I finally checked my tire pressure with a gauge (vs the gauge on my compressor tool which has been ran over by a car...). My tires were at ~27 psi.
I had filled them up when I got the car, apparently not enough. I must have slow leaks so I'll have to keep an eye on it. The tires are VERY weather checked and cracked. I'll need new ones before the snow flies. The tread is low but not horrible and the car actually did quite well through the winter. I was surprised by the traction I had. Anyway, they all have 55 psi in them now and woo it makes a difference!
