What do the red and yellow dots on a tyre sidewall mean?

When tyres are made they are not perfectly balanced nor perfectly round.

    Wondering what the red and yellow dots mean on your brand-new set of tyres?

    When tyres are made they are not perfectly balanced nor perfectly round. The red dot on the tyre sidewall marks the point where the tyre is the lightest on its radius, and therefore the tyre fitter should align this mark with the wheel’s tyre valve — which is the heaviest part of the wheel. When the tyre is fitted this way, it will need fewer weights to balance it.

    The yellow dot marks the tyre’s high point — and this mark should be aligned with an indent on the wheel, which marks its low point (because wheels are not made perfectly round either).
