I actually just picked up an Electra Cruiser 1 in Matte Bark today. It was too good of a deal to miss. So now I'm looking for two sets of cruiser tires, one for the Giant CFM-4 and the other for the Cruiser 1. After a bunch of reading and the great advice here, I'm leaning towards some tan Maxxis DTH 26 x 2.3 tires on the Cruiser 1. Still unsure on the CFM-1. Maybe the DTHs in black or the Continental Contact Cruisers as the CFM-4 is black carbon fiber.
Thanks again for the replies everyone.
