Do I need to Re-Gear my 2023 Tacoma right away after installing 35's?

You'll need a viper cut (or something like it), at least, unless or until you do an offroad (high clearance) bumper.

Part of what you will have to do to get 35s to fit is push your tires forward in the wheel well (positive caster) so your tires don't rub the back of the wheel wells (cab mount chop or relocate will ALSO be needed, but you know that).

If you don't cut your bumper, or run an offroad bumper, the positive caster will make you rub the corner of your bumper.

 

I plan on getting it done within the next month or so. My friend has a 2019 SR5 4x4 Taco that's going to get the exact same set up as me, so we were planning on doing the same kit together on our trucks.

 

We'll let me know if you want me to do them.

It wouldn't be the first time I've lifted 2 trucks in a day. I'm pretty sure I can get some help. @essjay and @Blue Canary and some others and I have been talking about it's been a while since we've done a Mod Day.

I'll get back to you asap. the mod day is so freakin sick!!

 

It's interesting you say that. I only ever called Deaver twice - once to order some leaf packs, and a second time to ask for different u bolts since they sent the standard squared type and I asked for the rounded type for a flip kit. Both times I got someone on the phone and had great service. It was 3 years ago but that was my experience.

 

You'll be alright just get an OTT tune and no PC

 

FWIW I've run 35 x 12.5s with no regear for 50k miles, no functional problems yet other than its really slow, I got an OVtune and that helped a ton, but finally getting the 5.29's done and very much looking forward to it.
