I woudn't use 32 psi. There really is no correct psi because.... The lower your psi the more grip you will have but your tyre will wear out more and you will not have as good gas millage. If your psi was higher like at about 40 you will get less grip but good gas millage and you will probably feel the road. I had my ones at 44psi which was maximum air pressure for my tyre and I noticed I was getting 750km's worth of gas
for about 5 months and it went worse but that's because the car was due for another oil change. Did the oil change and it's back up again. But if you do do that be safe on the road no speeding and don't follow people too closely
