There are a ton of examples on this site where folks have put 285/70R18s on TRD PRO and Trailhunter, but fewer clear examples for the same tire on TRD Off-road (Premium or not).
The stock tires for these 4 trims are different brands but same size: 265/70R18. The stock wheels have different offsets: (ref: factory-wheels-tires-oem-offsets-bore-sizes-widths-brands-2025-4runner-6th-gen.)
TRD Off-road: +55
TRD off-road flat black (option): +45
TRD PRO (Black): +20
Trailhunter: +20
I'm contemplating putting 285s on my TRD ORP, using the +45 offset wheels (since I'd like to avoid changes from stock (except tire size)). And I'm trying to figure out whether all those references to putting 285s on TRD PRO without lift or rubbing will be true for the TRD Off-road trims.
Some pertinent facts (available from Toyota and here: 2025 4Runner Specs Product Info )
Overall height (does not include roof rails or roof rack) :
ORP*: 73.6" (*spec sheet says ORP on p. 3. I believe this is same for OFR non premium)
PRO/TH: 74" "
Ground Clearance:
OFR:: 9.1"
PRO/TH:: 10.1 "
I'm looking to better understand exactly how the PRO and TH get that extra .4" of overall height and 1" of ground clearance vs. the OFR trims AND how to reconcile those two differences. (I.e., I'd like to understand how both measurements can be true?)
I know the PRO has FOX QS3 shocks and the TH has Old Man Emos.
What is the "low point" where clearance is measured? Assumedly the suspended height is .4" higher from effectively longer springs/shocks but not sure if the clearance is to a frame location (or differential?) and where does that extra .6" come from?
I know there are a lot of experts here and I guess I could use a tutorial, and really would like that to come with facts based on the actual design of the different 4Runner trims.
I am looking to make a decision about tire size, but at this point I just want to understand the differences. And the AI answers that I have found seem wrong - arguing that tire size is the source of the difference in clearance when I am fairly certain the tire sizes are the same. (The Toyo Open Country A/T III All-Terrain tires (265/70R18) on the PRO/TH are the same diameter (32.6") as my Michelin LTX Trails. ref: Toyo A/T III specs)
Some other 4Runner6G.com links that don't quite answer my question but are valuable references:

Thanks in advance for any insight.
