All else being equal* will a bigger tire handle road imperfections better? The idea is that road imperfections will seem 'smaller.'
Imagine a giant tire going over a pothole mostly undisturbed but a smaller tire may well be swallowed up.
Practically speaking, your larger tire will most likely have more sidewall, be wider, it will likely also add more rotational unsprung weight and be further away from the axis which hurts braking and acceleration and be tougher on your suspension system to handle, you will be limited by the size of the wheel well. Practically speaking, you might get away with adding an inch or two of extra rolling diameter in your tires. Hypothetically speaking though, it seems like your bigger tire will handle road imperfections better, even assuming that the sidewall remains the same (because you're using a larger wheel) and the unsprung weight remains the same (because your larger wheels are made of carbon fiber, let's say...)
Thoughts?
