Steering wheels have generally gotten smaller over the years due to improvements in power steering technology.
A steering wheel cover is a great way to protect your steering wheel from wear and maintain its resale value. An improper fitting cover is a safety hazard because it could slide around while trying to manuever the vehicle.
MyBestVehicle.com is a website designed to quickly find data and specs on your particular vehicle.
Consult with the vehicle's owner's manual to confirm the steering wheel size in your car.
A measuring tape can also be used to measure across your steering wheel to get its diameter. A flexible sewing tape can be used to get the grip circumference.
After installing a steering wheel cover be sure to thoroughly test it while the vehicle is parked to ensure it does not slide around the wheel.
