Air pressure confusion?

[Eddie_1]

Recently I bought a new tyre and inner tube since my old one has a massive tear,
my old inner tube 700x23c said to raise pressure to 100 psi to 110 psi
my new inner tube is a 700c x18-28, so my question is that do i raise the pressure to the same (100-110psi) to get it to fit to 23mm or is it different also my new tyre says 80-140psi

I would just inflate the tube to somewhere in the range written on the outside of the tyre that you are matching it to.

100 to 110 is ideal for 23mm. I go 110 on rear with panniers.

I always go 120 but im heavy so just play around with it until you find what you like, take not of the tyre not the tube

As slowmotion says I would always pump the tube up to a pressure indicated on the tyre you're matching it with. I always go between 80 and 100 PSI

So long as your tube fits the tyre then go with the PSI recommendation on the tyre.
I made the mistake the other day of not noticing that the new folding tyre I'd bought was 100 PSI max, so happily stuck in my usual 120 and was very surprised when the tyre bulged out and exploded.
