We definitely recommend a wet-saw. You need not buy a commercial wet saw - even a basic wet-saw will do the trick. The key attribute will be a quality blade.
Technically, you can use a score/snap cutter to snap the tile, but it will NOT cut the polymer substrate. It is a tough material to cut. The best and recommended solution is a wet-saw.
Another alternative is taking the tiles to your local home center - in many cases they will cut your tiles for a reasonable fee (call ahead to make sure they offer the service). If you choose this method, remember the old adage: "measure twice and cut once" - it be frustrating to make multiple trips to the hardware store.
Regardless of which method you choose, please use appropriate safety precautions, especially safety glasses.
Enjoy your new Avaire floor!
