What is a good PSI to run F1's at the track
 

hey guys, im going to the track again tomorrow and im gonna swap out my 20's in the rear, and put on the 18's w/ F1's on them.... what is a good PSI to run them at for traction and drivibility???

I got the best results at 28 - 30 psi

I ran 24psi.

Last year at Milan I got my best (new tires) at 26psi. I went lower but it seemed to spin easier and loose 60' times.

WOT

26~27 for mine:thumbsup:

all these PSI #'s are when they are cold right? i dont want to put them at 26-28PSI and have them expand...

I leave mine alone - run them at street pressure. I was able to cut 1.85 60' all day long at Norwalk towards the end of last year... on the F1's (there were a few from here that witnessed this). All they need is cleaned off a bit, and roll into the throttle... works very well.

I ran mine at 22-25 lbs
and got 1.8 - 1.9 every launch last season, except one 2.0

Track prep has a lot to do with the different pressures you're seeing people post.

I've run them typically at 28 PSI and I've done horribly (2.1 best) at one track and a best of 1.84 at another.

I would start high and reduce from there depending on the resulting 60'.

Good luck!

I ran my F-1's at 20lbs and was able to cut a 1.86 60' on a good track

When I used to run F1's I ran them at 27psi
