35’s look normal on these I feel like, and 37’s look great. Especially because every other factory truck comes with 35’s or 37’s these days

Thanks for posting! Your "full fat 35's" thread was very helpful when I got my first set of 35's.
I just switched out my 1" BL for a 1.5", so hopefully things will be a little easier for me. Loving my 35's, but still scraping belly through the rocks nearly every outing, so 37's seem like the next logical step. I actually feel like 4.88 on 35's is a little too much gear, so 37's might bring shift points back to their happy place.

Okay, write-up in the above posts done!
Right? So far I'm pretty happy with them but yes, snow and ice is one area the X-ATs will be a compromise on. Part of the tire calculous is that since I'm keeping a 35" spare, I wanted to run a more robust R/T tire for the 3-ply construction. Pleasantly surprised how comfortable and quiet these tires are given how much more aggressive the lugs seem.
Right? Friends factory specials come riding on 35s and 37s stock, but Toyota is still too conservative. At least we know the 200-series has enough beef and structure to run 37s in the Baja 1000.
Nice. Looking forward to your build!

Second long weekend trip out. 37s deliver and totally worth the upgrade. Impressions are substantial improvements in overall clearance and angles. Rocks look and feel smaller.
Did some business in the dunes and sand. Floatation is awesome. Where I would bog down previously on super steep dunes, this tire set maintains floatation longer and can surprising to put power down where I thought would be impossible. Love it.

Getting to the details. As winter is coming, wanted to make sure I had mudflaps so salt, sand, and road grime doesn't get sprayed down the chassis. I got stock mudflaps to work with 35s. Homebrew for 37s with generic flaps cut to fit.

Those actually look pretty good. Nice work!

Looks so damn good! Man I wish I could get away from these tundra arms and use smaller mudflaps like yours!
I need to do this.
TeCKis300 - we need pics in normal and then lo/hi mode for AHC with the 37's.
My Harrop just arrived so I'm lining up the install for Jan. Will be planning wheels/tires next. MY 1.5 BL from NST already arrived so I'm debating between 35's or 37's. I was originally planning 35's for daily and then swapping but when you get to my age these days, that sounds like too much effort if 37's is just about right anyway. Can you send us some hi/lo/normal shots to go with these amazing glam shots?

Just for you.
I have my 35s in the garage and I thought I would similarly do some swapping. Now that I've had some months of commuting, 3x major offroad trips, along with a 1300 miles road-trip on this setup, any thought of swapping is out the door. The 200-series, or specifically the LX, is fantastic on 37s. I attribute much of the daily livability to AHC and it greatly eases the day to day ergonomics of such a large tire. AHC also handles the wheel/tire package weight well, and drives butter smooth on the highway.
Sometimes I do park with it in AHC high and it can be like falling out of the truck with as tall as it is. AHC L makes car camping great as it brings it down to a level where the tailgate and RTT are usable. I can sneak into 7' parking garages.
There is more weight transfer with the taller overall height, but the roll control of the system is especially appreciated and it can still be fun on secondary mountain roads. Most of the roll is in the tires/sidewall so I find I like more tire pressure than required. RCTIP puts it at 35 PSI yet I prefer 45 PSI, and the ride on long road trips is still excellent (at least with the Yoko X-AT I run).
With your 1.5 BL, just jump into 37s!

Adding a few things.
I revised an earlier post in this thread about the front sway bar. So far so good with clearancing a section of the bar about 1/2" in, and rewelding reinforcements. Gives me back all the turning clearance I need. Especially in AHC high or when the tire is drooped, with more down-angle on the LCA that pulls the tires closer in towards the frame. It still rubs a tad on more extreme turns, but not enough to be of concern now.

Clearancing Sway Bar for Large Tires
Looking to get this discussion going as to strategies to fit larger and full fat meats. I recently modded the LX570 sway bar to allow full steering lock on 37x12.5s. For context, I'm running +28 offset and on AHC high (about 4" total lift creating down-angle on the LCAs which pulls the tire...

Approach, Breakover, and Departure angles on 37s is approximately 42°, 39°, and 39° respectively.
Here's measuring approach, breakover, and departure angles. Not completely scientific, but this method should provide angles within a few degrees of real measurements.

A solid profile shot taken from further back (maybe using a 2x zoom) will provide a better perspective for measuring. On Android, I'm using Angle Meter 360 to get angle overlays. Looks like the app is available on iPhones too.
I'm pulling angles across both tires so I have a better horizon reference in case there is any tilt in the picture. Using basic geometry to arrive at angles. For example, this would be 180° - 138° = ~42° approach.

Breakover would be 180° - 141° = ~39°

Departure is 180° - 141° = ~39°

This is an '09 LX570 on a 1.5" sensor lift, AHC high 3" suspension lift, .75" body lift (that lifts bumpers), and 37x12.5R18 tires to get approach, breakover, and departure angles of approximately 42°, 39°, and 39°.
As a reference, here's stock angles discussed in this other thread. I've seen it suggested that a good off-roader will have angles in the 30 range. A strong off-roader should be in the mid-high 30s. For reference, a Bronco Raptor has angles of 47.2°, 30.8°, and 40.5° respectively.

Definitive LC and LX Approach, Breakover, and More Angles
Definitive guide to LC and LX approach, breakover, and other angles. There's some variation between model years. Here's my attempt to document these details as a reference. Please correct me if you find a source that helps clarifies any of these numbers.
These are big numbers. Wow. I don’t remember the OEM ones but even with the AHC it was never great in the 200’s. But what you’re getting now is awesome.
And these pics and write up are next level. Keep pushing the envelope pls. And thanks for throwing this together.
How are you liking the Yoko’s? I was considering the Toyo’s and the Falkens for my use case, which is a lot of on road mileage per year currently 20-30k / yr and then snow / skiing trips.

Sorry missed this. Yes, the numbers have gone way up and the obstacles it will now tackle and clear does support it. The numbers are all the links above but stock for the '09 LX in high was 31°, 23°, 27° versus 42°, 39°, and 39°. I'd say a big part of the improvement is due to the faces of the tires being closer to the bumpers horizontally, than just that gained from lift.
I like the Yoko AT-Xs more than I thought. Got them for a deal I couldn't pass up. It's an aggressive tire that feels well balanced with good NVH. I would get them again based on how I'm using them. That said, it does still give up some NVH over a good A/T tire like Toyo or Falken. I've yet to run them in really cold weather/snow, and I might be more cautious there based on my research. They are less tailored for that use with less sipes and biting edges. They could still be good in some types of snow with more voids to pack in snow for better snow on snow grip.
I had 37x12.5” Yoko G003’s on my 4Runner and thought they were pretty great for how aggressive they were. I didn’t think they were much louder than the 2 sets of KO2’s I was running at the time on my GX and F150.

Have you used the Yoko AT-Xs in the rain yet? I know its been pretty dry this season in SoCal. That's my main thought of sticking with a more traditional AT vs more aggressive like the Yoko AT-X or Toyo RT Trail. Where did you get a good deal on them?
Well now I’m leaning 200 Series instead of 100 lol. That 570 build is beautiful man, I mean goodness. That’s the best one I’ve seen so far on the forum for sure.
I’m coming from a fairly modded Jeep Gladiator on 37s so a completely different animal. I was primarily looking at 100 Series but now idk. I’ve got much more research to do, that’s for sure ha.

Thanks for the kind words.
Having come from the 100-series, I love that model too and it has many merits. I think the major differentiator is how much payload and towing capacity you might need, or if you're a power junkie. Towing a large travel trailer is what drove me to the 200-series.
