* Stock tire size: The stock tire size on a 1995 Ford Explorer varied depending on the trim level and options. You'll need to know your Explorer's original tire size to determine the potential for interference.
* Wheel well clearance: 31-inch tires are significantly larger than the stock size. They might rub against the fenders, suspension components, or bodywork, especially during turning or when the suspension compresses.
* Gear ratio: Larger tires effectively change the gear ratio of your vehicle. This will affect acceleration, fuel economy, and speedometer accuracy. You might need to adjust the gear ratio (with a re-gearing of your differentials) or use a speedometer calibrator to compensate for the change.
* Rubbing: Even with sufficient wheel well clearance, rubbing can occur on other parts of the vehicle's body or chassis, particularly during articulation (like going over bumps).
* Suspension lift: To avoid rubbing, you'll likely need a suspension lift kit. The amount of lift required will depend on the specific 31-inch tire size and wheel offset. A body lift is an alternative but less ideal solution.
In short: While it *might* be possible to fit 31-inch tires with significant modifications (lift kit, possibly trimming, and potentially a speedometer recalibration), it's not a straightforward bolt-on upgrade. You should thoroughly research the specific tire size you're considering and consult with a 4x4 shop experienced with modifications on Ford Explorers of that era to assess feasibility and required modifications. Attempting this without proper preparation could lead to damage to your vehicle.
