BS ISO 18807:2019

What is ISO 18807– Tyres and rims for logging and forestry service about?

ISO 18807 provides methods and procedures of manufacturing and testing tyres and rims used by heavy-duty vehicles in forest services and for logging.

ISO 18807 provides specifications on the marking, the tyre size designation, the dimensions, the load ratings and the rim coordination for logging and forestry service tyres in diagonal and radial construction.

Who is ISO 18807– Tyres and rims for logging and forestry service?

ISO 18807 on tyres and rims for logging and forestry service is relevant to:

• Manufacturers of tyres
• Manufacturers of heavy-duty Automobiles such as trucks
• Mechanical engineer
• Forest department

Why should you use ISO 18807– Tyres and rims for logging and forestry service?

'Rims' are cylindrical wheel edges that hold the tire to the wheel. Their main function is to support and seal the tire to the wheel. They ensure a proper fit between the tire and the rim and retain air inside the tire.

In tyre manufacturing, ISO 18807 lays out general methods for producing cross-sectional markings and sizes for metric-measured tyres to carry out transportation services, to increase load capacity, and to prevent damage to tubes of tyres, which can also be applied to logging and forest services.

ISO 18807 covers all significant requirements, methods and is used to manufacture logging vehicles tyres.

ISO 18807 is an important guide for manufacturers to provide a comprehensive understanding of quality tyres so that they can minimize the chance of tyre failures leading to mechanical breakdown and perform well in any type of terrain.

What’s changed since the last update?

BS ISO 18807:2019 supersedes ISO 4251-5:1992, which are withdrawn and includes some technical changes concerning the standards it supersedes:

• information already contained in other International Standards was removed and replaced with normative references to those standards
• data for tyre sizes with metric designation was added
• the document was aligned with other standards developed by SC 5 and with existing regulations
• additional definitions useful for the comprehension of this document were added
• the pictogram to identify the maximum pressure for tyre bead seating, as specified by UN/ECE Regulation 106, was introduced
• dimensional data and the list of approved rim contours were revised
