Time for me to replace the original equipment Goodyear rear tires on my 2008 Z06. Has anyone had any experience using the new Eagle F1 Supercar G:2 ROF tire? Looking for input on traction, noise level and wear. thanks in advance for the input.

Get Michelins instead. GYs are crap. The OEMs I had only lasted 9300 miles of easy driving.

The 07 Z's did not come with the G2's the OP was asking about.

The OE GY F1Supercar G:2 RFs are nearly universally panned by the owners who have them on their cars. They came standard on my '13 GS with the M6 + F55 option and I can say that, altho I've only put about 3500 miles on 'em, they seem like they are noisy, stiff and suffer more than typical from tramlining on uneven pavement. They obviously have a very soft tread compound, so you might be inclined to try them if your main plan is track use, but I presume there are other--and better--tires for that purpose. Tread life is approx 10K +/- 5K based on anecdotal reports from other CF posters, presumably as a result of a 220 UTQG and a new tread depth of 8/32" vs the usual 10/32".

One of the biggest hits to the tire is it's performance in both wet and cool-to-cold temps. Never heard or read anyone who didn't soundly criticize it's overall performance in less-than-ideal conditions. The reviews that were complementary were all about warm-weather performance, ESPECIALLY once the tire was heated up for track use. Bottom line, if you want max performance in warm-hot conditions for high-performance street or occasional track use and don't mind the trade-offs of poor tread wear, harsh ride and noise, go for it. Tire Rack/Goodyear is offering an $80 rebate for a 4-tire purchase right now.

Many of us have found the Bridgestone RE0505A run flat to be an excellent choice for the Z06. Won't turn it into a Lexus, but is an all around improvement. I have ~15,000 miles on mine and have around 7/32" of tread left(they start out at 10/32" where the Goodyears start out at 8/32").

A friend also has the Bridgestones on his Z06 with 30,000 miles on them and around 3/32" left. He plans on getting new Bridgestones at 40,000 miles on his present set.

Since you are asking about the G2s, I'll respond since I have them. When they are cold they are somewhat slippery when you get hard on the throttle. There's a decent amount of noise on coarse pavement, but little on smooth roads. I can't advise as to wear, since the previous owner replaced them sometime in 2012 and they still have 5/32" left. I haven't tracked them myself, but have confidence they perform well when warmed up. Other than that, I can't add anymore than what icntdrv55 posted.

Michy PS2's and be done with it. 285/345.

He will have a slight problem finding those sizes in run flats.

My original Goodyears have run 10,700 miles.
The front tread reading on both front tires at each rib is 5/32 out of the original 8/32.
Reading from the inside to the outside of each of the rear tires I get the following tread depths:
Left rear: 4/32, 4/32, 4/32, 4/32, 3/32. Camber setting is -0.1.
Right rear: 3/32, 3/32, 3/332/3/32, 2/32. Camber setting is -0.2.
I am replacing the rear tires at this time only because of the wear on the outside of each tire which is indicative of positive camber but my rears both have slight negative cambers. When new tires are installed I plan on increasing the negative camber slightly to compensate for the outside tire wear. My biggest complaint with the original Goodyears is the noise and would like to reduce the noise level with the new set of tires.

Thanks for the response. Will research the Bridgestones that you have recommended.

AzDave47

That camber alignment is way less than factory or any street setting I have ever seen recommended. I think -0.7 is the least front camber recommended. It is interesting that some alignment shop went with those numbers.

JoesC5

I believe the camber settings he posted is for his rear tires, not the front's. But, even for the rear, that's not much camber. I run -.6 on my Z06 on the rears, which works very well with the -.9 camber I run on the front.

Yes, I missed that. It would still be too little for HPDE's, but good for street tire wear if not cornered hard and good for straight line work.

Why would anyone want a Z06 over a standard Corvette if they want a better ride. Maybe some get the 6 for looks only?

JoesC5

Not all Z06 owners have one brother in law that's a chiropractor and other that is a dentist.

I have a Z06 but I do like to get in it and drive on a 3,400 mile 11 day cruise. This summer, I will probably do over 6,000 miles on a 2-3 week cruise followed in a couple of weeks by a 2,200 mile cruise for 9 days, followed in the fall by another 2,200 mile cruise for 7 days . For that, I like reasonable comfort and good fuel economy(28-29 on the Interstates).

And then drive it on some mighty tight curves in the Ozarks on a 250 mile cruise on a Saturday for lunch or cruise to Alabama and drive 160+ on the high banked Talladega track.

And not every Z06 owner is a youngster. My tired old 71 YO body thanks me for giving it some comforts in life.

The Z06 isn't just made for the track. If fact it makes an excellent street cruiser.

Good post Joe. I was making a point in general addressing concerns about noise and ride quality. The Z06 was in fact designed for guys who may want to track their cars, mainly on road courses, and set the car up to be a decent compromise between street and track. That's why they did development work at Nurburgring, and just not on the GM test track.

For guys who will probably never see a track in their own car, but still want more cornering and braking power, then the standard Vette with the Z51 package would be ideal. For the masses, the standard equipped Vette with better sound proofing and ride quality would be ticket, while still looking cool.

Jose, based on the alignment spec research I have done it appears that the -.6 rear camber and the -.9 front camber settings on your Z06 are the recommended "max" Pfadt Street Specs.

When I purchased my new Z06 the Chevrolet alignment mechanic changed my front camber settings from the factory setting of -1.3 (right wheel) and the factory setting of -1.0 (left wheel) to 0.0 on both front wheels. The rear camber settings where changed from the factory settings of -1.1 (right wheel) to -0.2 and -1.3 (left wheel) to -0.1. We decided on these camber settings because I told the mechanic I was not going to drive the car aggressively which is how the car's factory alignment specs are set up from the factory.

As stated in my earlier comment, both front tires show even wear at 10,700 miles with 5/32 across the entire tread width and no sacrifice to my driving style handling. Will most likely leave the fronts set at 0.0 camber when I replace the rear tires.

How many miles do you have on your ZO6's rears that are set at the -.6 camber? How is the rear tire wear from the inside of the tire to the outside of the tire?

I was thinking of setting the rear tire camber at -0.5 when new rear tires are installed and the car aligned. Hopefully the -0.5 camber setting will eliminate the excessive outside wear of the rear tires that I am currently experiencing.

Appreciate your input.
