|---|---|---|---|---|
| 700x35c | 35 | N/A | 700 | The “c” in “700x35c” refers to the tire’s casing construction, indicating a classic or traditional tire design. |
Motorcycle Tire Width and Aspect Ratio
Tire width and aspect ratio are key to a motorcycle’s performance and comfort. Knowing these specs helps you pick the right tires for your bike.
The width of a motorcycle tire is measured in millimeters (mm) or inches. It ranges from 90 mm for small bikes to 240 mm or 300 mm for big cruisers. A 130 mm tire is about 5.1 inches wide.
Aspect ratio is the sidewall height to tread width ratio. It’s shown as a percentage, like 60 or 180. A 180 ratio means a short sidewall and a “square” profile. A 60 ratio gives a tall sidewall and a “round” profile.
| Tire Width | Aspect Ratio | Characteristics |
|---|---|---|
| Narrow (e.g., 4.10, 130 mm) | High (e.g., 60) | Increased cornering stability, reduced comfort |
| Wide (e.g., 180, 200, 240 mm) | Low (e.g., 180) | Improved traction and stability, increased comfort |
Choosing between narrow and wide tires, or high and low aspect ratios, depends on your motorcycle’s use. Sport bikes do well with narrow, low-aspect tires for better handling. Cruisers and touring bikes prefer wider, higher-aspect tires for more comfort and stability.
“The widest motorcycle tire available is typically around 300 mm, though this is primarily seen on large-displacement cruisers and touring models.”
Understanding tire width and aspect ratio helps you pick the right tires. This will improve your motorcycle’s performance and give you the ride you want.
Motorcycle Tire Size: Impact on Performance
The size of your motorcycle’s tires greatly affects its performance. It impacts handling, cornering, traction, and grip. Choosing the right tire size can change how your bike handles on the road.
Handling and Cornering
Tire width is crucial for handling and cornering. Are wider tires better on a motorcycle? Yes, wider tires usually mean better stability and cornering. They give a bigger contact patch with the road, which helps with grip and control in turns. But, be careful not to choose tires that are too wide, as they can make the bike feel heavy and less agile.
Traction and Grip
Can you put any width tires on the same rim motorcycle? No, the tire width must match your motorcycle’s rim size. The right tire-to-rim combo is key for good traction and grip. Tires that are too narrow may not grip well, and those that are too wide can cause instability and wear out fast. What does 72h mean on a motorcycle tire? The “72H” speed rating tells you the top safe speed for that tire.
Can i put a different size tire on my motorcycle? You might be able to try a different size tire, but check with your bike’s maker or a pro first. They can tell you if the new tire size will work with your bike without hurting its performance or safety.
| Tire Size | Handling and Cornering | Traction and Grip |
|---|---|---|
| Wider Tires | Increased stability and improved cornering | Larger contact patch, better grip |
| Narrower Tires | Less stable, less responsive in turns | Reduced contact patch, potential traction issues |
