The other day I inflated my tires up to 34psi and then when I took one of them off the car. I measured the pressure again to check how much the difference was, and I was surprised that it was still 34 psi.
What I suppose is that when the tire is put on the car, all the weight of the car is making pressure on the tires, so the pressure should "be higher" compared to when the tire is out. Is that wrong?
I tried this because I was wondering if the spare tire should have the same pressure or maybe less/more. So, should the spare tire have also the same pressure?
What am I missing here?
