bicycle tyre pressure ?

[fi_fi_suzy]

The tread reads 40-65 psi, however I have pumped it up to 30 and the tyre is very "tight". I fear pumping any more will blow the tube. Any thoughts/suggestions ?

Your gage may be wrong, try another one. At 30 lbs the tire sidewall will feel soft. You should be able to press on the side wall with your thumb and it should give a little, at 65 lbs it will feel pretty hard.

tubes do not have a separate max pressure rating

they are held back by the tire, which has a max

30psi doesn;t usually feel very hard

so your gauge may be off

pump it so it doesn;t bulge much when you are seated, riding
