Jeep CJ-8 Scrambler biggest tire size: stock and lifted
The biggest tire owners run on a Jeep CJ-8 Scrambler at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
Jeep-CJ.com members put 31-inch tires as the safe maximum on a stock CJ. They say 32s rub the rear wheel wells without trimming, and doubt 33s will fit. The thread covers CJs generally rather than the Scrambler specifically, but the CJ-8 shares the CJ-7's front end and springs. Saggy old springs and wheel backspacing can make even 31s tight.
Biggest Jeep CJ-8 Scrambler tire at every lift
| LIFT | BIGGEST TIRE | WHAT IT TAKES |
|---|---|---|
| Stock | 31x10.50R15 | The CJ owners' consensus for an unlifted CJ-7-bodied Jeep on 15x8 wheels; 32s only on tired springs |
| 2.5 in | 33x12.50R15 | Fits for mild use with the steering stops reset; expect contact when stuffed |
| 4 in | 33x12.50R15 | Comfortable trail setup for 33s; plan on regearing |
