The Founders 305 A/T

The perfect balance between rugged capability and everyday usability.

Designed for drivers who need reliable traction on dirt, gravel, and snow without sacrificing highway comfort, the Founders A/T combines a stable footprint with a refined tread pattern that runs noticeably quieter than an M/T. Its broad shoulder blocks and interlocking center ribs provide excellent grip and steering response, while siped tread elements improve wet-weather handling. Built on the same heavy-duty carcass as the M/T series, the 305 A/T offers durability and load capacity for serious work applications—but with smoother road manners and reduced noise on long hauls.

Tire Tread Block Regions

All-Terrain Tread Zones

Green — Shoulder Block

Outer tread blocks for cornering grip and lateral traction on dirt, gravel, or snow.

Blue — Intermediate Lug

Balances off-road traction and highway comfort; connects shoulders to center ribs for even wear.

Brown — Stone Ejector / Groove Guard

Prevents rock retention and casing damage while keeping voids clear for consistent traction.

Purple — Serrated Sidewall

Protective sidewall ridges add side-bite and puncture resistance in rocks and ruts.

Maroon — Center Traction Block

Main contact zone for braking and acceleration; optimized for wet grip and quiet highway manners.

Navy — Siping

Fine slits that add micro-edges for wet, icy, or snowy traction while lowering heat buildup.

Red — Outer Shoulder Lug

Extreme edge traction for mud or deep snow; stabilizes the tire in aggressive cornering.

Teal — Transition Lug

Bridges sidewall and tread zones; reinforces shoulder and helps eject mud or debris.

FEATURES

Founders M/T Super Singles are designed and built for a specific purpose; to allow Ford F-450/550, Dodge Ram 4500/5500, and similar trucks to maintain their intended GVW with a super single tire while also providing superior longevity compared to any other tire its size. It features a tread design optimized for clearing mud/sand/snow while keeping enough rubber on the road to prevent overheating and premature failure.

Specific Models:

  • Ford F450/550, 2005+
  • Dodge 4500/5500, 2005+
  • GM 4500/5500/6500
  • Any truck whose stock tire size is 225/70R19.5 (and/or fits a 245/70R19.5)

Aggressive Tread When You Need It, Highway Comfort When You Don’t

The outer lugs have staggered shoulders to dig in when it’s wet. The side lugs alternate in height and are long, giving you 70% more traction in the mud. On the road, the center two rows are engineered for stability at speed and to give the tires a longer wear life.

LIFT KIT INSTALLATION GUIDE

FAQ

No, in order to fit Founders M/T onto your truck, you will need to install a lift kit as well as trim your fenders. We offer Tuff Country® lift kits as an option for each set of tires we sell, for Ford® trucks, meaning the lift kit and tires will ship together as a complete super single conversion kit. If you have a Dodge® or other make truck, you’ll have to purchase your own 2.5” lift kit separately.

The life of your tires will depend on many factors, including your vehicle weight, percentage of driving on/off road, and your style of driving. They were engineered to provide the best combination of longevity, traction, and durability.

  • Added chassis/suspension clearance over ground obstacles.
  • Tread pattern designed for superior traction in soft or muddy ground, plus improved wet and snowy road grip.
  • Extra width provides flotation in sandy or soft conditions.
  • Reinforced sidewalls resist abrasion and punctures.
  • Single tires eliminate debris jamming between duals and prevent blowouts.

Absolutely. You’ll need basic tools: wrenches, a floor jack, and some anti-rust lube for stubborn parts. No welding required. A motivated DIYer with a helper can complete the job in a weekend. Order your Founders tires pre-mounted on powder-coated wheels to save time, or have them installed by one of our certified dealers or your local mechanic.

No. Neither the tires nor the lift kit affect your manufacturer warranty in any way.

Yes. The 305/70R19.5 was engineered for super single conversions on F-450/550, RAM 4500/5500, GM, and Isuzu chassis. Pair them with proper 19.5″ wheels and the correct offset for your setup.

The 305 is wider and taller, giving more ground clearance, better flotation, and a more aggressive stance while maintaining the same self-cleaning M/T tread that defines Founders performance.

The Founders 305 M/T is engineered for severe-snow traction and carries the Three-Peak Mountain Snowflake (3PMSF) rating where molded on the sidewall. Always verify the symbol on your tire to confirm certification.

Yes, with care. Clearance depends on your wheel offset, fender liner, and brake package. Test-fit chains on a lifted, secure vehicle and check inner/outer clearance through full steering travel before use.
