Forestry tires have to deal with extremely difficult driving conditions. You tend to meet slippery rocks, bogs, swamps, steep hills, mud and even snow in the forest. Then you have sharp rocks and stumps that can easily damage the tires. The development has lead to very durable tires that can handle these conditions and even have very aggressive tread pattern that can excel in these conditions. Most tires can however still use tracks and chains if needed, as the design has taken this into account.
If you need chains on your harvester tires or your forwarder tires, will depend on the tires you have selected and the working surroundings that you will work within. If you do need tracks then you will need to make sure that you select the track type that fits the tire size and tread design. The tire pressure should be the maximum permitted inflation pressure for each tire size to ensure that you get the optimal traction between the tire and track to ensure best traction for the equipment. The tracks lower the surface pressure, which will be good for keeping the surface intact.
Chains are less common nowadays as the tires are so good, but you can still end up in situation where you will need to use chains. If the chains are new they should be checked to ensure that they are free from any sharp edges or welding burrs. If you find any sharp areas, try to remove them before mounting the chains. When the chains have been mounted make sure that they are fitted tightly, as loose chains can slip on the tires and cause damage and wear. When you check your tires for potential cuts or cracks, also check the chains that they are in good condition and that no chain rings are broken and that the rings are turned in the correct direction.
If you are planning to use chains or tracks with your tires, consult the technical tire manual to ensure that the tires are suitable for use together with tracks or chains. If they are, the correct tire pressure can be found in the manual, to ensure the best grip. When the chains or tracks are not needed any longer they should be removed, especially for the chains, as they are more aggressive on the surface.
