Flat tyres

[rhtrudder]

Thoughts on using anti puncture goo in aircraft tyres, planning on some trips away , don’t need flats, anyone tried this 

[turboplanner]

There's a long and informative thread about this on the site.

[skippydiesel]

There was a conversation/thread on this, just a little while back. From imperfect memory the respondents fell into three camps;

1. Carry a spare inner tube
2. And or tube repair kit
3. Various goo supporters

The first two are self explanatory. The third:

• Some opinion that goo's of various types, including the pressurised (inflating) delivery, are not suitable for tubed tyres.
• For the most part direct the user to drive for ?? kilometers at significant (?) speed - presumably to distribute the product & through tyre heating, cure it. Not so easy in an aircraft.
• May cause a severe imbalance - Could be dangerous, would certainly be alarming.
• May get you off the ground, only to arrive & land with a flat tyre - not a "good look" at all.

 

I am a supporter of 1 & 2  Carry a spare tube & tyre repair kit. However I recently experienced multiple small holes ,in one of my Ranger tubeless tyres, and for the first time used a pressurised goo type sealer - worked a treat. Did have to pump up to to correct pressure and complied with driving instructions, by doing a  20 kilometre round trip at 100 kph - not so skeptical now

 

Possibly your best preparation/defence against punctures, is to have your tyres inflated to their highest recommended pressure, to reduce side wall bellow/flex. The side walls are the thinnest part of the tyre carcass and most prone to damage. Low pressure allows the side walls to flex out more than normal, making them more vulnerable to penetration. 😈

I am set up to fix flat tyres when flying solo; so have a jack (0.5kg by Peter Anson Engineering), two bottles of repair foam for tubed tyres (0.3kg each), two tubes, tube repair kit, spare valves and removal tool and the necessary tools to remove wheel and disassemble the wheel; and a pump.  Mine is split rims and easy to get apart.  I've been involved with Savannah tyre changes and re tubing and there are a problem to get tyre bead off the rim, real hard and near impossible.  I say be able to do solo as you need to get wheel off the ground and a rock under the leg if you don't have a jack or a support. The P3 is great for a quick fix, get you going and about $26 a can.

Just curious - does the P3 have a flammable propellant and the can have a temperature limit stated on it at all ?

[skippydiesel]

Blueadventures,

 

As a repair in a can proponent, would you mind addressing the perceived negatives.

 

How often have you used this sort of product onan aircraft tyre?😈

It contains a flammable propellant; there is a safety data sheet for it. It works very well I'm told by a reliable person who has used two cans on at least two occasions as he fly's a Nynja at an airfield that has thorns in the grass.

I have detailed my knowledge of the P3 product in the earlier post and in the other thread.

 

It would be helpful to all if you could update your post with the product brand detail of what you used.  You have omitted this information.

[skippydiesel]

Further to Blue adventures request - some information about the wheels/tyres that this or similar products have been used on.

 

Reasons -

As stated earlier here is some suggestion that its not so effective in tubed tyres.

How has the instruction post application,  to drive for a certain time & speed, been accomodated? 😈

[facthunter]

It was introduced way back when tubed tires were common  Fenelec I think.  Nev

 Personally I'd prefer tubeless tires as you don't tear the Valve out if the tire rotates a bit on the rim. That gives you INSTANT deflation. Caltrop is the worst thing  for Punctures. Echuca had it. and It's hard to eliminate once you have it.  Nev

Yes , you wrote about the product, all the tools you have and some tips on wheel/tyre removal  but did not mention any actual experince of the product mentioned/shown.

 

Experience is all important. Without it you are just echoing marketing & third hand myths, which does little to inform the Forum readers😈

Skip; I've shared what I know, Your detail is piss poor as you don't bother to share the brand you used with success.  You often do this when you push for detail off myself and others, you need to lift your game or exit.

 

As for your comments running down my information you can keep your opinion to yourself.  For others I can assure them that the information is as good as top shelf RD testing by an approved authority, and I'll back in the effectiveness of the Motul P3 product for flat tubed tyres.  

[skippydiesel]

So Blue - I take it from your "forceful" response - no experince.

 

I am NOT "running down" your information. I am rightly seeking first hand experince.

 

"You often do this when you push for detail off myself and others"

 

I think you will find that I ALWAYS give as full an account of my experince as I can - Am upfront when speculating or passing on others comment/information, that I don't have personal experince of.

 

 As my experince was not directly related to aviation, I did not think to include the brand.- it came from Repco - cant remember for sure - think it may have been the Holts product (pictured). The bloke behind the counter reckoned it was a good one.

 

I stress - I used this on a 4x4 tyre - not an aircraft. The multiple  holes were very small, deflation rate estimated on 5psi/day - no idea what caused the problem.

I also stress - being a land based vehicle, I was able to follow the, after use, instructions, to drive for a distance (?) at, I think, at 60 mph  - this is likly not practical in an aircraft. I also had to supplement the pressure delivered by the can, with added inflation to correct psi.

well ! .

I have bought at least a half-dozen products.  but never used one . 

When 4x4ing I found it was quick to use " tyres-pliers  " & put a proper patch inside the tyre I . should give / throw them out . ( dead weight ).

Problem (for me) is they are such a great idea BUT who do you know has had success, using any one  of the several products, on/in an aircraft tubed tyre?😈

[BurnieM]

Do we need to analyse this to death ?

'Repair in a can' products are cheap and in some circumstances (mainly with tubeless tyres) useful.

They are less useful with tubed tyres where the tube sometimes tears.

 

'Repair in a can', spare tube, tools to remove the wheel and the tyre from the wheel and a pump are still cheap and relatively light weight.

Buy it, chuck it in the back and hope to never use it.

RR, I notice you use the words "Anti Puncture" as oppossed to puncture repair.

Are you referring perhaps to products like Slime?. I have experience of Slime and other similar products in Mountain Bike tyres and they are effective on small punctures but they dont half leave a mess inside the tube or tubeless tyre.

I would steer clear of these products.

Are your Aircraft tyres tubed or tubeless?

 

If tubeless and you were actually asking about repair and not prevention, then the motorcycle Plug type repair kits work really well in my experience.

[skippydiesel]

BernieM,

"Do we need to analyse this to death ?"

 

Yes!  Why - as is often pointed out, we are discussing this product/concept application in aircraft tyres - not ground based vehicles.  If the use of these product do end in a "death" that could have been prevented by some informed comment, we are all moral responsible.

 

It would be realy great if someone  WITH EXPERIENCE addressed some/all of the following:

 

• Some opinion that goo's of various types, including the pressurised (inflating) delivery, are not suitable for tubed tyres.
• For the most part direct the user to drive for ?? kilometers at significant (?) speed - presumably to distribute the product & through tyre heating, cure it. Not so easy in an aircraft.
• May cause a severe imbalance - Could be dangerous, would certainly be alarming.
• May get you off the ground, only to arrive & land with a flat tyre - not a "good look" at all.

Good points Red,

I too have seen Slime promoted as an "Anti puncture" product to add to lawn tractor/mower tyres when new. Of course its not "anti puncture" but can block small leak that would otherwise cause the tyre to deflate. I speculate that its use may cause a  significant out of balance condition, which has no significance for a mower but could be quite dramatic in an aircraft .

 

"...Aircraft tyres tubed or tubeless?"

In my, limited, experince most small aircraft tyres are tubed

 

Tyre plugs work very well  in all classes of ground based tubeless tyres. I would guess that they would be a worthwhile item to carry in a small aircraft fitted with such tyres. 😈
