Yes, you can generally install snow chains on a Hertz rental car, but only under specific conditions and with prior written authorization. The core rule is that chains must be used in accordance with state laws, typically only when required by authorities due to severe weather. Installing them without checking Hertz's policy first can lead to damage fees for any scratches or harm to the wheel wells, brakes, or chassis.
Hertz's official policy, detailed in the rental agreement, is the ultimate authority. You must contact the specific rental location directly before your trip to get permission. Policies can vary by state and even by individual branch manager. For example, locations in mountainous regions like Colorado or California's Sierra Nevada may be more accommodating than a branch in a primarily urban area.
When you call, ask these specific questions:
Choosing the right equipment is critical. You must use low-profile, SAE Class "S" cable-type chains, which are designed to fit modern vehicles with minimal clearance. Traditional link chains are often prohibited as they can cause significant damage. You are responsible for purchasing, correctly installing, and removing the chains. Improper installation is a common cause of damage.
The following table outlines key considerations based on Hertz's general policies and common U.S. state regulations:
| Consideration | Details | Rationale |
|---|---|---|
| Authorization Required | Must obtain prior written approval from Hertz. | Violating the rental agreement can void damage waivers. |
| Chain Type | Low-profile SAE Class "S" cable chains are typically required. | Prevents damage to brake lines, chassis components, and wheel wells. |
| State Law Compliance | Chains are only to be used when mandatory (e.g., "Chain Control" signs). | Using chains on bare pavement is illegal in many states and causes rapid wear. |
| Liability for Damage | Renter is fully liable for any damage caused by chains. | Includes scratches, torn brake lines, or damage to the vehicle's undercarriage. |
| Vehicle Restrictions | Not all vehicles are approved; often depends on tire and wheel well clearance. | Sports cars, low-profile luxury sedans, and some sports utility vehicles may be prohibited. |
Ultimately, planning is everything. If you anticipate needing chains, the safest bet is to rent a 4WD or AWD vehicle equipped with winter tires, which often negates the legal requirement for chains in many states and is a much safer option.

My family and I learned this the hard way on a ski trip to Lake Tahoe. We just assumed it was okay. Big mistake. We got the authorization from Hertz, but we didn't realize our rental had those fancy alloy wheels. The chains scraped them up pretty bad, and Hertz charged us a few hundred dollars for the refinishing. My advice? Get permission in writing, and then double-check that the chains you buy are the correct, low-profile cable type for your specific wheels. Don't just guess.

As someone who rents cars frequently for work in the Rockies, I always check the policy. It's not a simple yes or no. Call the specific Hertz location. Ask them: "Is my exact car model approved for chains?" Then, only use them when you see the "Chains Required" sign. Drive slowly, under 30 mph. The moment you're off the snow, pull over and take them off. Driving on bare pavement ruins the chains and the road. It's all about using the right tool for the right condition.

Honestly, I'd avoid chains on a rental if you can. The risk of damaging the car and getting hit with a huge fee is real. A much smarter move is to reserve a 4WD or AWD vehicle from the start. These vehicles often meet the traction requirements during chain-control stops without needing chains at all. It costs a bit more, but it's cheaper than a four-figure damage bill for a scratched-up wheel assembly. Check the rental confirmation email; it usually states the drivetrain.

It's all in the paperwork. Before you even leave the Hertz lot, open your rental agreement folder. Look for the section on "Prohibited Uses" or "Winter Driving." It will spell out the policy. If it's unclear, ask the agent to highlight it for you. Taking a photo of this policy with your phone is your best defense. If you later have a dispute about damage, you have proof of the agreed-upon rules. This小小的 step adds a layer of protection and ensures you are following Hertz's specific guidelines correctly.
