Tire Chains for Tahoe: What to Buy and When You'll Need Them
Chain control can end a ski day at a checkpoint. What chains are for, where controls commonly go up on I-80 and US-50, and how to check before you drive.
When a storm sits over the Sierra, Caltrans can impose chain control on I-80 and US-50 with very little warning. At a control point, traffic stops and vehicles that do not meet the posted requirement get turned around. Your reservation, your lesson booking, and the lift ticket already on your phone do not enter into it. What is required varies by storm and by vehicle, and the requirement in force is posted at the control itself.
That is the whole argument for the pair of chains on our packing list at /gear. They spend most of the season in the trunk doing nothing, and then one Friday night they are the difference between skiing and driving home.
Where controls commonly go up
These are the areas along each corridor where chain control is commonly enforced in winter. They are not a live status, and not a promise about where you will be stopped on any given day.
- I-80 over Donner Summit: Kingvale is the common checkpoint. If it is snowing on the summit, plan on chains going on somewhere around there.
- US-50: Twin Bridges, near Strawberry, is the common control area on the climb toward the south shore.
- Caltrans QuickMap (quickmap.dot.ca.gov) is the source of truth for what is actually in effect right now. Check it before you leave, and again before you commit to the drive home.
Buying a set
Chains are sold to fit a specific tire size, so read the numbers off your sidewall before you order anything, and check what your vehicle's own manual says it can accept. A set that does not fit is the same as no set at all, and you will find that out in the worst possible place.
Our two picks are on /gear. The Security Chain Super Z6 is GearJunkie's go-to passenger chain: a low-clearance Z-cable design with built-in tensioners, so there is no re-tightening stop after you get moving. The Konig CB-12 is the time-tested budget classic, a heavy-duty design built for the snowiest climates.
Throw a headlamp and a pair of work gloves in with them. Installing chains means kneeling in slush, in the dark, in traffic, and you will not want to do it in your ski gloves.
The other thing in the trunk
A folding snow shovel is on the same trigger as the chains, and it is not there for avalanches. It is there for the berm the plow left across the end of your parking spot while you were skiing, for the two feet of fresh sitting on your car after a storm day, and for the wheel that spun itself into a hole at a trailhead lot. Our pick is the Black Diamond Deploy 3, the backcountry standard, which deploys fast and packs flat in a trunk.
Chain control questions
Do I need chains if I have all-wheel drive?
Sometimes. It depends on what level of control is in effect and on what is posted at the checkpoint that day, and that changes storm to storm. Carrying a set that fits your tires is the only way to make the answer stop mattering.
Can I just buy them on the way up?
You can try. Stock near the passes may or may not be there when everyone needs it at once, and you will be choosing under pressure instead of choosing correctly. Buy them at home, in your size, before you need them.
How do I know whether control is up right now?
Caltrans QuickMap. Not a weather app, not a webcam, not something a friend posted this morning. Conditions on I-80 can change over the course of a single afternoon.
What if controls go up while I am at the resort?
The same rules apply in both directions, which is why the chains stay in the trunk for the whole trip rather than coming out once you have parked.
