Tire (and a few wheel) options spreadsheet

The pic below shows calculations to determine how the offset and rim width change the overall position of the wheel relative to the suspension (for a 285/70R17 +35 on 8.5" width rim). The additional poke is 37.7 mm (or 1.48") when compared to the stock 20" wheel. So, the new tire will still be under the fender. The only thing that changes if I go to the 285/75R17 is the overall diameter of the wheel.
If I would've chosen the Method 708 (+40 offset, 9" wide rim), the actual poke would be 39.1 mm which is more than I'd see with the +35 offset/8.5" rim on the 703s. The calculated values are shown in the second picture.
Here is a link to the offset calculator and wheel comparison: Alloy Wheel & Tyre Fitment Calculator. Offset, Tyre Stretch and Speedo Error | Will They Fit
Here is the formula to calculate the difference in Poke (width of wheel in inches, offset in mm):
(width of new wheel - width of old wheel)/2*25.4 + (offset of old wheel - offset of new wheel)=change in poke
For the 703:
(8.5-7.5)/2*25.4 + (60-35) = +37.7 mm (1.48") additional poke
For the 708:
(9.0-7.5)/2*25.4 + (60-40) = +39.05 mm (1.54") additional poke
I think the 285/75R17 will fit under static loads, but may deform enough during dynamic loading to rub a little bit. So, if I go with the larger diameter, I'll be looking at doing a proper suspension upgrade with just enough lift to give me a comfortable clearance. Radflo already has something out, but I'm wondering if Bilstein will also come out with an LC tuned suspension package. I'm just not sure the juice is worth the squeeze to get an extra 0.5" to 1.5" clearance for the type of off-roading I'm going to do in the LC. I may wait and see how the LC performs with the new boots and stock suspension on the trails before trying something new. Plus, with more time, we'll probably have more options and I'll be able to find the right suspension for my off-roading.
I was looking the 708 HD as well. I wanted to get the Bead Grip (I don't think they offer any bead lock to fit). Sorry, but I don't know what vehicle you are using as a baseline for poke - I'm guessing you have a Premium, since you use 20". I don't have a 1958, so I think we have same poke. I'm also looking at rub at full turn when flexed. I'm looking at Dobinson's IMS kit. Too bad the wheel well isn't in their calculator!!
Thank-you for sharing your insight. I'm still thinking to get 18s though (708) and I will get a ~2" lift in the spring.
The wheel on the 1958 is a 7" width and +50 offset on an 18" rim. The 708 HD is a good look and will look really nice on the LC. The calculation for the comparison of the 1958 wheel to the 708 is...
(9"-7")/2 *25.4 + (50-40) = 35.4 mm extra poke
That's actually a little bit less than the poke I'd see when comparing the 703 to the standard wheel on the LC 20" wheel.
One more thing to think about...the weight of the 708 HD is 36.43 lbs (18") and the weight of the 703 is just 27.84 lbs (17"). So, not only does the 708 HD weigh substantially more (31% more), the amount of rotational inertia it has will also be magnified because it is a larger diameter (rough estimate would be that the heavier wheel will have more than 45% rotational inertia than the lighter and smaller 17" wheel). Rotational inertia is only important when you are speeding up or slowing down.
Head's up Yokohama Geolandar A/T4 G018 is replacing the G015. Its initially LT/E range only, but the 265/70-18 is 51#.
The Bridgestone Dueler Ascent is replacing the Revo 3 and it is also a lightweight at 39# for SL and 48# for the LT in the 265/70-18 size.

I just ordered the A/T4. Should get them next week. Staying with 265/70r18
I recently bought a 2025 LC (LC trim) and I'm trying to determine if there is a tire + new wheel combo (both) that can get me in a 34-35” AT tire with no lift or trimming. I am ok removing the mud flaps, but would like to keep the suspension stock for now.
Uraniumrich - have you completed your upgrade? Did you go with the 285/75R17 or the 285/70R17. The method 703 with 35 offset look great online and seem like a great combo. Do you have pictures?
Anyway, this conversation has been very helpful. Would enjoy hearing from anyone that has been successful upgrading to a +34” with no lift or trimming. Thank you!
ICON has a pretty good YouTube video going through different tire sizes and offsets for the LC250 btw.
I ended up going with Falken WildPeak AT4W LT255/80R17 on Method 703s. Click the link for a really detailed post and pics. The tires are a true 33", but actually lifted me up more than expected. I'm guessing that the stiffer sidewall and higher pressure (39 psi) I'm running on the AT4W are the reasons for the additional clearance (I got about 3/4" instead of the expected 1/4"). The spare fits nicely underneath, with plenty of extra room. I'd bet that a 34" will just barely squeeze into the space. I'm very pleased with the new wheel/tire combo on my LC.
This is awesome, thanks for sharing!

The wheels tab isn’t nearly as complete as the AT tire list. I add new 18” wheels if I hear about them.
Did you ever find this? I really like the Fuel Rebel Dark bronze rims, but they only come in a +20 offset. I want to put on 285/70/18, otherwise Ill have to lift it and just do 285/75/18
Yes- thank you for your spreadsheets (and the forum as a whole). It made narrowing down all of the wheel and tire choices and variables much less painful.

They don't have a black rim, but Method has some bronze options now.
If I was buying new wheels today I'd get these bead grip wheels (helpful if you need to air down):

Better add these bad boys to the spreadsheet!
I have a 285/75r17 on 17x8.5 +25 offset. So far only rub is on reverse but i took mudflaps and cannards off. To me it is too close for offroad so moving to 18x9 +40 offset and similar tire size.
