Why are dirt bike tires different sizes?

Can I replace my bike tires with a different size?

Bicycle wheels can handle a range of different widths, so it’s not absolutely necessary to replace your tires with one with the exact same width. In fact, there are often advantages to using a tire that is a little wider, as long as your bicycle has adequate clearance to handle the larger size.

Can tire sizes be changed?

It’s possible to change the size of your tires without actually changing the diameter. Generally, you don’t want to go with tires that have a diameter that is more than 3% different from the factory tires. It’s also a good idea to consult with a trusted mechanic before switching to larger or smaller tires.

Dirt Bike Tire Measurements. Dirt bike tires are commonly measured by in millimeters by Width / Aspect Ratio x Rim Diameter (inches). For example, on the tire size above, the aspect ratio is 90% of the tread width (the first number in the tire size), creating a 99-millimeter sidewall height.

Why do off road bikes have 18 inch wheels?

Pros of 18-Inch Tires If you’re going off-road, then they might not be the best choice. Getting 18-inch wheels allows the engine to propel your bike over rough terrain, pushing over obstacles that might otherwise prove difficult. Note that the ride might be a bit bumpier than if you had larger tires.

Does the width of a bike tire matter?

While tire diameter should be an exact match, you do have the option of putting on a tire with a slight variation in width. Some riders opt for wider tires, for example, to give them more traction and a somewhat cushier ride.

Is it OK to change tire aspect ratio?

Generally, the worst issue you will cause by changing the size is an inaccurate speedometer. That said, the only dimensions you can change are the width and aspect ratio — never the wheel size, unless you buy replacement wheels — and you should always strive to keep the total height of the tire the same as the OEM.

How long does a dirt bike tire last?

Tire Age. You should replace the motorcycle tires if they are over five years old. However, this is a general guideline to follow, and it does not apply to all situations. You may be able to use tires that are older than five years if they sat in storage for the first one to three years without extensive damage.
