Scion tC Tire Size Guide by Model Year and Trim | Rim Dimensions

The Scion tC features varying tire sizes and rim dimensions depending on model year and trim level. Standard tire markings typically include width, aspect ratio, and diameter, such as 215/45R18 for certain trims. Rim widths commonly range between 7 to 7.5 inches with diameters from 16 to 18 inches.\n\nEarly model years (2005–2010) often came equipped with 16-inch rims, while later versions and sportier trims upgraded to 18-inch rims for enhanced handling and appearance. Tire size differences can affect ride quality and performance, so it’s essential to reference specific trim details.\n\nWhen comparing trims, pay close attention to rim width × diameter metrics alongside tire sidewall dimensions. This helps ensure compatibility and optimal vehicle dynamics. Always consult the owner's manual or manufacturer specifications before making tire or wheel upgrades.
