For a ~25mm wide rim, tires around 1.5" are about right.

The Schwalbe Marathon Plus is also another flat-resistant tire to consider, and it comes in 1.75" width, which is more reasonable on a typical ~25mm rim.

Spoken like someone with no experience on the tire in question.
What's the purpose of running low pressure at all on the street? It's flat pavement, not rooty singletrack...
