Prevent Flat Spots
Make sure your tires are inflated to the recommended tire pressure. If a vehicle is left stationary for too long, the tires could develop flat spots
as the weight of the vehicle presses down on the tires' footprints. This process occurs at a faster rate in colder temperatures and with vehicles equipped with performance tires or low-profile tires.
In some cases, simply having someone drive the car for a while will bring the tires up to their normal operating temperature and get rid of any flat spots. In more severe cases, a flat spot can become a permanent part of the tire and it will need to be replaced.
If your car will be in storage for more than 30 days, consider taking the wheels off and placing the car on jack stands at all four corners. This step requires more work, but it can save you from needing a new set of tires. Your tires will be in much better shape when you return if they haven't had the weight of the vehicle resting on them for a month or more.
