Bart - all Dunlop race tyres have been tubeless for quite a few years although your wire wheels may not be. I am guessing that your tyres are 500x15 R5's as they are designed for rims from 3" to 5". Goodyear/Dunlop have an office in Diegem, Brussels and if you contact them there I am sure that someone will put you in touch with a local supplier. Alternatively, you can contact Jean-Felix Bazelin at Dunlop Motorport in Birmingham +44 121 306 7031/7074 (tell him the Morgan owning Scotsman put you in touch!) he will find someone to guide you. Before I retired, Dunlop Motorsport was part of the portfolio of manufacturing operations I was responsible for.
