I'm not sure how picky these forums are so if I am not following proper protocol, please let me know. I have a 1985 World Sport with the Schwinn HP sport 27 inch by 1.25 tires. The bicycle is all original from the tires to the seat and I am the original owner. I don't really know a whole lot about bikes since I am just a novice and I got the bike as a gift. My question is the tires, I've Googled to find replacement tires and with the bike being 26 years old, I cannot find anyone who sells the original type tires. What would be a good replacement road tire for the bike? I don't ride it every week, just every now and then, but that could change to at least once a week if I made more time for cycling. The purpose of getting back into riding is to lose weight. =0)
