2014 1Le Tire Swap?!

[EarlyApex]

I have both, I use the GY for track days and the PSS for the street. If a track day was going to be wet or a chance of wet I use the PSS's. They start to fade after about 10 minutes of dry track where the GY's seem to stay good for the whole 20 minutes.

Try putting down a 1:22 with MPSS LOL

I am convinced all this crying about the Goodyears is just people who don't know how to drive a car like ours blaming their lack of skills on the tires.

Edit: This of course is not aimed at those who need a better all season tire due to the driving conditions they face.

Now if you are tracking the car all the time the GY are probably what to stay with, but many Auto X 1LE guys love the MPSS also.

Great post. The Goodyears are great when warm and great when warm on a road track. That is why they are the 1LE tire.

They are awful at the drag strip warm or cold.

They are very poor drivers when cold. The cracking is not the big problem, its the lack of traction even in cool weather. And if you even mildy modify your 1LE LS3 you will want to keep your car in the garage once the temps get below 50 degrees F when on the Goodyears.

I enjoy spirited driving, nothing crazy, and I just cannot trust the Goodyears unless the weather is very warm. Less fun for me. I still have not worn out the Goodyears with my garage queen. Once I do I will switch.

There's nothing particularly wrong with my Michelin tires, but in AZ I liked my Goodyears better. I also like how they look better, as well.

I had both and here are my comparison notes:

Like everyone else has stated, The Goodyear F1 G2 supercar tires are a warm weather tire. Anything below about 53 degrees and they start loosing traction and full throttle starts WILL result in wheels spin at just about any temp unless you are someone who feathers the clutch (which is bad to do in our cars). See the clutch issue threads.
They work fine in mild to moderate rain. Anything more than that and with any tire you must be careful.

Now, on a race course or auto-x, I give the Goodyears the nod. They are extremely grippy, almost race tire grippy. The PSS also do very well o nthe track, but I could tell the initial turn-in and bite when braking suffered "just a tad" with the PSS (But they are still very close in cornering grip capabilities) and are still very good performance tires.

The PSS tires are a MUCH better street tire and overall tire in my opinion and will last 2-3x as long, so they are worth the price.

There you go. :-)

Indeed, PSS tires are good at the track... for 3 laps! In my experience, they have quickly overheated, and by the time I started the 4th lap, there was not even much squeak left; it was all about greasy tires swinging around enjoying the day out : )

More on my experience below. FYI, I improved my time by 4 seconds when I borrowed my brother's wheels/tires (he also has a 1LE) with G:2s.

This isn't a drag car mi amigos. The Goodyears have completely the wrong construction and design to be good at the strip on a 100 degree day, much less a 50 degree day. I also do not understand the "wheel spin at just about any temp unless you are someone who feathers the clutch" comment.

Are you also talking about launching the car in a straight line? Why would anyone; ever; slip the clutch while under way? I drove my 1LE to work yesterday, it was 21 degrees out when I left home. By the time I got on the highway (1.5 miles or so up the road), my air pressure had increased by 2 PSI in all tires (which means the tires were generating heat and warming themselves up), and after 5 minutes of 60mph highway driving, the tires were up an additional 3 PSI and stayed there for the remainder of my commute. I had plenty of traction once the tires were up to temp, enough to have fun in the twisties at the end of my morning commute.

This is a track-oriented street car. Track, not strip. It makes many compromises as a street vehicle and doesn't even pretend to be a strip vehicle. Why do people keep referring to the OEM Goodyear's abilities to launch the car from a stop as relevant in any way whatsoever?

Not trying to offend, but I also don't understand this comment. I never had any issues, and I'm pretty sure I was using the clutch as intended. It's not like you can or are going to do a launch when you're 5th in line at a stoplight.

Living in the south, I do not have to deal with the cold that you do, but agree with everything you said. I let my clutch out the same cold or hot, and yes, do some feathering that will not hurt the car at all. Not excessive slipping, but feathering. And if you are not popping (or side stepping the clutch), every takeoff has an amount of feathering to it, and IT WILL NOT HURT YOUR CAR. Once under way if it is colder, I prevent the tires from slipping when they are not warm by not mashing the throttle. Does one have to drive a 400 plus hp car with track oriented tires different than a Cruze in the cold, yes, but one has to drive it different in the warm as well. I will stick with the GY's because I spent $3500 extra dollars on a car to get great handling and I want every bit of its ability whenever I want it.

My experience is trying to launch the car from a start with half throttle or more on the Goodyears will give you wheel spin. Maybe I'm the only one who understands that. I'm not talking about on the drag strip or with a car in front of you at a stop light.

Mark, how much pressure are you running when trying to do this? And what are you defining as 1/2 throttle? I am saying you can aggressively release the clutch and then go to WOT with little to no wheel spin on the warmed up GY's. This can be done at between 3 - 4K RPM. I believe the launch control is at about 4K (though I have never used it). Keep in mind, and this comes from my drag racing days with the '69, wheel spin of around 1 1/2 turns will give you your fastest acceleration. It is uncontrolled wheel spin that slows you down. You probably already know all this.

32PSI cold pressure. Half way down on the pedal just after I would release the clutch, it was easy for me to get wheel spin with the GY tires. Not so with the PSS tires. I agree that an aggressive release will not give much if any wheel spin, depending on how it's done, even with WOT once moving. Maybe I just have a car that has more low end torque. Who knows since I've never had it dynoed...I'm just sharing my experience. Please be careful out there and drive safely.
