The foam tires won't make the plane 'bounce', they usually help absorb the 'impact' rather than bouncing like a ball on a hard surface. The landing gear is typically the culprit for causing the bounce if you drop one in a little hard, or are too hot on landing. And, if the gear is flexible/springy, that also contributes to the problem. I have found stiffer gear can make landings a little easier with less bounce/rebound. Kind of like a pole vaulter using a steel or stiff pole vs a very flexible pole. The flexible pole will bend further and help him clear a higher bar as it 'snaps' back to straight.
