Default Are the hoosier r6/a6 only choice tire for oem c6zo6 wheels??

I cant find a track rear tire to fit the 19x12 rims. Iam trying to avoid getting a set of 18 all around (CCW) $$.
Thanks.

Toyo makes a couple of Proxes R888 tires in the 20" size.

Didn't someone recently post about a Pirelli Corsa or something that was faster than the Pilot Cup sports but not quite to the hoosiers for speed but close? (on the stock z rims) -Dan

Toyo and Pirelli do not come in stock sizes for C6Z06 oem wheels unless someone can suggest a different size tire for stock wheels. I'd love to know myself.

I was in the same situation, ended up going with CCW's 18" all around on the Z. Better selection of tires and their costs were the deciding factor.

Keep an eye the forum I bought mine used from a forum member.

Why wouldn't you use the A6 or R6 345/30-19 on your rear rims (or is the 345 too big for the rear fender wells on a Z?)? I don't think it is too big because I could swear a friend of mine runs them on his Z. I currently use the 345 on a 19 X 12 rim on my car, and love them.

The only faster track tire than the A6 would be a Michelin racing slick (not Pilot Sport Cups).

what's the need or advantage for a true racing slick over the DOT R6 track tire?

All the other R tires with tread are far more expensive than Hoosier and grip significantly less, so there is no reason to use them (unless you HAVE to drive to the track with your tires).

A recent alternative is the Kumho V710 which is now available in C6Z sizes, but the Hoosier is still the best grip and most economical choice (if one can use that word for C6Z tires).

I agree. Unless one specifically goes with Michelin racing slicks (or possibly Pirelli racing slicks) there is no other choice but the A6/R6.

My experience with the R6 indicates it is not as good of a tire as the Kumho V710. The A6 may be faster but I had trouble finding any way to get the R6 to perform and never was able to run as fast on new R6s as I did on worn out 710s. I used to buy used 710s with 3 heat cycles on them and get close to a seasons worth of HPDEs and autocrossing out of a set.

I just got off the phone with tire rack they stated that the kumho v710 are not available in stock c6z06 sizes. What size can you run with stock wheels. Also spoke with the rep at Kumho who stated that the tires aren't available in stock C6Z06 sizes and won't be for 2010. The only close match is a 285-30-18 front and a 335-30-19 rear. How would this match affect the cars engine drag, TC etc... Tire rack has the kumhos for about the same price as the hoosiers so why bother unless the kumhos are better than the hoosiers.

Do yourself a favor and NEVER call and listen to advice from a $12/hour operator at Tire Rack about tires for your C6Z06.

Those sizes will work perfectly on a C6Z. No one runs OEM sizes on C6Z's with Hoosiers anyway. Most run 295 and 345. I personally run 285 and 345. I measured the actual sizes of those tires, as I was going to buy a set last season to try them out, they will work.

The original poster asked if there were alternatives and I responded that there were. Now if they are better/worse that is a different thread.

You can find both tires cheaper elsewhere. The 710's are a good tire for sure as are the R6.

I read your thread HOOSIER VS KUMHO DISCUSSION
I also read the part when you spoke with the REP from Hoosier. Hope he makes more than the 12 dollars an hour that my REP makes. Any way, I totally understand the points that you bring up. I also understand the points that Frank Gonzales makes. But I should have been clearer. The original post asks about availability for stock wheels so what are the sizes that can be run using stock wheels. I take it that your running 285 30 18 front and 335 30 19 rear for Kumho. You've stated on other posts that Kumho is now offered in C6Z06 sizes, how is this true?

I think we are miscommunicating. First, I spoke directly with a Hoosier engineer, also Tire rack is not going to deviate from the OEM sizes when it comes to availability for a tire. This basially limits lots of choices.

From my experience you can run either 285 or 295 on the OEM front Z06 wheel. You can also run anything from a 325-345 on the OEM rear wheel. When I state they offer a tire in C6Z sizes, I specifically mean they offer a tire that falls into a range that will fit on the OEM wheel, not that it is the same exact size as the OEM rim. If we C6Z owners stuck to exact OEM sizes, we would have little to no choices in both street and race tires.

Also, tire manufacturer tire ratings 285, 325, 345 are not hard industry standards, if a tire gets a 285 rating, it simply means the actual tire measurements fall into a specific range that meets the requirements fall into that category. There are manufactuers who 285 is wider than a 295, so you can't go just by the general tire rating. Looking up detailed measurements is more precise. This is why I run 285 R6's in the front instead of 295's, the 285 has a slightly wider tread width, and is lower in profile even though it gets the smaller rating than it's big brother 295.

The 335 Kumho has a tread width of 12.8" vs the 345 R6 has a 13". So you get a bit more meat with the Hoosier. What's even more interesting is the Hoosiers are a little lighter, so in my opinion that makes them the winner (for now).

No fights bro, just wanting to help out, hopefully I have
