Hi everyone I am Seat Ateca owner living in Ireland originally from the uk and I am the very happy owner of 2018 Xcellence 2.0tdi 4drive 150hp manual in cappuccino beige. I was just want a bit of advice with something, I have 18inch performance machined alloys currently on 225/50/18 Bridgestone tyres which now need changing after 26k I have been told I can put on 215/50/18 on the same rim by a tyre fitter just want to know if this is possible as not sure of this?
