Bead balance

[twocool]

Funny...when you read up on this method on the internet...I find one fact amusing:

They say that if you throw the beads into your tire, and then run the tire on a computer balancing machine, that the tire will not indicate that it is balanced, at any speed...

They say the beads only work "on the road"....hmmmmm

Pretty smart beads ..that they know when you are trying to fool them on the balance machine....

They also say the beads don't work at low speeds, a tire balancer doesn't spin very fast.  I assume it is similar to having a bit of water in a tire.  Every time you spin it on the balancer it will give different wacky readings because the water moves.

Completely unrelated to the topic but while we are talking about tires:  NEVER use fix a flat type stuff unless it is a total emergency!!  Once that stuff is in a tire it will never balance correctly again. And if you have a newer car where the valve stems are radio transmitters for the tire pressure monitor system, the fix a flat ruins the sensors (about $100 a piece to replace).

    Lots of questions left unanswered.........

    Did they leave on the balancing weights from the conventional balance and then add the beads??

    Were the guys who did the conventional balance idiots??  (conventional balance seems to work for eveybody else...)

    How could it NOT be the tires?  I mean if the tire were balance in the first place, you wouldn't need balancing........

    I never heard of a tire which was immune to balancing by conventional methods...until now...

    10 oz per tire??  Holy crap.....my motorcycle needs ony 1/4 ounce on the rear, and 3/4 oz on the front........I don't want half a pound extra in each tire!!!

    Are those tires "stock" or even recommended on that truck?  Or "home brew" custom oversize etc???

    Most people who say the beads work, say they will work on large truck tires but not on small car tires..(or motorcycle)

    Do we go straight to the tard farm now?  Or let this realy heat up and let every get really pissed off?

you never leave sticks on weights on when using beads. DUH......

again, rims where balanced at the tire and rim shop i bought them from. when i got home i took it to another and lastly i did a shop who road force balanced them.

it might not have been the tires. it could have been the rims.

if you havent heard of a tire hard to balance until now then you obviously dont ride big tires. some all/mud terrains have these issues

my tires weight about 80lbs each (not counting the rims). i know thats a big difference from a bike tire but 10oz is a drop in the bucket for my rims and tires

stock? recommended? homebrew?

no truck on the market comes with 24"tires so obviously they are not stock. is a katana rim recommended n a gs500? sure it fit and spins and clears, but from a technical safety or engineering aspect, is it recommended? probably not. but if we secure it in place and balance it, where is the problem? same goes for rims and tires on a 4 wheeled ride also. WTH is homebrew?? LOL. I dont make my own tires

no need for the tard farm. were all civilized and educated here.

Moved the discussion here......

OK so it worked for you....on big truck tires...most agree that beads work well on truck tires....most say beads do nothing on motorcycle...not appropriate..

"hombrew" means using aftermarket parts, which are largely untested and unproven..often giving poor or unexpected results....

actually, I think they say the tire needs to be free to "bounce around" like on the road, rather than being held fixed onto the balancing machine....

But old fashioned weights work at slow speed and at high speed.......small tires and big tires...

Beads seem to have too many limitations for my liking...

I used "slime" only once to fix a flat on my "razor" electric scooter...It's held for 5 years so far...I hope I never have to take that tire off...  I guess if you're stuck in the middle of nowhere you're gonna use whatever gets you home and worry about the cost and trouble of fixing up everything later...

I'm still left with one question...Why didn't conventional balancing with weight work?

A tire can be balanced (no significant heavy spot) and still have a major vibration on the road if the tire is out of round (or the wheel is bent).  As a gross example imagine an egg shaped tire on an axle.  You could add enough wheel weights to the smaller (lighter) end to make that egg perfectly balanced.  Even perfectly balanced, the egg shape is not going to roll very smoothly.

All that said, it doesn't explain why the dyna beads worked in this case.

The out of round makes sense that a balanced tire/wheel might still shake or vibrate........I've also seen tires not fully seated in the rim giving a "low spot"....Then there is dynamic balancing vs static balancing..........I figure dynamic doesn't much matter on a motorcycle, but might on a car, especially with low profile wide wheels/tires...

Do beads "dynamically balance"? or only static balance?  Or nto really do either??



But this is different from balancing....

And...you already asked my follow up question......how did Beads fix a problem which balancing did not???

^WTF?!

[weedahoe]

because my pirelli 325/45/24 tires are all terrain tires and run something 20/32 of rubber. They weight 80lbs each. Your tires on a normal truck or car are much smaller and lighter and have less rubber (street tires). Mine are Load E and 2 ply i think (i would have to go read the sidewalls). They take 65psi to fill. My tires arent normal tires by any means. This is why no normal shop could balance mine and thus why i used 10oz of beads per tire

[GI_JO_NATHAN]

Yeah there's also the issue of the weights being on the wheel, but the mass of the tire bing further out. I've thought about trying this on my ranger. I'm running 325/60-18 Nitto's. And they don't ever feel balanced.

[weedahoe]

Nitto makes some nice tires and are very popular. I wanted the Nitto Trail Grapplers in 24's but they wanted 3 grand for just the tires. Being in had JUST bought mine,  i couldn't justify the expense.

However, big difference between truck tires and bike tires. With that being said,  no reason atall you cab use just beads in a bike tire and be fine.
