Re: Camaro hunting
Trying to figure out spare rims and all seasons. Looks like Regular SS 20's fit, but are also different sizes:
Here are some ideas people had on forums:
Front: 20x8 (23mm offset) with Goodyear Eagle GT tires 245/45ZR20
Rear: 20x9 (42mm offset) with Goodyear Eagle GT tires 275/40ZR20
This sucks because I want to keep the sizes the same or at least "square"
These seem popular also:
Michelin Pilot Sport A/S 3

Re: Camaro hunting
Also found out the real reason for different rim width in the back is to just use the ZL1 rim because there is a different offset for the back than the front, so you can't just put the front rims on the back. They would have had to make the front rim size with the rear offset.
Re: Camaro hunting
I am not sure I really want to get rims that are not going to support the stock tire size that is on the car now... So stock SS rims might be out...

Re: Camaro hunting

So the SS rears are 1" wider, but with 19mm additional offset (19mm is about 75% of 25.4mm). This means that the extra 1" width is split with 0.75" of it going on the inside and only 0.25" going on the outside.
The 1LE is almost the same with 79% of the extra width going on the inside of the wheel.
I don't know how much any of this matters as far as running stock SS wheels. Obviously you can run the same width tire on different width wheels. And you can run different width tires on the same width wheels, such as on my STS. You just need to stay inside of a reasonable range.
Without looking up any guidance, on an 8" wheel, I'd say 245 is about ideal. I don't know if that would be OK to stretch to 275. I'm sure it would mount but not sure how it would handle.
More math validation: 275-245 = 30mm, which is a little over an inch. So 245/275 on 8"/9" wheels sounds pretty ideal. Again the question is deviating from that.
255/40R20 is the closest size that is narrower that is only 0.4% taller than your stock tires. The tire calc website I used says that an 8.5"-10" width is ideal for that size so 8 and 9" seems pretty good from that perspective. Tirerack offers 42 tires in that size.
The thing about 245/275 (I assume that is the stock SS size), is the SS and 1LE do not run exactly the same diameter tire. Specifically, the SS runs a little taller tire (which is why there is more wheel well gap on the 1LE). Granted we are talking about a 3% error, which is a 2mph error at 70 mph. But the 255/40R20 is like only a quarter of that error being off by only 0.5 mph at 70 mph.
One additional note: for matching the stock diameter (in terms of speedo error), you are best advised to look at the revs/mile spec, rather than calculate the diameter based on the size. There is some rounding and other variation that can impact actual rolling diameter that the revs/mile captures. So I used the size specs to calculate speedo error - you'd want to use revs/mile to get the most accurate prediction.
The stock Goodyears are 750 revs/mile.
Cheapest all season in 255/40R20 is a Yokohama Parada Spec-X Street/Sport Truck All-Season. $193.82/tire.
Next cheapest all season in 255/40R20 is a Hankook Ventus S1 noble2/Ultra High Performance All-Season. $200.95/tire.
So those are your cheapest Tire Rack options for all seasons to run on stock SS wheels in matching sizes.
That is why they are different offset.If the offset of the wheel is not correct for the car, the handling can be adversely affected. Often, when changing the width of the wheel, the offset will also need to change to maintain proper clearances inside the wheel well. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly.
So the SS rears are 1" wider, but with 19mm additional offset (19mm is about 75% of 25.4mm). This means that the extra 1" width is split with 0.75" of it going on the inside and only 0.25" going on the outside.

Re: Camaro hunting
So Bill indicated that he'd rather run the right size wheels and tires, since the "off season" for the Goodyears may be a bit wide considering he's trying to maintain a mostly year-round situation (minus rain, snow and salt I assume). So may as well run a good set of tires even in the off season.
Given that, Michelin makes the PILOT SPORT A/S 3+ (W- OR Y-SPEED RATED) - SIZE: 285/35ZR20
Ultra High Performance All-Season
It is only $246/ea which is surprisingly not much more than the 255/40-20 stuff I had above. The biggest cost hurdle will be getting another set of wheels. And take-off 1LE/ZL1 wheels are probably the way to go.
I am not sure what the 3+ designation means except marketing speak for "ultra high performance all seasons" which as a category has been around for a good 2 decades now. It is the same class as the Continentals on my STS, which I think are a HUGE step down from the Michelin Pilot Super Sports on my CTS-V. But apparently the Sport A/S 3+ is pretty good.
Tirerack reviews from 1LE owners:
This one is not so good but he only had 600 miles on them when he wrote this review:
You are going to pay more bucks though. The successor appears to be the Pilot Sport 4S (which is confusingly NOT an all-season). Looking at around $350/tire for these. Given the budget is already stretched, this option probably won't work out, as it adds another $400 to the transaction. I do think the performance would be noticeably better.
Oh. This is a problem. Found this on the 4S page:

