Tail Dolly Tire

On this type of rim, I have had better luck with 4 ply tires. I have a nice 6 ply tire and it's really really stiff, but you just can't practically get it on the rim. It's completely futile. I believe the practical use for that tire is with a split rim such as the glider tail wheel on some models.

What I do know though is just buy the whole tire/hub assembly from monster scooter parts. It's like 10 or 20 bucks,cheap, and works well for a dolly tire.

see this thread and link. 20 bucks.

Nitrogen?

Nitrogen is a larger molecule, thus it only means the, "normal leak rate" is a bit slower.
Nothing else.

Still does not address the original issue, "how do you remove/install" a small tire on a solid rim.

Thanks for trying though......;-)

RTFQ next time though.......... Thanks..........

NNTGBOOS. I am using app that seems not to reply to a earlier comment about foam used in tired. Which I would try nitrogen to see if that held up better than air. Maybe then only a **** of nitrogen once a year would be good.

BTW. YLLAA

The aviation department at Tractor Supply has a nice wheel for $15 which, with some brass bushings to adapt to the axle diameter and space one side of the wheel to the yoke, is a perfect fit in the tail dolly. Believe it's their part number 3553230. Sorry, nowhere near the trailer or a Tractor Supply at the moment.

Having it foam filled fixes the flat and likely the shop installing the
foam will also remove the tube for you and remount the tire. Problem
solved. Good luck with whatever you decide to do.

Yes, but let's fix the flat first... Thanks

I did the foam thing several years ago on my tail dolly after having read someones great advise here on RAS. I regret having done so. It makes the tail dolly a lot heavier. More important, when I'm pushing on unpaved surfaces (which is frequently) it makes the tail bounce a lot worse than it did on air.

This year Schleicher shipped my new glider with a very nice tail dolly equipped with solid rubber tire that is quite soft, a really nice tire. No more flats to deal with or adding air.

Use a good tube and have it filled with helium? Helium does not leak like air.

It leaks faster than air! A LOT faster.

The solid tire from Tractor Supply is what I replaced my tire/tube with. Didn't know if anyone had tried Nitrogen is why I mentioned that earlier.

Nitrogen is slightly lighter than oxygen so, to a first approximation,
should leak out a bit faster than air. However because nitrogen, unlike
air, doesn't degrade rubber, it may be preferable for this reason.

Either air or nitrogen will leak out a lot slower than helium, which
diffuses through solids three times faster than air. Only hydrogen has a
higher gaseous diffusion rate (154% of helium's rate).

However, when you take cost and availability at the airfield into
account, putting air into glider tyres may turn out to be the better
inflation method.

Went to a hardware store solid tire on the tail dolly and Amazon solid tire on the wing wheel years ago. Tired of fixing flats. Yes, they're heavier (a good thing on the wing wheel). They bounce more. But hassle free. Life is short.

Solid tire on the trailer dolly wheel also. Now all I need is run-flat tires for the trailer and a solid tire for the glider main wheel and I'm done.

Oops, there's the glider tail wheel. And the van....
