ZL1 1LE Tire discussion
Thanks to everyone contributing to the forum. It has been a great resource of information and recommendations.
I would like to start a discussion on ZL1 1LE tires. I am going to open with several questions, but am open to any feedback. I purchased my 2023 ZL1 1LE last summer. I have been driving on the OEM Eagle F1 Supercar 3Rs. I have to store the car in the winter. I only have 2000 miles on the car and I have about 1.5mm of tread left (5/32" new = 3.97mm)(I tried to get a recommendation on min tread from Goodyear, but no repose). I want to track the car, but I do not currently intend to have 2 sets of tires for street and track. Q1 (Temp): Interesting the dash display shows a color for tire temp. It is always green on my street driving. I am assuming green is good for cold temp, but as I understand, these tires need heat to grip. So will this color change to yellow or red on the track? Is that good? It would be great if it changed color when the tires are up to temp while on track real time. I did purchase an IR temp gun, but I do not know what the target temp should be. Q2 (Pressure): I see in the High Performance manual has recommended cold tire temps. 26 psi for Road Course. 44 psi for sustained high speed. So what category would 15-20 minute sessions be categorized at Road America in Wisconsin? Any recommendations? Maybe this ties back to the temp at the end of a session, adjust tire pressure to get the target temp??? Q3 (Tires): I will soon need tires. I would like to stick with the Eagle F1 Supercar 3R, maybe the Pilot Sport Cup for longer tread life. I would not drive the 3Rs in rain, what about the Pilot Sport Cup? That could wreck a day at the track plus limit when I take it out for a drive. I am thinking about the F1 Supercar 3 or Pilot Sport 4S. Q4 (Autocross): I am not sure this is a question. Autocrossing does not allow any heat to build or sustain in the tires. So I am assuming I just need to live with poor traction while autocrossing. Ps, The ZL1Addons rock guards work great. PPS., I did use tire cradles when I stored it. I have not noticed any flat spots. I found a set that are wide enough for the 325 rears. I had to jack the car up to precisely locate them. PPPS., interesting thread on oil temps at the track as I have an A10. Any comments on tires for street, Road Course, or autocross are appreciated. Thanks! |

Q1: yup, your tire temps should never be past the NORMAL (green) zone on the street, or you're doing something really, hm, bold. The temp ranges are COLD (white), COOL (light blue), NORMAL (green), WARM (orange) and HOT (red), and yes, you will enter at least the WARM zone on the road course.
Unfortunately, I don't know zone boundary temperatures, I think I have an old Corvette chart, but this is a different platform, the zone setup is probably different. Q2: "Sustained high speed" driving means 150 mph+ at wide open throttle for at least a few minutes, max speed runs on the Autobahn (or the "Autobahn" ). I don't think a road course where you only spend a few seconds, if that, at those speeds would qualify, and I have never heard of anyone going for these super high cold pressures. I'll have to check, but if memory serves, even GM didn't use these during the official ZL1 1LE Nürburgring run, and that track has a back straight that is 1.5+ miles long and took 30+ seconds for the ZL1 1LE, reacing 170+ mph by the end. Q3: There is no tire that isn't a compromise in some way for two so wildly different purposes (street and road course), The F1 Supercar 3 is not as good on the track as your current 3R and still only okay on the street, while the Pilot Sport 4S is primarily a street tire, you will probably find it mushy and sacrifice several seconds per lap on the track (if you're a good enough driver, unlike me, that is ), The Pilot Sport Cup 2 is also more of a track tire... but if you really never want to drive in inclement weather, I think you can live with these track tires on the street. However, treadwear will suck and it's counterintuitive to just putt the tread away on these super expensive sets driving on the street. All in all, I think people who are serious about both track and street driving bite the bullet and have at least two sets of wheels and tires. If you only occasionally track the car, but drive it a lot on the street, I'd suggest the Pilot Sport 4S (I have it as well), this is the best street tire and is probably okay on the track, too, until you are good enough to be bothered by its softer, street optimized stature.

As far as tire choice goes, I would highly recommend getting the regular Supercar 3's. For your use the 3R's don't really make sense. The SC3's have 90% the same grip as the SC3R's, last much longer and take less time to heat up in my experience. I have a set of 305/325 SC3's and another set of wheels with 305/325 SC3R's and I see about 1 second difference between the two. Another great option would be RT660's as a dual purpose tire. I have a 3rd set of wheels with 305/325 PS4S's and they are great street/daily tires, but they suck on track. I run both the SC3's and SC3R's at 34psi hot.

I will disagree with most opinions about the Pilot sport cup 2's for the track. I have used them for about three years now on my ZLE on a set of apex wheels, I am an intermediate driver and I do not have an issue with them during a 30 minute session in Florida. They are garbage in the rain just like the 3r's so in those cases I have used my Ps4S on my stock wheels on track.

I'm not bashing Michelin, they are great tires. I personally have a set of Pilot Super Sports (99Y BMW* fronts and 103Y Ferarri K3 rears) on a set of SS 1LE wheels for street use and they are wonderful tires. Better than the 4S in feel, response, grip, stiffness. Huge difference there, and I've driven the 4S' on an SS 1LE also. After that drive I was convinced to never buy the 4S for my SS 1LE. All the great things of the OE SC3 tire....gone with the 4S. Overrated on the SS 1LE or ZL1 IMO. Unless one wants a softer tire with less feel and response The PSS was at least equal to the SC3 in the above performance metrics. They were great in moderate to heavy rain on a trip to the Smokey Mtns last summer and excellent on the Tail of the Dragon and other fun roads. I led our group and my buddy said "dude, you are flying!". Is the 4S a better rain tire? possibly. But I had no problems on the PSS.

For those who run additional wheels/tires (in addition to the OEM wheels), do you add sensors to the rims for the car to read temperature? I know they have the TPMS for pressure. Do you have any recommendations?

For the street setup (stock rims with street tires) I had TPMS in them. |

The F1 Supercar 3 is probably the best compromise tire for street and track if you only had one set of wheels at tires, but I don't think they make them in OEM 1LE size. The Toyo R888R is another great tire both both purposes but its very expensive compared to the SC3 and it howls like a banshee which sucks for street driving.
