Quick answer: the right all-terrain tires for 1 ton dually trucks depend on your wheel size and load needs before tread. Both picks here are 35×12.50R20 aftermarket sizes. The Prinx HiCountry A/T2 (load range F, snowflake-rated) is the more traditional all-terrain, while the Venom Power Terra Hunter XT is a more aggressive extreme-terrain tire. Neither is a typical factory dually size, so confirm wheels and clearance before you order.

More Details on Our Top Picks
Venom Power Terra Hunter XT Mud Tires (2-Pack)
The Terra Hunter XT is an extreme-terrain tire that sits closer to a mud-terrain than a typical all-terrain. This 35X12.50R20LT size is load range E (10-ply) with a 121R load index, about 3,195 lb per tire. Retailer pages stress mud and off-road traction and call it year-round, but the pages we checked do not list a snowflake rating, tread depth or warranty terms. It is not a factory dually size, so confirm your wheels, clearance and any lift before ordering. The Amazon title says 2-Pack, and a dually runs six tires, so plan the quantity.
- Tire Size:35X12.50R20LT
- Load Index / Range:121R, load range E (10-ply)
- Approximate Max Load:3,195 lb per tire (from the standard load-index chart)
- Terrain Type:Extreme terrain
- Snow Rating:Not listed
- Warranty:Not confirmed
Pros
- Load range E with a 121R load index

Prinx HiCountry A/T2 All Terrain LT35/12.50R20 125S F Light Truck Tire
The HiCountry A/T2 in LT35/12.50R20 is a true all-terrain with multi-step tread blocks. It is load range F (12-ply) with a 125S load index, about 3,640 lb per tire. Retailer pages list the three-peak mountain snowflake symbol, a 16/32 in. tread depth, an approved rim width of 10 to 12 inches and a 50,000-mile treadlife warranty. At 35 inches tall, it is an oversize aftermarket choice for most duallys, so check clearance and gearing. Check the Amazon listing for how many tires come in the order.

How to Choose All-Terrain Tires for 1 Ton Dually
Start with the size and load information on your door-jamb placard and in the owner’s manual, then decide how much off-road and winter grip you need.
Fit Checklist Before You Buy
- Read the factory tire size, load index and wheel size on the placard. Some factory dually sizes are smaller and narrower than 35×12.50, such as 17-inch and 19.5-inch sizes on some models.
- Match the wheel diameter. Both tires here need 20-inch wheels.
- Check wheel width against the tire’s approved rim width range.
- Check clearance in the wheel wells and between the dual rear tires, and plan for a lift or other changes if needed.
- Expect speedometer and gearing changes with an overall diameter near 35 inches.
- Buy the right quantity: a dually has six tires.
Load Range and Load Index
Load range E and F are heavy-duty construction. The load index tells you the weight each tire can carry at its maximum pressure: 121 is about 3,195 lb and 125 is about 3,640 lb. Many LT tires list a separate load rating for dual-wheel use on the sidewall, so check it against your axle rating. Check your axle and GVWR ratings in the owner’s manual, and do not use a tire below the original load capacity.
Matching Tires on Dual Rear Wheels
Both tires in a dual pair should match in size, model, load rating and wear, and be inflated equally. A smaller or underinflated tire makes its partner carry extra load. Ask a tire shop to check that the paired tires are within an acceptable diameter difference.
Tread Pattern and Snow Rating
More aggressive tread helps in mud and loose ground but is usually louder and wears faster on pavement. For winter driving, look for the three-peak mountain snowflake symbol. Retailer pages list it for the Prinx HiCountry A/T2 but not for the Venom Terra Hunter XT. For more snow-focused options, see our guide to all-terrain tires for snow.
Warranty
Treadlife warranties usually cover tread wear only and often require regular rotation and correct pressure. Read the terms from the seller or manufacturer before you buy. The Prinx lists 50,000 miles with the retailer we checked. We could not confirm terms for the Venom.

Frequently Asked Questions
Can I run all-terrain tires on the front and mud tires on the rear?
It is not recommended. Mixing tread patterns changes traction balance and handling, and on a 4WD truck mismatched diameters can strain the drivetrain. Use the same size and model on every axle where possible, and always match both tires of each dual pair.
Do the two tires in a dual pair need matching load ratings?
Yes, they should match. Each tire must meet or exceed the load required for its position, and a dual pair should match in size, model, load rating and inflation so that neither tire carries more than its share.
How often should I rotate tires on a 1 ton dually?
Many tire makers suggest about every 5,000 to 7,500 miles, but dually rotation patterns differ from a single-wheel truck. Follow your owner’s manual and ask a tire shop about the right pattern.
Will all-terrain tires affect towing stability on a dually?
They can have a modest effect. Aggressive, tall-lug tires flex more and can feel less precise than highway tires. Correct load-rated tires, correct pressure and a proper alignment matter most for towing stability.
Do I need different tire pressures when empty and loaded?
Often yes. The door placard pressure is for the original tires, so with a different size or model use the tire maker’s load-inflation table for your actual axle weights, and weigh the truck loaded if you can.
Will 35×12.50R20 tires fit a 1 ton dually?
Only with the right setup. It is an oversize aftermarket size that needs 20-inch wheels with a suitable width, enough wheel-well and dual-spacing clearance, and often a lift. Check with a tire shop before you buy.
Which Tire Should You Buy?
- Winter driving and heavy loads: Prinx HiCountry A/T2, load range F, with the snowflake symbol listed.
- Mud and loose ground: Venom Power Terra Hunter XT, load range E, if you do not need a confirmed snow rating.
Before either, confirm the wheel size, clearance and quantity for your dually.
