A fifth wheel puts a lot of weight on each tire, and that load sits there for hours of highway heat, scale-line stops, and long climbs. The wrong tire on a heavy 5th wheel does not just wear fast, it can fail in a way that tears up your fenders, brake lines, and underbelly. That is why a true Special Trailer (ST) tire with the right load range matters far more here than it does on a light pop-up or utility trailer.
We focused on tires that real 5th wheel owners run hard, judging them on load capacity, heat and speed rating, tread life, sidewall strength, and how they hold air over a season of storage. Below are seven RV tires for 5th wheel trailers worth your money, ranked best first, with an honest weakness called out for each one so you know exactly what you are buying.

1. Goodyear Endurance ST Trailer Tire: Best Overall
The Goodyear Endurance is the tire most experienced 5th wheel owners reach for when they want to stop thinking about blowouts. It is a genuine ST design rather than a passenger casing dressed up for trailers, and the Durawall sidewall shrugs off the curb hits and gravel-shoulder scuffs that destroy cheaper tires. The 65 mph speed rating and cooler-running compound are the real story here, because heat is what kills trailer tires, and this one handles a long interstate haul in summer better than almost anything in its class.
The honest weakness is value sensitivity and size availability. It is one of the costlier options, and if your rig runs an oddball size you may not find the exact fitment in this line. But for the most common 5th wheel sizes in Load Range E, the Endurance earns its reputation. It holds air well over winter storage and gives you the kind of confidence that justifies buying a matched set rather than chasing a deal.
- Built specifically as a Special Trailer tire for heavy 5th wheel loads
- Durawall technology resists cuts and curb scrubs on the sidewall
- Scorch-shield construction helps it run cooler at sustained highway speed
Pros: Excellent heat resistance for long towing days; Made in the USA with strong real-world reliability reports; High load range options for tandem and triple axle rigs
Cons: Sits at the premium end of the trailer tire market; Limited size range compared to some commodity ST tires
2. Carlisle Radial Trail HD ST Trailer Tire: Best Value
The Carlisle Radial Trail HD is the tire we recommend when someone wants most of the premium experience without paying for the badge. It is a proper radial ST tire with a deep, even tread that resists the cupping and feathering that plagues budget trailer rubber. In Load Range E it carries enough weight for a heavy tandem or triple axle 5th wheel, and the wide size availability means most owners can find an exact match for their rig.
Where it gives ground is at the extreme end of heat and speed. Push it hard on a long, hot grade with a fully loaded rig and it simply does not run as cool as a Goodyear Endurance. Keep your speed sensible, check pressures cold before every trip, and the Radial Trail HD delivers reliable, long-wearing service that makes it the smartest balance of capability and value on this list.
- Full-depth radial design built for long trailer mileage
- Available in Load Range D and E for medium and heavy 5th wheels
- Tread pattern engineered to reduce irregular and feathered wear
Pros: Strong load capacity for the money; Even tread wear over the life of the tire; Widely available in common 5th wheel sizes
Cons: Not as cool-running as the top premium tires on extreme hauls; Sidewall is solid but less cut-resistant than a Durawall design
3. Maxxis M8008 ST Radial Trailer Tire: Best Tread Life
Maxxis built the M8008 for owners who measure a tire by how many seasons it lasts, and it shows. The double steel belt construction and high-tensile body ply give it a tough, stable footprint that holds shape under the constant load a 5th wheel puts on it, which translates directly into long, even tread life. If you put serious miles on a heavy rig every year, this is one of the few ST tires that genuinely earns a reputation for going the distance.
The trade-off is a firmer ride and occasional availability gaps. That stiff, durable casing transmits a bit more road into the frame than a softer tire, which matters more for the cargo and cabinets inside than for traction. And because it has a loyal following, the popular Load Range E sizes can sell out in spring. Order ahead of your season and the M8008 rewards you with years of dependable service.
