NOKIAN FOREST KING F2

TRACK GRIP FOR DEMANDING FORESTRY USE

Find a dealer

SPECIALLY DESIGNED FOR TRACK USE

Nokian Forest King F2 provides tested, better track grip for demanding forestry work. Designed especially for tracks, Forest King F2 complements even the heaviest of forestry machinery.

Designed for tracks

During product development, special attention has been paid to making the tire work well with tracks. The traction between the tire and track has been improved by increasing the straight section of the ribs and the grooves on the centre part. Together with the shape of the shoulders, the new pattern improves support for the tracks and helps them stay on.

Reduced stress

Nokian Forest King F2 tire offers perfect track support at every point, keeping the track crossbars straight on the surface of the tire. The track does not need to be so tensed, which reduces the stress on the tires and bogies.

Improved puncture resistance

The puncture protection of Nokian Forest King F2 tire has been improved by increasing the material strength on the tire shoulders. This makes it ideal for demanding forestry work.

NEW TIRE SIZE FOR THE HEAVIEST FORESTRY EQUIPMENT

For Nokian Forest King F2 family, the rim diameter has been expanded to entirely new tire size of 28.5 inches in order to handle the increased pulling power of machines and to prevent the tire from spinning on the rim. This allows high load-bearing capacity without increased inflation pressures. The new tire size is a reliable solution for the heaviest forestry machines weighing over 20 tonnes.

Tire safety

Tire pressure entails a serious risk of explosion, the highly powerful tire machines impose danger, and working with tires also features a number of other health risks. The most important thing is to recognise risks in advance and act efficiently to control them.
