Actually weight is a factor but probably not the most critical, the tyre pressure/surface area and wheel spacing are very important.
Case in example Fighters will carve up a tarmac where a A310 wouldn't because of the fighters extremely high tyre pressure (Eg. Mirage) and its weight distributed on a very small tyre surface area. I will call my theory the"Stilletto Principal". Imagine a fat babe in sneakers verses the similarly hefty individual wearing stilletto's....the result on your foot when she steps on it whilst sharing that last dance will vary from BL**%#Y painfull to catastrophic.
