The Silca pumps are great quality pumps especially for high pressure road
tires, but the volume per stroke is rather low compared many other pumps.
For a mountain bike it isn't a big deal, but I wouldn't want to inflate
a car tire with it.

The best bicycle pump for inflating car tires would be the one with the
largest diameter barrel and longest stroke. The blackburn TPS-1 has a
pretty big barrel and stroke. So much so, that it is difficult to inflate
road bike tires with it. Maybe blackburn has resigned the double sided
schrader/presta head, but a problem I had a few years ago was the schrader
head had a check valve built into it which severly constricted the flow
of air to the tire. It considerably raised the effort needed to inflate
the tire.

For both bike and car tires, it is hard to beat the Zefal double shot. One
drawback is that the body is made out of plastic, so you have to be carefull
with it. I've had mine for about 10 years now and it still works well.
11 pumps on a 700X23 and I am just over 100psi. 50 pumps or so and I can
get a 195/50X15 tire up to 35psi from flat.
