How Big Of Tires Can You Put On A Stock Toyota Tundra

How Big Of Tires Can You Put On A Stock Toyota Tundra? For Toyota Tundra owners seeking to elevate their truck’s performance or appearance, upgrading the tires is a popular option. However, determining the maximum tire size for a stock Toyota Tundra involves various considerations. In this comprehensive guide, we’ll delve into the factors influencing tire size compatibility, explore potential upgrades, and provide practical advice to help you make an informed decision.

The maximum tire size that will fit on a stock Toyota Tundra without any modifications typically ranges from around 33 inches to 35 inches in diameter.

Considerations Beyond Size

When choosing larger tires, there are several additional factors to consider.


The weight of larger tires is generally higher compared to smaller ones, which can have multifaceted implications on various aspects of vehicle performance. Specifically, this increased weight can influence factors such as fuel efficiency, acceleration, and braking effectiveness. Understanding these effects is crucial for making informed decisions when selecting tires, as they can significantly impact both the driving experience and long-term maintenance costs of a vehicle.

Gear Ratio

When considering larger tires for a vehicle, it’s crucial to take into account their impact on the Gear Ratio. The stock gearing, optimized for standard tire sizes, may not be well-suited for significantly larger tires. This mismatch can have notable consequences, such as compromised acceleration and engine performance. Essentially, the larger diameter of the tires alters the effective gear ratio, leading to a reduction in torque at the wheels. Consequently, the vehicle may struggle to accelerate as efficiently, and the engine might experience increased strain due to the altered mechanical advantage. Therefore, it’s advisable to recalibrate or even upgrade the gearing system to ensure optimal performance when switching to larger tires.

Speedometer Calibration

When you opt for larger tires on your vehicle, it introduces the possibility of interfering with the readings displayed on both your speedometer and odometer. This alteration can result in discrepancies within your driving data, potentially impacting the accuracy of your speed and distance measurements. In instances where such discrepancies occur, recalibration becomes imperative. By recalibrating your vehicle’s systems, you can effectively preserve precision, guaranteeing that your speed and distance calculations maintain their reliability and accuracy over time.

Suspension and Handling

Choosing larger tires for your vehicle can significantly influence its handling characteristics and overall performance. While larger tires often provide enhanced traction and off-road capability, they can also introduce several considerations that affect driving dynamics. These include improvements in grip and stability, particularly in challenging terrain, yet they may also lead to changes in steering response, potentially affecting the vehicle’s agility and maneuverability.

Moreover, larger tires can alter braking distances, as the increased rotational mass may require adjustments in braking techniques to maintain stopping efficiency. Additionally, the choice of larger tires can impact ride comfort, with potential trade-offs between a smoother ride and increased road feedback or noise. Thus, when selecting tire sizes, it’s essential to consider not only the desired performance benefits but also the potential implications on handling, braking, and comfort.

Warranty and Liability

Modifying your vehicle beyond manufacturer specifications may void certain warranties and could potentially impact insurance coverage in the event of an accident. Always check with your insurance provider and read the warranty terms carefully before making modifications.

if you modify your Tundra, particularly in ways that could affect other components, there’s a risk that the warranty on those components could be voided. For instance, if larger tires lead to premature wear on the suspension or brakes, Toyota might argue that the modifications caused the issue and thus may not cover the repairs under warranty. It’s always a good idea to consult with professionals before making significant changes like upsizing tires.  When upgrading your tires, it’s important to consider all of the factors involved. Especially your Toyota factory warranty or your Toyota Factory Extended Warranty, you wouldn’t want to make any decisions that could potentially void your warranty.
