Gear to run

So I have a 2008 tacoma pre runner and I’m currently running 37s right now and need a gear reduction it’s a 4.0l v6 6-speed automatic 2wd and I was wondering what gear ratio I should run and I do plane on going with bigger tires in the future since I ordered a bigger lift.

 

Bigger than 37s?

Probably 5.29 I imagine

 

Ya that’s what I’m thinking bc I’m prob gonna be going to 40”s possibly 42”s In the future but I just want it to shift better and respond better so i plan on getting a bully dog tuner and a gear reduction.Which i was thinking 5.29 gears also just wanted to get opinions on it.
