How to choose wheel chocks

To choose the right wheel chocks, you must consider the vehicle's tire size, weight (GVW), and the surface conditions where the vehicle will be parked. For optimal safety, a chock's height should be approximately 1/4 the height of the tire, and its weight rating must exceed the vehicle's loaded weight. You'll also need to select a material (like rubber or urethane) and design (like a wedge or pyramid) appropriate for the terrain and any specific environmental factors, such as ice or chemicals. 
1. Tire Size:
Height: Choose a chock that is about one-quarter the height of your vehicle's tires to ensure a secure fit. 
Width: The chock should also be wider than the tire for maximum effectiveness. 
2. Vehicle Weight:
Capacity: Check the chock's weight rating to ensure it's suitable for your vehicle's Gross Vehicle Weight (GVW). 
Heavy Duty: Heavier vehicles, industrial equipment, and large trailers require heavy-duty chocks to prevent failure. 
3. Surface Conditions:
Grip: For wet, muddy, or icy surfaces, use chocks with cleats or a rubberized bottom to provide better traction and prevent sliding. 
Steep Grades: Vehicles parked on a steep grade will require heavier-duty chocks. 
Multiple Chocks: Depending on the surface, you may need to use multiple chocks to secure the vehicle safely. 
4. Material and Type:
Rubber: A common and durable material, offering excellent grip for general use. 
Urethane: A lightweight, durable alternative to rubber, often used in harsh chemical environments. 
Aluminum/Steel: Best for heavy-duty applications and high gross vehicle weights. 
Double-Sided vs. Wedge: Double-sided chocks are versatile, while wedge-style chocks can cradle the tire more effectively. 
5. Check for Damage: 
Inspection: Always inspect your wheel chocks for damage before each use. Do not use damaged chocks, and replace them to maintain safety.
