Choosing the Right Tire Type
I learned that there are different types of trailer tires, including bias-ply and radial tires. Bias-ply tires are generally more affordable and work well for lighter loads. However, I found that radial tires offered better durability, improved traction, and heat resistance. Given my usage patterns, I opted for radial tires to ensure a smoother ride and longer lifespan.

While I wanted to stay within my budget, I also understood that opting for the cheapest option might not be the best long-term investment. I looked for a balance between cost and quality, ensuring I was getting good value for my money.
Reading Reviews and Recommendations
Before making my final choice, I spent time reading reviews and recommendations from other trailer owners. Their experiences provided valuable insights into the performance and longevity of various tire brands. This research helped me feel more confident about the quality and reliability of the tires I was considering.
