Hi, could some of the more experienced out there solve a problem, I am relatively new to trials and I am having a problem with the inner tube creeping round inside the tyre. The tyre itself is not moving (paint marks) but after a short time the valve is at an angle as the inner tube is moving relative to the wheel and tyre. It only seems to happen with new tyres/tubes and after a while stops happening. I run 5 psi on a classic ie heavy bike.
Thanks
Jon
