Plan to ditch the worn out, teeth-rattling, narrow-walled Continentals on my Passion next week. Getting dizzy with size and wheel recommendations as I proceed. Like the looks of the 2015 tire-size setup. Contiprocontact 195/50/R15 on the rear and 165/60/R15 on the front (According to Tire Rack only Continental makes the 165/60?). Those were the standard sizes and brand on the half dozen or so passions I checked at the Smart Center here in Seattle. Anyone satisfied with the performance? Also had recommendations for 175/55/R15s front and rear? Wheel swap in front necessary? One last real basic new Smart Car owner question, are the 2015 and 2009 Passion wheels the same width front and rear? Thanks.
