More load. More width. More flotation. The heavy-duty direct-fit step up for buyers who need more truck under them.

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.
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.
245 M/T Specifications
The 245 M/T is the heavier-duty direct-fit step up. It adds more tire under the truck without pushing the buyer into a full fitment-driven build path.
More tire, more load, more confidence, without forcing a full conversion build.
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.
Shoulder Lugs
Cornering stability and off-road bite, staggered edges cut noise without sacrificing the lateral grip that matters when terrain gets uneven.
Center Tread Blocks
Primary contact patch for straight-line stability, braking, and acceleration traction, the foundation of everyday usability.
Transition Blocks
Bridge forces between the center zone and shoulders, balancing handling feel and reducing the harmonics that turn into road noise.
Stone Ejectors & Siping
Clear rocks from the tread, add wet-grip bite, and support winter traction, small features that matter in real-world conditions.
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.

FleetThe 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.
