just the slightest bit more info for you,,this might do it,,
this is a brain out situation ,but,here goes guys,
ive got bikes,motorbikes,5 in all, sports to goldwings,and tyres and stuff is big news as we rely on them totally,
now,when you get a new tyre,theres a red dot on the wall,this shows the fitter that this is the lightest part of a tyre,this then should inform him that this red dot should marry up against the valve,as the valve on a wheel is a heavy item,then when the tyre is inflated ,you can safely balance the whole item perfectly,yes you can still balance a tyre with the red dot unmatched,but it takes more lead,and can cause the tyre to oscilate gently at speed as two weights are forced around,not perfectly balanced,this could cause a warped disc affect,which on a whole is not good for anything,bearings seals ,parts etc,
im a picky bastard but whoever fits my tyres,that i pay for,and dosent match the dot up,gets to fit and balence them again free.
