What is BS AU 50-1.7.1 - Designation, dimensions, and load ratings for moped tyres about?
BS AU 50 is a series on tyres and wheels. Tyres and wheels are ring-shaped components that surround a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels.
BS AU 50-1.7.1 establishes the designation, dimensions, and load ratings for moped tyres.1) ISO 5995-2 will deal with requirements for rims.2).
Who is BS AU 50-1.7.1 - Designation, dimensions, and load ratings for moped tyres for?
BS AU 50-1.7.1 on designation, dimensions, and load ratings for moped tyres is useful for:
- Tyre manufacturers
- Design engineers
- Quality control personnel
Why should you use BS AU 50-1.7.1 - Designation, dimensions, and load ratings for moped tyres?
Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Some tyres of similar size designation and dimensions to those shown in BS AU 50-1.7.1 but with different performance capabilities are manufactured.
These tyres are designed for a maximum speed of 100 km/h have the differences which include the word “MOPED” or “CYCLOMOTEUR” or “CICLOMOTORE” is not marked on the tyre sidewall, the service characteristics indicating the “LOAD INDEX” and the “SPEED SYMBOL” may be marked on the tyre sidewall, the load capacities and relevant inflation pressures appropriate to a maximum speed of 100 km/h, are shown in 7, the load capacities of Table 7 can be increased by up to 30 % when the above tyres are fitted on mopeds (max speed 50 km/h) designed for carrying an additional passenger. Using BS AU 50-1.7.1 you can establish the designation, dimensions, and load ratings for moped tyres.
