Good point. However, my ORIGINAL tires were 'Firestone' (just a label;
they
don't make little tires like these) with STUDS! When I replaced, I could
not
even find a tire that would take studs. I would have used either ceramic
studs
(not serious wear to your driveway) or as I have seen ice-racers use;
short
machine screws in each hole. The screws have the advantage that you
can take them out for summer. The problem was that I couldn't find tires
with stud holes. Any suggestions?
;How much additional diameter can be fit in the well, enough to give
;any significant increase in the tire contact patch size?
You could modify or remove part of the fenders. Really, the different
height
is for clearance and for soft earth, not snow plowing. Yes, you could
also
change the pully(s) and belt(s) to preserve the same ground speeds and
torques. The CG will move up significantly, and you will probably do sod
damage when you use the machine in summer. You also might need to
put bigger tires on the front. A lot of work. BTW, there is about 1" of
axle/hub
adjustment in addition to the rim flip, at least on mine.
;If you're interested in better winter performance, would decreasing
;the width help by increasing lb/sq-inch on the contact patch?
For winter, yes. But give me my studs any day.
