If the temperatures out there are really hot like high 90's to 100 F then go with 33. It is funny I set cold tire pressure at 34 in front 37 in the rear. When I got back from a weeks vacation and got back in the car my TPM told me I had low pressure in my tires. When I checked them every tire was exactly 3 psi lower. I was also alot cooler that day it got to 60 F in the morning when usually it has been around 77 F. No air leaked out it was just so much cooler that I lost 3 psi.
