How to Manually Mount a Small Trailer Tire

Updated February 21, 2017

There are many types of trailers on the road today. We rely on our trailers for our construction jobs, yard cleanup and recreation. Your utility trailer might sit in your yard until you need it for that next job. What a bummer it is to find that your trailer has a bad tire on it right when you need to use it. If you need a new tire mounted on your trailer, you can do it right at home manually. The truth is that many tire stores are not equipped to mount small trailer tires. They normally concentrate on car and pickup tires, and small trailer tire will not fit on automotive tire machines. You will save time and money by mounting it yourself.

Remove the valve core from the tyre's valve stem by placing the valve core remover in the stem and turning it counterclockwise.

Push down on the side walls of the tire, and they will release from the bead areas.

Put the wheel in the vice by turning the handle of the vice to open the jaws. Grip the wheel in the vice jaws and tighten it down. The idea is that the vice will hold the wheel still as you remove the tire from the wheel.

Use your flathead screwdrivers to remove the tire from the wheel one bead at a time. Put the screwdriver in between the tire and the wheel and pry the tire off. You will use one screwdriver and leave it in place and then another screwdriver while working around the wheel until the tire comes off. This process is similar to removing a bicycle tire from the rim.

Place your new tire on the rim and work it on with the screwdrivers in the reverse way that you removed it.

Inflate the tire with the air compressor by placing the inflation hose on the compressor onto the valve stem. Install the valve core with the valve core remover by turning it clockwise.

Check the air pressure with the valve gauge to make sure the psi is correct. The correct psi is indicated on the sidewall of the tire.
