I was looking at the new set of tyres for my m50d and came across this * marking on pirelli's website, what's the difference between * and *1 ?

BMW OE tires have a star on the sidewall.

That's a star marking - yes I am aware of this, however I now can see another marking as per my post. And I do wonder what does that mean if tyre has *1 marking.

Is this what you are referring to? If yes, I'd call Tire Rack. It looks like something Tire Rack did to know that this is a new version of the tire.

I emailed pirelli so will see what they say.

This is the explanation I received from pirelli's customer service regarding the *1 marking:

I can confirm that the *1 means that the tyre has a more lower rolling resistance which means that the tyre can roll longer before the resistance makes the tyre come to a stop.
