I am going to need to replace the tires on my S60 at some point in the not to distant future, and am trying to decide what to go with. My car currently has the OEM Eagle RS-A2 tires on it. Tire rack has this tire on sale for $114 right now. The other option I am considering is the Primacy MXM4. This tire is currently priced at $280. I like the idea of going with a low rolling resistance tire, as being a 60 owner, every mile of range I can pick up is important. Improved winter traction and tread life would also be nice to have. Is there anyone here who has had both of these sets of tires on their car, and can tell me their opinion on if the MXM4 with worth more than 2x the price?
