Tires are the one place you don't want to cut corners on an RV. A blowout at highway speed with a loaded trailer isn't just an inconvenience — it can end your trip, your rig, or worse. We've dug through real owner feedback, load ratings, and long-haul performance data to give you the short list worth considering.

Here's what's actually worth your money in 2026.

1. Goodyear Endurance The default recommendation for good reason.

If you ask any experienced RV forum what tire to run, Endurance comes up first. It's not hype — it's a genuinely well-built ST tire with consistent quality control, wide availability, and a track record on everything from weekend warriors to full-time rigs. Start here unless you have a specific reason not to.

2. Carlisle Radial Trail HD Best value for the money.

Carlisle doesn't get the same press as Goodyear but it earns it on the road. Real owners running 30,000+ miles on these tires. If you're watching your budget without wanting to compromise on a critical component, Radial Trail HD is the move.

3. Maxxis M8008 The quiet workhorse.

Consistently recommended for 14" and 15" setups where Goodyear sizing gets tricky. Maxxis builds a tight, well-balanced ST tire that runs cool and handles highway miles without drama.

4. Cooper Hercules (H-Series) New competition for the top spot.

Rated comparably to the Endurance but typically priced lower. Relatively new to the RV market, so the long-term data is still coming in — but early feedback is strong. Worth considering if Goodyear is backordered or out of your size.

5. Sailun S637T The long-haul sleeper pick.

Not the flashiest name on this list, but owners running their second set with zero complaints. If longevity and smooth highway feel matter more than brand recognition, Sailun deserves a serious look.

6. Hankook Vantra Trailer ST01 Purpose-built for trailer duty.

Engineered specifically for trailer loads — not adapted from a passenger tire profile. Solid durability numbers and a trailer-specific sidewall design that handles sway better than generic alternatives.

7. BFGoodrich All-Terrain T/A KO2 When the pavement ends.

Not an ST tire — this is a light-truck rating for rigs that see gravel forest roads, BLM land, or anything rougher than a KOA. If your adventures take you off the highway regularly, the KO2 earns its price premium.

8. Michelin Defender LTX M/S Premium pick for light-truck applications.

Michelin's reputation holds up here. The Defender LTX is a top-tier LT tire for Class B and smaller Class C rigs where you're running truck or van-based wheel specs. Pricey, but it shows in the ride quality and longevity.

9. Goodyear Wrangler Workhorse AT Balanced all-arounder.

Highway manners of a touring tire, light off-road capability when you need it. A good middle-ground LT option if the KO2 feels like overkill but you still want something tougher than a standard highway tire.

10. Continental VancoFourSeason The Class B specialist.

Built for high-roof vans and designed to handle all-season highway conditions without fuss. If you're running a Sprinter, Transit, or ProMaster conversion, this is the tire most often spec'd by the builders who know these platforms best.

Bottom Line

For a travel trailer: start with the Goodyear Endurance. If it's out of stock in your size, Carlisle Radial Trail HD or Maxxis M8008 are honest alternatives, not consolation prizes. For truck-based rigs going anywhere interesting, the BFGoodrich KO2 is the tire we'd choose without much debate.

Replace your tires before you think you need to. Every experienced full-timer will tell you the same thing.
