Hi Guys
Talked to our Michelin tyre Guru this is the way to go, clean in side of rim with a soft copper wire brush leave tyre in sun. For those of you that don't get any sun move or take the tyre on holiday with you ,In the UK try Halfords ,its car windscreen wash and it has a small amount of drying alcohol in it Fit tyre to the rim ,spray all over, have tyre valve out, pump up fast ,tyre will pop on don't go over 30 psi as this stretches the cords in the tyre. This stops tyre slipping off when in water or hitting big rocks . This has worked for me over many years ,don't use water with the windscreen wash.
Cheers Wakka
