305 A/T
/70R19.5
Highway capable. Trail ready. All terrain traction in the Founders 305 footprint for trucks that do it all.
Where the 305 M/T is all-out attack, the 305 A/T plays both sides. It delivers serious off-road capability with a tread design engineered for on-highway manners, lower road noise, predictable handling, and the kind of everyday drivability a work truck actually needs.
This is the choice for fleet trucks that run paved routes but encounter unpaved conditions on the job. Fire service apparatus that needs to get there fast and get off-road when it has to. Overland rigs that live on the highway between adventures.
One tire. Every condition.
The A/T pattern is designed for the truck that doesn't have a second tire set. Highway miles Monday, job site off-road Friday, the 305 A/T handles both without compromise.

The 305 A/T performs across conditions, pavement, dirt, snow, and everything in between.
Built to carry the truck without making every road mile a compromise.
The A/T pattern is doing a different job than the 305 M/T. It still needs real off-road grip and severe-duty strength, but it also has to stay calmer on pavement, wear more evenly, and make mixed-use trucks easier to live with every day.
Shoulder Blocks
The outer blocks still give the tire real off-road bite, but they are shaped to stay more composed on pavement than a pure mud tire.
Center Traction Zone
This connected middle section helps the truck track straighter, brake more predictably, and keep road manners under control.
Transition Lugs
These bridge the center and shoulders so the tire can move between highway use, gravel, dirt, and jobsite surfaces without feeling abrupt.
Sipes & Wet Edges
Extra biting edges improve wet and winter grip, which matters for buyers who still have to run the truck in bad weather.
Stone Ejectors & Groove Guards
Help clear debris out of the tread voids and reduce the chance of rock retention when the truck leaves pavement.
Sidewall Protection
The outer shoulder and sidewall features add cut resistance and side bite without making the tire as aggressive as the M/T.

What Customers Are Saying
I absolutely love the tires! I put 6 on my F550 and used them for a whole summer. The performance whether off-road or under a heavy load towing is quite impressive!
