Hey Guys
I just got those much needed tires, pilot sports 225/40/18 front 285/30/18 front. What tire pressure should I run? My car fuel cap says 36 front 44 rear. Tire rack says 36 front and rear. I ask around and many places give very different numbers.

Thanks for your help

 

What type of driving do you do? What suspension? What type of roads are you on? These are all factors that will affect how much pressure you want to ride on. I go 36/44.

 

Tire Rack is wrong.
I've used stock pressure for 30,000 miles.

 

I drive my car alot not every day, but when I do I drive hard. I run stock suspension. Im just wondering what other guys are running. Thank you

 

Is stock pressure 36/44?
thanks

 

When cold, I run my tires about 2lbs. less than stock settings. When auto X about 4 lbs less.

Daily driver, 3.4l, with ROW M030

Go with Porsche recommendation 36/44 psi. Too low pressure offers less tire wear, poor ride, rim damage, poor mileage and more strain. 33 is too low for sure.

 

small thread jack.. I've been running 42/44. Can too much front tire pressure cause the front end sliding problem I'm having with sharp left turns? Or am I asking too much from the car/tire/PSS9 combo?

 

It's on your cap, right?

 

To each his own IMHO. . . With the higher tire pressures my *** end was sliding all over the place in the auto X.

During my daily driving I prefer close to stock or a little less with the Pirelli PZero Rosso's as they have a tendency to wear in a scalloped fashion.

36/44 cold on the street and on the track I run 36/44 measured hot.
