Tires last 9000 miles

[KC Z28]

I have my original set of tires on and they started getting quite dangerous at 9400 miles I unfortunately did not get any track time but have a blast with the carthis was without any tire rotation front and rears need replaced

Are these Z/28 tires? If so, it's normal; actually sounds above average.

3200 miles, including 4 track days, down to 2/32. Maybe another 1000 (dry) street miles on them left. Wearing better than I anticipated as well.

If I may ask, what cold/hot pressures did you use? And how much camber did you have front and back?

OE/owners manual recommended pressures and track alignment specs. Max I could get was -1.9/2.0 on front and I think -1.6-1.8 on the rears. I'd put more camber in the fronts if I could, maybe 2.3-2.5, but it's not there to get with OE parts.

Tread face wear looks amazing even. Shockingly so to my eyes. That is what a well engineered suspension gets you

Sounds great! I could not get more than -1 at the rears, so I had to keep fronts at -1.8 to keep the balance. I'll replace the rear camber bolts with aftermarket ones. If I can get to -1.5 at the rears, I'll shoot for -2.5 at the fronts. I don't wanna waste my Trofeo Rs with very low camber, but your experience is very promising!

The manual states no less than 26PSI, yet Pirelli site states 2bar (29 PSI) hot, which would require 22-23 PSI cold. I just don't think 22-23PSI is acceptable, so I'll follow GM's recommendation of 26 PSI minimum. An alternative way would be starting 26 PSI cold, then keep bleeding until 29 PSI hot, but who has time for that?

G:2s last quite long (15K?) in our experience, until you go to track with them.
