Will Car Magnets stay on a car door doing up to 75mph?

Yes. Our heavy-duty car magnets are designed to stay put at highway speeds, including up to 75 mph.

• The 30mil heavy-duty material grips firmly for driving.
• Apply to a clean, dry, magnet-receptive steel surface for the best hold.
• Rounded corners help resist wind lift at speed.
• Check the magnet occasionally on long trips and reseat it if needed.
