Tires, new Nitto Motivos..problems

Tried increasing pressure from 35 to 40 then 45 and no change....had alignment checked prior to tire change and was perfect...maybe needs changed with new tires?

I am perplexed as to what the issue is,,,,are the tires just not the right ones to have on a Z, or should I go to 50 pounds??

I hope someone has some ideas as I will need to return the tires and replace with something else in the next day or two.

thanks for your help.
