Proper PSI for 225/45/17 - Mazda 6 Forums : Mazda 6 / Mazda Atenza Forum

gmm150 · 09-08-2008, 10:09 AM

I am currently running Bridgestone 225/45/17 with a 91 load index.I usuallykeep them around 33-34 psi. I believe mazda recommends 32psi for the OEM/stock tires. Should I maintain a 32psi or what do you all recommend. I did search and read a couple posted about load index but I am still not sure. I think I saw some http://forum.mazda6club.com/index.php?showtopic=33026 that for my tiresize I should use 35psi but I didn't speciy at what load rating.

My tires always look low and people always comment to me that I have a flat or that I should check my psi.

Depends on the tire. I like having mine at around 38-40 and won't go below 36. When I autocross it goes to 48.

I actually have BF-goodridge g-force sport (not bridgestone sorry for mistake).
