You can dial in year, make and model of car (including Rancheros!), and display different wheels on that vehicle: http://app.ridestyler.net/5E124B94BF264A99BEEA7D0307C53D85?mode=webbot
Thanks. This is the best wheel simulator I have seen. Very true graphics. I put 15s on my Ranchero years ago. When I selected my year (78), it only showed 14" wheels, but later in the process it allowed selection of 14" or 15"!
