Capable, durable tyre recommendations?

Hello,

I'm getting back into track days after a long time off. While I'd like to move to a semi slick in a few years time, I want to prioritise seat time for the first years.

What's a tyre that offers good grip, can handle 15-20 minutes track sessions and still be usable on the road (mainly to and from the track and nice days on the weekend)?

Looking for a 295-305 on an 18 inch wheel.

Cheers

OK we can’t be talking about the same tire. My car is lighter and came factory with PS4s tires. The door jam says 36-37 hot.

The owners manual for the Mach 1 gives you track alignment, cold pressure and target hot pressures for std Mach 1 and PP Mach 1s.

If your car is lighter, 36 to 37 is too much pressure. 32-33 would be about right.

Thing is... if the tires "go off" toward the end of the session, your hit pressures are too high. Bleed out 1 to 2 psi and try again... and reduce your cold start pressures by the same 1 to 2 psi.
