Hello, I’m just writing this now because I’m relatively baff (so astonished) and wanted to know if there was someone out there, in the expanses of the Internetze, for whom this is an “old hat”: We bought 16 inches of Magma aluminium rims for our new Skoda 6 (type Celsio). After the assembly, the tires stood two days in the workshop before the vehicle was to be re-tired. At the same time, one tyre had less pressure (2.0 instead of 2.6 bar) than the rest. Venti tested t, without any findings, air was refilled and observed since it was suspected that maybe too little was filled in. But after 2 days there was too little air in it again. Then we started to examine the wheel and when we just threw the whole part into the water the culprit revealed himself: the rim has a microfine hole in one place … at the material strength one has to speak more of a channel, through which the air flows very slowly. s has never come under me so far and therefore the question: to you perhaps? Greetings Matthias
