Are 37 Inch Tires Legal?
The legality of 37-inch tires is a complex issue that depends on a combination of factors, including:
Vehicle Type and Regulations
Different vehicles have different tire size limitations set by the manufacturer and local regulations. Some states or provinces may have specific laws regarding tire size, especially for street-legal vehicles.

Federal Regulations
In the United States, there are no federal laws explicitly prohibiting the use of 37-inch tires on vehicles. However, certain federal regulations, such as those set by the National Highway Traffic Safety Administration (NHTSA), indirectly influence the legality of oversized tires. These regulations primarily focus on vehicle safety and emissions standards, which can be impacted by modifications like tire size changes.
Impact on Safety and Emissions
Larger tires can affect a vehicle’s handling, braking, and speedometer accuracy. It’s crucial to ensure that any tire size change doesn’t compromise these essential safety aspects. Additionally, oversized tires can potentially increase a vehicle’s fuel consumption and emissions, which may not comply with EPA regulations in some cases.
State and Local Laws
While federal regulations provide a general framework, individual states and localities may have their own specific laws and ordinances regarding tire size. Some states might impose restrictions on the maximum allowable tire diameter, while others may have regulations related to tire tread depth or type.
Researching Local Regulations
It’s essential to thoroughly research the tire size regulations in your state and local area before installing 37-inch tires on your vehicle. Contact your local Department of Motor Vehicles (DMV) or law enforcement agency for specific information and guidance.
Vehicle Manufacturer Specifications
Vehicle manufacturers typically provide recommended tire sizes for their vehicles, taking into account factors like suspension, brakes, and wheel wells. Installing tires that exceed the manufacturer’s specifications can void your vehicle’s warranty and potentially lead to safety issues.
Consulting the Owner’s Manual
Always refer to your vehicle’s owner’s manual for the recommended tire sizes. This document will outline the manufacturer’s guidelines and any potential limitations regarding tire modifications.
Insurance Considerations
Modifying your vehicle, including installing oversized tires, can potentially impact your insurance coverage. It’s crucial to inform your insurance provider about any changes to your vehicle’s specifications, as they may adjust your premiums or coverage based on the modifications.

Intended Use of the Tires
The legality of 37-inch tires can also depend on the intended use of the vehicle. For example, off-road vehicles or trucks used for recreational purposes might have more lenient regulations regarding tire size compared to street-legal vehicles.
Off-Road vs. On-Road Use
When using 37-inch tires for off-roading, it’s important to ensure they are suitable for the terrain and conditions you’ll be encountering. Consider factors like tire tread pattern, sidewall strength, and puncture resistance.
Key Considerations for Legality

- Federal Regulations: Be aware of NHTSA guidelines regarding vehicle safety and emissions.
- State and Local Laws: Research specific tire size regulations in your area.
- Vehicle Manufacturer Specifications: Adhere to the recommended tire sizes outlined in your owner’s manual.
- Insurance Implications: Inform your insurance provider about any tire modifications.
- Intended Use: Consider the intended use of the vehicle and ensure the tires are appropriate for the conditions.
Conclusion
