I want some opinions on this. I read once that when storing a trailer (with a boat on it) for a long period of time to put the trailer on jack stands or similar to take the weight off the tires. The theory is the tires would become slightly deformed ( out of round) from sitting in the same postion for extended periods of time. Causing the tires to wear out or blow out prematurely. I live in Minnesota and the boat is stored about 5 months a year. A couple of extra minutes to jack up the trailer before putting it away sounds better than a blow out or replacing tires. <br /><br />I have an 18 ft boat that weighs about 2500 pounds an sits on a single axle trailer.
