hi there if your rim is a conventional spoked rim ie spokes going through it and you can see them under the rim tape you will have to use a tube. you can use a tubeless tyre on a tube type rim but with a tube fitted , with old road bikes it is hard to find tube type tyres now so you just fit tubeless with a tube, to stop air seeping out through spokes , they are just a little more difficult to fit . some spoked rims the spokes dont go through the rims so are prosumably are made for tubeless tyres and should be marked tubeless type .but please note do not fit tube type to a tubeless rim it will not make a seal on the rim . so unless some one has come up with a way of sealing spoke ends you need a tube . take care zigzag
