I recently had 2 new tyres fitted to my van. The new tyres had a little yellow circle printed on the sidewall and this was aligned next to the valve. I believe this is to match the lightest part of the tyre (yellow circle) with the heaviest part of the rim (valve) which will help to balance the wheel.
During balancing 80g of weights were added exactly next to the valve. Some, or all, of these weights will be there to compensate for the adjacent lightest part of the tyre. If the tyre was deflated and rotated 180 degrees on the rim the amount of weights would be reduced or maybe there would be no weights needed.
If I had a balancing machine and was doing this job at home then this is what I would do - rotate the tyre on the rim to eliminate the need to add weights next to the lightest part of the tyre. I think this would be doing the job correctly.
The tyre fitter has not done this so I have a wheel with possibly 3 unnecessary weights on it.
Has he done a good job?
