tire and tube change

[flyguy]

I have 800-6 tires presently and have used Dresser retreads but cannot find them now. Seems 600-6 in all types including retreads are readily available so I am considering getting some new tubes and 600 tires. I've never had to change tubes on an airplane so I have no knowledge about the valve stem type for Taylorcraft wheels. It appears there are at least two types of stem.

Can anyone give me the specification number and/or description of the type stem required.

Re: tire and tube change

You might contact this outfit and see what they have in retreads. I've not dealt with them, but stumbled on the site while looking for source of 8.50-6 tires.

Darryl,

There are some threads about this you can search for. Some get a little off-track but discuss 6 ply as opposed to the original 4 ply and their legality, etc. Also discussions about tubes. Good luck!

Darryl, There are some threads about this you can search for.

Care to share these with us, Marty? I always have problems finding inner tubes with the "correct" extended valve stem, so much so that I leave an after-market valve extender attached.

Re: tire and tube change

As far as my research, you will probably not find the "correct" extended valves, nor did I indicate I knew where to find them. Mine are also short held on with the nut and use an extender for fill-up. General consensus after reading a bunch of threads is Desser for the tubes.

Re: tire and tube change

Thanks Marty. The first thread indicated that a 90 degree stem is what is best. I see aero classic has 600-6 tubes with the 90 degree stem, but they are almost 100 bucks each. I think I might be better off just buying non retread new tires at the high price and stick with 800-6.

OK, edit: Dick, thanks for the link, they list 800 retreads on their site so I will give them an email--see what the prices is. Thanks.

Re: tire and tube change

Just an FYI, I wouldn't install a new tire without also installing a new tube. It is impossible to get a used stretched out tube to go into the smaller space of a new tire without having wrinkles. Over the years I have seen to many tube failures from not replacing them with the tire. You can take this for what it is worth.

I see where you're coming from, and your opinion is always worth listening to.

Perhaps that is where some wheel imbalance I occasionally experience after a touch-and-go comes from: the extra "layers" of inner tube upsetting the balance of the wheel/tyre assembly. A quick tap on the brakes after my touch-and-go solves that.

However, I personally don't agree with your inner tube replacement protocol, if only from a cost perspective. If the tube ain't broke, don't fix it, and personally I've never had a problem with re-using inner tubes when replacing tyres.

Except when I inadvertently pinch the inner tube between the wheel halves, then they are definitely scrap!

Re: tire and tube change

I had a tube failure with 8:00x6 tires on a C-185. Blew out on a pavement landing but the retracted Federal wheel skis saved the day. The mechanic said the tube was previously pinched and was a reused part...possibly stretched but hard to tell. He installed a new tube and tire and made sure the casing was lubed with talc or something that looked like that. He inflated/deflated the tube a few times then set the correct pressure. Cheap fix on an expensive plane that could have ground looped or nosed over.

All I recall is sitting in the cockpit afterwards and looking backwards as I was towed to the hangar with a temp tire.

Re: tire and tube change

I agree with Tom, reusing a tube is a bad move. A couple of months ago I had to retrieve a Bonanza that the owner had just installed new tires with used tubes. The right main went flat, he was 40 miles from home and his cost for me to travel to change the tube was much more than a pair of new tubes would have cost. Late last year I had a similar experience with an old 680 Aero Commander...new tire, old tube.

Re: tire and tube change

Rob, it is not that the old tube is broke, it is the fact that it is no longer the correct size to fit in the new tire. The problems that happen are abrasion of the tube where it folds over, and pinched tubes like you alluded too. I have pinched tubes before I started installing new with the tire, but I have never come close to pinching a new tube.

Re: tire and tube change

And then there are the old tubes that came with the 12D when I bought it. I put new tires on with the tubes several years ago and they have worked just fine, no problems. As I put the new tires on not too long after I got the plane I would guess at somewhere between 10 and 15 years ago. I must have been protected by my exquisite skills at fixing things. Chuckle.

My, my, sitting here contemplating my navel after typing the above I remember that I put the tubes inside the tires and lightly inflated them and then let most of the air out before I assembled the wheel. Guess that must have been good technique or maybe I was just lucky.

Re: tire and tube change

I'm not saying that 100% of the time you will have problems using old tubes in new tires. What I am saying is that if you do have problems it will most likely be the old tubes. Based on my 35 years experience working on airplanes, me personally for the cost of the tubes am not willing to take the risk

[flyguy]

Re: tire and tube change

I'm a lot more worried about things like a tail wire or two coming loose, loosing the horizontal stabilizer, and having the airplane try to pull 20 or thirty negative Gs. Just as an example. I have had some really insane things happen to me in airplanes. Tires are about 125th down on my list of things to worry about when it comes to airplanes.

I do agree that is seems it would be quite easy to damage a tube when installing it, old or new.

Re: tire and tube change

Guys, as a side note to this discussion I know some of us have used valve extensions to be able to fill the tires. I have been using one of these for some of my Harleys, and found out it works great for the T-Craft. Cost is about $11, which for a Harley part is pretty cheap. Part number 42300009 and called a valve stem extension.
