Title: Balancing tires with full floating (rattling) rotors
Post by: battlecry on January 07, 2011, 10:04:30 AM
I'm mounting new tires next week and plan on doing the rear with the fixed rotor and chainring on a Marc Parnes balancer.  I'm thinking maybe I should balance the front wheel/tire without the full-floating rotors.   Do the rattling rotors mess up the front wheel balance?

That was not an issue on my bike. Not saying it couldn't be, but I doubt it.
The floating is sideways.........

I agree

Thanks, are you guys saying you balanced the complete assembly, tire/wheel/rotors because it made no difference or wheel/tire with rotors added later because it made no difference?  I've seen videos of both ways, would have thought balancing the complete assembly made more sense.

Balancing the complete wheel makes the most sense, whether or not there are floating rotors.

Honestly, the weight and diameter of the rotors make them minor contributors compared to the wheel and especially the tire.

I've always balanced the complete assy, because like Nick says it makes the most sense.

I don't even bother with rears.

I've balanced probably twenty sets of tires on my SS with floating front rotors over the years, always with the rotors in place.

Hope that lends you some little peace of mind.

all of my race bikes have full floaters and its never been a problem, even with my tard wheels that only have 1 rotor and tubes. [bacon]

Are you saying you don't bother balancing rear tires?

That is exactly what I'm saying. My own anyway. I'll balance someone else' if they want.

Most balance problems are associated with the wheel, not the tire. I think it's a waste of time.

Well, yeah, the wheel.  Do you balance your own rear wheels?

I check them once.

If they don't require any significant weight I never do again.

intersting.  the tire guys at every track make fun of my monsterwheels and the amount of weights that they seem to take to balance properly, and they like to make fun of how heavy they are. [bacon]

I run Michelins.

Maybe your wheels are as bad as the tire guys say then.

The stock front wheel on my Monster never requires more than 1 weight, and as I recall the rear was the same. I don't balance it any more.

I love the Marvics on the 996.

They need paint as they've been around a while.

Good luck with them.
