How to Refill Riding Lawn Mower Tire That Fell Off Rim


A common problem with riding law mowers is flat tires.  The PSI in lawn mower tires is actually pretty low, just around 15 PSI on average.

Also when you get a flat, it's common for the tire to come off the rim.  So when you try to fill it up with air, it just leaks out the side and the tire doesn't fill up.

The fix is to try and apply even outward pressure and seal the bead between the tire and the rim.  That can be done with a ratchet strap or a rope and pipe.

First, jack up the mower.  Second wrap the rope around the tire, then the pipe.  Then continue wrapping around a second time.

You will then twist the pipe, which will tighten the rope.  This will push the middle of the tire in and the edge of the tire out.

Do this all at the same time and then try adding air to the tire.  Hopefully you get a good seal with the tire bead and it will inflate.

It takes a lot of force.  Also this is common when you get a brand new tire.  In my case it was with an old worn out tire that got a flat.
