1st Gen Dodge Ramcharger biggest tire size: stock and lifted
The biggest tire owners run on a Dodge Ramcharger (first generation) at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
Dodge's largest factory option was a 10-15LT, which the 1978 Macho package used. On Bring a Trailer, listings that mention no lift mostly show 31x10.50R15s. One Top Hand truck ran 32x11.50s, and a 1978 Trail Duster sold on 33x12.50R15s. On a later Ramcharger with the same Dana 44 and leaf-spring layout, an owner found 32x11.50s rubbed when the suspension twisted up. So call 31s safe and 32s the practical limit, and plan on an add-a-leaf or lift before you try 33s off-road.
Biggest 1st Gen Dodge Ramcharger tire at every lift
| LIFT | BIGGEST TIRE | WHAT IT TAKES |
|---|---|---|
| Stock | 31x10.50R15 | The usual size on BaT trucks whose listings mention no lift. Some run 32x11.50 (a 1978 Top Hand) or even 33x12.50 (a 1978 Trail Duster). On a later Ramcharger with the same Dana 44 and leaf layout, 32x11.50s rubbed at full articulation. |
| 2 in (add-a-leaf) | 33x12.50 | Off-Road.com advice for a later Ramcharger on the same axle and spring layout. A 4 in lift is suggested if you want to keep the flex. |
| 4 in | 33x12.50 | The maximum Tuff Country recommends with its 4 in EZ-Ride kit (front springs, rear add-a-leafs and 2 in blocks, plus a steering block). |
| Lifted (amount not stated) | 35x12.50R17 | A 1974 4-speed sold on BaT with Skyjacker leaves, Fox shocks and 17 in beadlocks. Crossover steering is worth considering at this height. |
