The Founders 225/70R19.5 M/T gives heavy-duty trucks a direct-fit step into serious off-road traction. It keeps the factory size logic in place, including speed and weight expectations, while replacing a street-oriented tread with a more aggressive self-cleaning mud-terrain pattern.
For trucks that cannot afford to lose mobility on wet ground, snow, loose surfaces, or work sites, the 225 M/T is the cleanest entry point into the Founders lineup. No wheel change. No conversion. Just more tire.
Built to keep a working truck moving.
The 225 M/T is for buyers who want real traction gains without jumping into a larger-size tire or wheel change. Direct fit. Serious grip. No drama.
225 M/T Specifications
The 225 M/T is the direct-fit entry into the Founders mud-terrain lineup. The key questions are fitment, load, pressure, and whether the tire delivers the traction upgrade you need without changing the whole package.
Direct-fit sizing with a more aggressive tread package for trucks that still need to behave on the road.
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, in a direct-fit size.
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 on a working truck.
Transition Blocks
Bridge forces between the center zone and shoulders, balancing handling feel and reducing the harmonics that show up as road noise.
Stone Ejectors & Siping
Clear rocks from the tread, add wet-grip bite, and support winter traction, small features that make a real difference on the job site.
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.
