ithat is totally up to your setup (particularly transmision), launch rpm, and your track. i would start at 20 psi and go down untill you are not hooking any better. i wouldnt suggest any lower than 12 psi or it gets real unstable up top.

I run 12 Psi cold in mine, no tubes or screws.

i'll be launching at 2400 rpm with my a-4 and also got a tci ssf torque converter rated at 3000-3500

I run 12-13 psi and leave the line @ 6700 RPM

what size et streets? 15 or 16" wheel? that makes a big difference in stability with more or less sidewall.

I ran mine around 14psi hot (11-12psi cold)

Yeap. I run mine 26x11.5x15 at 10 psi that is the only way I get them to hook with my setup.

Dam I tried running mine low around 13lb and my traction got worse , my car seems to like 17lb hot I guess every car is different. Check pic

I've run both the 16" and now the 15" on my car - with both I started around 20# and go down till I don't hook any better. It will depend on the track conditions and car setup. I never ended up below 17# on my 16" (less power then) and I don't get below 15# on my 15"ers.

I worked on the car setup first and got it optimized, now I use tire pressure to compensate for a slippery track (as much as possible anyway).

I usually run about 13-14 in mine

Send the tubes back. You won't need them and the extra rotational mass.

IMO I would not run tubes or screws.

I have run anywhere from 11 to 25 psi.

But, I would run them at 20 psi or lower when cold. They can gain 2 psi from your burnout.

I don't like to run them lower than 14 psi because they they track funny on the big end.

11-12 psi, and you might spin the tire on the rim.

so i won't loose pressure? and i'm going to be completely safe with out tubes?


i paid over $100.00 for mickey thompson tube's which i did'nt want to buy!

The more air you have in them and still hook the better. You wont loose any mph with more psi. I run anywhere from 18-20 psi. in mine.

You'll loose pressure in any tire, mostly from the changes in temp and you'll be safe and fine without them. You don't plan on having these on a daily driver do you?

ram air camaro

the et's tire's will be strictly for track use only no street.

i'm wondering if i should return the tubes i could use those $100.00 in something else?

Cool. I've gotten caught in the rain with them on the car and look out...

I spoke my peace about 'em, you decide.

If u run tubes you should screw the rims too.

Cuz if the tires move the valvestem could get pinched off.

If u run without tubes the tires may lose 4-5 psi over a couple of weeks.

I run 28's and don't run tubes or screws.

I'd run the tires at 15, 18, and 21 psi and see what works best.
