Yeah, it's that simple. I use two 5-gallon pails / buckets, turned upside down. I also just use the bike axle. Works fine. Easy, convenient, fast and inexpensive.

I use a plastic outdoor chair upside down with a couple of holes drilled in the legs but don't tell my bride.

For those in OZ the rear wheel will fit on the diagonal in a large wheelie bin I have not tried the front.

Why does it take 10 minutes to give 2 minutes of explanation. I don't need the artsy shots of the HD dealer and road pics.
Like Jack Webb, JOE FRIDAY. used to say," just the facts m'am."

IMNSHO, I think the effectiveness/accuracy of balancing this way is influenced by how "free" and "true" the wheel spins. There is a lot of things that can impact that. eg. stiff bearings, uneven/unlevel surface of stands, etc. When all is said and done, it may not make a big difference but.......in the video, his balancer did not agree with the factory. He automatically assumed the factory was wrong. Kinda makes you go Hmmmmm.

Static balancers work well but the ones that use cones to center the wheel on the "axle" of the balancer and then the axle rests on knife edge bearings pretty much eliminate any artifact that could be introduced by the "homemade" method.

These balancers are relatively inexpensive.

I have a Marc Parnes balancer and, while it's pretty nice, I think balancing it on the axle is plenty accurate, especially in light of the fact that some guys don't even bother to balance their tires at all, with no decrease in performance. I balance mine out of habit, but every time I change a tire I'm tempted to just skip it and see what happens. Even when they are balanced, how long do they actually stay that way once the rubber starts wearing off?

I asked this same question in a different thread and Brockie was nice enough to respond, but may be lost in thread drift, so I'll ask again, see what others think...

What do I look/feel for if the tire is unbalanced?

If no symptoms, any reason to concern myself with balancing, easy enough to remove the wheel now that I'm getting more comfortable working on my on bike, very satisfying by the way...saving $$$ to boot

The biggest symptom of any rotating mass that isn't balanced is going to be vibration. It'll be different than the vibration you feel from something like a knobby tire, which buzzes even at low speed. For an out of balance tire, you won't notice it while you're cruising around a parking lot at 15 mph, but the faster you go, the worse it would get. How bad it gets, and how long it takes until the vibration is noticeable, would depend on how out of balance the tire was.

I'm not a physicist or engineer, so I don't know how much weight it would take in an out of balance tire to create that effect. I've never used more than an ounce of weight (four 1/4 ounce wheel weights) to balance a tire. That's about the weight of a half of a hard boiled egg. I honestly don't think that small of an amount of weight (28 grams) will make a lot of difference in a tire that weighs about 17 pounds (the weight of a rear Shinko 705) and isn't spinning at 10,000 RPMs.

If you're really curious, try this easy experiment. Balance your tire and put it on the bike. Now mark where the weights are on a balanced tire, and move them to the opposite side of the tire. Now the tire is going to be out of balance by not only the weight of the heavy spot of the tire, but also by the weights themselves. Now, go ride the bike at a brisk pace, and see if that "doubling down" on the heavy side of the tire makes it vibrate. If it does, now you'll know what it would feel like, and once you know, you can move the weights back to their original balance point without having to take the tire off and rebalance it. If you don't notice anything, then you'll know that balancing the tire was actually a waste of effort in the first place.

I may try this experiment myself next time to see how necessary it is to balance a tire.
