Hello I must first emphasize that I have the vehicle for which I have questions, only get in about 6 – 8 weeks. Chassis number ZFA2500000….. K: e13*2007/46*1237*09 Tires 225/75R16 C Question 1: ==== With which 16″ steel rim (technical data) will the Fiat Ducato Maxi 40 H, production Bj 2019. 1. HJ from Fiat be delivered as standard? About https://www.oponeo.de/… For example, 7.5Jx16H2 ET35 Question 2: ===== What load does this rim have? In the case of tyres, the load is indirectly the load index on the tire. For example, 225/75R16R 121… 121 = 1.450 kg I have not found similar for rims on the internet. Where and in what form (e.g. load index for rims) is the load on the rim? I would be happy if someone could give me information.
