Properly position your tree
Aerodynamics play a big part in keeping your tree in prime condition when travelling at speeds that quite frankly are not intended for a tree. You’ll want to position your tree on the roof of your car so that the wind travels through the tree in the direction of its branches — in other words, you’ll want the trunks to be opposite each other. By this we mean put the trunk of the tree nearest to your windshield, and the top of the tree nearest the trunk of your car. Makes sense, right?
Know your ropes and straps
Ropes, straps, buckles, knots — everyone has a personal preference. It's recommended to avoiding bungee ropes or anything with too much elasticity or give — as these can overly flex in the wind at driving speeds causing items to move in place. A thick rope or twine will do, and if this is your preference it's recommended to select a non-slip option (avoid nylon or anything with a sleek finish). You’ll want to freshen up your knowledge of a good overhand loop knot or slip knot in order to properly secure the tree to your car.
If you’re going for the absolute safest route (always our recommendation), best practice is to use ratchet straps with a buckle — precisely three — one for the trunk, one for the middle of the tree, and one for the top.
