Going autocrossing 'morrow and was curious as to the best tire pressure F/R, respectively.

Car in sig w/BF goodrich Touring T/A tires P205/60/VR15. No suspension mods at all.

 

somewhere between 35-40 psi up front and 25-30 in the rear. also, keep in mind when adjusting the higher the tire pressure the more traction (so says the Mazda RX-7 Performance Handbook). I'm hitting the auto-x tomorrow as well, it's the first time for me and my car is relatively stock, should be good times .

 

one of the protege mods, who is really into autoX told me to put 42 front 46 rear on my protege, and said 45 all for anders car...

which should we do?

 

OH c'mon there HAS to be someone here who knows what to put....

 

You want higher than normal pressure.

As for what specific numbers your car needs....Well I dunno. Fill it up in the morning and get a gauge. Then let it out little by little until you find the sweet spot.

 

Alright thank.
