I was at Costco today for some bits and bobs and looked again at tyre prices, should my R come with RE050s. To my surprise, most of the tyre prices are up 15-20%, the 225/40 r18 PS3s are about £130 now from £108, and they want just over £200 a corner for 235/35 R19 Supersports. I mentioned to the fella who got those prices that they were nowhere near competitive any more and asked if they would fit tyres bought elsewhere, for a fee. He said they wouldn't, but could almost certainly authorise a price match with the likes of Black Circles after looking on Black Circles website, which would also include fitting.
