There are many steps that can be taken. At the moment, car designs make absolutely no effort to minimize tire particulates. I could see some basic airflow changes, along with rough filters, that could vastly reduce rubber particulates. And the real issue isnt even the rubber but all the random chemical additives in that rubber. Some basic study and perhaps modification could also reduce impacts.
