RAM 1500 Wheel Size & Specs

Depending on trim and year, most RAM 1500 models use 17 – 22 inch wheels.
Mechanic’s tip: 17″ or 18″ wheels are best for comfort, while 20″ – 22″ add sportier handling and appearance.

All 2002 – 2025 RAM 1500 trucks use a 5 × 139.7 mm (5 × 5.5″) bolt pattern.
Tip: Check stud thread M14 × 1.5 before ordering aftermarket lug nuts.

Modern RAM 1500 models (2019+) have a hub bore of 77.8 mm.
Tip: If you install aftermarket wheels, use hub centric rings 77.8 → your rim bore for perfect fitment.

22 × 9 in rims, offset ET19, 5 × 139.7 PCD, 77.8 mm center bore.
Tip: Factory Goodyear 285/45R22 tires fit flush with the fenders — no spacers needed.

18 × 8 in or 20 × 9 in rims depending on package.
Tip: If switching to 20s, use 275/55R20 tires to maintain speedometer accuracy.

17 × 7 in (Tradesman), 18 × 8 in (Bighorn), 20 × 9 in (Laramie), 22 × 9 in (Limited).
Tip: Offset ranges ET18 – ET25 — stay within this to avoid rubbing.

Factory options include 18″, 20″ and 22″ rims with PCD 5×139.7.
Tip: The 19+ generation has a larger hub bore than the older DS model — don’t mix without adapters.

OEM offset ≈ ET19 on 20×9 wheels.
Tip: Lower offset (ET0 – ET12) gives a more aggressive stance but may poke past fenders.

17×7 or 20×8 rims with 275/60R20 tires optional.
Tip: 20″ OEM chrome rims weigh ~14 kg each — heavier but strong.

5 × 139.7 mm with M14 × 1.5 studs.

77.8 mm.

Tip: Adapters can help but affect track width and bearing wear.

Approx. 68.1″ (1730 mm) front / 68.3″ rear.
Tip: Changing offset alters effective track — keep difference under 10 mm per side.

Tip: These can be upgraded to 305/55R20 with minor trimming.

20×9 rims, ET19, PCD 5×139.7, 77.8 bore.

Tip: Smaller diameters improve grip and reduce replacement cost.

77.8 mm.
