Older rims, newer tires Can I put "new" 27 and half inch tires on "old" 27 inch rims?  Looking to 
save the trouble of finding out!
Have not seen 27 x 1/2 tires before but the old 27 x 1 1/4 rim probably will not care if the width is greater.  One question is whether the wider tire will clear your frame.
