I switched from 40mm semi knobby tyres to 32mm slicks . Replaced the original tubes too, which were very heavy, with lighter road tubes. The difference for commuting was wonderful.I could go about 15%-18% faster or the same speed with 15%-18% less effort(at normal 20-25kph speeds). Really noticeable into a head wind or up a slight grade.Should have done it ...
Or you can go smaller and shim it up with aluminum cans. EDIT: I removed the suggestion to get a 27.2 and remove .2 mm of material.
