Hello together, I have registered a flat foot with my Alfa-Oldtimer with horror this morning. Wheel removed and can find no damage to the (quasi new) tires. So the old-school method used: tires pressed under water and looked for bubbles. And these rose up at the valve edge, so not from the valve opening but between the aluminium rim and valve socket (rubber). Now I think about how to get this close again. If the first possibility to the workshop would be f ahren – tire dismantling – valve disassembly – new in – tires again – balancing – finished. Is of course time-consuming… Maybe it also brings something to empty the tire – valve seat a little shaking – re-pump and hope that it does something… do you think that could work? Or breakdown spray…? I have never had such damage and therefore have little idea how the valve is sitting in there. Are old aluminium wheels and there it is of course possible that the seat is no longer so one hundred percent plan is… Best greeting, jo
