Installed them on 15 inch steel wheels on a 2001 Toyota Sienna minivan and they fitted perfectly. At $24 for 4 packs I'm not sure how anyone can complain about that. They fit just like the original factory caps with a steel snap ring and plastic tabs. It's made out of fairly soft plastic, so it took a bit more palm gripping the perimeter of the cleats to install it, but it wasn't any different from the original Toyota covers. We'll see how they hold up, but after a pickup truck hits the freeway at over 65 mph, they hold up well. The appearance of the transporter has also been updated.
