Dakar and Sertao Tyres
There was discussion of what tyres were available from manufacturers for the Dakar. The list here covers
the standard tyre diameter and sizes. It has some basic info on studs. The list is a good one to build on.
The Don Coyote definitve tyre list, E and O E as always folks.
Heavy Duty Tubes
The tubes sold as "heavy Duty" are variable in both the thickness of the tube and the materials used to the point
it is very difficult to compare brands. The only thing which can be said is to check specifications and choose carefully.
