Simple 1LE Tire Pressure Question

[Dropspeed]

Very simply, what tire pressure do you set you 1LE tires at when cold for daily driving.?

Door jam says 32/32. Owners manual says 44psi for speeds over 100mph.

I do have experience setting up cars.....just curious what everyone else is doing with these for daily driving

FYI This is 1LE specific and not even ZL1 with the same wheels because it is 300lbs heavier, different suspension, different rear tires....

Thanks
Matt

I'm running 32 front and 32 in the rear.

Mine was delivered at 31. Same range as any other street car/tire I've owned. Typical street tire pressure is 30 - 35. Aside from track use, this car/tire is no different.

I shoot for 32.

Where does it say 44psi over 100mph? 32 cold and close to 40psi hot during track

Page 10-58 in your Camaro owners manual. I just searched for it myself and found it there. Here's a copy and paste from the paragraphs of the owners manual.

10-58 Vehicle Care
Make sure vehicles with 245/
45ZR20 103Y, P245/50ZR19 104W
and 275/40ZR20 106Y size tires are
inflated to the recommended cold
inflation pressures before operating
the vehicle at speeds over 160 km/h

(100 mph). See

Vehicle Load Limits on page 9‑12
and Tire Pressure on page 10‑56.

Make sure vehicles with 285/
35ZR20 (100Y), and 305/35ZR20
(104Y) size tires are inflated to
300 kPa (44 psi) before operating

the vehicle at speeds of 160 km/h

(100 mph) or higher.
Return the tires to the
recommended cold tire inflation
pressure when high-speed driving
has ended. See

Vehicle Load Limits

on page 9‑12 and Tire Pressure on

page 10‑56.

Need some clarification. I have run my 1LE six track days so far this year. I have never started the tire pressure off at 44 psi cold. The track I ran was a clockwise rotation and the left front gains 3 psi more than the rears. The air temp was in the 30's in March and in the high 50's in April. The rears had 30 psi at cold and after the 25 minute sessions had 36 psi. If anyone has run these tires at 44 psi cold on a road course I would like to hear the hot psi readings.

I was under the impression that the only advantage to running high pressures for high speeds was to reduce rolling resistance due to a smaller contact patch. I'm not exactly a physics expert, but wouldn't this just make it easier/faster 0-100mph? Is there any other advantage to high pressures as opposed to standard 32-35psi for high speed operation?

Sorta OT I know, but inquiring minds want to know

Thank you for all of the responses.

My questions was purely to see what everyone else was doing with theirs.

I am running 32 cold as well, and will start at about 38 cold next weekend when she hits the track.

Yes, lots of factors can go into setting the air pressure at the track, this was simply a daily driving psi question.

Thanks,
Matt

I run mine at 30 psi cold. It goes up to about 33 with mixed driving ie. city/highway. If I do a 100+ mph blast I don't think twice about my tire pressure. If I was going to do a top speed run at an event I would bump up the psi. I'd research what to psi use.


The car came with roughly 36 psi or 38 psi and it felt like a frigging stage coach.
