I scroll through the internet on this subjuct and many times i've read their's no need to balance motorcycle tires. I put my car tire on last time and it wasn't balanced. It rode good and had worn even all the way around. I didn't balance this last one I just put on and I hope to get over 20k like the last tire

I balance my own and about 60% of the time I need "no" balance weights. But, to achieve this you must find the heavy spot of the rim and the light spot of the tire and match them up. Otherwise it's just plain luck... This has worked with both MC & CT mounts for my Valk Amended: Oh, BTW the valve stem is not necessarily the heavy spot on aluminum wheels. My heavy spots are 10" & 13" from my valve stems. |

You DO need to balance motorcycle tires...unless you use one of the "balance beads" or ride-on stuff.
BUT...you don't really need to spin balance them.
The computerized spin balancers do a great job because they tell you what weight to put on AND which side of the rim to install it on resulting in a very precise balance for your automobile rim...but on our motorcycles (on all mine anyway) we put all the weight in the exact center of the rim (the clip-on or spoke weights) and so spin balanceing is overkill. You can do just as good a job with gravity rig like DFragn shows.

After 8 years doing the usual tire replacement & balancing successfully, last year I went with and installed DynaBeads. I have been very impressed that 1) the balance seems great & 2) so far no "cupping" especially the rear where I always got pretty bad cupping.

I used a static balance as shown above by Dfragn. The rear tire was way out of balance after replacement, but the front tire was perfectly balanced without the addition of any weight.
Sometimes you get lucky, but I would at least check to see make sure the tire was not way out of balance.

How do you find the light spot of the tire. I know the "tire stem dot" on the tire is supposed to be the light spot. Is that what you use, or is there a way to find it for yourself? |

How do you find the light spot of the tire. I know the "tire stem dot" on the tire is supposed to be the light spot. Is that what you use, or is there a way to find it for yourself? Most manufacturers mark the light spot. I use it as a reference only. Once the tire is mounted and before I set the beads I static balance and spin the tire on the rim a little at first to confirm the light spot or not (after I've found the heavy spot on the rim). Sometimes it takes more tire adjustments to zero it out. If you've gone 360* without zeroing-in it isn't going to balance out on it's own. So reposition to the area of least movement to and seat the beads. There's absolutely no need to sit there watching & waiting for a tire to stop spinning on a static balancer. I position it 90* increments at a time to determine imbalance and add weights. If I'm close to happy I'll double check it at 12 points (hand of a clock). If it doesn't move at that level she'll give you no trouble at the notorious 55mph imbalance zone nor at 120mph. SuperBike pit crews balance their race wheels on a static balancer, usually. |

No, I bought that a few years ago. The from whom escapes me (via Internet). Google Motorcycle static wheel balancer. A plethora of options will come up. That's the OE rear axle through the wheel resting on 2 very sensitive bearings on each side. Ah, here it is.Apparently it's out of production. http://www.webbikeworld.com/Reviewed-motorcycle-products/balancer/ |
