What are the differences between the michelin primacy 3 and primacy 3st?

from my understanding they should be the same.some called primacy 3,some called primacy 3st.there was once the shop offer me primacy 3 tyre.the tyre shown to me is primacy 3st.
however there is difference between primacy 3st and primacy 3zp.both are different model.

I think it's just different names. Worldwide it's known as just Primacy 3 but in Asia market it's called 3ST, both replacing the outgoing Primacy HP. There's already the new Primacy 4 though.

Bro this might help

I was reading about the primacy 4 that i got interested to look into the primacy 3. Was actually wondering whether the price premium on pilot sport 4 is really worth it for daily driving.

Definitely am interested in the primacy 4, but only officially available january next year in europe....wonder how long will it take to reach our shores....

Will check it out, thanks!

I have experience with that.

My car had four primacy 3 tyres as oem from the factory. After I got a flat from puncturing one tyre (side wall), I got two rear tyres replaced with primacy 3 st.

My personal experience as a spirited driver, is that st loses grip a hair more than the original primacy 3. It's nothing major, but you can feel when cornering hard that the ST tyres have inconsistency a bit. The car feels like it may oversteer for a split second. When I tested rocking the car right and left, i can feel the back being a bit unsettled compared to when it was before. Did not lose control, but I didn't feel the confidence of the other that would maintain a curve at the edge.

In the straight and regular driving, it is the same comfort, so no issues there. Given the choice though, I would prefer the primacy 3 as it is a bit more sure footed overall.

There quite a big difference in price between primacy 3 and 3st if not mistaken.

You can take a look at Michelin Malaysia site and you’ll probably notice some of the 3 is rated MO (for Mercedes)/BMW, however the same size of the 3st variant isn’t and their load index is also not the same.
