I have found aftermarket rims, which look exactely as the OEM bmw winter tyres.
Rim size is 8x18ET20.
Price for the 4 rims is EUR 650.
I can obtain also a package rims + tyres for EUR 1'440.
The tyres used is this package are :
235/40VR18 Michelin Pilot Alpin PA2
But the weigth factor is 91 for those tyres, OEM are 95. Is it very important to keep the original 95 weight, or can use also 91 for winter tyres ?
thanks for your input.
