To reduce dry rot all vehicles must be driven monthly. This will help reduce dry rot and aid in preventing flat spots from developing on tires.

Dry rot in tires is caused by intense exposure to sunlight (Florida). It often occurs when automobiles are not moved for long periods of time sense part of the tire is constantly exposed. Rot however may occur in vehicles that are used daily. When trying to determine when it is time for new tires, looks at how much tread remains, also check for signs of dry rot.

The most common sign of dry rot is cracking around the sides walls of the tire. If this appears tires must be change immediately.

Dry rot can also cause splitting between the treads. Tiny cracks between the treads may not be a sign of dry rot. It could be signs of normal wear and tear. Small imperfections may not be a risk, however if there is significant cracking the tires need to be replaced.

Browning or yellowing of the tire is sign of advanced dry rot. These tires are not safe and must be replaced. Do not attempt to drive on discolored tires.
