Hello I have a Knights Cycle, see images attached. I believe the bike was made around 1982, some 38 years ago. I purchased the bike from the father in law of a good friend some 33 years ago and the tyres are the same as when I purchased it. I think they therefore need renewing. Can anyone help me with this please. I understand the tyres are know as Tubs and from the image they have a yellow patch stating Liontyres GT 30 (or50 or 80); there is also a badge on the wheel rim stating Super Competition Champion Made in France. I'm really not sure where to start and the wheel rim measure around 24" dia (ie side to side); what size therefore are the wheels?
I have consulted a very well respected bicycle mechanic, but he does not go back this far and has no experience with this sort of tyre. Can anyone also recommend a good video or any instructions to enable me to fit such a tyre, when I can establish which tyre I need to purchase and where such tyres can indeed be purchased from.
I am also considering if it would be viable to have the wheels re-built, because some of the spokes are a little rusty?
Any help and assistance would be very much appreciated.
