In checking around on the internet, looks like the cheapest available for the Pirelli P7 RFT 225/50/18 is $265. Not bad, actually.My X1 will soon be 3 years old and the tyres need replacement soon. The originals are Pirelli Cinturato 225x50x18 RFT. Any recommendation for a shop with reasonable price. Also any advice on other brands of RFT eg Bridgestone, etc. Thanks in advance.
