Since your model year should have the indirect TPS system...when you change the tires or add air etc...you should follow the simple instructions in the owners manual. No need to do multiple presses of the buttons...and even different sized tires should not prevent a reset because it is only resetting a base rotational setting. It's not like the ASC/DSC system that has preset rotational values:
{see initialization instructions from owners manual}
If the table below is what you saw...the instructions are to press the button for
5 seconds ...not 5 times. Which is the same instructions as written in STEP 2 in owners manual instructions above except the table below lists an actual time integer for pressing/holding the FTP button.
