Glad the 4Runner will be wider (track). I know the hybrids (TRD Pro & Trail Hunter) come with 18"s on the Tacoma, but I'm skeptical this as anything to do with larger brakes (I could be wrong). The F150 Raptor comes standard with 35" tires and 17" wheels. Same for Broncos with Sasquatch 35s. My guess is that the choice for 18" wheels for the top end Tacoma is perceived customer preference.Sharing the F platform is definitely widening the Midsize vehicles, at least in terms of track width. You can pull up spec sheets for the '24 GX and LX- the dimensions are way closer than you'd think. Hopefully someone can get measurements soon to see if a "Tundra swap" is possible, just like the old "Titan swap" on the Frontier. While I don't think 35s will be a problem at all, so far all the Hybrid models come with at least 18" wheels. I'm pretty sure it's to accommodate the bigger brakes that go with the higher curb weight.
I definitely like the look of 17" wheels with 35" tires and prefer the taller side wall. Looks much more off-road oriented imo. Look at the new L.R. Defenders, they come with 19", 20" and 22" wheel options. That clearly shows Land Rover's de-emphasis on off-road prowess and focus on the wannabee mall crawling station wagon crowd.
EDIT: 2/9/24 12:31 - I just saw a video confirming that the wheels are 18" because of the large brakes
