What's the best tire/tire interface on a two wheeler?
I've heard a Semcycle engineer say that the bottom tyre should be at 'regular' pressure to support the weight, and the top tyre should be softer so that it folds around the bottom tyre. That should help to avoid that the tyres 'run off' each other.
If slip occurs while the tyres still track right and you can't bring them closer (are any twowheelers adjustable in this respect?) you would have to increase the top tyre's pressure.
