Reply to "Tires"

I have 5.5" rims on a VMC build with IRS.  The tire-to-rim convention I'm familiar with (on a much wider rims) is the tread width should be 1/2" less than rim width.  On these Speedster rims, that math means the tread-width (and tire) will be too narrow.

TireRack.com lists manufacturer specs which suggest a range of rim widths that work with various tire sizes and consistently states a 5-1/2" rim is the narrowest rim for a 195/60 application.  The Vredestein Sprint + in this size has a 7.7" section width and 6.2" tread width.  On the other hand, the Goodyear Eagle RSA has a 6.0" tread width...that's getter closer to a "balanced" sizing.  Two different looking tires, but same nominal size.

I bring this up because this defies my understanding of tire sizing, so I want to ask you what you're running, if you're happy or what would you do differently?  I've come to drink from the well of wisdom.
