If you get wheels or tires that need a different pressure you have a few options. I have used a sticker in the glove box, open the glove box and put a sticker on the inside of the part that opens. Those temporary name stickers from an office supply store work, just write the info on the sticker with a marker. I would not cover up the factory sticker because you may want to go back to the original setup or sell the car at some later date and keep the aftermarket wheels or sell them separately.
