RADIAL TYRE Technology on Stronga Agricultural Trailers
At Stronga we recognise the customer is always the key to product development including every detail and component on our agricultural bulk trailers. Tyres are an often overlooked but vital component in the delivery of a high performance cargo trailer.
Rapid Increases in the size of tractors and bulk cargo trailers naturally leads to greater demands on the performance of tyres.
Add in the effects of greater speed and larger distances travelled and it is easy to see why lower specification tyres fail to cope with the demands made of them.

Country King Tyres enhance the performance of Stronga Bulk Agricultural trailers
Customers tell us they need long life and durable flotation tyres to manage both the increased weight of larger capacity trailers as well as minimising the compaction to the soil. On the road the tyres travelling at high speed under load need to offer good driving and braking properties.
Customers are more and more aware of the difference a good radial tyre can make to the overall performance of the bulk trailer in often rapidly changing conditions.
Stronga choose Nokian as our preferred supplier of modern radial tyres for agricultural bulk trailers for a number of reasons:

Hopefully professional users of our cargo trailer value the efficiency, durability, and user comfort these tyres offer.
Soil research has proven that compaction of soil by agricultural trailers can have adverse effects on crop production and a radial construction offers a flat even footprint whilst a cross-ply tyre, due to its construction, becomes dome shaped considerably reducing the contact area.
The structure of the redial tyre reduces rolling resistance which offers reduced fuel usage and cost saving.
Due to its structure, Nokian Country King Tyres perform well on fields while its self cleaning property reduces the risk to other road users. Nokian Country King, which has a block tread pattern which can reach speeds of 65 km/h and travels steadily and safely on the road.
