, you should replace it.
