Nokian introduces 24-ply forestry tyre

ERJ staff report (DS)

Nokia, Finland -- Nokian Heavy Tyres said it has introduced the world's strongest forestry tyre customised for CTL (cut-to-length) tree harvesters. Nokian said its Forest King F 710/45-26.5, a revolutionary, sturdy cross-ply novelty from the pioneer in forestry tyres, and offers the best available reliability and load-bearing capacity for modern harvesters and forwarders.

The company said The Ply Rate (PR) describes the durability of this special tyre, tailored for demanding forest use, is 24. Forestry tyres currently available on the market typically have a PR figure of 16 or 20. The load-bearing capacity of this product has increased by more than one tonne, from 6,900 kg (Nokian Forest King F 20 PR) to 8,000 kg (the new Nokian Forest King F 24 PR).

In six- and eight-wheeled forestry machines, said Nokian, this increase in load-bearing capacity corresponds to some 4 cubic metres of pinewood harvested in the summer. Thanks to increased reliability, full loads can also be safely transported despite of the tree species or humidity of the wood.

The product coincides with the launch of a new range of forestry tyres from Nokian under the Nokian Forest Rider range.

As a result of the larger contact area, the Nokian Forest Rider has a lower surface pressure than a cross-ply tyre, ensuring that the tyre does not sink in terrain with poor support. It is gentler on both growing trees and the driver, in addition to dampening vibration and offering better driving comfort during long days typical of forestry work.

The Nokian Forest Rider, used in CTL forestry machines and heavy tractors is manufactured with tubeless construction (TL=tubeless).
