I wouldn’t run over 120 on local roads. I’m not familiar with those specific tires. I’ve got tubulars that max out at 200 psi. Anything over 120 in them makes the ride quality bad. If you are racing, perhaps trading ride quality for less rolling resistance is worth it.
Check the maximum pressure for your wheels. Rims usually are limited in the low to mid 100s.
Unless your local roads are unusually smooth, 150psi is not only harsh but slower as well. Overinflated tires don’t conform to the road surface and actually increase rolling resistance.
Perry Moarman, HTC team mechanic, said that normally the team will inflate to 8.0 bar (116 psi).
Pros are running under 120psi (on tubulars, no doubt). The correct pressure for you will depend on the tire, your weight, and what your local road surfaces are like. But 150 is almost certainly excessively high.
I use Zaffiros, too, and prefer to pump them about as hard as they will go.
Do what is comfy for you within the inflation range of the tire. But don’t overinflate it to get it to the max pressure. You’re not doing the tire any favors.
They may go to eleven, but I prefer it more around eight. More is not always better.
150 psi? word – That would result in a painfully harsh ride for me. I have 23mm Vitorria’s Open Corsa CX-somethings on one of my road bikes and usually ran 110-120 psi, 95-105 is still more comfortable and not noticably slower. See #2 and #4 above for other very good reasons.
