The 'cush' factor...

The 'cush' factor--how cushy a ride a tire will give--is a function of tire size, width and pressure. Mechanically, physically a bigger rim/tire affords a greater angle of attack, smoothing out bumps. But cush will be eroded if it is running a narrow tire at high pressure. Bigger rim size is mot always cushier. An example is my 406er running 42mm-wide tires vs. my 451er running 37mm tires. The former is still cushier, despite being smaller. Why? Because the 42mm tire is not only wider, but also has a higher profile, and, due to that, it can be run at lower pressure. So, it's not as simple as chosing the larger rim size.
