Motorcycle tyre markings provide important information about the tyre's size, type, construction, and performance characteristics. These markings are important when you are purchasing tyres online in Sri Lanka. Here is how to read them when getting tyres and tubes online in Sri Lanka:

1.     Tyre Size

·       The tyre size is typically marked in a format like 120/70 ZR 17. Here's what each part means:

·       120: This is the tyre width in millimetres.

·       70: This is the aspect ratio, which indicates the height of the sidewall as a percentage of the width. In this case, the sidewall height is 70% of the width.

·       ZR: This indicates the tyre's speed rating and construction type. "Z" means the tyre is capable of high speeds, while "R" denotes radial construction.

·       17: This is the diameter of the wheel rim in inches that the tyre fits.

·       Note that tyre prices in Sri Lankawill vary according to size.

1.     Load Index and Speed Rating

·       After the size, you might see a number followed by a letter, such as (58W).

·       58: This is the load index, indicating how much weight the tyre can support. Each index number corresponds to a specific load capacity (e.g., 58 means 236 kg).

·       W: This is the speed rating, indicating the maximum speed the tyre can safely handle. Different letters represent different maximum speeds (e.g., W = 270 km/h).

 

2.     Tread Pattern and Type

·       Some tyres for sale in Sri Lankawill have markings that indicate whether they are suited for certain conditions or types of riding:

·       Tread Pattern Codes: Some manufacturers include codes that represent the tread design or suitability for wet/dry conditions.

·       Type of Tyre: Look for markings that indicate whether the tyre is for street use, off-road, touring, sport, etc.
