Quick question about tires and rim changes...

So heres something thats been bugging me for a bit, did some reasearch and didnt find exactly what i wanted to know. So the question is, If i change the tire on the rim, must i re-balance the wheel? Im assuming no, but i could be wrong. I will be changing to the exact same tire that it has been currently balanced on.
That is all :P

Any help will be greatly appreciated. im sure this will be a quick one for you moto mech's out there...
 
You will need to re-balance. I assume if you could get the tire back on in exactly the same location on the rim then it wouldn't need to be, but it's better to check.

If you don't want to balance, just remove the weights and put in dyna beads, I have them and I've never noticed a single issue with them.

Hmm just saw the demo video of dyna beads... very cool! of course its quite simple physics... why do tires/wheels not come with these from manufacturers! like wtf? Thanks for the suggestion btw, i will look into them. I just realized i cant order my tires from the states :( so im going to need to find them locally which will run me 175% more :'(
 
Look up pete's superbikes in montreal, awesome guy to deal with, awesome prices and very quick shipping. I had one of the very first shipments of the pilot road 3s last spring from him.
 
+1 to pete's, if your ordering tires and asking about balancing, I'm assuming your changing them yourself? The reason you balance a tire is because a tire is never quite manufactured 100% symmetrical. Tire weights offset the "light" spot in a tire. Hence if you rotate/move the tire on the rim, you will also need to move the weights. Different tire, different light spot, different amount of weight usually required.

You can build a tire balancer for $10 from princess auto. A 2x4 and 4 ball bearings (about ~$1.75 each). Remove the grease seals from the bearings, soak in a bit of varsol or kerosene to remove the grease (you want the bearings to float as freely as possible), a hole saw to cut a hole in the 2x4's for the axel to slide through at the top, and your done. Little WD40 in the bearings and spin them around before each use. Works like a charm. Get some wheelweights, the heavy spot will always float to the bottom, offset it with weight, spin the wheel, repeat until the wheel no longer appears to come to a rest at a single spot.

Do some more research on dyna beads before deciding to use.

Perhaps there's a reason why no tire manufacture recommends them.....

A lot of people are very sceptical about dynabeads, because many claim that the beads do not behave as promised. For example, in hard acceleration, the claim is that the beads will just get stuck in the 'back end' of the tire rather than ditribute evenly, and I'd believe this claim. I had beads in my front tire and the person who was putting new tires on really didn't like them, I agreed not to put them back in. I am pretty happy with a wheel which was 'old school' balanced.
 
I've never balanced any rear tire I've EVER installed on a bike and not had an issue. Never used Dynabeads. Used tire slime once (not to balance, lol).

I got a demo from a guy who showed me how much the cush drive messes up the balance anyway and told me balancing the rear was a waste of time :)
