I have this wheelbarrow with tubeless tire, I had to replace it with the new one, however I don't see how to pump it! The tire is quite stiff, and it was tricky to put it on the rim, but now it looks like the tire isn't well adjusted to the rim. Did I do something wrong? How do people normally pump this type of tires?
Looks like the typical gap one gets when mounting a tubeless tire. You'll need to get the bead to seat against the rim as you pump air (hopefully quickly) into the tire - a hand pump might not do it.
Sometimes you can jiggle the tire to effect a temporary seal around the bead as your compressor dumps air in. Using a clip-on tire chuck will help.
Some folks "squeeze" the tire with a strap around the tread area. I've seen a device called a bead expander, and this guy shows the use of some large tie-wraps to achieve the same thing.
If you're not afraid of a little fire then this could work:
- Put on some safety glasses, preferably tinted
- Put on some rubber gloves
- Put on some ear protection
- Have a water hose ready
- Spray some highly flammable aerosol into the rim of the tire such as carb & choke cleaner or WD-40 per the video
- Place aerosol can at least 20 feet away from the tire
- Remove your rubber gloves just in case they have any aerosol on them; melting rubber on your skin is not a pleasant feeling
- Cover your eyebrows with a damp bandana or damp towel or something
- Get some fire near the tire
- Try closing your eyes or turning your face away from the tire right before ignition
- I would advise against using your aerosol can as a flame-thrower but it does add a certain coolness factor
- You can just toss a lit match in the general vicinity of the tire (try not to land the match inside the tire or else you'll get rattling noises when using the wheelbarrow)
- You can light a stick or newspaper on fire and bring it close to the tire
- You can fire up a propane torch if you feel comfortable
- The aerosol remnants should immediately ignite drawing a vast amount of air directly into the tire; this is where that safety equipment comes in handy
- If you chose the match ignition method or any other "toss a burning object at the tire" method then exercise extra caution because the tire's rapid expansion could send the burning object flying right back at you
- You may need to squeeze the tire around a bit to introduce more air to the fire to achieve the desired woosh of air. You should do this by beating the tire with a long stick to avoid personal damage in the event of a tire explosion.
- If this doesn't work then spray with water, let it dry, and go back to step #5
- Once the tire seats itself then the fire will suffocate inside the tire
- If the outside of the tire or rim is on fire then spray it with some water; you may wish to spray with water even if it is not burning
- Inflate the tire to proper pressure
Take it to the local tire store, and ask them to inflate it - they'll use their bead-blaster machine to mount it. Should be little to no cost.
The next time it happens, ask the tire store to put an innertube in the tire. That solves the problem forever. (Only do it the 'next time', because it may never happen again..)
I've had decent luck using a couple of plastic bags and even saran wrap. I rolled them up and placed them near the rim so that it fills in the gap enough to get a better seal. The pump then works well enough to expand the tire.
The gap shown in the photo is small enough for this trick to work.
Long term solution is to have it filled with foam.
The people who recommend a strap around the perimeter of the tire are correct, and such straps, often inflatable, are made for that purpose. However, a couple of times in a pinch, I have removed the belt I was wearing and wrapped it around the tire and pulled it in as tightly as I could. This has actually worked for me. You should probably remov the valve stem to let the air in faster and thus with more force.
I've likewise used my belt. Put the belt around the tread of the tire, squeeze the tread inward to get the bead to push out and set against the rim. Then inflate the tire.
I've had to do it several times over many years, with the same tire. The tire holds air just fine, for months, even under weight. But after going un-used for several seasons it eventually leaks out, enough to loosen the bead and lose the rest.
A strap with a come-along ratchet is easier, but a regular waist belt works in a pinch.
If the tire went flat it has a leak. Just reinflating the tire will not fix the problem. The most likely causes are a tire puncture, or a bead leak from either degraded rubber on the tire or rust on the wheel (not likely in your case with a plastic wheel). The easiest solution is to remove the wheel, the tire and the Schrader valve. Purchase an inner tube of the correct size. Most big box stores carry them. If you have trouble finding the correct size for a wheelbarrow look for a tube designed for a snow blower or lawnmower.
