Division 5.2

In the case of vehicles of categories M₁ and N₁, which are designed to be capable of towing a trailer, the additional load imposed at the trailer coupling device may cause the rear tyre maximum load ratings to be exceeded in case of class C1 tyres, but not by more than 15 %. In such a case, the vehicle owner’s handbook shall contain clear information and advice on the maximum permissible vehicle speed when towing a trailer, in any case not exceeding 100 km/h, and on the rear tyre pressure, at least 20 kPa (0,2 bar) above the tyre pressure(s) as recommended for normal use (i.e. without a trailer attached).
