Hi guys, I changed wheels yesterday at my omi, winter bikes down, summer bikes on it. I noticed during the assembly, that in a pneumatic a screw is in the tread. This must have been raced in there already before the last change, because the screw head, it looks like a spax screw, is already a bit sucked off. But the tire has kept its tyre pressure throughout the whole winter. I am not sure now if I have the screw so If I drive to a tyre dealer then he immediately smells a fat business and wants to sell me two new tyres, only for that I don’t have any money right now. Maybe you can give me a hint what to do. Greetings Dick Uncle
