I have 285/70/R18 +18 offset. I just added mine a few days ago. No issues.

Slightly slower acceleration after upgrading my tires (275/70/17), but not too noticeable overall. My speedometer is off by about ~2mph when on the freeway

I have a non-hybrid ORP with the same 8-speed auto as your SR5. I'm running 285/75R17 tires and I have not noticed any shifting issues. I also have not felt noticeable changes in acceleration, although I realize there is probably a marginal performance decrease due to the larger tire diameter.

How often are you seeing this behavior? Does it happen consistently, or only once in a while? Do you usually keep it in Normal drive mode, or do you use Eco or Sport?

Personally, if I were seeing the issue consistently, I would be concerned enough to have a Toyota dealership look at it, and I would also try the other drive modes to see whether the different shift point tuning changes how the transmission behaves.

thanks for providing your information on your 285's..i was afraid to put those on my 6th gen 2025 4Runner SR 5 parttime 4wd..i thought they would rub..did you have to do any cutting or mods? thanks in advance..

I have a ReadyLIFT 2.5” SST Lift Kit and Method 703 17X8.5 6X5.5 +35 wheels. These were installed by a shop, but AFAIK they didn't cut anything. I haven't noticed any rubbing so far.
