Startup company creates first-of-its-kind tire blowout protection system

Tire blowouts—the bane of towable RVing. Far too many of us have found ourselves disabled on the side of the road with a mangled tire. The lucky ones get away with no damage, but from personal observation, this is rarely the case. At the very least you’ll experience torn fenders, but many suffer catastrophic damage to their trailer.

RV-DE-FENDER™ is a brand-new company in the RV accessory industry, and its revolutionary product is the first of its kind. Their patented blowout protection system is easily installed on a variety of trailers, mitigating all the devastation that normally occurs. Instead of treating blowout damage as a reality of RV life, RV-DE-FENDER has innovated a way to cease the frustration once and for all.

Here’s a closer look at the technology, including how it’s constructed, how it works, and how much you can expect to pay once the product hits the market.

What problems does the RV-DE-FENDER solve?

While blowout damage is by itself a major issue, it tends to come with a long list of auxiliary problems that make the experience that much more frustrating. By stopping the damage in the first place, RV-DE-FENDER has the potential to drastically reduce RVer headaches.

Dealing with insurance after a blowout can be a nightmare. While a decent policy should cover you during this event, there are occasionally caveats. Overloading and aged tires can both be reasons for an insurance company to deny your claim, leaving you to foot the bill. In my personal experience, insurance claim specialists aren’t normally this scrutinous, but it’s still a valid concern.

If you are fortunate enough to receive coverage after your blowout, finding an RV shop to do a timely repair is nearly impossible. Many stories have been written here on about the extensive time it can take to get your RV serviced. Preventing the damage in the first place is your best option.

Finally, with RV-DE-FENDER, a tire blowout doesn’t have to be a trip-ruining experience. Dealing with it can be as simple as jacking up your axle and switching the tire out with the spare.

A look at the construction and how it works

RV-DE-FENDER is a tire blowout protection system
RV-DE-FENDER Installed on a Trailer Axle

The RV-DE-FENDER is made of durable cold-rolled steel and is manufactured in the founders’ home state of Utah. The product features a 1/8’’ backing plate that protects the inside of the wheel well and mounts around the axle. The main protective feature is the steel arch that surrounds the tire.

According to EIN News, the product works in three distinct ways:

  1. Protecting the wheel well against the initial explosion caused by a tire blowout
  2. Containing the flying debris within the guard so that fenders, trailer subfloors, and wheel components are not damaged
  3. Providing “peace of mind” to the RVer that a blowout won’t cause detrimental damage

In 24 separate trailer tests, the RV-DE-FENDER performed flawlessly every single time.

Purchase price and trailer compatibility

According to one of RV-DE-FENDER’s founders, Zack Patterson, product pricing will be dependent on the tire size, as well as the number of axles. Single axle trailers will start at $800 per package, which includes a guard for each tire. Triple axle trailer packages will retail for around $2,500.

The company’s intention is to make its product compatible with most trailer types. For now, they’re primarily focused on 3,500 lb. axles with 10-inch drum brakes and 5,000 to 7,000 lb. axles with 12-inch drum brakes. The RV-DE-FENDER currently comes in two sizes: one fits 14- and 15-inch tires, and one fits tires up to a 235/85-16.

Ideally, the company wants to partner with RV dealerships to offer their product as an add-on for new RV purchases. They’re also looking to develop a network of certified mechanics who can install their product onto customers’ rigs.

A big advantage is that the RV-DE-FENDER can be easily installed by oneself. Installation requires the removal of the wheel and brake drum in order to access the mounting points. Fender trimming may also be necessary.

Final thoughts

RV-DE-FENDER is still in its infancy as a company, having only earned its patent and trademark in September of 2022. As of now, purchases are not available on the website.

However, the innovation and problem-solving set forth by the company are admirable and have immense potential. It will be interesting to see where the company goes in the future, and how the overall industry will react to the product’s quality and efficacy once it hits the mainstream market.

I had a tire blow out, tore out wheel well and it just so happen to be where one of the main wiring harness ran. It grabbed it and pulled wiring from every direction. Locked up the tire and small fire. I was back on road with a spare,magnetic lights within an hour. This was the following season after I put a new floor in. Ahh camping, so relaxing.

I have repaired trailers from this kind of damage. Even huge commercial trailers.
This design might save you damage one out of 4 blow outs. Here is why.
With this design the clearance from the tire, to the fender, on the rear side of the fender, is so close that when your tire blows the rubber will be whipping upward off the tire on that bottom edge of the fender and grab it and rip it to pieces every time.

