Ghetto tires on UST rim Carpet tape?

[T-rex]

Not sure if anyone has tried this so any heads up is good. Some people use a carpet glue to seal to BMX size 20 tube cut open to the tire to insure no burping. Can be seen here http://www.youtube.com/watch?v=IQX3C...eature=related

I`ve also been told that electrical tape is also good to help seal the tire to the rim when going tubless and also sealing the rim @ spokes so no need for a bmx tube just the tubless stems.

I was looking for some electrical tape and found some Double-sided carpet tape I had left over and think this might be the best for using the non bmx tube setup.

Anyone ever tried this? it is sticky, super gummy & about 3 times thicker than electrical tape.

The fact that it is double side means dirt and small rocks could stick to it I`m just not sure how long it would take before the sticky gets dulled out. Maybe after the tire seals use some Baby powder to cover the sticky stuff still showing ???

Looking forward to feed back, sorry if it`s been said did`nt see it...

Why would you be using tape or a cut tube with a UST rim?

[Bryce]

the carpet tape thing sounds interesting... assuming you're not using a UST rim and a non UST tire. Give it a shot. Could be tough to get the tire seated properly.

back in the pre-Stan's day the watered-down liquid latex that I used would fuse the BMX tube to the tire as it dried. Never burped even with ill-fitting tire/rim combos. It tended to gum up the valve over time though.

I`m not using ust specific tires on the ust rims just non ust tires on ust rims.
I`ve heard sometimes they don`t seal and seep the stans or whatever your using around the rim. I`ve also heard they will burp air when the seal gives on landing or hard cornering with low pressures.

I`m using Dr Baron 2.5 wire tires on sunringle UST rims so I should have no worries since the sidewalls are super tuff, the heavy wire bead should help to.

This is my 1`st go @ tubless and after reading the headaches of others I only want to do it once so tape around the rim to help seal non UST skinny rubber bead to a UST rim sounds like a safer bet, just not sure if electrical tape would do or if Double-sided Carpet tape is the cats meow.

I`m going to try the stans sealant no need for me to add it untill I get a puncture so going to carry 2 small bottles with me untill I need them, this should save some coin & worries of it drying up, may need the injector tool they sell to...

Not sure how the 1st post got deleted but here is a look at the BMX idea minus the carpet glue around the bead to stop the burping & seepage.

Adding sealant now is much easier than doing it on the trail. Mec sell the injector

Some one has filled your head with myths. If the tires you want to use tubeless are not UST, you MUST use a sealant. They will not hold air and will go flat pretty quick. Steel beads make it more difficult to air up because they are stiffer and won't conform as easily.

Here's what you should do. No tape. Spray some soapy water on the rim and mount the tire you want to use and see if it will pump up easily. If it airs up, then you either inject sealant through the valve with an injector or pop one bead off enough to pour in two or three scoops of Stan's.

I have installed Conti tires, kevlar beaded ones to Stan's rims easily. Aired right up. Same with my wife's bike on UST Mavic wheels.

Carpet tape which is sticky both sides will probably make it far too difficult for the bead to move to work. Probably make it impossible to mount a tire that has a slightly tight bead.

It may or may not work depending on the tire bransd and the alignment of the planets, I tried non-UST nevegals on 819 UST rims with Stan's and they lost 10 lbs of air only every night

tape/rim strips/ stan's all weigh something probably 100-200 grams, so does the extra rubber in a UST tire probably 200 grams for a 2.35 and a tube weighs 200 grams

if I had it to do again running tubelesss on a UST rim I would just buy a UST tire

Thanks for the heads up guys. I did`nt feel like driving to far to get the stans stems & sealant so I mounted the front with a tube and took a shot & sealing the bead on the rear without a tube and no carpet tape around the rim wall, just cut out presta stem from an old tube put 2 layers of double-sided carpet tape between it and the rim & tightened it down. The stem did it`s job no problem with leaks, but the tire would no seal the bead no matter what i did.
Wrapped a piece of rope around the tire down the centre of the tread and got it as tight as I could then stuffed rags between the rope & tire to get the tire to open even more but even the high pressure at the gas station did knota dam thing...

