Back in the day when tyre balancing was done manually with a spirit bubble I was told that you positioned the dot in the sidewall on the valve as it compensated for the weight of the valve and used less weights. Looking at the photos it seems that with electronic balancing that no longer happens. In which case why do manufacturers still bother with the dot?

I was always told that the dot equated to the heaviest part of the tyre somehow and was placed either next to the valve or opposite (don't remember exactly which way round)

Yes they are.

I have replied by PM.

Thank you.

I suppose if it was the heaviest part it would be opposite. But as you said, Bluenose, no one ever seems to bother these days, and Porsche who installed these tyres certainly didn't bother. I haven't met a fitter in decades who has even considered this, and you'd think it would be in their interest to save som costs on weights, no matter how little they cost them. Interesting though.

When radial tyres first came along (until then it was only crossply) the heavy join of the tread cap caused balance issues. This being the heavy point with the overlap edge. So the paint red spot was / is applied to the position opposite - 180 degrees. The recommendation was / is to fit the tyre with the red spot adjacent to the tyre valve of the wheel. In theory this being the lightest part of the wheel. Bearing in mind that this was in the era of the (crude) flat table bubble balancing machines.

Today's very sophisticated computerised and extremely accurate tyre balancing machines negate this need.

Just as well with alloys up to 25" in diameter with ultra wide and low tyres!

Thanks for that Steve, these nuggets of information make all the posts of waffle and indecision bearable! Also too me back to buying remould crossplies for my Mini 1000 at about a fiver a go. How times change, no change from a grand at best now.

Could have done with them. Currently in the Lakes and completely snowed in. Abandoned cars everywhere.

I used to scrub through those 10" Mini remoulds every 5k. I suppose squirting Redex on them to generate wheel spin smoke didn't help
