Hi,
I sold my 2002 Z06 back in 2019.
A friend of mine has a 2003 that needs new tires.
He has the original Speedline factory stock rims on his car.
Seems like there are even fewer options available now than there were a couple of years ago.
What sizes and/or brands are you C5 Z06 owners on stock rims using?
Thanks,
Silverbird

There aren't really any stock-size tires available (assuming matching front + rear). These are some options:

• 275/40/17 F & 295/35/18 R (probably the most popular combo. Available with Continental ExtremeContact Sport 02: front on Tire Rack , rear on Tire Rack)
• 255/40/17 F & 295/35/18 R (best option here is probably Continental ExtremeContact Sport 02)
• 255/40/17 F & 285/35/18 R (I ran this combo for a while, plenty of choices)

Another possibility is changing the aspect ratio, which means a decently taller tire, but it will still work out just fine. Going with a Nitto NT555 G2 tire, could do 255/45/17 F & 295/40/18 R.

Thanks for your help.
I'll forward the info that you provided to my friend.
