Full title and description

Off‑Road Tire and Rim Classification — Forestry Machines (SAE Recommended Practice J1440). This document establishes classification, terminology and representative construction details for off‑road tires and rims used specifically on forestry machines.

Abstract

SAE J1440 defines a standard nomenclature and classification system for tyres and rims intended for forestry applications, clarifies related terminology in common use, and illustrates representative component and construction details to aid manufacturers, OEMs and service personnel in specifying and matching tyres and rims for forestry machines.

Scope

This recommended practice covers classification and nomenclature of off‑road tires and rims designed specifically for forestry machines, provides definitions of terminology in common use within the industry, and shows representative construction details of component parts to support correct selection, matching and communication between tyre manufacturers, rim producers and equipment OEMs.

Key topics and requirements

• Classification codes and nomenclature for forestry/off‑road tyres and rims (establishes standard descriptions for LS/HF and similar designations used for logging/forestry service).
• Definitions of key terms used for tyre construction, service type and rim coordination.
• Representative construction details and component illustrations to aid specification and interchangeability.
• Guidance for matching tyre service classifications to typical forestry machine applications.

Typical use and users

Used by tyre and rim manufacturers, forestry machine OEMs, fleet managers and service/maintenance technicians to specify and document tyres and rims for forestry equipment, and by standards committees and procurement teams when writing equipment requirements or ordering replacement tyres and wheels.

Related standards

SAE J1440 cross‑references SAE J1116 (categories of off‑road self‑propelled work machines) for machine classification and is aligned in purpose with international tyre/rim documents such as ISO standards for logging/forestry tyres and rims (for example ISO 18807 and related ISO/TC 31 series documents). Users often consult the SAE J1116 categories and ISO tyre/rim standards when applying J1440 classification in practice.
