Wheel/tire size?

If I go to a 15 inch wheel for the track, will that be the equivalent of going to a lower gearing?

Also, is it total wheel/tire diameter that affects this? In other words, if I went to a lower profile 16 inch tire that gave the same total diameter as a 15 inch wheel with a higher profile tire, would it be the same "gearing" effect?

Thanks
Scott

Yup. Overall diameter is what counts.

Actually what really counts is the loaded rolling radius of the tire. A tire on the road is no longer circular. Most manufacturers provide this info

the revs per mile is almost as good, but slightly less useful
