Hi, I've got a Ford Galaxy 2011 Titanium 1.6 TDCi running on standard Ford alloys with 225/50R17 tyres. Whilst these are not super low profile, I still find there is too much road noise. Has anyone tried switching to the other option of 215/60/R16 wheels and tyres (I would buy Ford 16" alloys that were originally listed as an option for the Galaxy/S-Max) and have they noticed any difference in road noise and comfort ?
