No they don't, they will/should phone when a set of refurbs arrive at the garage. You take your car and they swap the wheels and tyres over( they did'nt have the facility to do this at my local dealer so they took the car to a garage that they deal with).
Its no hassle and besides if you stick them on ebay someone who knows a bit about these cars will ask you if they are blistered
My advice.......get them done buddy
