I'm riding a 1999 FLHR and am for the first time buying a rear tire myself and not through my dealer. My INDY shop closed this year and I'm on my own ordering through the WWW. The tire that's on it is a Dunlop MT90B16 MC 74H D402 white wide sidewall. There is the word TUBELESS on the tire. I have spoked rims. My question is...I thought with spoked rims a tube was required. Do I need to order just the tire or tire and tube? Sorry for the newbie question, and thanks for the help in advance.
