If you live and work in a snow-heavy town, chances are you know just how invaluable a good snowblower can be. Whether you’re blasting snow off your driveway, clearing sidewalks, or just trying to cut a walking path around your property, snowblowers make short work of even the deepest powder. Unfortunately, most snowblowers spend the offseason sitting in garages, hanging out under carports, or just sitting outside under a tarp, patiently waiting for winter to roll back around. These are the ideal conditions for rubber to deteriorate and for leaks to form, which means more often than we’d like, our first snow of the season finds our snowblowers sitting on at least one flat tire. We’re here to tell you not to sweat it. This guide will show you how to fix a flat tire on a snowblower in under five minutes to get you back up and running.

How To Fix A Flat Tire On A Snowblower: Step By Step Instructions

When most snowblower owners imagine getting a flat tire, their first thought is all the painstaking work that lies ahead to get their blower back up and running: Pulling the wheel off the axle, 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 short order using simple tools you’ve already got laying around.

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 snowblower forward or backward a few inches until the valve stem of your tire is sitting around the 6 o’clock position, as seen above. Next, grab a few boards, a brick, or something similar to wedge under the body of the blower to get the tire up in the air.

If your tire has come completely off the rim, don’t sweat it. Once it’s in the air, simply wrap a tie-down strap or a length of rope around the center of the tire and tighten it down until the bead is sitting back on the edge of the rim. Add a little air to the tire to get it to seat again, remove the strap or rope, then proceed to step two.

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 basic 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 snowblower 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 snowblower 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 snowblower tire:

Step 5: Reinstall The Valve Core

Once you’ve got the proper amount of sealant in the tire of your snowblower, 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. Give the tire a few hearty spins around once it’s back up to pressure.

Step 7: Go Blow Some Snow. You’re All Done.

Believe it or not, that’s all there is to learning how to fix a flat tire on a snowblower: You’re done. The only thing left to do is get blowing. That’s because the rotation of your snowblower’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 protects your snowblower from future flat tires for up to two years or more.
