    '15 Persona, should I keep the tire pressure higher during winter? I normally keep it at 33 front 32 rear, like the sticker on the door shows.

    They say more air in tire sheds snow better. Just sayin...

    These are the 215/45R17's? I tend to stay closer to the sticker recommendation with our 17", around 36'ish at the most, higher with our snow tires in 195/65R15, around 40. Running the 17's higher I find the ride too harsh. And little or no improvement in mpg.

    Keep your tire pressures where you want them, factory specs are ok, it's just that in winter tire pressures decrease because of the cold, so just keep them reading at the level you want.
