Tire Pressures ( Road bike )

The bit on the side of the tyre is written by the legal department. 8 bar (approx 120psi) is good. I often go up to 8.5 bar on the back for racing.

Is the harder the tire, the less likly you will get a flat tire ?

theoretically, supposedly. avoids the snake-bite puncture, but bites you in the [censored] instead :-)

My BS told me to keep tyres at 120PSi, however the tite reads max 100PSi.

Is 120PSi ok, or will it be too hard

Firstly if you over inflate your tyres you will end up getting the following problems.(Usually)
1/ Any rough surfaced road will give you increased bounce on the tyre and reduced performance while wearing out the trye at an amazing rate.
2/ Anything you hit with the tyre will increase the possibility of blowing a tyre. However underinflation will increase the risk of snakebite flats(Where the rim hits both sides of the tube and flattens it)
3/ If you start out with the tyre too hard on a hot day, the end result after the trye warms up is well above the optimum for performance and any tyre being used outside of it's optimum pressures will eventually fail, sometimes quite dramatically.
4/ The recommended tyre pressure is the common denominator between performance and wear. If you are big and heavy, or little and light the need to alter the tyre pressuers is at best mimimal.
If you are going to alter tyre pressures at all, it is best discussed with the local club racers and they usually alter them for a specific reason and for a particular application.
Hope this helps

Use the rating on the tyre with *perhaps* +5-10 psi, if you're confident that is.
