These Are 10.5's right? (please look)

275/35/18's Im 95% sure they are 10.5's. Do you measure from the inside of the lips, or the outside for width. They dont even make a 18x10 Z06 replica do they?

I am asking because I am thinking of going 295/35/18's in the back, and eventually maybe all around. I know they will fit on a 10" or a 10.5" rim, but will I have rubbing issues on the front spindle with the 295's? I guess if I get them for the rear, I could put em on front and see. But I would like to be able to rotate them in the future. Thanks for your help!

those look too skinny for 10.5... i think they are tops 9 wide.
I have 18x10.5 on all 4 corners... check signature for some pix... and running 315s on all 4... no rubbing issues whatsoever.
C6 Z06 are offered in 18x10.5 just like mine but the z06 design
rim width is measured from the inside, where the tire will bead.

I am pretty sure those aren't 10.5 wheels.

Here is a picture of my 10.5 C5Z wheels:

this is what 18x10.5 will look like in the front:

and these... same width... with wheels turned out:

I'm agreeing with the above statements; those look to be 9.0-9.5, only one way to be sure though...

thanks guys they must be 9.5"s then, I dont think they are made in 18x9's. So if they are 9.5, do you think I will have any issues mounting 295/35/18's?

look on the inside of hte rim... most rims will have the size printed on the inside.

although i am betting on 9.5

they were 9.5s, but they are on and they look and grip awesome, had to roll the fender just slightly.

Just curious if anyone has any insight to what specs the wheels for the car on top have. Or Eugenio I think u said yours are the same. Just wondering, mainly the rears because I only want 9 or 9.5 fr.

both those pics are of my car... lol
the top is 18x10.5 C6 wheels on all 4 w/ 315/30-18 on all corners.
the bottom is 17x11 ZR1 wheels on all 4 w/ 315/35-17 on all corners.

Then I got a few things for you.
1. Your car looks sick. I knew the bottom was you, but I didn't realize you had a vert.
2. Did you use spacers for the C6 wheels?

and last, did you have to roll your fenders. I think that looks so sick

1. Thx... I like them topless
2. FRONT: Since I use the Porsche big brakes in the front, the disk-location relative to the hub is different than stock... it's the equivalent of a car w/ stock brakes and a 1/2" spacer... but since i have the Porsche brakes, i use no spacers.
REAR: I use a 1/4" spacer

note: this is for the C6 18x10.5 wheels... same goes for C6-Z06 wheels.

My reasoning for fitment was based on the fitment of the 17x11 +50mm allround.
w/ ZR1: front = 1/4" spacer, rear = no spacer.
going to C6, although wheel is slightly narrower by 0.5"), offset is based on the centerline... so I wanted the centerline in the same location... which would give me 1/8" extra clearance on the inside + outside. = safe enough.

So because the offset is ~ 1/4" more on the C6 (+56mm) vs ZR1(+50mm), added 1/4" spacer compared to ZR1.
making C6: front = 1/2" spacer, rear = 1/4" spacer.

Because I'm the "Crazy Canuck" and have huge Porsche brakes, those already offset the rotors hat by 1/2", making the no need for a spacer for me in the front.

Hope this helps.
