New tires for 19" wheels?

[jerry33]

I'm almost at 19k and need new tires. The wheels slip are slipping when I accelerate hard.

Does anyone know anything about Michelin Pilot Sport A3 tires? My friend's brother is a Tesla service technician and told my friend that they were considered the "newer version" of the Primacy MXM4, but I got that 2nd hand so I'm not sure what he meant - if they're actually better than the Primacy or even appropriate for a Model S.

Here's Michelin's comparison page. The A/S 3 has longer life and better comfort at the cost of less fuel efficiency, handling, and braking.
