Generally, no, you should not tint the windows on a rental car without explicit written permission from the rental company. Doing so is almost always a violation of your rental agreement and can result in significant fees, charges for full window tint removal, or even voiding your damage waiver. The primary reasons are contractual, legal, and practical. Rental car contracts strictly prohibit any alterations or modifications to the vehicle. Window tinting is considered a permanent modification, even if you use a temporary film. Furthermore, window tint laws vary significantly by state, and a rental company cannot guarantee that your DIY tint job will comply with local regulations, potentially leading to legal trouble for you and liability for them.
The financial risks are substantial. If you apply a tint and the rental company discovers it upon return, they will charge you for its professional removal. This process is labor-intensive and expensive. The cost could easily run between $200 to $500 or more, as they must restore the vehicle to its original condition. In severe cases, they might charge a "vehicle out-of-service" fee for the days the car is unusable while being repaired.
A safer alternative is to inquire with the rental company directly. Some larger rental agencies may offer pre-tinted vehicles or, in rare cases, grant permission for professional installation if you provide documentation. However, this is the exception, not the rule. For a temporary solution, consider using static-cling sun shades that can be easily applied and removed without leaving residue.

VLT (Visible Light Transmission) is the percentage of visible light that passes through the window. A lower percentage means a darker tint.
