Hi guys, I’m looking for the minimum tyre size for my trailer. At the moment 155/R13 is on. So I have the loading edge to Höch, I want to screw on smaller tyres. From Achs manufacturer I have only one table with Dyn tire size dyn Rmin 0,21m and Dyn tire size dyn Rmax 0,30m The TÜV and also the tyre dealers near me nothing to start with. Have attached the pdf file from the axle manufacturer.
