2nd Gen Dodge Ramcharger biggest tire size: stock and lifted
The biggest tire owners run on a Dodge Ramcharger (1981–1993) at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
About a 32 or a narrow 33. RamCharger Central's Elwenil says 32s fit most Ramchargers with a little rubbing or minor trimming, but the front springs tend to sag, so measure your truck. 33x10.50s on 8-inch-wide wheels are the usual safe choice. Owners disagree about 33x12.50s: one says they rub at full lock, while another ran them on every unlifted Ramcharger he owned. A member survey found 8-inch wheels work and 10-inch wheels rub. 31x10.50s clear with room to flex, and expect 33s to feel slow on stock gears.
Biggest 2nd Gen Dodge Ramcharger tire at every lift
| LIFT | BIGGEST TIRE | WHAT IT TAKES |
|---|---|---|
| Stock | 32 in (33x10.50 on 8-in-wide wheels) | RamCharger Central: 32s fit most trucks with a little rubbing or minor trimming, but sagging front springs vary, so measure. A member survey found 8-in-wide wheels work and 10-in-wide wheels rub. Owners disagree on 33x12.50s: one says they rub at full lock, another ran them on every unlifted truck he owned. |
| 3.5 in | 35x12.50 on 8-in-wide wheels | One owner reports the same light rubbing at full lock and on sharp angles that he had with 33x12.50s on stock springs. It's fine on the street. Plan on 4.10 or 4.56 gears for 35s. |
| 6 in | 37x12.50 | Skyjacker's figure for its D600BKS kit on 1975–93 Ramchargers, using wheels with 4 in of backspacing. The kit also needs a new steering or pitman arm, an adjustable drag link and longer brake lines. |

Lift kits, wheels and tires for the 2nd Gen Dodge Ramcharger
New springs fix decades of sag. Skyjacker's 6-in kit for 1975–93 Ramchargers also needs a new steering or pitman arm, an adjustable drag link and longer brake lines, and the company says it fits up to 37x12.50 tires on wheels with 4 in of backspacing.
Owners say regearing is the most important mod for bigger tires. A limited slip or locker in the 9.25 rear is the next step.
Do you need to re-gear?
Almost certainly. RamCharger Central members say most trucks came with tall gears, often 3.21:1, and Dodge's 1990 brochure lists 3.21 as standard on the 4x4 with 3.55 optional. For 33s, owners want 4.10s. For 35s, they suggest 4.10 or 4.56, and say 4.88 is too much. Overdrive automatics suffer most with big tires on stock gears.
Fitment comes from owners and specialists; wheel width, offset, trimming and bump stops change what fits. Check clearance at full lock and full flex before you buy. Some links are affiliate links.
