Another tire question

Can a wider tire be run on front wheel? Say 100/90-21. Anyone try this?? Does a 140/80-17 work
on the rear with some makes of tire

Yes you may easily run wider on the front.

But one really doesn't gain much on the rear. Why?

Because the rear wheel rim is already 1 size narrower than ideal for the 130 width tire. When a 140 is installed it is squeezed even 'rounder' in its profile. So it really doesn't lay down any larger footprint. Does this make sense?

The 140 may or may not rub on the inside of the plastic chain guard.

Thank you, makes perfect sense. Does that hold true for the front as well?

Not by enough to matter much on the front rim & tire combo.
