I wouldn’t say smoother than stock but stock tires are also highway tires but they’re still very smooth and not a big difference you can just tell you have bigger tires if that makes sense. You do get a little bit more tire noise but not bad. Sacrifices you have to make to have the 4Runner look...
There Falken Wildpeak 285/70/17 load Range E. Got them slightly used on Facebook. Haven’t noticed much in mpg but I also went into it knowing I’m not gonna get great gas mileage so I try not to pay attention to it lol. More about the smiles per gallon for me. I took the air dam off right away...
