ZL1 PSS tire

[HRD_WRK]

Thank you sir for your comments below.

Thanks.
Happy 4th

Disclaimer: this car is a DD on the rough roads of NJ.

Rear 315/35/ZR20 K2 Ferrari.
Front 295/35ZR20 K1 Ferrari (101Y).

The 295 K1 Ferrari (105Y) are too wide.
Over summer mileage, the fender sliced into the edge of the tread.

However...on a track in PSM 5 may be smooth and stiff enough not to rub.
But they do stick out beyond the fender, if that offends tech inspectors.

I now have the 101Y and get only a slight bit of occasional rub.
Although others claim to not have this issue (DD in NJ again).

With a performance alignment I would expect no issue.
The 105Y may fit with sufficient -camber.

Thanks for the models and additional information.

Is your car lowered at all, or still stock height and suspension?
are you at stock camber? - I think it's -1.5.

Do you have any concerns with the lower SL rating on rhe 101Y?

[2014CamaroZL1]

Stock height and camber.
The OE front tires are 100Y.
The 101Y exceeds that, so all good.
The rear K2s have +3/32 tread depth, + 0.1 tread width, and + 1 pound compared to the K1s.
According to the Tire Rack.

Good point on the fronts - thanks.
My old paperwork frim tire rack says the tread width of rear K2 are 1.5" (13") wider than the K1 (11.5). Maybe it's wrong and have been fixed on the site.

Would you buy the same PS2 s again? Decent low temp grip in spring fall?

[2014CamaroZL1]

The TR website indicates 11.5 for the K1 & 11.6 for the K2 in 315/35/20.
The PSS is an excellent 3 season tire.
However, I just noticed that you said they are only for auto-x.
In that case, get a more focused streetable track tire.
Go as hardcore as you can.

Thanks again.
originally I was going to get 18 or 19" lightweight rims with Hoosier A6 slicks, but drag racing is the primary focus right now and the ZL1 rims were great price from a friend.
I need a minimum of 200 treadwear and the the PS2 offers better grip and sizes vs the crappier and narrower Pzero.

My bad on title - meant the Pilot Super Sport , not Sport PS2.
