Contradicting tire pressure

[novetan]

Currently am using Vittoria Zaffiro tire. Yesterday I chanced upon a Vittoria tire pressure chart from a bike shop and then only I realized basing on my weight of 65kg, the pressure shld be bet 90 to 95 psi. But the imprint stated on the tire itself mentioned bet 100 to 120 psi. I still have a new box of the same tire and the instruction so clearly stated “never allow the pressure to be less or more than the indicated pressure”. For my case is already less.

So what is your advise. Shld I pump to the min. 100psi or follow the chart which is less than 100 psi.

It looks like it is the weight of the bike and the rider, not sure if you had also Included the bike. If not, it might move it to another PSI band.

Yup...

The tyre may be capable of holding 120psi but I'd agree with the recommended based on actual rider+bike weight. FWIW it puts me in the 95-100psi zone which through trial and error Ive found is the best for me.

So if you put on weight the tire pressure can go up.

Just pump the tires to what you want, but not over what the tire says.
