From my limited research, their temperature profiles are certainly different. The SC3Rs have little to no grip at lower temperatures, but they were able to do a 7:16:04 at the Nürburgring, often cornering at triple digit speeds when they have enough heat in them. Then again, they can be even more compromised for normal street driving. Different drivers, different purposes.

the 3R are ~$300 dollars more expensive on tire rack. For the set.

SC3 is the same. It takes time for them to heat up to get any grip. GM states for both the 3 and 3r to not be driven in the rain or under a certain temperature, 60 I think.

All those that say you can drive the 3 in the rain are idiots just like the ones that say you can drive drag radial tires in the rain. Yes, if you're going 10 or more under the limit and easing into the throttle and not on the throttle after making a turn until you're completely straight.

Price? Come on....

Why is it that GM said both the 3 and 3r aren't meant to be driven in the rain or snow or under a certain temp? Didn't sound like a street oriented tire to me.

The 3 has been on the ZL1 since 2017. We all know and have discussed the differences but we all know, at least I thought so, that they are both road course oriented tires that can be driven on the street under the right conditions and are hands down the best road course going tires before you have to go to slicks since the both give you maximum grip until they cord unlike every other street tire that's good on a road course.

the 3 has an R next to it? Should I link the brochures? The reason for the not so expected relevant answer is because anyone can simply google and see that the 3R has a tread wear rating that's less than half of the 3.

As I understand it the 3R is made specifically for the 1LE track pack.

Alright you got me. The 3 does have an R next to to but it seems you're still learning.

A simple Google search will show you how great both tires are and how they both aren't meant for daily street duty and how many of us drive the crap out of each tire at the road course and leave street duty to a real street tire.

But there are a lot of tires "made" for certain cars. Like the PS4S is made for the CT5 Blackwing, 911 (992 version), etc.

Ok well I guess I'll just go with Tire racks categories.

The 3 is a "Extreme Performance Summer" tire

The 3R is a "Streetable Track and Competition" tire.

Both are legal road course street tires then, yes?

[Mike818]

The way I look at it, the ZL1 is a road car you can track and the ZLE is a track car you can road.

The ZLE is about 15 secs faster at The Ring than a ZL1, and will very likely be the most track focused V8 Camaro ever built and the last one with a manual.
Some will track it and some just want it to say they have the halo car.
I find nothing wrong with either.

Very few use a ZL1 to its potential either, but they don’t want an SS 1LE regardless, and that’s a beast on track.

Get what you want and enjoy it.

Haha well said. I know so many guys who dump truckloads of money into their cars, trying to squeeze every last ounce of performance from it, while not realizing that addressing their being 300lbs or more of “human ballast” could be the cheapest and most effective mod they could ever do.

If weight savings means that much to you, then start with looking in the mirror first.

Do you have much track experience on the 3R? It's an R (race) compound tire and the Supercar 3 is not an R compound tire, the compound rating is the key distinction--the SC3 tread depth and pattern, that helps with water and tire life, is the other distinction.

The 3R is currently the best DOT track tire in the world IMO, I have 3 sets in my garage with various levels of usage from new to nearly done (and also a set of A7 and Pirelli DH). In 5 years I've purchased 15-20 sets of 3Rs, never SC3 because they are not R comp and therefore not good enough for advanced track use and lap times.

But I would consider SC 3 for spirited street use and rainy days at the track--I prefer PS4S for street. The unique strength for the SC3 is that it can handle real track heat without crumbling, other similar high performance street tires like PS4S do not hold up under repeated track heat cycles like the SC3.

3R have set lap records/near records at tracks I frequent in CA, usually mounted to a McLaren 720 or a GT3 RS. Many skilled McLaren and GT3 drivers say 3R are the preferred DOT track tire--non DOT I love the Pirelli DH. The point is these are pure track tires, and SC 3 are not.

SC 3 were designed for some track use but mostly for spirited driving on canyons, curves or backroads at street legal speeds, where the driver can't achieve the accel/turning/braking forces to make super-heated R comp tires like the 3R, R7 or DH literally melt and stick.

A few things going on here. Even within a specific tire category and type, the OEM’s work with the tire manufacturer to develop a tire for a specific chassis. I can assure you this happened with the 1LE. Aside from the simple fact that the ZL1 uses a 20” tire vs the 19” tires and width as well as aspect ratio. Then, add to that the R spec. Yes the chassis/dampeners etc. and tires were developed as a unit. This is exactly why swapping aftermarket parts be it chassis, powertrain are virtually never a true OEM level upgrade. There is always a compromise.
