Had my front tyres changed but they must of never balanced them well I told them to as well. Is it best to balance then take off and balance again sure read this somewhere

Hi Bob,

 

Hope you're well. They would normally take them off of the car, balance them and refit them....that should be enough I would've thought!

All I'd say is that make sure the tyres are inflated to the correct pressure before balancing.

 

Cheers, Steve.

Also, most tyre companies have far too high initial balancing forces, ie any out of balance forces below 150 grams gives you a zero reading,  anyone who knows about balancing will also know that a quick balance followed by an absolute zero reading is not possible.

A tolerance of 5g is acceptable. They probably never balanced your wheel, or somehow not put in the correct details on the machine.  I've never had a problem with ours in work.

I have a set of Yokohamas on my 1976 car.  I fitted them myself (have a machine) but have never had them balanced and don't get any shake that I can feel.  Any problems leaving them well alone?  There are no weights on the wheels at all.

Tolerance of 5g ?  but what is your initial setting ?  I guarantee it will NOT be true zero  every machine I have ever seen has an initial setting....  that is how it is so easy to get readings of zero because as long as it falls within the initial setting you will see zero on the gauge !  yet the true reading could be as high as 150 grams before you start to see any numbers other than zero

Hi Boycie,

 

I have a set of A032's on my Mini, they're on those alloy Cooper replica wheels, which are very well made. The wheels/tyres have not yet been balanced but even up to 70mph (my ears can't take any more above 70!) on a test run there is absolutely no vibration or shake, so I guess no wobble means good balance so you should be ok.

 

Cheers, Steve.

will take back tommorrow get them do them again

 

if still not right will take them to a place with a new good balancer but its 8 miles away

 

i would have taken it there to start with but he doesnt fit tyres

 It shows a reading of 0/0 if you use the machine with no wheel attached. I guess you never really know how accurate it really is.

Yes that is its static position, it means that the sensor could be reading upto 150 grams of out of balance force but will still only show the operator o grams force....  this is to allow speedy balancing but not suggesting yours are set that high as most seem to be set at about 50, some major companies are set at a higher initial zero point but anyone who does motorsport would be crucified with these initial settings and a motorsport machine would be a lot tighter, you can of course get manual true reading machines but they are not often seen nowadays.

 

The machine is totally accurate to maybe 0.5grams but you would be there all day trying to get a wheel off a production car balanced....  some top end balancing machines have a "road wheel roller" this road wheel preloads and as its rotated it can measure the out of roundness, check the true roundness of the rim then suggest a better position for the tyre to get the best roundness of the assembly then allow you to balance it and get better readings, Aston Martin have some of these not sure how many but they used to have 2 in their Gaydon workshop.

Is there any questions I should about there balancer so I know it's the best or very good

What's the preset weight of 0 reading