- Double steel belts for puncture resistance and stability under load
- High tensile strength body ply supports heavy 5th wheel weights
- Optimized tread compound for long, even wear over many miles
Pros: Outstanding tread longevity; Strong belt package resists road-hazard punctures; Stable, predictable handling on tandem axles
Cons: Stiffer ride than softer-compound trailer tires; Can be harder to find in stock during peak RV season
4. Westlake ST Radial Trailer Tire: Best Budget Pick
The Westlake ST Radial is the value workhorse for owners who replace tires on a schedule rather than waiting for failure. It is a competent ST radial with a nylon overlay that helps it stay stable at trailer speeds, and in Load Range E it carries respectable weight for a mid-size to heavy 5th wheel. For seasonal campers who do not rack up huge annual mileage, it covers the job without straining the budget.
Be honest with yourself about its limits. It does not have the heat headroom or the tread longevity of the Goodyear or Maxxis, so it rewards conservative speeds and disciplined pressure checks. Treat it as a tire you proactively rotate out every few seasons, keep it properly inflated and out of direct sun during storage, and it delivers safe, dependable service at a price that lets you replace the whole set at once.
- Nylon overlay construction for added high-speed stability
- Available in popular 5th wheel sizes and load ranges
- Solid everyday load capacity for the price point
Pros: Strong load rating relative to its budget position; Good availability in common sizes; Holds pressure well between trips
Cons: Shorter expected tread life than premium brands; Less heat headroom on long, hot highway runs
5. Trailer King ST Radial II Trailer Tire: Best Everyday Hauler
The Trailer King ST Radial II is a no-drama everyday tire for owners who tow regional trips and want predictable behavior without paying premium money. The double steel belt and center groove tread give it stable manners and decent water evacuation, which is more than many budget trailer tires offer. In Load Range E it handles common heavy 5th wheel weights, and its wide availability makes buying a matched set of four or six painless.
Its ceiling is tread life. This is a solid mid-tier tire, not a long-haul mileage champion, so a full-time RVer covering big annual distances will replace it sooner than a Maxxis. For the weekend and seasonal hauler, though, that is a fair trade. Keep up with cold pressure checks and avoid sustained high speed, and the ST Radial II quietly does its job season after season.
- Double steel belted casing for load stability
- Center groove tread channels water away on wet highways
- Shoulder design built to resist uneven wear
Pros: Stable handling under typical 5th wheel loads; Good wet-weather grooving for a trailer tire; Widely stocked and easy to match in sets
Cons: Mid-tier tread life rather than long-haul longevity; Sidewall lettering and finish feel basic
6. Freedom Hauler ST Radial Trailer Tire: Best Heavy-Duty Sidewall
The Freedom Hauler ST Radial is the pick for owners of the biggest, heaviest 5th wheels, especially triple axle rigs that flirt with the upper end of their tire ratings. Its reinforced sidewall and Load Range E and F options give you real headroom on weight, and that stiff casing fights the sway and sidewall roll that lighter tires allow when a heavy nose load shifts in a crosswind. If your scale tickets make you nervous, this is the tire that buys back some margin.
The honest caveat is a firm ride and a shorter track record. All that load capacity comes from a stiff, heavy build that transmits more of the road into your frame and cabinets, and the brand does not have the decades of independent failure data that a Goodyear carries. For a maxed-out heavy rig where load rating is the priority, it makes sense. For a lighter 5th wheel, you are paying a ride penalty you do not need.
- Reinforced sidewall for high-load triple axle rigs
- Load Range F options for the heaviest 5th wheels
- Steel belted construction for stability under weight
Pros: Very high load capacity for big rigs; Stiff sidewall resists sway and roll; Available in tough Load Range F
Cons: Firm ride from the heavy sidewall; Fewer independent durability reports than legacy brands
7. Trailer King RST ST Radial Trailer Tire: Best for Seasonal Use
The Trailer King RST is built with the seasonal owner in mind, the rig that sits in a yard or under a carport for months and then gets pulled out for a few big trips. Its weather-resistant compound is meant to fight the sidewall checking and cracking that kills tires which die of age rather than miles, and the all-steel belt package keeps it stable under a mid-weight 5th wheel when you do hit the road.
