    what air pressure for big slix

    I wasn't sure what topic to go to.I guess this will be it.I am in the process of tubbing my car and am unsure as to what ir pressure to start testing with.Before I was running 28x9 ET Drags and was setting them at 11.25 on the driver side and 11.00 on the passenger.The car would never sit still long enough to do a burnout withh 11 on both sides.Acted like driver side was trying to come around.We decided that since I was sitting on that side,maybe the extra weight was causing a larger foorprint.Always ran a quarter pound more after that and had no problems. :? I am going with a 33x16 tire in the back now.Way bigger than what I need,but worth some serious style points .So where to start?I've been told around 8 psi,but will that be enough to be stable?Any and all points of views and ideas welcome.Thanks

    Spib is right the manufacturer knows the most about their tires, that said I would start with 9-10 lbs and work from there.

    my dads nova weighs 3180 and we run 7 pounds in a 16x33 goodyear slick on it...I only run 5.5 in my 17x33 on the dragster but that isnt helpful here..lol...I Hope this helps... As far as uneven tire pressure sounds like you need some preload???
