Nitto 555r2 or GYSC3
 

Finally got a new set of Velgen 20x10/20x11 wheels.

Going to install the GM lowering/handling kit over the winter. Debating on tires...

I’m going to run 1LE sizes 285/30 & 305/30.

It’s either:

1) GYSC3 front/rear.

2). Nitto 555G2 front/555R2 rear.

I do not track the car, but spirited driving yes. I might give it a shot but it’s not in the plans at least next year. SC3 are awesome for that.

I’m interested in the new 555R2 as well, obviously hooking up should be much better then the SC3... but I’m curious to see how they handle. If the handling is good and they hook maybe it’s the best of both worlds?

Anybody with experience with the “new” 555r2 yet? The “old” 555r2 were actually marketed for handling, so I’m curious how these turn out.

If you aren't going to track the car, then neither of these tires is a good choice. If you insist on only considering these two tires, then the Nitto is a drag radial and only UTQG 100, so it isn't going to last much time at all and who knows how it handles? Their NT01 is the one they make for handling, but I don't think it's a very fast tire. The 555 G2 is their street tire, and it's not good at all. So of the two, the GY is by far the better bet.

But I'd suggest looking at the Continental ExtremeContact Sport or the Michelin Pilot Sport 4S for your use. These are both much better street tires: they will last a lot longer, they are quieter, they are much better in the rain. And they are both within about 1 second of the GY on a typical autocross course. The only thing they aren't good for is driving in below-freezing temps. I'm assuming that's not an issue for you since you were asking about the GYs and Nittos.

Neither tire is one I would want. I went with Indy 500 Firestones, love them.

If you're going to drag race at the strip you'll need a good drag radial like Nitto or MT, etc. but that drag radial will not work well in the wet on the street. My car came with the GY3R which is IMHO unsafe on the street.

If you're not going to drag race at the strip, but might roll race, and want the best tire for dry and wet but not ice/snow and not freezing temps, then the MPS4S is the tire.

If you're thinking of also maybe going to the road course once or twice a year in wet or dry, the MPS4S is definitely the tire. It simply has no equal.

If you're thinking of also maybe going to the road course once or twice a year ONLY in dry, the GY3R is a great tire and faster than the 4S.

I probably have more power than most and run the 4S 305/325ZR3019. I might do a drag roll race at Bandimere and I might go the High Plains road course a few times a year in dry or wet, but I am otherwise a dry and wet street car guy.

So, you have to "spec" your own tire to your car and unique situation.

I am pretty sure that every post above mine has not run the 555r2. It's actually a very streetable tire, that handles good, has great traction, and will last 10-15k miles depending on how hard you are on them. They have more tread depth then the original 555r that I ran prior and I still got 7k miles out of them with lots of dig runs. I currently run the 555g2 front/555r2 rear and it's a great combination. I don't road course my car but I haven't had any issue taking corners at fairly high speeds.

That being said if you daily drive your car and will road course a couple times a year, the MPS4 as mentioned above is probably the best all around tire for that. But I still don't believe you will get much more mileage out of any tire because you can not rotate them and that drastically reduces tread life. You will be replacing tires every 15-25k miles tops on these cars with spirited driving.

Weekend/warm weather car only. In the garage until spring right now. The odds of me road coursing are slim to none to be honest, maybe some day. More concerned about street traction without giving up handling. My old Toyo 315 DR on my 4th Gen were a little squirmy if that’s a word. Sounds like tech has improved. I’m leaning the 555r2 route.

Going with the g2 and r2 setup as well with the same sizes, will I need to relocate the wiring harness for these? I have 20x11 et 43 wheels going on the rear

Shouldn’t have to... OEM 1LE sizes if you are at factory height. I’m going to be lowered about 20mm so I’m going to check it.

The GYSC3R is a good dry track tire but will be a nightmare on the street and forget about anything more than crawling around if the roads are wet.

It's hard to imagine asking much from my car with drag radials on the street in dry or wet conditions. I found the stock 3R too slippery on dry roads and dangerous on wet. So I bought the 4S for the street.

Firestones are not available in 1LE sizes. I think the OEM Goodyear (non3R) is a great tire for track visits, but it will make the car jerk from side to side with road imperfections and is marginal in the rain, especially over 55mph. Mine started making noise at 8000 miles with no track visits and I rotated them side to side at 5000 miles. I would have to agree, the Conti Extreme Contact Sports or Michelin Pilot 4S's are the way to go. I'm not sure the 4S's are worth that much more than the Contis though. Both tires have a softer sidewall, which affects turn in. I could go with the Contis. Both are rated for 30k miles when you can rotate, which we can't, but I got 28k out of my 4S's on my 17 Camaro SS.

I drivin the 4S for the last 5 years on my GTR and now 1LE so I have no experience with the Contis

About the 4S, Tire Rack says, " It's the benchmark for a reason."

In terms of performance, the two tires are extremely close. They are both within about 1 second of a 200tw competition tire (RE71R, Rival S) in the dry on a typical autocross course. They are the two go-to tires for wet autocross and track duty. They are both high quality. They both last roughly the same amount of miles. A set of Contis is $272 cheaper than the Michelins on Tire Rack right now. If I were looking for the ultimate wet autocross/track tire where one or two tenths of a second matter, I'd probably opt for the Michelin. If I were looking for a great summer street tire, I'd save the money and opt for the Conti.
