I have the H1's front and back. The ride was VERY comparable to Peewog's OEM setup, and she has about 75k miles on them. Tire size is one factor in the quality of the ride, but different tires are going give different rides due to differences in sidewall stiffness.
Transio, when it comes to suspensions, I know that designers try to keep "unsprung weight" (meaning the weight of the tires, wheels, hubs, brakes, and suspension linkages) to a minimum, because the more weight you have bouncing around under the springs, the more energy gets transfered to the chassis. Having "heavy wheels" therefore will make the ride worse. Lighter wheels will shake the car less.
