I just went to check my tire pressure recommendations and what they actually are. The front are 33psi and the backs are 39-40psi.

The recommendations are 32psi front and 33psi back! But I'm a little confused about the recommendations cause there were lower numbers and higher numbers as well.

Should I deflate my back ones to 33?

As a rule, passenger cars should be running around 32psi. Any more than that and your car will be bouncing along the road. 38 is too much. I remember one of my dad's customers with a C4S coming in complaining about vibrations at high speed. My dad took it for a spin and entering the gardiner, punched it and almost went into the guardrail because the car started hoping sideways. He pulled over, check the pressure and it was at like 50+. He dropped the pressure and took it for another spin...another corner and the car turned like it was on rails. Moral of the story? Tire pressure is very important!!!!

I hope this lil p.o.s. reader actually reads properly. Ok so I deflate to 32front 33back?

The recommendations were like 29 and 30 for cold tires? and then it had a 32 and 33 w/ an upward arrow beside them for loaded, and then it had like 36 and 42 for max load so I'm not sure wth it was trying to say.

for stock rim sizes, you should run the recommended PSI as indicated.

Why would you run a higher pressure on a bigger rim with lower profile tire?????? That would make the car hop even more. 32 is the standard all around. Its a no brainer.

Most people run a higher pressure in a low profile. I run 40 in the rear and 38 fronts.

I used to run lower pressure but I had really bad tire wear.
