Tyre pressure

I've just bought a floor pump (giyo) and it has a pressure meter which tells me my tyres are at 30psi (30-50 recommended) but it feels really hard at 30 and I'm afraid to go any further. Is there a rule of thumb to stop me from bursting the tyre?

Thanks in advance!

    I doubt you'll blow them up, but you could try another pressure gauge.

    Most people overestimate pressure when using the 'thumb' test, they probably are at 30psi.

    Simple guide is too high and you get shaken around, lose grip and get more punctures.
    Too low and the bikes handling becomes very unstable, tyres can come off the rims and again more punctures.

    Gauges on pumps can be extremely inaccurate (mine is 12psi out).
    As above, you won't burst it and people tend to overestimate pressure when they squeeze the tyre by hand.
