37s on new Tundra

So like the title says, I’m considering 37” tires for my Limited Off-Road. Would be on either 17” or 18” wheel depending on what I can find for fitment. Partially for more clearance off road and partially because I think they look sick. My concerns are fitment especially with articulation off-road and issues with increased weight of tires/wheels.

Fitment: Anyone have any leads on what might need to get cut or how they can fit? I’ve seen several people on Facebook and instagram who have done it. Also, anyone here with 37s that off roads with them, do they rub and if not how did you get them to fit.

Weight: anyone here know how to tell if my brakes will be overwhelmed by the extra weight? I know speedometer will need an adjustment for the larger tires.

Any other considerations I should be thinking of? If it’s really problematic I could go with 35s instead which I know are a lot easier to make work. This is my first truck, I’m pretty new to all this and I appreciate any help that could be offered.

This is a good start, plenty of YouTube videos of people running 37’s and same with instagram. Scroll through the comments and some say what they had to cut and mess with to get a good fit.

Weight will be heavier definitely compared to a 35 but kinda all depends on what rim you are running and all tires don’t weigh the same so see what they say before purchase, brakes should be just fine, personally haven’t had any issues from going up in tire size.

Some random thoughts, 37’s are pricy so if money or a budget is a factor try to wait for discounts or sales on that specific tire you’re looking for.

 

Youre gonna need at least a spacer lift or collar lift (Westcott Designs) to clear efficiently and not bottom out, and to avoid cutting anything. Even then, depending on your wheel offset, youre probably going to have to remove or cut the end off of the wheel safety stops in the wheel wells to clear.
Personally I wouldn’t want to go cutting. 35’s are probably a better option, but thats just me. Even then, I’m putting a collar lift on tomorrow (had to wait for bigger spring clamps). With 35s I am only off a few mph (2-3) depending on speed, based on GPS readout. 37s are gonna put you at 5mph faster at least.
I don’t know of a way yet to correct for size difference but JB4 may have this option or it may be something they add.

Start with this thread:

When I do eventually upgrade my wheels/tires I will already have a coilover/shock/UCA upgrade. I’m not afraid of a little cutting, more concerned about having rubbing off road even after cutting.

 

All the more reason to stick with 35’s if you plan on flexing anything or going hard. Id rather have the extra clearance with 35s personally. If you’re just going to be on road and like the 37 look, you’ll otherwise be fine though.

 

Yeah he’s got a good point with 35’s you’ll likely have more articulation before rubbing than 37’s although I must say 37’s look killer on the new tundras. Looks like they belong there.

 

I know 35s will be easier, that’s my backup plan. That being said, I have seen several rigs set up for off-roading with 37s on instagram, some “influencers”. Maybe I should take that with a grain of salt and maybe they aren’t actually off-roading but it seems like they are. Just hoping someone who has actually done it can chime in here because, like you said, 37s look like they belong on this truck!

 

This guy took his tundra on 37's for a bit of offroading, and it didn't go so well. Not saying he has the best offroading setup by any means, but I think he has a 3/1 lift and 37s, and he was rubbing like mad on the back wheels with pretty minimal articulation. 37s look awesome, but functionally may be an issue. The front rubbing could be fixed easily enough by chopping those cab mounts and pinning up the liner, but idk what you do about the back besides lift it higher.

That was painful to watch. You can drive everywhere at Pismo in 2WD if you AIR DOWN your damn tires.

 

Yeah it's bad lol, but does highlight the potential tuck issues with 37s in the rear. Though some would depend on your wheel offset. There is really no right answer. Just go with what you feel.

