The Boat Trailering Guys
My boat sits on the trailer for months at a time. A buddy who was visiting says I run the chance of having what he called "flat spots" on the trailer tires as a result. What are flat spots and is this something I should be worried about?

GEORGE: These occur on your car's tires too if you let it sit for a long period of time. Not to worry, because after a mile or so of driving the "flat spot" will go away. MIKE: Flat spots occur when the tires sit in the same position for a long period of time. It is more prevalent in Bias Ply tires. They will usually go away when it warms up and tire is used frequently again, although you may experience "thumping" for a period of time. There may be permanent damage depending on the overall condition of the tire. It is recommended that you block your trailer in a manner that takes the weight off of the tires during long-term storage (2+ months). It is even better if you can take the tires off and store them in your garage or basement. Tires are susceptible to degradation from UV rays so it is best to cover them or store them inside. It is also recommended to lower the air pressure.
