New Rubber Rcommends - ZR-1 Net Registry Forums

XfireZ51 · 11-12-2015

All,

When I originally bought my 92, I replaced rubber w OEM C6Z06 wheels with 18/19 Nitto Invos. Overall I have really liked them but it's now been nearly 5 years and the rears are showing their wear. Went with Pete to get some gyros and so I had him drive the car to try out my latest tune and listen to the Z06 flapper valves with switch in Open/Close positions. Well naturally Pete got "on it"
and he was able to "beat" the ASR getting the car going sideways when he mashed the go pedal. It happened in first or second. Overall, the motor is running great w the latest tune but the tires are not holding. So I'm thinking of some new rubber even tho the fronts are still in very good shape.
I started looking at Michelins. Got a recommendation for the Super Sports.
Currently have 325s in back, but the Z06 guys are putting 345s on the rear. That could require a move from 275 > 285s in front in order to keep ABS happy.

What say you ZR-1 brethren?

The Nitto Invo's hold pretty good. Better then the Mich's IMO. Invo's rubber is softer.
Remember the ground is getting cold & the Invo's are getting old.

#1 Summer tire, Michelin Pilot Super Sport.

I've had mine on for almost 3 years, 12k plus miles and a recent track event. I've got 70%+ tread left and tire performance is awesome!

I do agree that the Invo tire is great, but not sure if it is better
than the Michelin Pilot Super Sports.

Very true Frank. We were at the Crown Point Corvette Challenge a few weeks ago and watched a C6Z kiss both walls followed by a C7Z nearly do the same thing. That 1-2 shift is a bitch.
I think Al has Michelins. A few others do to.
I will say that the Invos held when I first got them. But I have made a number of mods since then going w Poly bushings all around. I'll be putting the DRM brackets on this winter. The Invos are a bit flabby for road course work. Dave J suggests the Michs' sharpen up the handling.

You can go borrow a set of Mich's from my car and see how you like them.

Frank,

Hi Dom!
I also have C6 Z06 calipers with 18" rims.
I use Michelin 335/30-18's PS (2) I believe.
They fit, I like them but:
1) EXPENSIVE
2) Not easy to find, especially with recent DOT
tire manufacture dates.
3) Patch isn't as nice as D3's were on 17" rims.
4) Did I mention that they are $$?
Good luck,
Ted

When I had the PS2's on my car, I couldn't break them loose. What a disappointment in my car. Then I mounted Eagle F1's. I can tear them off the car, even more disappointing.

Dom,
I'm running Michelin Pilot SS 285/18 fronts and 345/19 rears. The Pilot SS 345/19s are on the plus side compared to other 345/19 tires. In my case I had to trim the inner wheel well liner in a couple of places and machine off the head of forward lower trailing link pivot bolt to gain necessary clearance to prevent rubbing when going around corners and such. Also had to machine up 50 tooth reluctor wheels for the rear spindles to keep the ABS and ASR systems from freaking out. No qestion about Pilot SS excellent performance and ride quality.

I said same thing.

That was second gear at about 40MPH and breaking them loose like she was on ice.
Car runs good n strong.
