My bad thought they were all season

Maybe I'm confusing them with the AZ850's then but one of them has bad reviews... don't remember which.

My recommendation, as always, is to switch to OEM SS 1LE wheels and a set of ultra high performance summer street tires such as the Michelin Pilot Sport 4S or the Continental ExtremeContact Sport 02.

This is an expensive proposition (although the Contis are a bit cheaper these days), however, not only is it not a downgrade in handling and traction, but it's actually a tangible, I'm tempted to say massive, improvement in both, especially compared to your base setup with the skinny Goodyear runflats that are junk. The real tradeoff is that you will want to down your car in the Jersey winter, which I used to do every year while I lived there, from December to March, sometimes April, but then I didn't want to destroy my forever Camaro with the crazy amount of salt on the roads anyway.

WIth such a combo, you will 1) be able to launch the car (provided you remain at stock power) and have great dry traction, 2) drive carefree in the rain no matter how intense, 3) have excellent cornering abilities, at least up to 1.1-1.2 g even on the street, 4) have nice and quiet tires with very low road noise, 5) have the best performace overall yet still be able to drive in 36-38 degree weather, and 5) have a killer looking wheel/tire combo, those SS 1LE are the most amazing looking 6th gen wheels ever designed (subjectively speaking).

If you go this route, my setup is 1LE wheels and 315/30/20 tires in the rear / 275/35/20 in the front, Michelin PS4S. Sizes are important, you can't deviate from your existing front:rear height ratios by more than ~3% without a custom tune, or your ABS and StabiliTrak systems can go haywire.

I have heard great things about the Michelin Pilot Sport 4S and am seriously debating running them. Only issue is the price but it seems as if people love them when they get them. I think I'm going to just keep the stock 245 set for wintertime until I run through them. Thank you for the response and all the info, really helps me out considering you mentioned things I didn't even think of lol.

Everything up to an SS1LE should be compatible, however a ZL1 1LE (often referred to as ZLE) has different wheel sizes/widths so be careful not to confuse which 1LE you are basing your upgrade on.

https://www.wheel-size.com/size/chev...4-62i--455-832

And if it helps I have a standard 2SS non 1LE

I use currently 305/35R20 rears and 285/35R20 fronts with 20x11 rear wheels with 43mm offset, and 20x10 front wheels with 20mm offset (At 35+ aspect you want to be careful on the rear driver side not to rub the wire harness this can be easily relocated I had mine relocated to be safe but a lot of people say 305/35R20's are fine without moving the wire harness) I sport Nitto 555R2's on the back and standard summer tires on the front (FYI Aturo AZ850's are dogshit for the front) But I do mostly drag racing soo the rear tires are what matters in my case.

The reason why I say be careful about the wire harness at 35+ aspect ratio is while normal driving is fine, if you do hard launches from a dig, the car will squat and that squatting can rub the wire harness. In my case I do a lot of drag racing so I chose to move my wire harness regardless if it was necessary or not.

Thanks for the response! I have read a lot about the wire harness can get in the way and it seems to be quite the pricey fix lol. I'm hoping to be able to get the new set up within the next month or two so I can be ready for summer. Thanks for all the help I'm prob gonna post an update once I cash out on a nice set.

If my budget allows this spring, I was thinking of getting this wheel/tire setup for a summer performance upgrade, great to hear this is working really well for you arpad!

JohnnyMac - Just one special consideration for LT1 model that we have, since we have smaller rear brakes than the SS model I recommend trying to keep the combined wheel+tire weight of the new much larger rear wheel setup at or below the current weight of the 8.5" wheel + 245 run-flats to make sure you don't put more unsprung weight on the rear brakes just to make sure you don't potentially hurt braking performance.
Fortunately, at least with my OEM wheel+the heavy runflats it comes in at ~60lbs which with quality wheels and top non-run flat summers or all-seasons I think should still be similar or less even at large 315 size.

Also, if your budget can't swing the significant $$$ for this setup (or for other LT1 owners that are still on stock wheel/tires) my current setup with upgraded rear wheels to matching 9.5" OEM wheels + 275/35/20 non-run flats high perf tires (Conti DWS06+ all seasons for me) is still a really good upgrade on looks & performance to get to same as stock SS (non-1LE) wheel/tire combo with great bang for buck vs the stock LT1 245 square setup w/run-flats and is almost perfectly same tire diameter.
Hope that helps - getting off the stock setup will be great upgrade for your LT1!

Thanks for the response, I didn't even consider that the rear doesn't have brembos and that the weight of the set up could impact my breaking ability. I am definitely going to go with one of the recommended set ups due to the amount of thought that really goes into a good set up when trying to perfect it. I love the idea of a budget friendly set up, I may even try that and see how I like it prior to balling out on smth insane. Thanks again!

(and just curious - are you still on stock wheels and the square 245 run-flats now?)

So as of right now I'm finally reviewing all of the responses I've gotten because I've been so busy with work lol. With that being said I am between going with 285 rears and 305 rears. Still unsure which one I am going to do but I've dialed it down to two. As far as tires go it seems like you can't go wrong with the Michelin sport p4s but holy cow are they pricey. Front wheels I am still unsure about but of course it would depend on what rear I land on. And unfortunately, I am still on the 245s. Due to the fact that i'm in Jersey im thinking that I can just rock them in the winter to not beat up my good set up. I've also read that the p4s can't even handle temps near what Jersey gets in the winter, so I would need another set up. I will post pics and an update post once the car is on its new set up

Tire prices have gone berserk lately... well, as an alternative, you can do something else that will still be helpful, namely you can go with the slightly cheaper Conti ECS 02 tires in a staggered setup of 255/40/20 front, 285/35/20 rear.

First, this will work with stock SS wheels that you can buy really cheap, and if you want to save even more, you can technically keep your 8.5" wide LT1 front wheels and only buy two 9.5" SS wheels, although I'm not sure if the same wheel design is available in this size---I'd probably just buy a full stock SS set of wheels off someone here in the forums. The speedo will be very slightly off, but you probably won't even notice.

Second, you'll still have much better and quieter tires, basically most of the advantages I listed, except your dry traction will be somewhat lower and you won't have the killer looking 305 or 315 steamrollers in the rear. However, you'll save at least a thousand if not more compared to an SS 1LE wheels + PS4S tires combo.

Your car, your money we just highlight some options for you to choose from.


One final word of caution if you go with 285/35/20 in the *front* as someone suggested: they're going to be extremely close to the wheel well when turning the steering wheel to full left lock on the driver and full right lock on the passenger side. I ran this setup with PS4S tires for a while, and the driver side tire did actually rub the liner (in a place with a hard metal part behind it), not too much, but enough for the wear to be visible. Not a dealbreaker IMO and each manufacturer's tire sizes are physically different even for the same nominal sizes (go figure, sheesh), just wanted to make sure you're aware.
