I had a new tyre fitted and when I got home to check with "pencil type" guage it showed 25psi. I did a check because the steering did feel a little unusual. My bike needs 32psi.
So I've been back to the dealer who were very helpful
they did work on the tyre and upon return I whipped out my pencil tyre
pressure guage in front of the manager, I asked "what the tyre was
inflated to?" he say 32 psi, I did the test and it was 37psi
So he went into his shop and brought out a new tyre guage (£16) did the same test, it read 37psi So he went and got his "calibrated" gauge (£100 unit) and did a test, that showed 32psi.
So two cheapies indicate 37psi and the calibrated shop guage reads 37psi.
The dealer was very helpful so no complaints there at all. But I am at a loss to know which guage to believe, any suggestions would be helpful.
