The Ford F-350 Super Duty is a Class 3 heavy-duty pickup with a GVWR up to 14,000 pounds and gooseneck towing capacity up to roughly 38,000 pounds with the right configuration. At those numbers, tires are not a secondary consideration. The F-350 requires LT (Light Truck) rated tires with Load Range E or higher — P-rated passenger tires are not appropriate for any working F-350. This guide covers the right tire categories, top-performing options, and fitment details for SRW and dually configurations.
Why Load Rating Is the First F-350 Tire Decision
Load Range E (10-ply equivalent) is the minimum practical load rating for a working F-350 that tows or hauls regularly. Load Range E tires carry 80 PSI max inflation and support load capacities of 3,000 pounds or more per tire — necessary when the truck's rear axle may be carrying over 5,000 pounds of payload on a loaded bed.
Load Range F (12-ply) tires are available in some F-350 sizes and provide additional margin for the heaviest applications — fifth wheels, gooseneck trailers, and commercial use. LR-F tires run higher inflation pressure (95 PSI typical) and provide a stiffer ride, which is the appropriate trade-off for commercial-level towing.
Using a P-rated or LT Load Range C tire on an F-350 that regularly tows near capacity is unsafe. The tires will overheat under load, wear faster, and are at risk of sudden failure. The door jamb placard specifies minimum load rating for your configuration.
Top Tire Options for the F-350 Super Duty
Highway and towing focus: the Michelin Defender LTX M/S in Load Range E is a consistent top performer for work trucks that primarily stay on pavement. It provides a quiet ride, strong wet and dry traction, and long tread life — often 50,000 to 60,000 miles with proper rotation. The Goodyear Wrangler All-Terrain Adventure and Continental TerrainContact H/T are strong alternatives in the same category.
All-terrain for mixed use: the BF Goodrich All-Terrain T/A KO2 in LT275/65R20 or LT285/65R20 is the most popular A/T option for F-350 owners who see gravel, dirt roads, and construction sites. It comes in LR-E and handles the loads an F-350 generates. The Falken Wildpeak AT3W and Cooper Discoverer AT3 XLT are solid alternatives at a lower price point.
Commercial-rated tires: Goodyear Endurance (for trailer use) and Michelin Agilis (for cargo van and commercial truck applications) are worth considering for dedicated commercial operators who prioritize load capacity and retread compatibility over ride quality.

SRW vs Dually Fitment on the F-350
The F-350 comes in SRW (single rear wheel, two tires on the rear axle) and DRW dually (four tires on the rear axle) configurations. These require completely different tires. SRW F-350s use standard LT metric or LT flotation sizing in Load Range E. Common sizes include LT275/70R18 and LT275/65R20.
Dually F-350s require dual rear wheel (DRW) rated tires for the rear positions. DRW tires have a narrower nominal width designed for dual fitment without sidewall contact between the inner and outer tires. Common dually rear sizes: LT235/80R17 or LT225/75R17. Using standard tires in a dually position is dangerous — sidewall contact causes heat build-up and failure.
Front tires on a dually F-350 are standard LT metric and can be chosen from the same pool as SRW front tires. Many dually owners match fronts to rears for consistent handling or run a dedicated highway front tire for a smoother ride on the front axle.

Frequently asked
What size tires does the Ford F-350 Super Duty use?
The most common OEM sizes are LT275/70R18 on XL and XLT models and LT275/65R20 on higher trims. Lifted F-350s run 35x12.50 or 37x12.50 depending on lift height and clearance. Dually models use different sizing entirely for the rear positions. Always verify with the door jamb placard for your specific configuration.
Do I need Load Range E tires on the Ford F-350?
Yes, for any working F-350. Load Range E (10-ply equivalent) is the minimum for towing and hauling use. The door jamb placard specifies the minimum load rating. Using under-rated tires on a truck that tows near capacity is a safety issue — not a warranty or preference issue.
How often should I rotate tires on an F-350?
Every 6,000 to 8,000 miles for a working truck. The rear tires on a loaded F-350 carry significantly more weight than the fronts when hauling, which creates uneven wear. Regular rotation is essential for even tread life. Dually owners should rotate both rear sets together with the front tires on a consistent schedule.
What is the best tire for towing with an F-350?
For primarily on-road towing, the Michelin Defender LTX M/S and Goodyear Wrangler All-Terrain Adventure in Load Range E are top choices. Both provide the load capacity, tread life, and highway comfort the F-350 needs for long-haul towing. For mixed towing and off-road use, the BF Goodrich KO2 in LT fitment is the most popular overall pick.
