Does anyone know if these are the same as the Primacy 4 Plus? If not what’s the difference?
December 26, 2023
The ST version is only available in certain markets and is not the same as the Primacy 4+. I'm not entirely sure what the differences are but I believe the Primacy 4+ is the "better" tire.

Practically, the best touring tires for Asean climate. I have tried:
Toyo CR1
Toyo Nanoenergy 3
Goodyear Assurance Triplemax 2
Hankook Kynergy Ex
Dunlop SP Sport J5
Continental CC6
Viking Protech 5

The Michelin Primacy 4 ST (ST denotes for Asean market, as I understand it) is the most durable, grippiest & comfiest among all those. The quietest was the Continental CC6 but Michelin wasn't far off. The most fuel-efficient was the Hankook Kinergy Ex but again, Michelin wasn't far off. Overall, Michelin is the top dog of the list. Downside, you ask? Well, there's one. Price. It was also the priciest of the bunch. Lol. Still, worth the money if you can afford it.
