What kind of rope should I use for a tire swing?
Polyester rope: Braided polyester rope (available at The Home Depot) is the best rope choice for a tree swing. It holds up well, provides maximum strength and has little stretch. Nylon rope: Nylon is the strongest rope, however it can be slippery for hands to grasp when needed. A good swing branch should: Be at least 8 inches in diameter (strong enough for years of use) Be a mature tree—older, well-established trees are usually more wind-resistant and hardy, making them safer long-term than young or recently planted trees.
