I'm curious if anyone is running Hoosier R6/A6 in 315/30ZR18 on the front of a C6 Z06 on factory rims. I know they have 295/30ZR18 and can use them if not able to go with the 315's.

I plan on running them at the track aggressively and want to make sure I don't have any issues. I can run 315's on my set of Forgelines on the front with no issues but that is on a wider rim.

Does anyone know of someone running 315's in the front that also has after-market brake duct hoses?? Any issues??

10 1/2" rim? Same as C5Z rear? I've fit them on before.

I have a couple of scrubs in that size. You can mount them, use them, or whatever you would like.

Nope, the stock C6Z fronts are 9.5". Hoosier recommends a wheel width +/- .5" in comparison to the affective tread width (315mm = 12.4"). With a 315, I wouldn't go any smaller than a 10.5" wheel; I'm running the 315 on an 11" front wheel.

Eric my friend runs 315 all the time on the front of his z06 no issues
but he is using ccw 18x11 rims

you coming to track attack at all?

one guy has his spot for sale for $800 i think

yeah that's a lot of tire for a 9.5" wheel.

275 ho-ho fits about perfect on a 9.5" wheel

Randy - I'll be up tomorrow or Thursday to get my car. We can talk then.

That is kind of what I was thinking.

I run 315's up front on 18X11 rims and have had no issues. I picked up a set of OEM comp greys and was going to use them to keep an extra set of track tires on hand and wanted to run a 315 up front. Doesn't look like it will work very well - I'll just have to run 295's on the front with the stock rims.

Still not sure on Track Attack.

The following rim widths are the general guidlines that OEMs use for tire sizes:

Tire ---Rim

275 = 9.5"

285 = 10.0"

295 = 10.5"

305 = 11.0"

315 = 11.5"

325 = 12.0"

335 = 12.5"

345 = 13.0"

I run 315 Hoosier A6's mounted on OEM rear C5Z wheels on the front of my C5Z without any issues.

after you cross 275 you will get bad inner wheel rub on wheel lock if you have brake ducts in the front. FYI. make sure you get advice form people running ducts on wheel set up prior to making this decision.

Good point.

Does anyone know of someone running 315's in the front that also has after-market brake duct hoses??

Use stock sizes and keep an eye on tire pressures.

I autox on 315's up front on the base C6 18x8.5 wheels.

no extra brake ducting here though
