The PSI indicated on the inside of the drivers door says max 32 PSI. On the tires themselves states Max PSI 53. When purchased from dealer PSI was at 40 PSI.

I hear people using PSI of 43 to 32 PSI.

What should it really be set at! And do you half to watch tire pressure closely in winter on Mazda factory Alloy Rims? I heard that the Allyo rims take twice as long to contract then tires do, so you constantly leak air, until contraction of rims is stable. Anyone have this problem! Waiting for winter myself to verify!

on my stock tires i kept the pressure at 32 PSI but on my 18's i keep the pressure at 36 PSI

 

Does anyone add/lower pressure for winter driving?

 

I keep it the same.

 

Not sure 100% but prob about 32 in fronts and about 26 in rears will be close enough :P

1/4 mile ?? 20 front and 40 back so max grip no drag lol

 

32-35 PSI is standard but a rule of thumb is lower profile tires need a higher pressure.
