Sidewalls of this tires are not reinforced as much as other high performance street tires. Thats the reason they are a lot lighter than dunlop star specs for example. Iam not trying to scare you. Just my 2 cents
I can't disagree more. I have 4 track days on my PS2s and I have nearly 25,000 miles on them (the track days were at about 5k miles) on an E92 M3. As long as you don't over drive the car (unlikely as a beginner) or over drive the tires you will be fine. My 4 days include 3 days at Thunderbolt where I was one of the fastest cars in the advanced run group so I wasn't going slow. .
Keep an eye on your sidewalls and increase the pressures a few pounds if you are getting wear past the triangles on the sidewall. You'll be fine on the PS2s.
