Problem with EC wheel (mounting and discoloring)

Those that are using beads, do you air down often? Does the bead get in the way of airing down?( clog the valve stem)

Yes I air down and up regularly and have never had a problem. You can't put the beads that I'm using in through the valve stem and have to break a bead to put them in. There is also a special valve available that has a filter end on it that is suppose to stop even "tyre sand" from being a problem.

The issue we had was as the beads broke down and created some dust, that would absorb moisture and forming big lumps and therefore they couldn't do their job of balancing. I would always use a portable compressor, therefore without a tank or any form of water trap. So as you can imagine, air straight out of a compressor pump creates quite a bit of condensation in your tyres. So I guess if you only air down a little it might not be an issue but as we would air down a few times every day, we found the amount of condensation mixed with the older style beads was a real problem and we never tried them again.

That is a problem with glass, ceramic or plastic beads. They break down from rubbing on each other. Moisture has not been a problem with mine but I will say that I might only change pressure a couple of times a day when I do. Not saying it won't happen but hasn't yet.

Hi guys- Back where there is internet. The remounting of the weights to outside of where they would rub on the front rotor worked like a champ for about 80 miles. Then I heard a bling, bling, bling and the steering wheel began to shake again. Not nearly as much, but Beads sound pretty good to me right now. I will have to say- I love Newfoundland- but their roads are gawd-awful. Give me dirt or gravel any day.

Ski Freak- sounds like a good idea- never thought of them- never had a wheel that needed to be reversed when you rotated them. Live and learn.

Hi Yves, How are you mate?
.
My experience with beads and "airing down often" hasn't been pleasant.
.
Because of where I live, the most common off roading we do is on soft sand....this time of year Fraser and Cooloola are amazing and on my doorstep......so of course, airing down is just part of it. My experience admittedly was with earlier balance beads not the newer stainless type. Maybe if I hadn't experienced those, I might be happy to try the newer types again but the main issue I found was nothing to do with clogging valves as you might assume....and in fact clogged valves never occurred with me.

Hi John, Doing good!

Thanks for the info, I have no experience with beads but seems like a good idea, just surprising about them not conflicting with the valve, thought for sure it would?? As for airing down, well I will air down for even a trip of say 5 km's for a more comfortable ride so end up airing up and down often, technology taking over I would assume the beads would improve and moisture not be such a factor so may be worth a look.

Hope all is well with you
Yves

Thanks Dan, Some one please explain to me how these beads don't get sucked into the valve stem and interfere with the seal in the valve stem? Why doesn't it happen? Inquiring minds want to know.... am I right to say that the beads you use are large enough that they cannot enter the stem?

I would think the beads sitting in the bottom of the tyre are not near enough the valve entry on the rim to get caught in the relatively small vortex? My thinking anyways..

I say that both of these answer are right. I've not had a problem and yes you can't put the beads that I use through the valve stem. Talking to the "Tip Top" tyre rep they sell tyre sand to balance tyres (can be put in through the stem with valve removed) and can supply a special valve that has a little filter on the end that stops the sand from getting into the valves. I have bought some of these valves but have not fitted them as I'm not having a problem.

I contacted the Fuso dealer that I bought the truck from- letting him know that I have not been able to keep the front tires in balance and curious as to what he thought? His reply was that he suspected that perhaps my Cooper St/maxx's were slipping on the rims. After that, I marked the wheels and tire so- but after about 100 miles of relatively smooth road (for Newfoundland) everything still lines up. But there is no doubt that I am out of balance.

Slipping on the rims? BS. I spent a few years bumping tires in a shop and have had a few issues with my FG. Wheel being bent, tread seperation or a very out of round tire are what comes to mind first. A person doing spin balance should be able to see what's going on.

Heh, that's a "don't bother me with your problems" answer.

From your photo, that seems like an awful lot of weights on the rim. How much did they add?

Okay back to internet. In Nova Scotia now- already pining for New Foundland. Just so we are clear- the dealer that sold the truck is not the person that mounted or spin balanced the tires. So- he has not seen the truck ever (he delivered it directly to my daughters house from the port of entry) and just trying to help. As I said, after his comment, I marked the all four wheels and tires to see if there was any movement. After about 180 miles, I believe their is as much as 1/64 of movement on the front tires and the right rear- left rear none. The wheel looks is slightly ahead of the tire in all cases. I will continue to observe and see if my observations continue. If they do- stainless steel balancing beads would make a hell of a lot of sense.

Just so I am clear- tires originally mounted on EC wheels in Colorado. Some wobble and braking indiosyncrasies, but as the miles went by it smoothed out. Popped right rear tire in northern Newfoundland and a 3 week wait for a new tire. All tires balanced and rotated. Right away I could hardly hold on to the wheel and braking was horrible. After 2 miles returned to tire dealer and discovered the need to put the balancing weights as far to the outside to keep from keeping wheel from seating on hub. Rebalanced and remounted tires. Perfect for first 80 miles, then steering wheel vibration. Went back and both front tires were out of balance. I watched the guy balance all the tires the first time and then again this time. Left shop and from the beginning there was a little wobble. Got worse each day. Then I marked the wheels and tire and this is what I have seen. I was a tire jockey in my youth on Kodiak, Alaska 40 years ago, and I don't remember tires that were appropriate for the wheels moving either- but you now know what I am seeing.

Myself, I'm of the opinion that there is something else going on. Do the wheels spin true on the vehicle when it is jacked up.
Some wobble and braking idiosyncrasies
Should never have happened. Got to be another problem.

try rotating them to see if the problem goes away. I was in the market for a steering stabilizer due to a 50 mph death wobble and difficulty braking...finally took the wheels back for a balance check. They were way out of balance...the shop couldn't figure out how they ever let them out in that condition. No longer needed a steering stabilizer. My hypothesis is that the COE design tends to magnify the implications of an out of balance wheel.
