I have a 2011 Infiniti EX35 with only 13,000 miles on it. I really want to exchange the 19 inch wheels and tires on this car for the 17 inchers that they used prior to 2011 but cannot find any cost effective way to do it. Can't find any place willing to do any type of trade-in even on just the wheels. Since cost is definitely a huge factor here (we just bought my wife a new car as well), if money is an issue, should I wait till the tires are worn out and then try to sell or exchange the wheels? All thoughts and input will be highly appreciated. The reason I want to do this is that based on the test drive of a 2010 with 17 inch wheels, the ride was a lot better and the noise from the tires was a lot less with the smaller tires. However, the only Infiniti EX we could find in Kansas City that had decent mileage and a good price was a 2011 with the 19" wheels.
