Yellowstone park south entrance with chain tires???


I called the automated help line at yellowstone national park and it said that the south entrance required vehicles to have chains on the tire...is this true? We want to enter yellowstone tomorrow afternoon (30th May, 4 PM) through teh south entrance. Could anyone let me know if the chains are mandatory? Also we are driving in an SUV....will they let us in?

Thanks in advance,

Welcome to the high country! Here's the Wyoming law, especially the first paragraph.

The forecast suggests below freezing temps at night, warming during the day, so you probably will be OK. Call the "511" number for updates.

Road Closures

Sudden snowstorms can cause road closures. If you are traveling through Yellowstone, call 307-344-2117 for updates.

You should keep checking, but we entered through the South entrance the first day they opened...May 14 2010. They were still clearing the sides of the roads with equipment, but the roads were completely clear.

We just got back Sunday. There is snow everywhere along the south entrance, but not on the road. It snowed daily in the Canyon area. It was very scary with a quick, thick snow/sleet storm. Temps went from 50-20 in minutes. We didn't have chains on our suburban and were fine. They don't "require" it at the gate or anything, but they do shut down entire roadways.
