if you're getting punctures all the time then your tyre tread must have worn down and time for new tyres.over autumn/winter i seemed to get punctures almost every single time i went out, the tyres were afew years old from riding almost daily 2-3miles. eventually bought a new pair in feb and haven't had a single puncture since.
I'm with okgo on this one.
Get your tyre pressures right, and then check them regularly. Learn to make full advantage of your four-point fully independent multi link suspension (arms and legs
) and unweight the bike over bumps, small potholes and rougher surfaces. Learn to 'hop' the bike over bigger obstacles.
FWIW I run 700 x 25c Continental GP4000 S II on my Trek Emonda. I inflate them to 90psi front, and 100 psi rear, and they stand up OK to a right beating over some local MOD training area gravel roads, and even the odd Strava segment that'd be better ridden on a MTB.
The right pressure for you will be different to someone else, as bike + rider weight, tyre width, and terrain will all have a bearing on the perfect psi. So look for advice online (there are charts I've used from magazine tests, especially German technical reviews that you can search for) and set a ballpark baseline figure, then increase/reduce pressure until you find the sweet spot. Then just mark it on a pump with a pressure gauge and check it regularly.

Tyre pressures I would suggest.
Rookie mistake I'm afraid. Get a track pump so that you can be sure of getting the pressures correct, I did this about 5 years ago after getting numerous flats and realised that I was only putting about 85 psi in my Conti's that are recommended for 110-120. Stopped the problem straight away,
Also consider a Kevlar based tape product from Panaracer (Wiggle sell this), that goes inside the tyre between the inside face of the tyre and the innertube. This will stop a lot of incomming stuff and although I'm probably damming myself in the process, I've done around 30 Sportives since without getting a puncture!!

I run 120 psi on both with my Conti GP4000S ii.....as stated on the sidewalls. No problems with punctures.g7jhp said:

23/25c will play a huge difference there in pressure. Also what is stated on the sidewall is likely max, not what you SHOULD or HAVE to do.120psi is generally too much for 23c and far too much for a 25c
As others have said - make sure there is enough pressure (but not too much) in your tyres. Rookie mistake is to have them underinflated which can lead to punctures (basically, an under-inflated tyre envelops the sharp object whereas a well-inflated tyre will ping it away). Plenty of charts on the internet explaining the right pressures for your weight, tyre size, riding, etc.
Also, if you are regularly getting punctures, make sure you have fixed the previous one properly. The sharp object might still be in the tyre waiting to give you another puncture.
Unless you have done a lot of riding (a few thousand miles), I wouldn't expect it to be worn out tyres that is causing the problem.
