Hubcaps really are the best way to instantly improve the appearance of your vehicle. Taking off the old, scratched, out-of-style plastic caps feels good, but many drivers have never changed their wheel covers before. No worries, making sure you are ordering the right size is very easy.
All hubcaps are listed by their diameter. All you need to do is check your tire! The diameter is indicated with an "R"-prefix, and will read as "R16" - indicating you have a 16 inch rim diameter.
The Image below shows the full display as it is etched onto all tires. It indicates a 15" diameter.
