The Lowdown On Tires

They're the most important part of your boat trailer.

Tire Wear

Watch for spider cracks that occur from dry rot and uneven tread. If the tire wears in the center, it indicates overinflation, if it wears on the sides, it indicates underinflation.

Many trailer tires have treadwear indicators that will show a different color as the tread becomes worn. Look for the last four digits of the DOT identification stamp on the sidewall of your tire. The first two numbers represent the week in which the tire was made. The second two represent the year. A tire with a DOT code of 1209 was made in the 12th week of 2009 (on some tire brands, this may be on the inside sidewall).
