it's better to overshoot than undershoot because it's easier to dump a few psi rather than try to find an air tank and add psiWill do
Why the differences betw ZL1 1LE and SS 1LE?
Sorry for going off topic here, but blacksheep’s quote is exactly why for us guys who are not part of a race team a cordless tire inflator is SO helpful - I found the gauge to be perfectly accurate to the pound as tested against 2 other good gauges, hook it up and it inflates automatically to the pressure you set, set it and forget it. Compact, quick enough, and the batteries are used for my impact wrench (lug nuts) and all my other power tools - great for track days.it's better to overshoot than undershoot because it's easier to dump a few psi rather than try to find an air tank and add psi
you are correct,but I was referring to pit lane pressures, always overshoot, then dump psi after 6 laps, rather than hunt down a tank.

On 3R you wont go from 20 cold to 34 though.. Not in my experience. I would say first time out try 26 and that will probably land you around 33-34 hot.it's better to overshoot than undershoot because it's easier to dump a few psi rather than try to find an air tank and add psi
has anyone tried running them lower? It's been my experience that in almost every case, the mfg overstates the hot psi.On 3R you wont go from 20 cold to 34 though.. Not in my experience. I would say first time out try 26 and that will probably land you around 33-34 hot.
Also, not sure what tires you are used to... But session 1 in the AM take it very easy for the first lap or two. They are ice when stone cold and literally just skate right across the surface once they start sliding. . Once they start to grip up its a great tire though.
This I am not sure.. I usually hear guys talking in the 32-25 range , which is where I usually fall. I havent tried lower but may be worth a shothas anyone tried running them lower? It's been my experience that in almost every case, the mfg overstates the hot psi.
I run them at 32. That's a bit low, but they burn up so fast, I didn't find it makes a difference long-term. 34 will be the right balance if you are running a street alignment, tho.
Cold pressure will largely depend on the track and temps. I've gone out on 23 and as high as 27.
COTA raises tire temps a lot. It’s regularly 8-10 psi. Last event, I was concerned about under inflating some older pirelli slicks so I went out at 26 and one of the fronts reached 39. Obviously the best way to do it is to follow blacksheeps advice in and come in after 6 laps and lower pressures.What conditions have you needed to decrease to 23? With my limited experience I've been reluctant to go below 26 cold even though it looks like I'm not using the entire tire footprint (about 10mm of out sidewall only scuffed) with -2.45 camber. Maybe I'll try less pressure next track weekend?
