Visual check:do not ignore the little breach. When we check the pressure of the TBB tyre, we can check whether there are sharp object which can break the TBB tyres. The little opening can also bring the huge loss.
Check the wear style of the tyre face. Overmuch tyre wear can indicate the under-inflation of the tyres, while the wear of the central part can indicate the over pressure of the tyres.
Tips: many tyres has a triangle mark on the tyre. If the wear degree of the tyre face is close with the rubber block, it means that the tyre needs to be replaced.
Avoiding the over pressure and under-inflation is of the same importance. Check it regularly to ensure the tyre safety.
