my bicycle tyres are marked showing that they can be pumped up to a pressure of between 50-75 psi. I usually pump them to 60 psi (roughly middle of the range because I don't know what the range is for.)
i ride mainly on the road. what pressure should I use?
pump your tyres up to the higher pressure for road use.the lowest pressure for off road.
I can help ...
If my bicycle tyres - 50-70psi?
