How To Change A Boat Trailer Tire

Be safe while you correctly change your boat trailer tire

Although similar to changing a car tire, changing your boat trailer tire is different.  The Boat Owners Association of the United States wants to ensure that if need to change your boat trailer tire you do it safely and correctly. Here’s a quick how-to to get you back on the road, so you can get back to the water.


The safe and correct way to change your boat trailer tire:

Pull completely off the road onto a level surface. Be sure to use your hazard lights and engage the parking brake of your vehicle. This lets other drivers know you are doing maintenance to your trailer and ensures the vehicle stays motionless. If you have them, place hazard cones or flares in the appropriate area before beginning repairs.


Check to ensure you have enough clearance between the frame and road with the jack. You need enough room to remove the flat tire and replace it with a new, inflated tire. If required, you may need to improvise with a block of wood under the jack or tire to obtain the desired height.


Insert the jack under the frame or axle as close as possible to the flat tire; selecting a solid location is important – you wouldn’t want the jack to slip! But wait, don’t start jacking yet. Loosen the lug nuts while the tire is still on the ground; this prevents the wheel from turning. It is important that you do not use lubricant or anti-seize on your lug bolts – for obvious reasons, it’s your tire!


Okay, now jack it up, remove the lugs and replace the old tire with the new inflated spare tire – if you need to you can jack it up a bit more to fit the new tire in place. Tighten the lug nuts by hand and secure them with a lug wrench. Then give the tire a quick spin to ensure nothing is hung up.


Slowly release the jack letting the tire touch the ground. This will also make the final tightening easy. After driving for a bit you should retighten the lug nuts.

The leading cause of trailer tire failure is tire under inflation; check your tire pressure often and drive safe.
