time for tyre testing

New technology can carry huge loads at low pressure
Regardless of how advanced a modern agricultural tractor may be or the technology used in its design and construction, almost all need tyres to transfer this power into work.
Many owners put no more thought into tyres than the fact they are black and, unless punctured, round.
Tyres, though, are a crucial element of any agricultural tractor, particularly those involved in tillage operations. Even though they are still black and round, tyre technology has come a long way.
A decade or two ago, there would rarely be a tillage tractor in sight without a set of dual wheels to carry the corn drill or harrow. The horsepower and size of the average tillage tractor have been steadily creeping up over the years, but it is far rarer to see a set of dual wheels on anything. Tyre technology has advanced to the point where tyres that are not overly large can carry huge loads at quite low pressures.
Many modern tyres have the ability to carry heavy loads without causing the level of compaction that will damage the structure of the soil beneath it and reduce crop yields. All strive to create a large footprint, so as to spread the tractor and implements' weight over a greater area.
A big footprint, combined with as low a tyre pressure as possible permitted by the tyre manufacture, reduces the negative effect on soil structure.
Tillage farmers and contractors tend to be more conscious of the various tyre options out there, primarily because of the impact of the use of heavy kit.
