The 55 series already has a stiffer sidewall and will ride firmer and harsher than the 65 series. Adding more psi will only make it worse, unless that is what you actually want.So I changed my 205-65-15 inch tires to 205-55-16 tires, on 16 inch wheels of course, and wondering if since the sidewall is now shorter, if I should still run the stock 35 psi or is another psi more appropriate?

Assuming OP has a Mustang, I would think he's not using it for hauling so not an issue.A standard load 205/65R15 is a 94 rating. A standard load 205/55R16 is a 91.
But it does affect recommended tire pressureAssuming OP has a Mustang, I would think he's not using it for hauling so not an issue.
What about it? That's on a sticker in the door jamb.But it does affect recommended tire pressure
But if the new tires have a load rating that's higher or lower than what is on the door jamb, pressures should be adjusted.What about it? That's on a sticker in the door jamb.
Maybe he meant 225/55R16205/55 R16 isn't an appropriate replacement for 205/65 R15 as
they aren't same circumference. Both 205/60R16 and 205/65 R15.
However, if both sizes are used or suggested by the manufacturer
they certainly suggested tire pressures for respective sizes. Follow
the car manufacturer.
OP should provide ALL relevant spec incl load rating.

Yup, needs 3 psi to get the same load carrying capacity.A standard load 205/65R15 is a 94 rating. A standard load 205/55R16 is a 91.
Were do you come up with this stuff? You don't even know the brand or model of tire.A standard load 205/65R15 is a 94 rating. A standard load 205/55R16 is a 91.

You don't need the brand or model. Ya' see, tires are standardized.Were do you come up with this stuff? You don't even know the brand or model of tire.
Well, I looked up those two different sizes for similar tires and they are BOTH load rated 94, 205/65/15: https://www.tirerack.com/tires/tire...65TR5WCO&vehicleSearch=false&fromCompare1=yes and 205/55/16: https://www.tirerack.com/tires/tire...HR6WCUXL&vehicleSearch=false&fromCompare1=yes Only the speed rating is different.I don’t need to know the brand or model because it doesn’t matter for load rating. Size does, and whether or not it is an extra load construction. Perhaps as Roofless mentioned he meant 225/55R16. That would be the appropriate size and load rating.
