Project Dodge Mega Cab: Low COG 37s
Ever since Chrysler re-designed the Dodge Ram in 1994 (2nd Gen.), large wheel wells have been graciously accommodating big off-road tires. Our 3rd Gen. Dodge Ram 2500 is no different.
We knew our Ram 4x4 had room for something bigger than the stock LT265/70 R17s it came with from the factory. The real question was how big could we go before having to run a 4- to 6-inch lift.
Ideally, we wanted to stay as close to the ground as possible, yet have enough clearance to roam the desert and mountain trails without dragging axles. We are big fans of low COG (Center of Gravity) setups. The “big tires with minimal lift” approach keeps a low center of gravity and makes for a much more stable and better handling off-road vehicle.
After some digging and consulting with Dodge Ram Heavy Duty suspension experts like KORE, Carli and Thuren, we discovered that running 35- to 37-inch tires with front leveling springs would do the job. Anything bigger would require a larger lift and possibly fiberglass fenders.
Here are some key benefits of BFGoodrich All-Terrain T/A KO tires:
• Dual-compound tread and ShoulderLock technology with 40% wider shoulder grooves provide increased traction and control in aired-down driving situations
• Aggressive, high-void all-terrain tread design.
• Three-ply polyester tire delivers stiffer tread area for more precise steering response, better cornering control, excellent puncture an exceptional bruise resistance.
• Built to improve stress distribution, tread life and resistance to irregular wear.
Before getting back on the road, we used our Superchips power programmer to set the new tire diameter. This will help with transmission shift points, power, torque and MPG.

We really like the new tires. The truck actually rides a lot smoother and handles surprisingly well for this big of rubber.
Towing and hauling has also been fine. We were a little reluctant at first since we weren’t sure if the D vs. E load rating would inhibit our truck’s ability to haul/tow, or handle the heavier diesel engine weight up front. When we compared the actual max weight capacity, the BFG 37s can carry 3,525lbs. @ 50psi compared to the stock 265s rated for 3,195lbs. @ 80psi.
We’re way ahead from a load-carrying standpoint — 1,320 lbs. with all four. For serious towing, the E-rated construction is still a better choice. In our case, the D-rated tire gives us a happy medium between off-road performance and the ability to haul our Lance camper and 18-foot trailer.
Although the BFG is only a D-rated tire, we’re confident that with its three polyester, two steel, one nylon and TriGuard three-ply sidewall it will be more than enough for our needs.
We’ll come back with a long-term update to let you know how they do. Stay tuned for more project Dodge Ram Mega Cab.
