I'm also a Grandpa. I just got back from running my Vette in the Big Bend Open Road Race. 120 miles of closed two lane highway at 150+ mph. I have Michelin PS ZP tires and they're awesome. The GY tires were junk. Wife's Shelby GT500 had the same GY's. They were useless by the time the car had 10k miles and she doesn't drive it hard or race it. Those are some of the worst tires ever made IMO, and I've owned a whole lot of cars and tires over many years.

Yo billy you are one funny dude. I like your style because I agree with it. I cruise just like you. You know how many people get along side of me and yell stuff like "lets see some rubber" or c'mon get on that baby. I know what the car can do and I got nothing to prove. It pisses them off even more when you just drive away with a smile from ear to ear.

Think about this C6's have used GY's. What is the standard tire for the C7, you guessed it!

Put on a blindfold to pick an alternate replacement and you will win . . . .

I cringe every time I see someone doing burnouts with any car. The cost of these tires is so high that I could never afford ruining a set just to show off. You can do burnouts in almost any car, so it certainly is not a measure of the cars power.

Now, I can drive a road course or drag strip as well as 90% of those on this forum (yes, I'm a grandpa too), but you won't see me doing so with my expensive tires, at least not at the drag strip. I have a set of MT Street ETs for the strip and using up a set of GY tires on a road course would be worth it. The GYs are just fine for my street use.

I got 14500 out of my goodyears on 2012 z06 they had a few more thousand in them. I switched to mich noise level is okay I just can't seem to tell all that much diff lost part of hearing in Marines. Hope mich for 2400 last longer than 14500 if not it will be bridgstones another brand that everyone talks about being good and cheaper. Gee theirs a lot of use grandfathers on this post wonder how many of the younger set can keep up at a safe legal site just sayin.

Well, my question was which you have, as I said, there are 2 different tires on the Grand Sports by Goodyear. Is your car a manual transmission and do you have F55?

The Gen 1 Supercar EMT isn't that bad of a tire. They are sensitive to toe in settings so you need to make sure their isn't too much rear toe in or the outside of the tire will wear quickly. Most Zs and GSs that I have seen with worn rear tires have worn them on the outside. They do ride harder than a non run flat tire but that can be said of any run flat. Where they excel is on the track. A well worn EMT (3/32 or less of tread) will grip like mad in corners when it gets up to temperature. The first 10 track days I put on my Z I used a set of well used EMTs that I purchased with a set of wheels. They worked great and were better than the new NT05s I replaced them with. Currently I have a set of new Michelin PS2 ZPs on the car. They ride a little less stiffly than the EMTs and will probably will have more longevity since they come with more tread depth when new. From a wet standpoint the new Michelins and a set of new EMTs seemed to handle deep water on the highway about equally well and I didn't get any hydroplaning from either set. Of course I was only driving 75 in the rain so they might not be as good at 80 or 85.

I have an A6 as well but I've tried the launch control at a driving school using the ZR1. It actually preserves rubber. Think of it like an anti-lock braking system only in reverse. Here's one description (btw, really good drivers are able to beat it): "the launch control feature (manual transmission only) automatically modulates engine torque for the best-possible acceleration without excessive wheel spin. When the driver pushes the throttle to the floor, the system holds a predetermined engine speed until the driver releases the clutch. Then, the system modulates engine torque 1,000 times per second to maximize the available traction.. "

Not sure why GM selected GY as the oem tire for the C6 but I do know that, after having been around for a few years, it's not the case that other auto manufacturers are clamoring for either the GY EMTs or Gen 2s. To this day, GY only offers the EMTs in sizes that fit the Corvette base, GS and Z06 while the Gen 2s are only offered in sizes that fit the GS and Z06. Meanwhile, as MKen points out, GM could have continued using the GY EMTs on the C7 but has chosen not to. That says something to me.

Completely agree... Ride rough, wear fast, and are noisy!

truckplay

you are the exception. for one, I considered the GY tires dangerous. My coupe came with supercars, they lasted 7k and were only acceptable for 2k. I was given a set of GSd2 (I work for GY) and those were even worse, had NO TRACTION at all, I hated them so much I did burn outs until they blew up after I could not find anyone who wanted to take them FOR FREE. I replaced them with Bridgestone RE11 and the level of traction was night and day. I really don't care how long my tires last, I only drive the car about 5-7k a year and I do BEAT on it pretty hard.

Don-Vette

IMO the GY are a good tire but they wear out too fast. I'' be going with the Bridgestone RF when it's time,much mo' cheaper.

REDC4CORVETTE

Oh come on guys the GY's are great tires, they are run flats so I ran mine flat at 14k and never looked back.Noisey unstable squeel around corners .I got the top of the line radio from gm in my vett and those tires made me think a cop was behind me from time to time.
I have my Michelins and price doesn't bother me but stick your finger nail into the tire and it is soft but I like the slience
Rides great and when I get to the track they win trophys and pay checks for me Michelins all the way


I think this is what happends to good years if run them to long on your car .

Because of the sucky tire wear, the sucky grip, the sucky noise and just the overall suck rating of these expensive suck tires.


Did I mention how much I think GY suck ?

SSWEET

Dumped the GY's on my GS at 9000K....3/32's on the back, a little over 4/32's on the front....went with the Bridgestone RFT's....

This is why you don't have a problem with factory rubber

Mac-427

if you had 75% tread left after 17k miles, then they are just fine for your driving style gramps!

Remarks like the above are a sure sign of a person lacking in maturity and judgement. Hardly the attitude necessary for driving high performance cars on the street.

red2012

Yes manual trans and no F55.
