Hello, I bought for my Citroen C4 (3001/AKX) new summer tyres and rims. There are 17 inch rims from Alutech (ikenu metal grey), the report I also have and is also approved for my car, all good. The problem is that on the report stands the following for the fastening material: flat-bunded screws serial screw M12x1,25 for aluminium wheels tightening moment 100 Nm shaft length: 36 the problem is, 36mm is extremely rare, can that be? I have on the internet on the kfzt eile24 page (Berlin) found 35mm, but as far as I have read, 1mm should be longer than 1mm shorter, and with me would be 35mm 1mm shorter. Do I have to go to Citroen? What can I do here? Thank you
