I'm about to mount a new rear Storm. Question is the old BT020 has a dot on it I think that is supposed to lined up with the valve stem. My new Avon doesn't have anything like that. What do you Avon guys do?
WOW Byron, I hate to admit it but don't even have a balancer yet. That was going to be my next question. What brand is good? My son is on a ZZR site and he posted a question about balancing and got a lot of responses that many don't even balance but I figured I would get a balancer for the sons and me so we could. He also found some strange looking rigs for balancing by guys not wanting to spend big bucks on a balancer.Apparently Avon feels that marking the tire is not worth their expense to do it.
Now, standby for what this anal-retentive guy is willing to do.
- After the old tire is off the rim, remove any old weights and throughly clean the wheel.
- Put the wheel, with valve core and cap, on the balancer and find the heavy spot of the wheel and mark it. I use a small piece of painters tape. Also, make sure you have all the water out of all the wheels cavities.
- Now balance the wheel. This is temporary so just use painters tape to hold the weights in place.
- Mount the new tire and put it back on the balancer. Mark the heavy or light spot of the tire, your choice. This is the tire only because the wheel was balanced, remember.
- Now this is the fun part. You get to let the air out of the tire, break the beads, and rotate the tire so the heavy spots (wheel and tire) are opposite. If you marked the light spot (top) of the tire, line it up with the heavy spot (bottom) of the rim. If you marked the heavy spot (bottom) of the tire, position it opposite the heavy spot of the wheel.
- Now re-inflate the tire, remove the wheel balance weights and balance the whole assembly.
This will give you a balance with the least amount of required weight. Directly from Avon; "Anything over and beyond 2.5 oz (71 grams) would be considered excessive to balance on such tires and would be considered for a replacement if within the first 0.5mm of original tread new tread depth."
Unless you take the time to mark the heavy spot of the wheel then balance the wheel before mounting the tire you have no way of knowing where the weights are in relation to the tire and wheel. You simply balance the assembly. If it takes what you would consider excessive weight you can reposition the tire but without reference points it's just a crap-shoot.
One of the things you will find is that the heavy spot of the wheel is not necessarily where the valve stem is. This means that if you take the time to find the heavy spot of the wheel you can adjust the position of tires that are marked and end up using less weight to balance them.
So how was that track day?I have a newer set of STorms on STick right now with no weights. Seems fine to ~125.
