too about 40psi, is this right?
Given the quality of the roads we will be using, 40 psi is about right
Some petrol stations have fancy digital pumps which are not high pressure, but most will get you to 70 or 80 psi or more, IIRC. It depends how they set it.
Sorry TerryP, but WA country roads surfaces are not smooth, and you'd need to be very tough or masochistic to run 120psi (800kPa?) on a long ride.
After a few hours of pounding from the chunky blue-metal, those 50mm Conti touring tyres look very attractive, and will run on 40psi if needed.
