If you’ve fitted larger tires to your Tundra, then you are likely experiencing a loss in performance, fuel economy, and more constant transmission gear “hunting” – This is because the larger tires reduce your engine’s RPMs below the optimal power band. These Tundra’s have a 6 speed Automatic Transmission with a very tall 6th gear. Any increase in tire size renders the 6th gear nearly useless as the RPM’s are greatly reduced. Re-gearing the differentials in your Tundra is the only way to get your vehicle back into its optimal operating RPM range, thus improving performance and reducing strain on your vehicle’s drivetrain. It’s a common misconception that gear changes are reserved only to hardcore off-roaders or trucks with huge tires. However, re-gearing is one of the single most beneficial modifications you can make to keep the performance, economy, and durability of your daily-driven 4×4. This is a mod for anyone with larger tires, increased weight, or for increased performance on stock vehicles for towing or increased acceleration.
