that didnt have anything to do with tire pressure. The tires where proven defective. Im sure the pressure didn't help but it was defently bad tire making.

 

I SAY ROCK WHATEVER PRESSURE YOU LIKE AND WHAT FEELS GOOD AS FAR AS RIDE AND HANDLINGEXPERIMENT WITH DIFFERENT SETTINGS TO SEE WHAT SATISFIES YOU AND YOUR LIKES. I WORKED AT A TIRE SHOP FOR FIVE YEARS THE BEST THING TO DO IS INFLATE WITH NITROGEN AND DONT GO BELOW 34 OR ABOVE 44. JUST REMEMBER THE HIGHER YOU GO THE BETTER GAS MILEAGE BUT IT WILL ALSO WEAR DOWN THE CENTER OF THE TIRE MORE AND GIVE A HARDER RIDE. I HAVE 205/55/16'S AND I LIKE THEM AT 36 ALL YEAR ROUND IF I GO ON A LONG TRIP IN THE SUMMER ILL GO TO 40 TO SAVE A BIT ON GAS BUT OTHER THAN THAT.

 

i go 40 PSI all the time, check it every month. Over inflation= more center tread wear, under = more shoulder.

 

Had a hard time following the timelines of this thread but ok...

As a rule of thumb, I kinda take a guesstimate on tire pressure... We all know that 2/3 of the curb weight of our car is in the front... which makes about 1750 pounds in the front, and 850 in the rear. That means on EACH front tire, there is normally 875 pounds on each front tire... and 425 pounds on each rear tire... less than half of the fronts. So especially with wider-profile tires, this has asignificant effect from front to back.

Take a set of 205/40/17's, fill them all to 35 psi, then chalk them... you will notice that the fronts contact the road relatively evenly, but only about 60% of the rear tires plant themselves firmly on the pavement. An easy way to chalk your tires (if you have chalk obviously, no-brainer)... wash your tires down in the driveway quick (the tread). Then put down some chalk, sand, or whatever on the pavement... loosely, lightly, and evenly... and then slowly drive over the chalk keeping the wheels completely straight. This will give you a general idea of what areas of the tread are making the most contact per tire. This is also usefulto show ifyou have any camber alignment problems...

Bottom line, it depends on the tire. Me personally, I feel that the tread all around on my car (205/40/17) is dispersed evenly with 36 pounds in the front, and 30.5 in the rear... when the car is empty or just me in it. Sometimes you just have to expirement and figure out what works best for you.

Let me know if it is usefull.

i run 32 in the stock tires because thats what is recomended on the door sticker, but with the low profiles i go with 35 psi

 

oh and when i autocross w/ it i put them at about 50 - 55 depending how warm or cold it is outside
