Ever wonder why semi-truck wheels have those “spiky” hubs—and why the same steel wheel shows up on the front, rear, and trailer? This episode breaks down the clever reversible wheel design that makes dual wheels possible (just by flipping the rim), why dual tires improve safety during blowouts, how weight limits protect roads, and the difference between stud-piloted vs hub-piloted mounting systems. You’ll walk away spotting the engineering genius hidden in plain sight on every highway.▶ Discover How to Pay Off 💵 Your Mortgage 🏠 in a Few Years 📅: https://www.udemy.com/course/payoff-y... 🎞️ 📖 INCREDIBLE BOOKS▶ How I Make A Six Figure Income On YouTube: https://geni.us/UZ2bnyd▶ How To Get Out Of Debt Fast: https://geni.us/HeWdQi1▶ Rethink Money: https://geni.us/YljOz9▶ Amazing Money Stories: https://geni.us/R7ef▶ Essential Disney Hacks: https://geni.us/cYZO3T0▶ 5 Strategies That Changed My Life: https://geni.us/dxPr▶ Insider Secrets for Transforming Travel: https://geni.us/QzzEgjo▶ Money Is Factscinating: https://geni.us/LckBTAXFOLLOW ON SOCIAL MEDIA:▶ Instagram:   / expedition.money  ▶ Facebook:   / expeditionmoney  ▶ LinkedIn:   / expeditionmoney
