I have never had a pinch flat, always ran 15psi front and rear in WR and Beta and ran 22psi front and back on XT when adventure riding but traction was never great on any of them unless the tyres were new. WR & XT are on HD tubes just to be safe. Beta is standard tube front and Tu-Bliss on rear. Traction on a worn tyre with Tu-Bliss is way better than a new tyre with tube, thats what i have found. Others may have a different opinion.
