Side view mirror angles

[George Maz]

Is it just me, or do the side view mirrors offer no help when trying to park alongside a curb?

After spending nearly 6000 miles driving my ZR-1 I'm finally posting this very basic driving question. I really can't tell where my wheels are in relation to the curb when parking. Often it takes me several back and forth movements, and I'm still not sure where exactly I'm distanced. Pristine condition A-molds & Dymags, so I'll error on the side of caution...usually a foot away.
I've always set my mirrors outward, as I'm aware of the body of the car, and I'd rather have the extra wide angle view if something is closing in on my space... but there's just no adjustment that lets me see the rear wheels.
