Hi guys,

I'm looking at new tires for the Z this winter, and I've heard that our rear Z06 rims can accommodate wider tires than the 295's they come with.

First question is, would a 315 fit? Say, the 315/30-18 Falken Azenzi RT-615? Any issues I should be aware of? Anyone have pictures of a 315-anything on a stock Z06 rim?

Next, if these tires will work for the rear, I would need 275/40-17s up front as Falken doesn't make this tire in the 265/40 size. I currently have 275/40's up front on my current tires, with 295/35 in the rear and they work well together. Would 275/40 and 315/30 go along with each other? I've heard that certain size differences can cause trouble for the Traction Control / Active Handling systems.

Does anyone have these tires? Are you happy with them? Any pictures?

Lastly... can anyone recommend a place to purchase these (besides Discount Tire)? Tire Rack doesn't carry them and I know of no other online tire stores; I dont want to order from Discount Tire because their shipping charges to Alaska are disgusting. (More than TWICE what Tire Rack charges for Alaska shipping). I wish T.R. sold Falkens.

They fit, go for it:





I was also running 275/40/17 up front, no problem at all with the traction control.

Wow, thanks for the pics! Those look great. That's exactly what I want... a nice, "square" shouldered sidewall. I have never liked that the 295's look stretched on these rims. Do you have a pic from the side? I'd like to see how the 275's look in terms of sidewall height, compared to those rears.

what tires are those in the pics?

I had the exact sized Rt-615s on my prior C5Z...they were awesome. I believe the gentleman who purchased the car from me...two years ago...finally wore them out. They are great tires - not expensive for the performance, and they perform very well.
Go for it, you'll be very happy.

The sidewall differences look funny, you will want a 35 series up front, I know I did. Here are side pics:

those tires above remind me of advan neova's but i don't think they are? i can't place it

also, the kumho XS is out in 315 30 18 and 275 40 17 and is a faster tire than the falken 615. it also doesn't grease on the track like the 615 did.

Excatly what i have on my car. It does look a little funny with the front sidewall being a little bigger but most people dont notice.

Did you read any part of the thread?

Tires in pics are not the 615's. I have the exact tire and size on my Fikse, tread is much different

Yes, he read the thread

they are Hankook R-s2

My fault. At first glance they looked like the 615's.

Thanks for those sideview pics. I guess I'm quick to spot the sidewall differences only because I have the 40 series up front currently, and so I've had a few years to become aware of it.

If, instead of going with 275/40 up front, I went with 255's instead... would that be a huge sin? I know the stock was 265; so I'm still pretty close to that. Would there be any drawbacks to going slightly narrower in front?

SteveDoten

hah, that is what I have up front
