Due to the lack of options for OE Z tire sizes I am considering running C6 GS/Z06 wheels I have left from C6 GS I traded in for the Z.
I am looking at P Zero DH 285/645/18 Front and 315/705/19 rear.
Last month my rear cup 2 delaminated so time to make a change.
Cup 2 $$ are prohibitive so looking at options.
Anyone with experience, your comments would be welcome.

Reason: Clarification
Some of us have been running the Pirelli P Zero Slicks on our Z06s. The ones closest to the correct tire diameters are 305/660/18 front and 315/680/18 rear. I use 18x11 wheels in the front and 18x12 in the rear. The 18s will fit over the ceramic brakes if you get the proper offset.
CCW C10 18x11s will fit in front and 18x12s will work in the rear. The CCW 18x11s will also work with Hoosier 315/30/18 and their 18x13s will work with Hoosier 345/35/18 tires in the rear but the rims are too wide for the Pirelli's.
A bit off topic since Pirellis are 18", but 19"x13" lets you clear the control arms, while keeping the benefits of using a 13"-wide wheel (stabilizes tread, increasing traction). Yes, scrubs are about half price shipped, but I also wonder if the price gap is really that high with R7s (or R888Rs, etc.). In my experience, new tires lasted significantly longer, and I didn't have the consistency issue, either (i.e. not all scrubs are in the same condition).
Compared to Cup2, though, yes, scrubs would always make sense since cup tires don't seem to last any longer (based on what I've read) than scrubs : )
FYI, trackdaytire.com has 8% discount + free shipping on Hoosiers, and SimpleTire.com has 15% discount + free shipping on Toyos. Finally, Discountedwheelwarehouse.com is the cheapest I found for Michelins.
Sorry, yes I meant UCA. I'm finding Pirelli scrubs to last me about the same as new Hoosiers and I've gotten them for as little as $100/tire plus shipping by the pallet.
Due to the lack of options for OE Z tire sizes I am considering running C6 GS/Z06 wheels I have mounted with 285/645/18 Front and 315/705/19 rear.
Yes, I have run those sizes. My wheels are 10.5" front and 12" rear. They worked fine. I have also run 305/660/18 on front. The rear is a little tall and rubs on the liner. The front rubs a little on the spat.
Here is a photo with the larger fronts mounted. https://cimg6.ibsrv.net/gimg/www.cor...b1277fc581.jpg

315/705/19 probably too tall? If my math is correct it’s 2” taller than OE, 305 probably better fit.

They are a little tall, but they work. Others are using them too, but if your using take-off slicks the 18" rears are a better fit or you can get new 19" R7's, etc.

Anyone running PZERO DH Slicks on C7 Z?
