Key Features of 18 x 8.5 x 8 Tires
Tread Design
The tread design plays a significant role in the tire’s performance. Turf tires typically feature a smoother tread pattern for better grip on soft ground, while trailer tires have a more rugged pattern for increased traction on hard surfaces.
Ply Rating
The ply rating indicates the tire’s strength and load capacity. A higher ply rating means a tire can carry heavier loads, making it crucial for selecting the right tire based on your needs.
Load Capacity
Each tire has a maximum load capacity that should not be exceeded. This is critical for safety and performance, especially when transporting goods.
PSI Rating
The PSI (pounds per square inch) rating indicates the recommended inflation pressure for the tire. Proper inflation is essential for optimal performance and longevity.
