265/70/R16 on 2016 Tacoma Ltd?

I'm considering purchasing a 2016 Tacoma Ltd that comes with 265/60/R18 tires. I have some newish 265/70/R16 snow tires from my old SUV vehicle. I'll need snow tires here in winter. Any thoughts on tires/wheelsize etc?
Also, any tips on better snow traction in a Tacoma beyond throwing some sandbags in the bed?

 

I'm in AL so can't really help with the snow tire advice but I will say ride quality suffers with 18" wheels on these trucks, in my opinion. My buddy has an XSP model Tacoma with 18's and he can confirm it rides worse than my truck with 16's. It rode so poorly when he had KO2's he almost got rid of the truck.
