Rex’s comment about the green slim sealant reminded me of this one.  

   

A local A&P puts tires on with epoxy glue to glue the tires to the rim.  You can run low air pressure in the tires with little worry about them slipping on the rim and cutting off the valve stem on the inner tube.  

   

It sounded strange to me at first, but it does make sense.  The epoxy works great in shear strength, but with little tensile strength to the rubber, the tires easily come off when you want them too.

 Subject: Buffed down tyres  

  

     

Rex,

 I have an extra set of tires that are the smooth buffed atv tires.  I was planing

 on using them on my classic 4 when my lawn tractor tires wear out.  What was

 "shocking" about yours?

Tom,  

    

         the buffed down tyres were only two ply and they only had to see a grass field and they went flat.  My Lawn tractor tyres are 4 ply. I couldn't find tubes for the buffed down tyres and that didn't help. I have 8" steel rims with brake disk lugs welded on the back. This causes slight distortion on the inside and leads to poor sealing without tubes. The buffed down tyres were squirmy at 9-10 lb pressure at times but too tight at higher pressure. I think my slightly smaller Lawn tyres handle excellent at 18 PSI. I used green slime sealant in the buffed down tyres only to find it started attacking the rims. All in all I don't want to see them again. I couldn't put them in the bin fast enough.  

    

                                                                                                                                                                                                                                              Rex.

Maybe I'm lucky or just stupid, but I'm running without tubes in my  

tires. I have the early Douglas one-piece (welded aluminum) rims, with  

Cheng Shin tires, and they are a beast to install or remove. I have one  

tire that loses about 4 pounds pressure in about a month's time, so I  

keep an eye on that, otherwise no problems so far. I do mostly grass  

runways, but if I go to a paved airport, I don't worry about it. I'd  

say it's probably a 60-40% mix of the two. Probably my 3-point landings  

keeps me slow enough to avoid the dreaded rim slipping.

Does the green slime affect aluminum rims or just  steel.

Two of here in the Austin, Texas area are using the exact same tire as Lynn. 

We have about 600 hours between the two of us and have never had a probem. 

lMost of our flying is on paved runways.  We use 14 lbs prssure.

I've been reading the mail on this one for a day or so now.  I find it a bit

amazing that you guys are getting tire slippage on the rim.  There are only

two ways that I can see of getting  slippage; 1. the rims are extremely

heavy and when you touch down that causes the tires to slip on the rims.

Rims that heavy would be too heavy to fly.  That brings me to the second

reason 2. There must be some pretty heavy braking going on.  Especially with

low pressures on soft surfaces.



One of these days I'll try those funny round things, currently stored in the

back of my shop, on my plane.  In the meantime do not archive the fact I

like floats!

Are you using tubes, Jimmie?

I also run with no tubes. The tire shop puts a black goo on. No problems in 

550 hours.

I have 660+ hours on my KFIV, all with Chen Seng  buffed tires, no tubes and no slippage.  90% of landings are on  pavement.

  

 This is my 4th set of tires and after the first  change; I started going to a local ATV shop to have the tires changed (he can  also balance them, but I've not done it yet - will try for the next set).   Its a bargain not to have the hassle or worry about a tire shop bending the rims  - which happened the one time I went to a tire shop.

Way back when... I had problems with the tires slipping on the rims.  We always ran very low air pressure (very rough field).  Our fix was to drill six equally spaced holes in the bead of the rim (both sides).  Then we carefully screwed in a #6X3/8 stainless sheet metal screw.  They were never long enough to go all the way through the bead of the tire, but provided enough grip to STOP the tire from slipping on the rim.

Aha! Shades of early drag racing....I used to do the same thing with 

slicks on my dragster and low tire pressures.

Lynn,

Actually that's were I picked it up at years ago.  Baby powder can be used between the tire and the tube.  It acts as a lubericant between the tire and the tube (they don't stick together)  This can help with slipping tires.  I use baby powder on all applications that have tubes.
