It's tread compound that makes the biggest difference. For practical purposes, deflection is pretty close to the same for all tires in a given size.
Also, the part of the mass that is important is the tread - and that doesn't vary a lot for new tires within a given size.
But the properties of the tread compound vary wildly.
And to put this in perspective, differences between sizes is small compared to the differences between makes and models of tires.
