how much air do you run in your slicks?

That seems like alot. I have 16.5x33s on a 2860lb car and run 6.5 to 7 psi. But every car is different.

14.5 x 32 good years on 2 cars. 6.5 in my 2650 pound truck and 6.75 pounds in my dads 3150 pound Nova... Only 5 in my 16 x 33's on my dragster... Hope this Helps!

In my experience 9.5 would be way too much. The thing to remember is that every guage is different and you should use the same guage everytime. I have 3 of the Moroso guages that are all the same part number, but all read a little different.

main thing is heavy car needs stiff side wall..

My motto is keep going up in Air pressure until it loses traction..run as much as you can in other words...why ?

1- car will be more stable.
2- it will be faster.

different tracks/time of season will require different air pressure, you must experiment each time...with a good middle of road starting point


wanna go real fast ?

get a radial slick to work with as much air as possible and you will have a fast tire... 8)

9lbs in 2800lb car w/ 32x14's. Tried 8 lbs but felt unstable.

ok then try 9.25 if it works go to 9.5 if it still hooks go to 9.75 and so on...like i said more air you can run faster and stabler it will be..

the main thing about air pressure is don't make huge jumps ..if you have a digital gauge you can sneek up on it a little slower..but a regular gauge 1/4 lb at a time.. :wink:

The 9lbs works great. Leaves hard everytime with the wheels in the air. Never tried 9.25 but 9.5 spun. 8)

Air Pressure
 
I run 8.5 -9.0 14.5 x 32 with tubes. I tried 7-7.5 but in photo's i noticed the tire was..for lack of a better term "folding over itself". Although hooked hard. With 8.5 i still see a little too much "folding". My car is an S10 weighing in at 2910 lbs.
Im going to put a smaller tire on it this winter tho.
