Re: How low to run et streets?

i just did a search because i trying to find the best PSI for street driving.. someone told me they run 27-30 for long trips?

but for lowest from what I just saw anything below 15psi is very unstable up top end. Some guys are running 18-25psi in them on the tracks and hooking fine. Im just gonna start at 19-20 and go from there with mine. Im definitly not going below 16 or 17 <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I've made a few passes at 15 psi with no problem. I did make a pass at 13 psi last Sunday again with no problem. I am running tubes.

Re: How low to run et streets?

back when i ran 26x11.5 ET streets on stock 16" wheels i had my best luck at 12psi warm (no tubes). hooked the best down there, and below that things started to get a little suirrley up high. this was on a stick car FWIW, i dont think you will need to go that low on a non t-brake auto to get it to hook up

On a good hookin track mine ran best at 20-22lbs. Run as much as you can and still hook. You will need to get em hot. Best on ET Streets was 11.30 with a 1.51 at 119. 3450lbs Race weight.

Re: How low to run et streets?

In my experience, the tires have grown 2psi after I have finished a run.

12-14psi cold really felt crappy for the last 1/8th of the track.

I like 15-17psi cold. I wonder how much the tires grow from the burnout, that's probably where most of the growth is from?

If you can run them 20psi cold the car will track like a Cadillac.

<hr /></blockquote>You got that right! I have had mine down to 12-14 psi for 2 runs and both times I got out of it because I couldn't deal with the way the car felt. This was with skinnies up front and no sway bar as well....