 

What I feel is not buying two sets of tires because the first ended up rubbing too much. Sounds like maybe I should go with 35s and by the time those are worn out I will have gathered more info on if 37s can even work.
That being said I’m several months out from my suspension upgrade anyway. Lol

thanks for the help folks

 

didn’t watch it but 1) offset of wheels and 2) not enough rear lift/ trimming for 37’s, guy is probably running a spacer lift and called it a day

 

I will be putting 37s on my '22 Tundra in the next couple of months or so. Stock suspension because the suspension setup I want won't be released until next year. I will be clearing them properly all the way through the travel (coils removed, and suspension/steering cycled) and shooting a YouTube video about the process. If you want to subscribe to my YouTube channel (<-link) you won't miss it. I use my trucks pretty hard and they get abused.

Lift height doesn't matter if you offroad as the wheel will bottom out in the same spot no matter the ride height. If you just want them to clear around town, a lift will help.

For reference, I have 37's on my 2006 Tacoma with long travel, and tubbed the wheel well and fire wall back around 4+". I own an offroad shop, and all we work on is Toyota's, though this is my first Tundra. My other vehicle is an '88 4Runner.

Here's a link to my Tacoma build thread when I started the 37 tubbing if you are interested.

 

Yeah man, I’ll definitely subscribe! I would like to eventually get 37s on for looks as well as having more rubber on the trail. I may let dudes like you pave the way while I wear out my first offroad tires (in 35”) and then follow in your footsteps. Thanks!

 

100% correct. But as I said, not the best example of how to fit 37s. It does highlight that it requires more than a cheap lift to make it functional.

 

Guy actually has a 3.5" Rough County lift, but even with that much of a lift and 37"s he was rubbing like mad during his "off road" adventure.

Enjoy The Ride on Youtube has the same RC 3.5" lift with 37s, but his truck was cut and modified by Southern Style Offroad. That set up is actually pretty clean. No comment on the skill of the driver lol

I'd actually say that able to fit bigger tires has nothing to do with amount of lift the truck has if people actually offroad. For me, the tire has to not rub under full suspension articulation, at the full up travel/tuck, the amount of lift would not matter.

 

There's someone already running 38's 38x13.50R17.

I'm sure a lot of cutting had to be done, and still rubs when offroading. I believe he running the Fox coilover like Adventure motors, but he did it himself using Fox from F150.

Quoting this so it's said again because 90% of the replies in this thread are misinformation and of no help.

OP said he wants to articulate and off-road, the ONLY thing that will stop rub is cutting or extending bump stops. "Lift" has NOTHING to do with where your suspension bottoms out.

 

Strange question for you- i stripped out a front sway bar bolt installing my front bumper, whats the best way to fix it?

 

Remove it.

 

Talked with the adventure motors crew and they tried no front sway on the 22 and it was a nightmare, wayy too much over steer. The 22 is a different animal vs the prior gens

 

Same. Looking to add 37's to 2023 Tundra Limited. Have a 4" lift currently.

 

37" tires will complete the very nice look and stance on your Tundra with a 4" lift.

 

Had to remove all mudflaps, do a horn chop, and trim wheel liners both front and rear to make it all fit without rubbing. Taking it off-road next week, that’ll be the true test as far as rubbing.

3 inch lift in the front and 2 inches in the rear

 

Beautiful rig!!! I love how it looks! I have a 4" lift on mine, run 37X12.50 tires, and I've done the same chopping and trimming you did, but was I still rubbing when I took mine off-roading. The cause was the zero (0) offset wheel I previously had on the truck. This gave me a more positive scrub radius and with the wider tires made rubbing and scrapping more prevalent when off-roading or even when turning while under heavy braking driving in city streets. I'm now running a +25 offset wheel and no more rubbing regardless of where I am and how I'm driving.

 

Very happy to hear you don’t have rubbing anymore since I’m also running +25 offset on my wheels. Went with KO2s cause they run a little smaller and I figured that would help

 

I think the sweet spot for these trucks are wheels with +20 to +30 offsets if you don't want any rubbing problems. Sure, 0 offset and negative offsets look so much better, but then we give our rigs more limitations when driving on the trails.

 

I've gone to several Upfitters shops and they all say the wheels will rub. Any suggestions?
Thanks for the reply btw
