i had the tyres changed earlier this week on my 2009 RT. Yesterday the rear was flat, pumped it up and went down again. The tyre fitter told me it was leaking around the valve and that it needed a replacement seal kit. Also the external wheel surface has some slight bubbling/corrosion and it might need to be re-coated. Anyone familiar with this problem. The wheel internal surface is an unknown until we get the tyre off, but can’t do that until I have the new seal kit so it’s over to Shipley!! How to waste a Friday !
