I've got a 2020 4Runner and replaced tires with Falken WildPeak A/T3W in stock size, though they're naturally slightly larger in diameter.

Looking at the owner's manual, it states "Install tire chains on the rear tires only. Do not install tire chains on the front tires."

Yesterday I did a bit of mountain road driving, had somewhat basic chains on my rear tires (want to get better ones!) but not having them on my front tires felt... not so great. I ended up sliding sideway on a hill, which I firmly believe wouldn't have happened with chains on the front.

Anyone running chains on the front? Any precautions or things to note? I imagine it has to do with clearance issues in the front, but shouldn't the 4runner wheel well have "plenty" of space, especially compared to the compact/luxury crossovers that have almost none?
