What size tires can I put on my truck without a leveling kit?

When it comes to customizing your truck, one of the most popular modifications is upgrading the tires. However, if you don't have a leveling kit installed, you need to be mindful of the tire size you choose to ensure a proper fit and avoid any potential issues. This article will guide you through the process of selecting the right tire size for your truck without a leveling kit.


Understanding Tire Sizes


Tire sizes are typically expressed in a format like "LT265/70R17," where "LT" stands for "Light Truck," "265" is the tire width in millimeters, "70" is the aspect ratio, "R" indicates a radial tire, and "17" is the wheel diameter in inches. The key factors to consider when choosing a tire size without a leveling kit are the tire width and diameter.


Factors to Consider


When selecting a tire size for your truck without a leveling kit, you need to take into account the following factors:



  • Clearance: Ensure that the new tires will have enough clearance between the tire and the fender, suspension, and other components of your truck. Measure the available space and compare it to the tire size you're considering.

  • Speedometer Accuracy: Larger tires can affect your speedometer's accuracy, as they will make your truck appear to be traveling at a slower speed than it actually is. You may need to recalibrate your speedometer to compensate for the larger tires.

  • Ride Quality: Larger tires can also affect the ride quality of your truck, potentially making the ride rougher or less comfortable. Consider how the larger tires will impact the overall driving experience.

  • Fuel Efficiency: Larger tires can also affect your truck's fuel efficiency, as they require more power to accelerate and maintain speed. This may result in decreased fuel economy.


It's important to carefully consider these factors and consult with a professional if you're unsure about the appropriate tire size for your truck without a leveling kit.


Recommended Tire Sizes


As a general guideline, you can typically increase the tire size by one or two sizes without a leveling kit, as long as the new tires fit within the available clearance and don't significantly impact the other factors mentioned above. For example, if your truck came with 265/70R17 tires, you could potentially upgrade to 285/70R17 or 305/70R17 tires without a leveling kit, as long as they fit properly.


It's always best to consult your truck's manufacturer recommendations or speak with a professional tire and suspension specialist to ensure you choose the right tire size for your specific vehicle and driving needs.
