Wheel Balancing

[Mike]

What would be the reason for a wheel calling for 130 grams of weight to be balanced ? Did the front and it needed 20 grams. These are new Avon Cobras. I thought there was a maximum weight you could use.

Thanks

I've heard a lot of good things about dynabeads.  I bought a bunch but have not been home long enough to install them.

Before I mount the tire,I find the heavy spot on the rim..mark that with a sharpie..then mount the tire and find the heavy spot..then rotate tire 180 so the sharpie mark and heavy spot on tire are across from each other...sometimes that balances the tire..if not I use dyna beads...rock on dennis

The best reason would be the balance job got screwed up somehow.
But several of the other suggestions are quite valid. I also spot the wheel and tire heavy spots opposite. Rarely do I need weights at all. The Dyna beads work. I hope it's not really 130 grams off. That would be a bad tire.

That's kinda high. When I balance mine I've never needed more than 15 grams (1/2 oz.) and more often then not I don't need any balance weight. And, I've always been good to 115 mph. But then I find the rims heavy spot first  then position the tire accordingly.
This method has worked for Avons, Metzler, Dunlop and a GoodYear car tire.

MC tires because of their reduced width should be easier to balance out then a wide car tire with a heavy run-out.

Todays tire manufacturing process is very precise [incl. mc tires] and although it's possible to have a bad tire (bad run-out) it's not likely.
If auto tire changers bothered to locate a rims heavy spot most car tires wouldn't need any or much balance weight either.

How are you balancing? Static?

Dynabeads here

Those electronic balancers are about the best way to get the balance job screwed up. They in part depend on input from the user about the wheel size and sometimes related info. If not done correctly, they will give very poor results.
I would use a static balancer, or cobble up some stuff to use the axle. At the least you can check the work of the balancer.

Are you sure all old weights are removed..??..

Gabage in, garbage out as tehy say!

Where'd you get that balancer in your pic?

For the static balance, I just use two saw horses and put a couple of 2X4s across with the tire on the axle between the 2X4s.  I add a few nails to keep the axle from moving.  The tire should spin easy on the bearings (if not, I would look at replacing the bearings).

I draw a circle and plot where the valve stem ends up on each spin.
