MR Community - I've come to the point where I need a new set of tires - my first new set of tires ever (lived in Chicago for years and didn't need a car) - and haven't really been able to find clear and specific information on what's best. I currently have a 2010 Ford Focus SES with Kumho SOLUS HK16 P215/45R17 tires. They're what came with the (used) car. My dealer quoted a new set of 4 including all installation/disposal/taxes at $626.68. I went to a local Belle Tire (big chain mostly in Michigan) that dissed the tire for its type/size for my car and they recommended two sets of tires, one being a set of Continental 225/45Rs (pretty sure this link is them) for out the door pricing of $550. (For the record, the second set just had a 40,000 mile tread warranty on them and the Continentals had 65k - I drive a lot so I am leaning that way) I noticed on the door panel that the listed tire dimensions on my driver's door panel states: Tire (FR): P215/45R17 Tire (RR): P215/45R17 Pressure (FR): 240 kPa/35 PSI COLD (RR): 240 kPa/35 PSI Does that mean those tires would be too wide for my car? Or are those just suggested dimensions and not maximum? Every tire buying site that asks you to enter your make/model and pair tires to my info doesn't pull up 225s, so I was a little leery. I did like the sound of those tires though (and saving a bit of $ doesn't hurt either).
