It might also have a yellow dot on the side of the tyre as well.
See the section "Coloured dots and stripes - whats that all about?" in the following link.

By the way, it's the yellow dot that's supposed to be aligned with the valve stem.
The red dot is the high spot of the tyre.

I understood that the red spot was to indicate the hight spot of the tyre and should be mounted against any low spot of the wheel (out of centre) (not so common nowadays).
Yellow spots indicate the light part of the tyre and gets mounted next to the valve.
Motorcycle tyres certainly still use yellow markings.

These things are always so confusing!
I just got 2 Michelin Primacy HP's (which, from another thread he's written, are same make and model as OP's) from Costco. Neither had red/yellow dots on (I looked for them) but one did have a band around it.
I've seem comments that this is to do with the run-out of the tyre but others saying that's rubbish and it's simply a stock-keeping thing for the manufacturer. I asked Costco and that's what they said it was a stock thing too. But then why does one tyre have a band and the other doesn't? Shrug!

I did wonder if it meant outward-facing side, and worried that I had fitted the recent set the wrong way round. But then I noticed the tyres have a red dot on both sides.
So that seems to dispose of the next-to-the-valve theory.

I used to run a mini with Yokahamas on it, they always had red dots.

Just to confuse things even further when I used to be involved in racing Coleway used to do two types of remoulds, one red spot and the other white - they were different compounds I believe - the white being softer if I remember rightly...

"Yellow spots indicate the light part of the tyre and gets mounted next to the valve." I agree, that's what I have always read, although hardly any tyre fitters do this, National tyres did when I used to use them before they did a Kwik Fit price match.
