The humble dot: the coloured circle of a million uses. Whether its polka, separating website names from www and com or providing a nickname for Dorothys everywhere, the dot is hot.
You may have noticed (possibly during your last DIY tIre check) that there are yellow or red dots painted on the sidewall of your tire.
So why are they there, what’s the difference and what do they mean? The answer is actually surprising.
We grabbed our Shop Manager SALAH to find out what the deal is with those yellow dots on the tires.
Known to the tire industry as ‘balance dots’, the dots are there to guide tire technicians as they mount fresh rubber to wheels. When matching a tire with a wheel, the chance of perfect weight distribution is very, very rare (though our NanoEnergy3 and Proxes C100 plus tires normally require minimal weight to balance).
This means tires and wheels need to be balanced. Correct balance prevents vibration which is the major culprit behind a range of issues, not least increased noise, driving discomfort and uneven tire wear.
The yellow dot indicates the lightest part of the tire sidewall.
On a wheel or rim, the heaviest part is generally the valve stem. During fitting the yellow dot is aligned with the valve stem of the wheel. Having the dot and valve stem in alignment means technicians won’t need to use as many balancing weights.
Fewer weights and a more balanced wheel mean a quieter, more comfortable ride and a longer-lasting tire.
