"Pretty expensive"?"
I sent my wife to get that done, but I'm afraid she messed up.
The winter replacement stuff is also the most EXPANSIVE.
So the wintertime air should keep those tires at correct pressure.
But the next day after she got the air changed, the tires were low.
She must have told what she wanted, and they heard her to say
"expensive" instead, so they gypped the woman like they always
do. But she still gets the "pretty" part right.

Take it to an air dealer. *You might pay a little more, but you know you
