Easy to say
Primacy touring range
PS sport range
XM eco tires

Which is better for you depends on your driving, your vehicles, available sizes and your money.

PSS terus

There is no primacy 4 ST, never seen or heard of one before.
Maybe they put the ST sign so that ppl don't confuse PS4 and P4.
So far never heard of Michelin fake tires for cars.
But for bikes I've encountered some maybe fake ones, but actually it is older models or for other regions.

But seriously, I don't want to confuse ppl, I've seen a few luxury cars with PS4ST. Probably as OEM tires. But you can't buy those at the Michelin shop.
