When you’re logging thousands of miles in a fifth-wheel toy hauler, unexpected bumps in the road—literal and figurative—are bound to happen. Over the last year and a half, we’ve traveled more than 18,000 miles with our 2024 Forest River 373BS13 Toy Hauler in tow. It’s been an unforgettable ride hauling our Harley Tri Glide—and sometimes our Road King—as we chase sunsets and scenic routes across this incredible country.
But sometimes, RV life throws you a curveball… or three. In our case, it’s been cracked aluminum wheels. We’re sharing our experience not as a complaint, but as a heads-up for fellow RV travelers who may be facing—or hoping to avoid—the same issue. If you’ve ever wondered about the difference between aluminum and steel wheels for RVs, or if you’re just here to learn from someone else’s journey, buckle up. This post is for you.
The Road We’ve Traveled—Literally and Figuratively
Let’s set the stage. We’ve got a solid setup with our 2024 Forest River 373BS13 Fifth Wheel Toy Hauler. It’s a rig we love and have confidently taken on long hauls. But about a year ago, while staying at a Love’s RV Spot, we woke up to a flat rear tire. No visible puncture, nothing obvious. We refilled the tire with our trusty Milwaukee Air Pump and limped across the street to a tire shop. That’s when we got the first real clue—the aluminum wheel itself was leaking.
Not the valve. Not the tire. The wheel.
We assumed it was a fluke. Rough roads, construction zones, potholes—maybe we’d hit something that stressed the metal just enough to crack. So we attempted a repair and reinstalled it at home. After one night, it was already 12 psi low. The fix had failed.
When One Becomes Two… Becomes Three
We ordered a replacement aluminum wheel and, wisely, also purchased a steel wheel to mount the salvaged tire. With two spares, we hit the road again feeling prepared.
Until we weren’t.
Another slow leak. Another wheel cracked—this time, on the backside where the spokes meet the rim. Then it happened again. Three of our four original aluminum wheels had now failed in the same spot. Not from curb rash or collision. From travel. Wear. Stress.
And this morning? A big screw in one of the aluminum-mounted tires. With no spares left, we’re spending a couple of hours at a tire shop in the middle of our journey to the 85th Sturgis Motorcycle Rally.
Yes, we made it to Sturgis. Yes, we’re having an amazing time. And yes—we’ve officially ordered four steel wheels from eTrailer.com to replace every remaining aluminum one.
Aluminum vs. Steel Wheels for RVs: What You Need to Know
Here’s the heart of the matter: Are aluminum RV wheels worth it, or should you go steel?
Aluminum wheels look sharp. They’re lightweight, reduce unsprung weight (which can slightly improve fuel efficiency), and resist corrosion better in some climates. But they’re also more brittle. On heavy-duty, high-mileage setups like toy haulers hauling motorcycles, they’re susceptible to cracking—especially at high stress points like spoke junctions.
Steel wheels, on the other hand, are heavier. But they’re more forgiving. They bend instead of crack. They’re also typically less expensive and easier to repair or replace in remote areas.
What we’ve learned firsthand:
- Cracked aluminum wheels are hard to spot until it’s too late.
- Leaks don’t always come from the tire itself.
- Steel wheels offer peace of mind when traveling long distances under heavy loads.
We’re not saying all aluminum wheels are bad. But for us—and our use case—steel is the smarter choice moving forward.
A Final Thought: This Isn’t a Complaint. It’s Gratitude.
If it sounds like a rant, it’s not. We’ve been incredibly fortunate. Each time something went wrong, we were somewhere safe. Somewhere with a tire shop, a mechanic, or a friendly hand. We could’ve been stranded in the middle of nowhere—but we weren’t.
We’re blessed to be able to do what we love: travel, explore, and ride. And in moments like this, we’re reminded that even the most frustrating setbacks can reveal hidden blessings. That’s why we’re sharing this—not just to inform, but to remind others: God is good, and the road ahead is still full of promise.
So if you’ve dealt with cracked RV wheels—or you’re thinking about swapping your own—feel free to share your experience. You’re not alone, and your story might help someone else down the road.
