IMO yes. It depends on where you live. Tire size you have etc...
I looked into replacement snow tires for my FX4. $875 installed for 20" tires. Then in the March or so, I'd have to have them swapped back over to the non snow tires.
Instead I purchased new 17" wheels, snow tires, sensors, mounted & balanced @ $1100 and do the swap myself. Keep in mind 17" tires are the most reasonably priced, and there's a wide variety of stuff out there.
