My '07 reg Galaxy Ghia currently has 17inch rims with 225/50ZR17 98W tyres. I find the ride to be quite harsh on typical roads. It needs new tyres so I'm thinking of replcaing the 17 inch rims with 16 inch rims so that I can fit higher profile tyres to give a more cushioned ride.
I'm not bothered about handling, just ride comfort and I think that higher profile tyres give more air and sidewall rubber between me and the road.
Does anyone know what the critical factors are when changing rim sizes - I've checked the handbook and 16 inch rims were an option when new, but I don't know much about rims, offsets, stud patterns etc. Would 16 inch rims automatically fit over my brake calipers? I'm presuming they would because, as I say, 16 inch rims were an option. I just want to be sure before I buy rims that don't fit or have other problems.