I have a 2013 Camaro SS/1LE and have used two sets of the Goodyear SuperCar G2 so they are my reference. The OEM Goodyear was like a hockey puck below 55F and dangerous to drive on until warmed up. When hot, they were on par with almost any 100TW tire on track. I also have a 2011 Corvette Grand Sport with Michelin Pilot Super Sports and no complaints. Now for the Michelin Pilot Sport A/S 3. I figured I would try the Pilot A/S 3 to use the Camaro more often as a 3 season car. This is by far the nosiest tire I have ever had in terms of squeaks and squeals. The first thing I noticed was the embarrassing high pitch squeal under normal acceleration from a light when I hit the white crosswalk line. The second issue is when making a left or right turn with any sort of acceleration. Not flooring the car, just rush hour need to make the turn type of driving. The other major item is the premature activation of the ABS under any hard braking. The level of grip is subpar which activates the ABS in any stop that is spirited. I gave the tires the benefit of the doubt and hoped they would gain some traction after the initial break-in and heat cycles, they did not. I went as far is doing a smoky burnout to scuff the tires and they are still just as noisy. These tire remind me of driving a 2014 Chrysler T&C with Michelin A/S and I will be replacing them with a Pirelli P-Zero.
I guess my personal preference would be to pitch the "summer" PSS and know that the car is going to be down except on mild winter days where the high is above freezing. It hasn't snowed yet this year. But once it does, are you really going to drive the car even on the dry salt? That would be my sales pitch for a summer tire like the PSS. And depending on how frequently you drove the car in the winter, you may be able to completely switch to a Max Performance Summer tire (meaning no new wheels required).Tire:Michelin Pilot Super Sport

I replaced my Eagle F1's with theses tires, which I had on my WRX as original equipment. The F1's stuck like glue in the summer on a perfect day only. I live in OH and there's rarely a perfect day. The F1's in the morning when it was cold, slid like crazy and I could barely old the car in a straight line with the lightest of rain. I recommendd the Super Sports to everyone i talk to. They are a great tire in the rain and great in the summer. They have a much wider range of drive ability than the F1's. I never go to take the F1's to the track, but for everyday driving here in OH, the Super Sports are a much better tire.
You are going to pay more bucks though. The successor appears to be the Pilot Sport 4S (which is confusingly NOT an all-season). Looking at around $350/tire for these. Given the budget is already stretched, this option probably won't work out, as it adds another $400 to the transaction. I do think the performance would be noticeably better.
Oh. This is a problem. Found this on the 4S page:
Sigh. I really hope that does not apply to my older PSS tires...I better inspect mine before I drive it next.Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels or using them to support, roll or drive a vehicle.
Flexing of the specialized rubber compounds used in Max Performance Summer tires during cold-weather use can result in irreversible compound cracking. Compound cracking is not a warrantable condition because it occurs as the result of improper use or storage, tires exhibiting compound cracking must be replaced.
Re: Camaro hunting
The Pilot Sport A/S 3+ has a 45,000 mile treadwear warranty (in this size - some are only 30,000, and all runflats are 30k) if the tires are the same front and rear. How convenient!
I can also say a few things....in footnote 1, the Conti DW, I had those on my CTS-V for 60 miles or so. Did not like them. Would not hold them up as a pinnacle of summer tire performance, even though they may be pretty popular. The PSS was notably and significantly better in all aspects except ride. And you pretty much can't have rapid responding tires that also ride softly. Doesn't work that way.
Additionally, in footnote 2, they mention the Conti DWS. I have those on my STS now. Another popular tire. I do like the DWS as an all season more than I like the DW as a summer tire, FWIW. But the point is, they are trying to draw a picture that they are better than all of their ultra high performance peers, but also as good as one summer tire (in dry braking). OK. But do you think Michelin would turn around and say they made an all season tire with a 45k mile warranty that is just as good as their summer Pilot Super Sport or 4S? Hell no. There is no way.
Again as a street tire, I would probably favor one of those summer Michelins since the Goodyears on the car now need to be warmed up more to get optimal traction. I just think the Michelin offerings have a wider range of performance, especially for a street vehicle.
The footnotes:Benefits of Michelin:
Dominate summer with more dry grip than a leading competitive max performance summer tire.[1]
Corner with exacting control. Our Variable Contact Patch 3.0 spreads cornering pressures evenly over the contact patch for more grip and control, plus long-lasting tires.
Control the moment with the shortest braking - wet or dry - of leading competitive all-season UHP tires.[2]
You're in control, even when the weather is trying to take over. Our groundbreaking Extreme Silica+ compound stays grippy when wet, while large rain grooves and 3-D sipes help prevent hydroplaning.
Shrug off winter with 28% better snow traction than the MICHELIN® Pilot® Sport A/S 3.[3]
A little ice or snow won't slow you down, thanks to advanced Helio+ Technology™ that's built to stick even in the cold. Plus, hidden Biting Edges grab loose snow for fast starts and stops.
I see a lot of claims but the referenced comparisons are in braking. You say "dry grip" and "summer tire" and I am going to assume certain things.1.
