For those of you running stock tires, was wondering what PSI you run them at and why? I've been running mine at 34 PSI (cold) lately and can definitely feel my ride is less harsh.

36-38 cold, goes to 40-42 hot (in CA). Just did whatever was standard i guess. Does it make it a big difference? I feel like i need to change out my stock tires for a better ride.

I keep mine right where they're supposed to be at 36. A lower psi is going to have a slight effect on your mileage. I've got an app to track it mathematically since the mpg meter in the car is usually way off. I once noticed a slight decrease after a fill up with no real difference in city/highway driving I did. Sure enough I checked the tires in the morning cold and they were all low at about 32. My car has been very consistent since I got it in December averaging 21.8 mpg +/- .3 (350-F). That tankful gave me 18.9, it's not much but considering the ride sucks on the stock tires anyway, I'll take the extra few miles. If your looking for a good ride, I rode in another 250-F with Pilot super sports and it was a very noticeable improvement, those are going on my car when the Bridgestones are done.

38, I may hit higher speeds and 38 is recommended if you want to drive real fast.
