Not sure if you need more than the 32ish psi that's stated, even for larger tires (I could be wrong). I don't think the tpms goes off until the pressure reaches something over 40psi (I've hit 40 or 41 without anything going off before). As far as I'm aware, the dealer can only reset the speedometer for 28" tires. Mine wanted $75 to reflash after I got my new tires. Didn't do it. I just know to add a couple mph to what the speedometer says.
