I went in for an oil change today and they measured my tires. I was wondering what do they measure stock. Mine read 8/32 up front and 9/32 in the back. I wanna get an idea on how long these are gonna last. So far I only have about 15,000 KM on them.

Oh ya that is on an 05 SS/SC if that matters.

 

I believe 10/32 is new for these tires, so you're doing good! Treat them well and you should be able to top 50k, maybe 60k km, which is great for these tires.
