NOKIA, Finland, November 23, 2010 - Nokian Heavy Tyres introduces the world's strongest forestry tyre
customised for CTL (cut-to-length) harvesters. Nokian Forest King F
710/45-26.5, a revolutionary, sturdy cross-ply novelty from the pioneer in
forestry tyres, offers the best available reliability and load-bearing
capacity for modern harvesters and forwarders.

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 stable, unparalleled first-class 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, 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 efficiency requirements of modern forestry tyres have increased year
by year. In addition to environmental friendliness, machine manufacturers and
contractors are looking for products that feature high quality and
increasingly better load-bearing capacity and traction. Our new, carefully
developed, ultra-strong material solutions enable a durable structure, higher
operating pressure and first-class load-bearing capacity. The new Nokian
Forest King F is the best of its class, offering all the desired features,
ensuring reliability and making harvesting easier than ever before," says
Martti Paivinen, Product Development Manager at Nokian Heavy Tyres.

Safe and efficient working hours

Featuring excellent grip, the Nokian Forest King F is one of the world's
best-selling forestry tyres. The lightly and effortlessly moving first-rate
product performs its job efficiently, showing respect for the environment.

The wide tread, strong at the shoulders, provides forest machine
contractors with many safe working hours in a variety of harvesting tasks.
Thanks to the wide tread, the tyre's contact area is larger, which lowers the
surface pressure. The big contact area and low surface pressure ensure that
the Nokian Forest King F treats growing trees and sensitive undergrowth

The straight sidewalls efficiently prevent damage to the sides. The
groove profile, which deepens on the shoulder, and the straight tyre sidewall
work together to increase the tyre's superb cleaning properties and

The design of this extremely reliable tyre supports the position of
tracks and chains, ensuring that they fit optimally on the tyre. Tracks stay
well in place and work excellently in wet conditions, where grip is poor.

Front-runner in environmental matters

Nokian Heavy Tyres is a pioneering tyre manufacturer in environmental
matters. It was the first tyre company in the world to abandon harmful oils
in its production processes and to use only purified oils.

Environmental friendliness is a key principle in our R&D philosophy. The
rubber compounds, treads and structures of special tyres withstand wear and
tear, which, from the users' point of view, translates into many operating
hours and functionality. The lightly rolling tyres also reduce fuel
consumption and carbon dioxide emissions. Continued reduction of tyre
vibration and noise is another challenge for product development.

Nokian Heavy Tyres Ltd is part of the Nokian Tyres Group. The company's
product range includes forestry tyres, special tyres for agricultural
machinery and a variety of industrial machinery tyres used in, for example,
harbours and terminals, underground mines, earthmoving and road maintenance.
