Key 2026 Updates

Passenger Tyres

Growth continues across multiple segments:

•  Metric Radial Ply – continues to grow slowly but steadily, particularly in the lower profile and high-performance ranges
•  “HL” (High Load) Radial  – a relatively new range that is expanding quite rapidly as  Vehicle Manufacturers can utilise existing tyre size envelopes but with a greater load Capacity.  Low-profile high-performance sizes are growing quite rapidly.
• P Type Radial Ply sizes have been relocated to the Supplementary Data Section at the back of the Manual as Obsolete Data.

Radial Light Truck

• Ongoing strong growth in Metric Normal Highway and High Flotation ranges.
• Expansion is most notable in larger sizes.

 Metric Radial truck

• A limited number of new sizes were introduced in Normal Highway and Free Rolling service.
• Aside from selected trailer applications, this segment remains largely static.

 Agricultural Tyres (Metric Radial Ply)

• New drive wheel sizes approved, particularly for harvesting applications.
• Introduction of a new range of Metric Implement tyres.
• Expansion of IF (Increased Flexion) and VF (Very High Flexion) sizes to support growing demand.

 Industrial Applications

• Addition of a small range of solid tyres for use on pneumatic tyre rims in counterbalanced lift truck and skid steer service.

 Motorcycle Segment

• Additional sizes were introduced across both diagonal and radial constructions.
