Usually it's pretty tough to beat the prices on
www.tirerack.com. Your TPMS sensors are more expensive than most, but still with sensors and Pirelli Scorpion winters mounted on 17" alloys it's $1,671 USD. For the cheapest option (16" alloys with crappier tires) it's $1,375 USD. Those prices are with shipping/duty/mounting/balancing included.
