Is there any greater joy than upgrading from a tired old push mower to a proper riding mower? No more sweating and grunting, no more rocks and sticks flying into your ankles, no more taking all afternoon to cut the grass. Your biggest concern now is what sort of ice-cold beverage to put in your cup holder. Well, that, and flat tires. Unfortunately, riding mowers get flat tires way more often than they should for one reason or another, but getting a flat on your mower doesn’t have to ruin your day. We’re here to tell you how to fix a flat tire on a riding mower the quickest and easiest way possible.
How To Fix A Flat Tire On A Riding Mower: Step By Step Instructions
When most riding mower owners imagine getting a flat tire, their first thought is all the painstaking work that lies ahead to get their mower back up and running: Jacking the mower up off the ground, unbolting the wheel, breaking out the rasp, the tire plugs, the rubber cement… We’re here to tell you to skip all that. There’s a better way. Here’s how to fix your tire in five minutes flat with next to no tools whatsoever.
Step 1: Prep The Tire
Leave the jack on the shelf, the wrenches in the tool box, and the innertubes in the box: You won’t be needing those. To prep your flat tire, simply roll your riding mower forward or backward a few inches until the valve stem of your tire is sitting around the 6 o’clock position, as seen above. If you can’t get your mower to roll by hand, don’t be afraid to start it up and drive it forward to get the stem where you want it: Riding a few inches on a flat tire isn’t going to hurt anything.
Step 2: Deflate The Tire And Remove The Valve Core
Next, you’ll need to get any remaining air out of the tire. To do this, simply remove the top cap from your valve stem, and depress the button on the top of the schrader valve using a fingernail, a key, a screwdriver, or whatever else you’ve got on hand. Once you stop hearing air escape from the valve, you’re ready to remove the valve core.
The easiest way to do this is with a valve core removal tool, but if you don’t have one handy, don’t fret. A good set of needle-nose pliers can be used to remove and reinstall a valve core in a pinch. (If you don’t own a valve core removal tool, we will say that it’s a great little tool to keep on hand, and we’ve got a great one in our store that also happens to hold replacement valve cores. Check it out here.) Turn the valve core back counterclockwise until you’re able to remove it from the valve stem and then set it aside.
Step 3: Prep Your Tire Sealant
Our tire sealant is the special sauce that makes repairing a flat tire on a riding mower so quick and easy. Our special formula uses up to 50% less sealant per tire than the competition, so you’ll only need a single 16-oz bottle to repair even the largest riding mower tires out there.
To prepare your sealant, turn the bottle upside down and shake it up for several seconds to get it properly mixed.
Optional: Attach Sealant Applicator
Technically this step is completely optional, as our sealant can be poured straight from the bottle thanks to our tapered end cap, but many users find attaching our threaded sealant applicator hose directly to the valve stem makes it easier to keep sealant from ending up on the garage floor. Completely up to you, but if you want to simplify the process even further, you can pick up an applicator in our store along with your sealant when you go to check out.
Step 4: Pour In Sealant
Now that your sealant is shaken up and ready to go, all you have to do is pour the recommended amount directly into your valve stem. You’ll find a handy measuring guide down the side of the bottle to take the guesswork out of measuring, as well as a handy sealant calculator on our website you can plug your tire dimensions into to find the right amount of sealant. It should look something like this for a standard riding mower rear tire:
Step 5: Reinstall The Valve Core
Once you’ve got the proper amount of sealant in the tire of your riding mower, it’s time to reinstall the valve core. To do this, simply grab your valve core tool of choice and turn the core clockwise back into the valve stem until it’s fully seated.
Step 6: Reinflate Your Tire To Its Normal Pressure
Now that your valve core is back in place, you’re able to reinflate the tire to your normal running pressure. We generally recommend using an air compressor to save time if you’ve got one handy, but a hand pump works just fine in a pinch.
Step 7: Go Cut Your Grass. You’re All Done.
Believe it or not, that’s all there is to learning how to fix a flat tire on a riding mower: You’re done. The only thing left to do is get cutting. That’s because the rotation of your riding mower’s tire is all Stans Sealant needs to get to work. As the tire rolls, the sealant you’ve just put inside works its way around, fully coating the inside surfaces of your tire.
This will not only completely seal your current flat, but it also keeps your riding mower protected from future flat tires for up to two years or more.
