Lift Kit Tire Clearance Calculator

With a 3-inch lift, you can typically increase your tire diameter by 2-3 inches over stock. This varies by vehicle type and wheel well clearance, but most trucks and SUVs can accommodate 33-35 inch tires with proper wheel offset.

Wheel offset is the distance from the wheel's hub mounting surface to its centerline. Negative offset pushes wheels outward, providing better clearance for larger tires but may cause rubbing. Positive offset pulls wheels inward, which can limit tire size options on lifted vehicles.

Not always, but it's often recommended. Your current wheels may work with slightly larger tires, but for maximum tire size, wheels with appropriate width and offset will provide better fitment and performance.

Yes, larger tires will cause your speedometer to read slower than actual speed. A 3-inch diameter increase typically results in about 8-10% speedometer error. Many vehicles can be recalibrated or use aftermarket modules to correct this.

4WD vehicles typically have more front-end components like CV axles, differential, and transfer case that can limit tire clearance. 2WD vehicles often have more room in the front wheel wells for larger tires with the same lift height.

Limited size increases are possible without a lift, typically 1-2 inches in diameter. However, this may cause rubbing during turning or suspension compression. A proper lift kit ensures adequate clearance for larger tires.

Wider wheels allow for wider tires and can improve the tire's footprint. However, too wide can cause interference with suspension components. Most lift applications work well with wheels 8-10 inches wide.

Off-road driving requires additional clearance for suspension articulation and tire flex. Consider at least 1-2 inches extra clearance beyond static measurements, especially around fender wells and suspension components.
