Best FitHD pickups and work trucks that need more than a factory 225
Why It WinsHigher load rating, more width, more ground presence
Use CaseFleet, utility, fire, and severe-duty trucks

The 245 M/T is the logical evolution of the Founders 225. It gives heavy-duty trucks more height, more width, and higher weight capacity while still fitting real-world use cases that make these trucks valuable.

Compared to the factory 225 size, the 245 adds stance, flotation, and ground clearance without asking buyers to jump into a full conversion-style setup. If the 225 is the entry point, the 245 is where things get serious.

Max Load4,805 lb

The heavy-duty direct-fit upgrade.

If the 225 is the entry point into severe-use traction, the 245 is the stronger all-around step for buyers who need more tire without overcomplicating the build.

Tread Breakdown

Five zones. One purpose: keep the truck moving.

The same proven tread architecture that makes Founders tires effective in severe-duty conditions. Five zones working together to deliver traction, stability, and durability across pavement, dirt, mud, and snow.

1

Shoulder Lugs

Cornering stability and off-road bite, staggered edges cut noise without sacrificing the lateral grip that matters when terrain gets uneven.

2

Center Tread Blocks

Primary contact patch for straight-line stability, braking, and acceleration traction, the foundation of everyday usability.

3

Transition Blocks

Bridge forces between the center zone and shoulders, balancing handling feel and reducing the harmonics that turn into road noise.

4

Stone Ejectors & Siping

Clear rocks from the tread, add wet-grip bite, and support winter traction, small features that matter in real-world conditions.

5

Tie Bars & Stabilizers

Reinforce the pattern so the tread wears evenly and stays controlled on the highway without raising noise or giving up off-road performance.

The tires have been really good, got about 20,000 miles on them and still look almost new. I recommend these to anybody running an F450 or F550 truck.
