Tire & Wheel Fitment Guide: 2014-2026 Ram 2500/3500 with a Leveling Kit

Running a leveling kit on your 2014–2026 Ram 2500 or 3500 (4WD) opens up room for bigger tires — but Rams are notoriously tight behind the front tires and highly sensitive to wheel offset. Here's a complete breakdown of what fits, what rubs, and how to set up your truck right the first time.

Best Fit Tire Size by Lift Height

On a 2014–2026 Ram 2500/3500 with a 2", 2.5", or 3" leveling kit, the largest tire you can fit with zero rubbing is a 35x12.50 (metric equivalents: 295/65 or 315/70). Unlike Ford trucks, Rams are highly sensitive to wheel offset — the wrong offset will cause rubbing regardless of tire size.

2" Leveling Kit

Best fit: 35x12.50 on factory or high positive offset wheels.

To clear 35s on a 2" level without rubbing, you must use a wheel that keeps the tire tucked inward. Lower offsets will cause the tire to rub the rear liner and cab corner during turns. Stick to factory offset or +18mm to +27mm aftermarket wheels for a clean install.

2.5" Leveling Kit

Best fit: 35x12.50 — the sweet spot for a clean 35-inch setup.

This is the most popular configuration for a reason. A narrow 37x11.50 is possible on factory wheels with careful selection. Note: 37x12.50 tires can fit on a 2.5" level, but will rub the factory radius arms at full steering lock, or rub the body with aftermarket wheels — not recommended without modifications.

3" Leveling Kit

Best fit: 35x12.50 — clears cleanly with any wheel offset down to 0mm.

Secondary option: 37x12.50 becomes possible, but requires high positive offset wheels (+25mm to +27mm or factory) and a radius arm drop bracket or high-clearance aftermarket radius arms to avoid heavy rubbing at full steering lock.

Ram 2500/3500 Wheel Spec Guide (2014–2026)

Ram Heavy Duty trucks use an 8x6.5" (8x165.1mm) bolt pattern with a 121.3mm center bore. Because the front axle shifts slightly when leveled, choosing the right wheel spec is critical.

Setup Goal	Wheel Width	Offset Range	Backspacing	Result
No-Rub / Factory Fit (Best for 35s or 37s)	9"	+18mm to +27mm	~5.75" to 6.00"	Best overall fitment. Safely clears 35s. Keeps tires flush or slightly tucked under the fender.
Slight Poke / Flush (Minor Rub Risk)	9"	0mm to +12mm	~5.00" to 5.50"	Pushes tire out ~1". Will require trimming of the plastic inner fender liner behind the fog light with 35s.
Factory Wheels (Budget)	8" or 8.5"	+43mm to +57mm	~6.00"+	Easily clears 35x12.50, but wide tires will brush factory radius arms at full steering lock.
Aggressive Stance (Severe Rub — Avoid)	10" or 12"	-12mm to -44mm	<4.75"	Will destroy metal cab corners and plastic liners. Avoid on a leveled Ram.

Ram-Specific Tips to Avoid Rubbing

• The Radius Arm Rub: Running 35x12.50s on factory Ram wheels will cause the tire to brush the thick steel radius arms during tight turns like parallel parking or U-turns. It won't damage the tire structurally, but it will rub off paint. Aftermarket wheels with +18mm to +25mm offset eliminate this.
• Track Bar Correction: When you level a 2014+ Ram, the solid front axle is physically pushed to the driver's side. An adjustable track bar is highly recommended to re-center the axle — otherwise, your driver-side tire will rub significantly worse than the passenger side.
• Offset is Everything on a Ram: Unlike Fords, where offset is a preference, on a Ram it directly determines whether your tires rub or not. Don’t go below +18mm on a leveled Ram without planning for trimming.

Need a Radius Arm Drop Bracket?

If you’re running a 3" level or planning to run 37s on your Ram 2500 or 3500, a radius arm drop bracket corrects caster angle and provides the clearance needed to run larger tires without rubbing. Apoc Industries manufactures radius arm drop brackets specifically for the 2014–2026 Ram 2500 & 3500 — engineered and built in the USA from heavy-duty steel.
