If I remember correctly, OSHA requires a heavy duty tire cage for any inflation pressure greater than 100 PSI. So, if they don't have a tire cage, then they can only inflate "light duty tires". The shop foreman had probably drilled 90PSI into their heads so much they thought they'd get shot or worse if they adjusted a regulator to get you where your tires needed to be.

I hadn't thought of that. I don't remember if they had a cage or not. I was a bit stressed out. I used my DeWalt 20volt air compressor to take them up to 125psi.
Otherwise I'm a long time fan of Discount Tire.
