I'm wondering if you should be looking at knobbly bike tyres. Pick something you can easily find locally should you need a spare or two. Are there particular regulations you need to follow either to be road legal or for the events? Anyone know what tyres were used by this pair? https://www.telegraph.co.uk/motoring/274...egins.html
