I wanted to reach out and give you an update on how the 37″ Sailun Terramax R/Ts performed: we just wrapped up running the Rubicon Trail (Most iconic trail in the US), and they exceeded every expectation.

Throughout the entire trail, they handled everything we threw at them—even when we got hit with rain and had to negotiate slick granite. We ran them down at 20 PSI carrying our nearly 10,000 lb rig, and they performed flawlessly. We experienced zero issues with tread chunking, traction loss, or sidewall flex and integrity. The grip on wet, off-camber rock sections was exceptional, and the sidewalls held up perfectly under the massive weight of the truck without a single scuff or pinch issue. We’ll be tagging Sailun across all of our social posts and upcoming video content from the trip so our audience can see how well they handled one of the toughest off-road trails in North America.

On top of that, our two Sailun videos that are already live on YouTube are performing exceptionally well across the board, especially ranking high in YouTube search and driving continuous engagement from viewers looking for real-world, heavy-duty tire reviews.