The centrifugal force on that edge is tremendous. I have seen it bend heavy beams on commercial trailers.

I have custom built far better ones and provide a horizontal surface there so as not to have an edge for the rubber to grab. It slaps there before continuing up and around in a clockwise manner.
Do not waste your money on this design.

When I saw a video on this new product i contacted them to learn more facts and to not make guesses. The videos i have seen show a number of different tire failures and almost no damage to the trailer (minor scuffing on fiberglass fender). Weight 25 – 33# per unit. Since the unit fits onto the axle it will not fit all RVs but the company is collecting information on which RV it does fit. I will be writing more for my RVTravel weekly column. This item does look very promising.

Per unit? Is that per wheel or per axle?

What a concept, putting fenders BACK onto trailers. Steel protective fenders used to be on EVERY vehicle until manufacturers started cheapening things up with plastic. Now we have to pay extra for old technology.
The photo looks as though the clearance between steel and tire would fill up pretty quickly with debris.

To expensive, I’m sure there is ways cheaper to design a fender well that won’t distruct. When you have a blowout and built into the RV when manufactured. After all you never hear of cars being damaged by blowouts.

How about the RV industry just building wheel wells the way they should in the first place at the factory instead of leaving a critical area of the RV so flimsy and exposed to severe damage. They could keep the cheap fireplaces and blue string lights and put that cost toward a real quality build instead. But then, RV consumers don’t look at or ask about wheel well build but oooh and aaaah over flashy trinkets.

I recently costed out the addition of an inner fender liner using a tandem trailer treadplate bolted to 4″ square tubing which in turn is bolted to the frame using self tapping screws. This placed the fender below the slides and just inside those fake plastic wheel fenders. Looks like the RV-DE-FENDER would require a similar clearance inside the plastic fenders so a shredded tire would most likely take these out. My total cost of materials (in the cart on ebay): $250 for each side including the fenders, square tubing, shipping, self-taping bolts, primer, undercarriage rust-prevention coating & under coating.

So, $500 vs $800 X 4 ($3,200). That & I have serious issues with the RV-DE-FENDER bolted to the axle instead of the frame.

And then there are clearance issues above the RV-DE-FENDER as the springs are compressed forcing the top of the bouncing fender up into the trailer body above.

Thanks, Tom. This was my first thought as I read about the product and was figuring in my head what could be done pretty easily with a much lower cost commercially available steel trailer fender.

$3200? It’s $800 per axle.

OK, $500 for a solidly mounted 10″ wide inner fender with clearance for 16″ tires and fully protect the autoleveling mechanism front and rear of the tires vs. $1,600 for an as yet questionable, unproven application (bolted to the axle ends with 5 bolts that support the brake backing plate?), the large fender housing taking a direct beating from every pothole and uneven bridge seams & expansion joints. I remain skeptical.

agree on the weight concerns, as in will people offset the added weight? two more concerns are corrosion and well packing.

how are these inner fenders protected from corrosion? no coating is going to stand up to the pelting of road pebbles and the like. will routine bearing and brake maintenance have to expand to anti-corrosion treatment to the inner fenders?

these inner fenders will reduce space around the tires. have the units been tested for driving in snow and slush? not that any of us want to drive in such road conditions,sometimes there is no choice. I’ve been caught with a choice of driving out of a storm or risk getting snowed in place for several days.

Add mud to the equation. JJ’s last paragraph is quite, hmmm? You never when mother nature forces something unexpected.

Sounds like a great invention, as we have experienced 3 blowouts on our Lance in the past
4 years. Fortunately we suffered no damage to our well built trailer. My concern is that these steel protection collars will add weight to the trailer, effectively reducing the overall carrying capacity of your unit. And isn’t overloading the major reason for blowouts in the first place? Now one will have to put less stuff in their rig. I don’t see that happening!

Great point on added weight. It’s not an issue for our 5th wheel which has 2700 carrying capacity due to it’s 7000 lb axles and 12″ frame. Based on a recent scale check, we use up less than half of that with all the “crap” we haul around. So it’s a balance of preventing blowout protection & repair cost against the increase in weight and reduced carrying capacity and slight decrease in fuel mileage.

We had steel plates added to the top of all four trailer wheel wells some time back. Not as fully protected as these look, but better than nothing. I hope to never have to report whether our additions work.

‘Down the road’, hopefully, they can develop a package for the dualies on a class-C.
