Balancing your tyres is something you can’t do yourself, you will need to take your tyres for tyre service, where they will take your tyres off and put them in a rotating machine that measures the side forces on the tyre, the machine calculates what weight should be added to counteract these forces and balance the wheel. When the weights, which should be environmentally friendly and not contain lead, have been added the wheel should rotate smoothly. When you change between summer and winter tyres, or just rotate your tyres at a tyre service station, they will check if the tyres are balanced.
