Tire pressure on new bike I have the new Tommaso (was Timmaso) Imola bike with Tommaso Corsa TC20 wheels.  The tire sidewall says "max pressure 90 psi" 

The tire is the kenda 700x25c.

I am 5'9" 220 used to be a power-lifter so pretty heavy. Question is can I inflate them to closer to 120 psi due to my weight?
This handy chart shows the recommended pressure for different rider weights.
Sadly it doesn't help you or me, both our weights are off the chart.

My road bike has 700x25 tyres, so I picked 100 PSI and aim for just over that when inflating.  The tyres are rated to 120 but that feels harsh and I get a lot more flats at those pressures.

Added: Since your tyres say maximum pressure of 90 PSI, you shouldn't go much over that.  Kenda's specs say 90 psi is the maximum for the "kenda street black mocha" so while they will survive more, the question is how much more.  Instead, consider replacing them with tyres that are suitable for higher pressures.



Note: This chart is purely referencing road tyre pressures.  If you have a MTB the pressures drop off really quickly.

Answer: I wouldn't go much over 90 PSI, but others have routinely put 100 PSI in Kenda tyres without issue.  Your weight suggests that a higher max-pressure tyre would be the best solution, aim for 120 PSI capable tyres in 28 width.
