All tpms sensor will go off when 1 or more of your tires go under 25% or more of the recommended psi. You will also set them off if the tire pressure is too high i'd say for the versa around 45 is way too much. As for tire wear, if u have too much psi tires tend to wear more in the center and setting it too low will make the tire wear more on the shoulder or outside of the tread. Obviously its best to have it set at the recommended psi to promote even wear. And finally u should check ur air pressure at least once a month and asap after there is a big change in the temperature. Going from hot weather to cold the air in ur tire will compress and u will lose psi, vis versa for cold to hot weather as the air will expand in ur tires and maybe over recommended amount.

I speak out of experience. I've been a discount tire employee for over a year and a half now and I deal with stuff like this on the daily basis
