A "test fit" is putting your wheels on the hub of your car to verify proper bolt pattern/hub compatibility and suspension/caliper clearance before a tire is installed. We require all wheels to be test fitted prior to tire installation for a few reasons. In the rare case that your order was picked incorrectly, or boxed incorrectly at the factory, test fitting will mitigate any issues with returns. In the rare case that vehicle year, make, model or submodel was given incorrectly, test fitting would help identify any issues with fitment.
