I have had my 2007 C70 for over a year. I have about 30k miles on tires and have regular rotated and had car aligned. I put car on lift and looked at tires and have wear to the wear bars on front and very uneven wear on inside part of tires on rear. I can understand these tires not having good wear but I was suprised of the uneven wear which seems suspension, alignment related (tire pressure in fine). I am faced with buying 4 tires and the originals are MichelinPilotHX MXM4(235/45/R17) and since the care has no spare, I am stuck having to find run flat replacement tire but I am not impressed with these tires (also pricey at $200+ ea.). Does anyone know of a good alternative RFT?
