### ⭐⭐⭐⭐⭐ Review
*by S***L on 24 August 2025*

I originally bought these just to install my spare tire on the boat trailer, but once I saw the quality and finish, I decided to replace all the lugs on the trailer wheels too. They fit perfectly on the 1/2-20 studs, tightened down securely, and I really like the conical seat design. I have confidence that the wheels are staying in place. The black finish looks sharp and gives the trailer a clean, upgraded look. They feel very solid and durable, and the corrosion-resistant coating is a big plus for a trailer that’s often around water. It’s also nice that they come in premium packaging, making them easy to store and keep organized. Overall, these exceeded my expectations. They are strong, stylish, and reliable. Definitely recommend for anyone needing replacements or just wanting to upgrade the look of their wheels!
