Tire Inflation Question

cant answer your question, but I did pickup an awesome Topeak 'JoeBlow'
floor pump with a pressure guage two weeks ago from my LBS on Bridge Rd in
Richmond, about $65 from memory with my BV discount 🙂 cant see how I ever
lived without it..

On my road bike, I like to keep my tyres at 120psi.

My 2 questions are .
How long will this pressure last before it starts to go down.

How often should I check the pressure, as I notice if I don't ride for a
long time, they do go down a little, am I correct ?

Pump them to 120psi and then squeeze tyres with your hands to get an
idea of how hard they are. Test them every time you get on the bike
with a quick squeeze. I know this isn't super accurate, but it's quick and
it'll give you a good idea if you need more air or not.
Otherwise get a pressure gauge and test them every now and then to see
for yourself how fast they go down - then pump appropriately.

I run 23mm road tyres around 110psi and find they are normally down to about 100 after a week and about 90 after three weeks. I'm currently using Bontrager RaceXLite tubes (IIRC). Hippy's advice on squeezing the tyres is spot on.

PS. My own rule of thumb is to ride the bike. As the tyre slowly deflates, the ride feels smoother over small bumps and more ... (searching for ideal description...) squishy(?) when climbing out of the saddle = time to reflate.

With less effort, you can just tap the tyre. At high pressure it'll
resonate with a certain pitch, like a spoke - when the pitch drops much,
or it doesn't resonate at all, it needs pumping up.
