Why not go all the way close to 1LE specs then, though? The price difference will not be astronomical given you already committed to buying new wheels plus tires, and it tangibly improved handling for me even over the staggered SS setup. I'm running 275/35/20 front on 10" and 315/30/20 rear on 11" wheels.

If you want to do a square setup to save tire costs later, that's understandable, although IMO you will compromise either traction (rear) or steering response (front). I'll let someone who does run a square setup comment any further, though.

How much did it cost to move up to that setup.

Going to be an expensive year, BUT, two sets of rims and tires specifically adapted to the seasons I drive in. Both sets will last years so it's not like you have to do it again every year.
The only dinking around is swapping them in your garage winter and spring, plus maybe driving to the dealer to have the TPMS reprogrammed.
But having the TPMS reprogrammed is usually a drop into the dealer or discount tire for 10 minutes. You don't have to wait hours each season for them to remount wheels.

come to think of it, don't go to the dealer for wheels or tires.

What he said....
We just got a 2SS. In January. I was surprised by the stock summer only tires being a problem simply parking the car outside if temps get too low. So I got a set of Flow One wheels in 18x8.5 and put Vredestien Snows on in 245/hmmm I forget but I think 60/18. Have not driven in the snow but it was fine as far as spinning them in the dry. Im sure I could if I wanted.
I spent just about 1200 bucks delivered mounted and balanced. I had a friend program the TPMS and that will need to be done each swap. But Tire Rack sells a programmer for I thing under $50.

I’m willing to compromise one of the 2 for the square setup, just not sure which I’d rather give up.

Been covered do a search on it, for the love of Pete

$3k in total for the MRR 1LE replica wheels and PS4S tires.

Guys, the advice here is straying somewhat from reality. Let's go back to the OP:

If you don't want to buy a second set of wheels, you can do exactly this. You need to look at higher-performance "summer tires" like the Michelin Pilot Sport 4S or Continental ExtremeContact Sport. They both come in your car's OE tire size and would be massive improvements in dry and wet grip (but not in snow/ice). Wider is pretty much always grippier, but there is a bigger difference in grip by switching to more performance-oriented tires than by keeping the same type of tire but just going wider.

A lot of people keep two sets: one for warm months and one for winter. You can also certainly go that route. If you do that, then I agree with those advising you to go with either the SS or 1LE sizing. If you're going to get new wheels for performance, then yeah, you might as well go wider. You can go with the same diameter and width front and rear if you prefer, but a truly "square" setup has the same offset front and rear also and our Camaros don't support this. You can do it if you get the offset for the rear spec and then use spacers up front, but you will then probably need to get longer wheels studs. As someone already wrote, there are other threads that go deep into this topic if you are really interested. Just search for "square" in the title.

If I can keep the stock rims whats the widest tire size I can put on them? I have the "carbon flash painted 20" rims"

If you do that, stick with the stock tire size of 245/40/20. Going wider will not likely generate more grip because they'll not be as well supported due to the 8.5" wheels. They'll also be taller if you stay with 40 series, which is actually bad for performance in several ways. There's no point trying to squeeze wider tires onto your stock wheel size.

And finally why does it seem like every tire shop online either doesn't have 2021 as an option yet and if they do doesn't have the lt1 as an option for the camaro?

It does seem to take most of a year for their databases to catch up.

I did a square set up 275/40/19 with Firestone Firehawk Indy 500's and really like them.

How do you find the noise on the PS’s? Wife’s CTS had Pirelli P Zero Nero run flats as OEM and we got Mich PS AS’s to replace them last year and they seem really loud compared to the Pirellis. Really annoying on a Caddy that’s supposed to be a quiet luxury car! Granted it’s got the upgraded 18’s (and a stiffer ride) from std 17’s, but it used to be quieter.

Very low, these non-runflat PS4S tires are much quieter on the Camaro than the OEM Goodyears. I can hardly hear them over the engine and normal wind noise levels even when cruising at 1500 rpm.

Put another way, the stock Goodyears were much more rumbly and "whooshy", if that makes sense, I had to raise my voice a little to carry on conversations in the car, whereas these PS4S tires are nearly silent.

Interesting. Must be a run flat thing as ours are indeed run flat PSAS. Best description I can give is that sound of an off road or aggressive 4x4 tire, the more “knobby” kind that gives off a whine. Not nearly as bad, of course, but never heard that with the Pirellis.

I put on a set of 1LE wheels on my LT1. They look great and the car handles really well. I'll keep my stock LT1 wheels for winter use, or I may install a set of high perf all-seasons on the 1LE wheels and use them year round.

[ProdigalLunatic]

I love that Rally green. Wish had still been available on the '21s. Looks sharp! I'd like to do the same thing you did, pick up some 1LE wheels. But that may be next year's project. I'm jealous.

Yep, the run-flats have a completely different sidewall construction and they are hard as rocks. Just ask the guys that have to mount them! That's why they are so noisy.
