Do Lawn Mower Tires Have An Inner Tube?

If you’re not familiar with the purpose of inner tubes in tires, you may not be familiar with the anatomy of pneumatic tires. Some of them have inflatable rings inside for structural support. The rings also provide suspension, and they fit tightly inside the tire’s casing. 

Not all tires have inner tubes, though. It depends on their type and the vehicle. For example, bicycles have inner tubes, while not all cars do. So do lawn mower tires have an inner tube?

No, most lawnmower tires don’t have an inner tube. Here’s everything you need to know about the matter.

Do Lawn Mower Tires Have An Inner Tube?

Most lawnmower tires don’t have inner tubes, and they don’t need them to run. The rims mostly have a conventional design, where they’re made of one piece. Because of that, they don’t need an inner tube because they already don’t leak air.

Generally, tires without inner tubes have multiple benefits. For one, they don’t leak air quickly when the tire gets punctured, so you have some time to deal with the issue before the tire flattens out on you. 

Additionally, these tires offer better heat emission and don’t need a lot of maintenance.

How to Know If My Lawn Mower Tires Are Tubeless

Most tires will have something on them that tells you if they’re tubeless. Some tires have ‘Tubeless’ written on their sidewalls, along with other info and measurements of the tire. In this case, the easiest way to know if your tires have tubes is to check if there’s anything written on their walls.

You can also look at the valve. If it’s falling inside the hole, there’s a chance your tire has tubes inside. As a last resort, you can move the tire’s bead around. You may be able to see if there’s a tube inside the tire or not. It should be listed with the mower’s specifications, anyway.

What Are the Advantages of Inner Tubes in Lawn Mowers Tires?

Inner tubes in tires are good because they allow the tire to take a lot of abuse without wearing out. In addition, they increase the tire’s longevity because they offer protection. 

On top of that, they protect the tire when the rim is damaged. So the rubber doesn’t get ruined on impact.

If your tire’s rim gets damaged and your tire is tubeless, the rim may break through the seal. If your tires have inner tubes, that won’t happen.

There’s also the fact that when something goes wrong, you can replace the inner tubes alone without replacing the whole tire. But, of course, that means fewer costs for you.

What Are the Advantages of Tubeless Lawn Mower Tires?

Since most lawn mower tires are tubeless, you may start wondering what that means for you and how you can benefit from it.

For starters, tubeless tires have heavier rubber on the outside, which is harder to puncture or breakthrough. At the same time, if the tire gets punctured for one reason or another, the air will leak slowly, allowing you to drive the mower or move it for some bit before the tire completely flattens. Needless to say, that means more safety for the rider.

Regular tires with inner tubes may cause a mild exploding effect when they’re punctured because of the depressurization. They’re also significantly heavier than tubeless tires because they carry the extra weight of the tubes.

Moreover, these tires offer better heat emission because they don’t have liners like other tires do. That means that when the heat forms inside the tire, it’ll emit from the metal rim, completely dissipating and keeping the tire safe.

Lastly, when you need to replace your whole tires, tubeless ones are more affordable to replace because of their structure.

Frequently Asked Questions

If you still can’t grasp tubeless tires and their benefits, here are a couple of answers to frequently asked questions that may help.

Can the tubeless tires on my lawnmower flatten?

Tubeless tires rarely flatten; the worst that can happen is that they’ll diffuse some of their air, and a puncture will be obvious. 

However, they won’t flatten completely because they have a sealant liner on the inside that’ll close the small punctures or hold them off until you fix the issue.

Still, tubeless tires may flatten, but it’s a rare occurrence and only happens if the sharp object creates a large hole.

How durable are tubeless tires?

Tubeless tires are pretty durable because of their safe structure. However, their longevity of life depends on the surrounding conditions. For example, drier weather conditions may decrease life expectancy because the air in the tires will evaporate faster.

The same goes if you manage to puncture one of the tires and fix it. It’ll typically have a shorter lifespan than a tire that has never been punctured. Tires with tubes are sometimes considered more durable because you can fix them by replacing the tube only.

How to Fix a Punctured Tubeless Tire on a Lawn Mower?

Since most lawn mowers have tubeless tires, yours is probably the same. So, how will you fix it when something goes wrong? Follow these steps.

Step 1: Find the Puncture

The first thing you should do is raise the mower off the ground, so you can reach the tire easily. Put your jack under the mower’s body, and start pulling its lever repeatedly to raise the mower. Whenever you can, try to align it with the mower’s frame rail.

When the mower is two or three inches off the ground, stop lifting it and proceed.

Now, start rotating the wheel to find the puncture or its source. You’ll likely find a sharp object lodged inside.

Step 2: Take the Sharp Object Out

When you locate the puncture, start inflating the tire using your air compressor, then remove the object lodged inside. If it’s too small to take out using your hands, you can use a pair of pliers. Just make sure you don’t close the teeth on the tire’s rubber. 

After removing the sharp object, get a hole reamer and insert it in the punctured hole on the rubber surface. It’ll smoothen the hole’s edges so that you can insert the plug easily.

Step 3: Insert the Tire Plug

Now, grab your plug insertion tool from the repair kit, and attach a plug to it. Apply a coat of rubber cement to the plug, then press it into the hole with gentle force. The rubber cement isn’t necessary, but it’ll help the hole seal faster.

Only insert the plug about three quarts in, then pull the insertion tool out. You’ll want to pull it out forcefully and sharply, so it lets the plug settle inside.

If the plug isn’t even with the tire, you can cut some off its top using a razor knife or any sharp object. Leave your tire for around 10 minutes, so the rubber cement has some time to seal the puncture. 

Lastly, re-fill the tire to return it to its appropriate pressure, and it’s ready to use again.

Conclusion

Most lawn mowers don’t have inner tubes, but it depends on your model and when it was manufactured. Generally, tubeless tires have multiple benefits. They’re durable, safe, and more affordable to replace. 

However, if you want the benefits of an inner tube in your tire, you can always insert tubes in your tires if you wish.