I gave it a good go but the Der Barons are 2.5 and fresh off the line so no flex yet, maybe after a couple weeks of riding I`ll give it another go.
Still not sold on the tubless just mostly curious to see if all the hype is really that noticable. My PSI is not super low I run 20 psi in the front and 25 psi in the rear and never get flats when I keep the pressure there and don`t let it get any lower. I mostly do slower tec stuff with small drops, jumps & soft tires are the cats meow for me

Some guys online were saying these tires are crazy huge, I did`nt find them that much bigger than the 2.35 Nevegals that came stock on my 2012 Norco Range 2 and there is still lots of clearance.
1st thing I noticed was how super super gummy the knobs are & how they mold and deform also almost as sticky as bubble gum, I can feel the rubber trying to stick to my fingers when I pull away !!!

Listen to oldfart. In this case, a senior's wisdom is dead on target.

No doubt.

Any trick how to get a bead to seal? I`m thinking maybe a ratchet strap would be the best option just not sure how wide it needs to be, guessing just enough to squish the centre down but still push the side walls out... Probably want to put something between the racketing area and the tire to keep it from bind or biting into the tire though??

I rode with a couple guys that use laytex carpet glue to seal the bead on there wheels so this might be the best option for me, then if it holds I could use the stans when needed if the rubber does not seep air through the pores that is but another option to help with that would be to hit up an adult toy store were it`s the cheapest and buy some liquid laytex and brush it on to line the inside of the tire, or maybe thats a bad idea to as it would add weight.

Anyone think of a reason why laytex carpet glue would be a bad idea to seal rubber to rims? I think they were only using it to seal the ghetto bmx tube idea to the rubber tire.

If I can`t get it to seal I will try the carpet tape as it`s thick and super gummy, if I put some powder on it should make it easier for the tire to move and seal. I`m mostly just after the thick cushy gummy seal between the ust rim and non ust tire so the sticky is not needed on that side and this may help seal up a stubborn tire, or not?.?.?.

Thanks for the feed back, any insight helps...

Should have just bought UST rubber, I really wanted the Der Barons though and got them for a killer price on CRC, bonus I got free shipping and no duty taxes...Total was $138 for front & rear. just signed at the post office.

Quit fucking around with carpet tape and glue. It's a bike.

Get the proper valve stems. Mount the tire and spray the bead with winded or soapy water. Take the valve core out. Use an air compressor with a blow gun nozzle to quickly inflate the tire and seat the bead. If you're really having problems, try seating the bead with a tube in there. Then pop one side, pull the tube out, put the stans valve stem back in, now you only have to worry about seating one side.

It helps if you start with wide wheels. Mavic 819's are too skinny. They're wonderfully light and great for taking up space in the garage but useless for anything but pedestrian cross country riding. Been there....
A UST tire has a square edge bead that goes "snap" when it seats. A non UST tire won't seat the same way.
Despite having UST rims, the tires and wheels I use are all ghetto style tubeless. Never had a problem.
They're a major pain to remove though, so I just cut them off the wheel with tin snips when they're worn out.

[T-rex]

Thanks for the insight, great advise.

The Der Barons did snap into place like the ust tires were discribed, not sure if was just the wire bead adjusting but it sure make a loud tight snap around 40 psi. I`ll try popping the one side and removing the tube and see if that works, just need find a way compressor with a blow gun.

These tires also had the strightest line I`ve ever seen on a tire I`ve mounted, they seated perfect with no effort on my part just snapped in place nice and true, no wobbels anywhere...

Some non ust tires don't snap in place. Many do. The snap is dependent on fit not the shape of the bead or what it is made from.
