Hi all,

Need to know size of hole in middle of wheel to advise tyre fitter to see if they can fit it on their balancing machine.

I would go and measure it but - am away from my beloved today.

Anyone know the hole size?:thumb
 
Original concept.

Thanks for your reply. Most helpful.

If you could confirm "a proper tyre fitter" who can definatly balance the rear wheel within say 10miles of Chippenham in Wiltshire that would be great. I await your reply with bated breath.:)
 
I've just been to the shed to measure the hole in my spare ALI rear wheel. It's 62mm diameter. I would imagine the spoked wheels have the same hole size in them.

I never bother balancing my rear wheels. Hardly ever do fronts either.

Hope this helps.
 
Serious question......why not? :nenau

I fit my own tyres, but can't balance them. I've only ever had ONE front wheel that was noticeably out of balance. I got that balanced at my local bike mechanics/shop. It was WAY out of balance. I could see the front forks moving front to back at certain speeds :eek :eek

I've not changed the front tyre on the GS yet, but time will tell if it needs balancing.

In all the years I've been fitting my own tyres, I've ridden a Bandit 600, KTM LC4 SM, ZZR 600 and a DR650 SM (home conversion). So a wide range of bike styles. Only the ZZR needed doing, and only once.
 
Oh ok, that makes sense.

Just thought that'd be an important thing on a bike to have the wheels balanced :nenau what with the gyroscopic effect?....or am I just being naive?

I once had a balance weight fall off a front wheel.....and I never noticed that it had.

In my personal opinion and experience*, I think it's more important on a CAR as you will get wheel wobble/shake if the wheels aren't balanced correctly.

On a bike it doesn't seem to make any difference, unless the wheel is MASSIVELY out of balance. I suppose if your name is Rossi, Haga or Fogarty then it might be noticeable.

As long as the tyre is fitted correctly (the coloured dot put adj to the valve) then it should be OK.


* I am NOT a mechanic. I'm not a gynaecologist either, but I do pay an interest in it..... :augie

Bike Treads in Swindon could do it but admittedly they are a little further than 10miles away from Chippenham

I'm with Miff on this ....... the chances of the wheel being miles out of balance are very slim provided the tyre is fitted correctly i.e. yellow dot next to the valve :thumb2
 
Thanks Guys - perfect. Thanks Miff your a star.

Did use to use bike treads at swindon but seem to be rather "enthusiastic" with their pricing at the moment!
 
r j,although many gsers dont bother balancing rear wheels they can be done on all modern wheel balance machines,the tyre fitter needs to know how to set the machine for "static" balance (rather than dynamic balance) this will then give just one placement for the wheel weights,the standard popular car cone will fit the gs wheel but i normally fit the cone "machine" side so the wheel fits on it (rather than screwing the cone onto the wheel)this mounts the wheel to the shaft better and reduces the risk of damaging the paint finish.hope this makes sense,try and find an independant garage ,chances are they will have a better understanding of how to set the machine up, mike

Seriously. Use a proper tyre fitter. Or does travelling more than 10 miles on an bike cause you a problem? :rolleyes:
 
Never balance tyres either and havent needed to. If there are weights on the wheel already I leave them on and fit new tyre. After some experimenting years ago I found it was generally the wheel that was out of balance, not the tyre. If the dot is put in the right place the tyre will be balanced assuming the wheel is ok. I never change the valves either unless there is a problem with them and even then I only change the core and not the whole valve. The whole balance and new valve thing at tyre fitters is just another way to fleece you along with the disposal charge.
 
The rear wheel will fit on any car wheel balancer ,as I have just fitted and balanced one myself the front will need a motorcycle wheel balancer hope this helps
