    The TRD pro is lifted and I think it has larger tires. Does it have the same gear ratio as the other Tundra's? I recently lifted and increased the tire size, I want to regear. wondering if I can get gears from Toyota.

    I don't think the Pro has larger tires, and even if it does, they are not enough to warrant a re-gear. 35" tires are the beginning of re-gear territory from what I have read. The gearing is identical in all the current Tundras. You'll have to go after market to re-gear.

    I went to 35" tires and while noticeable, I dont think it justifies a re-gear.
    I just added 2.5" dual exhaust and can feel a definite improvement... so I think a couple more HP mods (headers) will help offset the larger tires.

    I think 37" tires would be a bit more of a struggle though... and would really benefit from more gear.

    TRD pro has the exact same drivetrain as every other tundra with a 5.7. Tires are no bigger. Toyota does not sell taller gear sets.

    yeah I'm regearing! I've got 34" tires. 35's are next. I've noticed a big difference. Speedo off by 2 MPH and a lot of gear hunting on hills and in stiff Gorge winds on the highway especially while towing my boat. I recently towed my boat 800 miles round trip and the transmission was constantly hunting on flat ground! Trans and engine just are working harder now and I'm thinking I'll benefit while slow off road trail riding too. Just wanted to know if Toyota offered a lower differential gear ratio.

    Is it ever not windy in the gorge?

    As others have stated, pro is all the same, just different suspension. Same tires too. If they are different it's a dealer add on.
