The contact area of six different tyres was measured as a function of the tyre inflation pressure. In all tyres, a decrease of the tyre inflation pressure led to an increase in contact area. The tyre inflation pressure at which the contact area increases the most depends on the type of tyre used. A new equation was established in order to calculate the contact area on the basis of tyre size, tyre diameter and inflation pressure. This equation was calculated by means of multiple regression.

Sowing oilseed rape with other plants reduces damage caused by adult flea beetle, according to a study conducted at Agroscope. This intercropping approach could limit reliance on insecticides and the emergence of resistant pests.
