The 17'' tyres are only permitted up to the gross weight of max. 2500 kg. This is due, among other things, to the load index of the tyres. However, the constellation "90-package + 2,800 kg load increase" should be pointed out by the selling dealer during the consultation. If the caravan is factory-fitted with a load-capacity of 2,800 kg, it will only be delivered with 195/70 R14 C tyres with a sufficient load index of at least LI 98 (load 750 kg).
