"Why make the 96 percent of the people who don’t use studded tires pay for the damage caused by the 4 percent of the drivers who do?"

The same question can be asked of Lane Transit District buses destroying our urban streets and paying absolutely nothing for repairs.  LTD buses carry more weight per tire than an 80,000 lb 18 wheeler.... over 4,500 lbs per tire.

At least the 18 wheelers pay weight/mile tax and fuel tax.  LTD pays nothing.
