Sure they do but by construction, long reach caliper brakes have a lot 
of internal losses. The bike builder decides which version of caliper 
brake he puts on the bike, and the consumer has to live with the 
restriction (only narrow rides, no mudguards etc).

With V-brakes, drum brakes or disk brakes, brake clearance does not have 
an influence on possible tire widths.
