How to Check a Trailer's Tire Pressure

When hitching a trailer to a car or truck, there are several steps you must take before embarking on your journey to the lake, beach or other fun destination. One such step is checking your trailer's tire pressure. It is important to complete this quick step because underinflated tires can lead to reduced gas efficiency and dangerous towing conditions.

Difficulty: Easy

Instructions

1. Inspect the tire treads for signs of wear. If you notice wear and tear on the outside of the tire, this usually means the tire is underinflated. Wear on the middle and inside of the tire may be a result of overinflation. If you notice excessively worn tread on any part of the tires, you may need to purchase new trailer tires.

2. Check the tire pressure. Unscrew the cap that covers the valve through which you inflate the tire. Use a tire pressure gauge (available for purchase at auto parts stores, grocery stores or discount stores) to check the force of the air coming out the valve. There are two types of gauges: manual and digital. Manual gauges have a slider at the bottom. The air from the tire forces the slider to a certain position that indicates how much air pressure the tire exerts. The digital gauges display tire pressure readings on the screen.

3. Look in the trailer's owner manual or on the side of the tire to see how many pounds per square inch (PSI) of air the tires should have in them.

4. Drive to a gas station or car wash, since these locations usually have air for sale (or for free). Inflate your tires, periodically checking with the tire pressure gauge for accuracy. If you accidentally overinflate your tires, pinch the valve to release the excess air.
