What are tire chains and cables?

Tire chains and cables are devices that improve traction in snow and ice.

You can purchase chains or cables at most auto parts stores and gas stations, particularly in communities surrounding Yosemite National Park. A limited selection of chains is available for purchase at the Village Garage in Yosemite Valley and the Wawona gas station. Be sure to purchase chains or cables that match your tire size.

It's difficult to find businesses that rent chains; they're usually only available for purchase.

Chains provide better traction than cables, however cables are easier to install; both are acceptable under the law. Your vehicle's owner's manual may specify that you use cables, not chains.

Is it likely that I will need chains?

If you are visiting from November through March, you should expect chain requirements to be in effect (though it's possible you may not need to use chains), even if you only plan to visit Yosemite Valley and use the shuttle bus. Any time chain controls are in effect, all vehicles must have chains in possession, including four-wheel drive and rental vehicles.

Chains are often required on park roads from November through March, less often in October and April, and rarely in September or May. Because higher elevation roads receive more snow, chains are required on the Wawona Road (Highway 41), Big Oak Flat Road (Highway 120 west), and Badger Pass Road more often than on the El Portal Road (Highway 140), roads within Yosemite Valley, and the Hetch Hetchy Road.