It is not a performance tire, and it does not pretend to be. The speed headroom is modest and the longevity will not match a dedicated high-mileage casing, so a full-timer covering big annual distances should look higher up this list. But for the camper who tows a handful of trips a year and needs a tire that survives storage as well as the highway, the RST is a sensible, dependable choice that holds air and resists age better than most in its tier.
- All-steel belt package for load stability
- Compound formulated to resist weather checking during storage
- Tread design aimed at consistent, even wear
Pros: Resists sidewall cracking during long storage; Reasonable load capacity for mid-weight rigs; Easy to source in common sizes
Cons: Lower speed headroom than premium tires; Not ideal for high-mileage full-time RVers
Frequently Asked Questions
What load range do I need for a 5th wheel tire?
Most heavy 5th wheels need Load Range E, and the largest triple axle rigs often need Load Range F. The right answer depends on your loaded axle weight, not a guess. Weigh your fully loaded rig at a truck scale, divide by the number of tires, and choose a tire whose maximum load rating at its rated pressure comfortably exceeds that per-tire weight, ideally with a margin of 10 to 20 percent. Running a load range that is too low is the single most common cause of 5th wheel tire failure, so when in doubt, size up rather than down.
Should I use ST tires or LT tires on my 5th wheel?
For most 5th wheel owners, Special Trailer (ST) tires are the correct choice because they are engineered with stiffer sidewalls to handle the vertical load and sway of a towed trailer rather than the steering and braking forces of a drive axle. ST tires resist the sidewall roll that causes sway in heavy rigs. Some owners with very heavy or high-mileage setups switch to LT tires for a softer ride and higher speed rating, but that requires careful load and inflation matching. If you are not sure, stay with a quality ST tire in the correct load range.
How long do 5th wheel RV tires last?
Trailer tires usually age out before they wear out. Even with good tread remaining, most experts recommend replacing RV tires every three to five years regardless of mileage, because the rubber degrades from heat, sunlight, and ozone while the trailer sits in storage. Check the four-digit DOT date code on the sidewall to confirm the manufacture week and year. If your tires show any sidewall cracking, bulging, or are past five years old, replace them as a set before your next big trip, even if they look fine.
What tire pressure should I run on a 5th wheel?
Inflate to the pressure that matches your actual loaded weight, using the tire manufacturer load and inflation table, and never exceed the maximum pressure stamped on the sidewall. Always check pressure cold, before you drive, because heat from rolling will raise the reading and give you a false number. Underinflation is dangerous on a heavy 5th wheel because it builds excess heat and is a leading cause of blowouts. A TPMS that monitors each tire while you tow is one of the best safety upgrades you can make.
Do I need to replace all the tires at the same time?
It is strongly recommended to replace 5th wheel tires as a complete set, or at minimum as a matched axle pair. Mixing tires of different ages, brands, or wear levels on the same trailer creates uneven load sharing, which stresses the older or smaller tire and increases failure risk. Because trailer tires age out together, when one fails from age the others are usually close behind. Buying a full matched set also keeps the speed and load ratings consistent across every position, which is exactly what a heavy towed rig needs.
Our Verdict
For most 5th wheel owners, the Goodyear Endurance ST is our top pick because it combines a true Special Trailer design, cool-running construction, and a tough Durawall sidewall into the most reliable heat and load package on this list, which is exactly what a heavy towed rig demands on long summer hauls. Our runner up is the Carlisle Radial Trail HD, which delivers most of that even-wearing, high-load capability at a friendlier price and in wider size availability, making it the smartest balance of capability and value. Whichever you choose, buy a full matched set, weigh your rig to confirm the load range, and check pressures cold before every trip.
