During extreme weather conditions, Washington state does require chains, even on all-wheel and four-wheel drive vehicles, as noted above. In addition, Mount Rainier's roads are unlike most of Washington's in a variety of ways. At 5,400 feet above sea level Paradise is significantly higher in elevation than most of Washington's highway passes and roads. Furthermore, Mount Rainier's roads are scenic park access roads and are not intended to be as wide or have as many safety pullouts as a state highway.
