Lift Height Reference Guide
| Lift | Max Tire | Notes |
|---|---|---|
| 0" | 32" | Stock height. Limited to OEM tire size or slightly larger. |
| 1" | 33" | Leveling kit. Allows ~1 inch larger tires. |
| 2" | 33.5" | Small lift. Good for 33" tires. May need minor trimming. |
| 2.5" | 34" | Popular lift height. Fits 33-34" tires comfortably. |
| 3" | 35" | Common lift. 35" tires fit most trucks. May need wheel spacers. |
| 3.5" | 35.5" | Allows 35" tires with better clearance. Fender trimming recommended. |
| 4" | 36" | Good for 35-36" tires. Fender trimming usually needed. |
| 5" | 37" | Allows 37" tires. Requires fender trimming and possibly wheel spacers. |
| 6" | 38" | Serious lift. 37-38" tires. Requires significant modifications. |
| 8" | 40" | Extreme lift. 40" tires possible with heavy modifications, regear required. |
How It Works
Enter your current tire size and select a lift height. The calculator uses lift-to-tire-clearance data to determine the maximum tire diameter your vehicle can accommodate.
It then generates a list of common off-road tire sizes (in popular widths from 265 to 315mm) that fit within that maximum diameter. Sizes are sorted largest-first so you can see the biggest options at a glance.
Note: actual fitment varies by vehicle make, model, wheel offset, and fender clearance. These results are general guidelines for full-size trucks and SUVs. Always verify with your specific platform.
How to Read a Tire Size
A tire size like P265/70R17 breaks down as:
- P — Passenger tire (LT = Light Truck)
- 265 — Section width in millimeters
- 70 — Aspect ratio (sidewall height is 70% of width)
- R — Radial construction
- 17 — Rim diameter in inches
Flotation sizes like 33x12.50R15 use inches: 33" overall diameter × 12.5" width on a 15" rim.
Frequently Asked Questions
What size tires can I fit with a 3-inch lift?
A 3-inch lift typically allows 35-inch tires on most trucks and SUVs. However, you may still need wheel spacers or minor fender trimming depending on your vehicle and wheel offset. Always check with your specific vehicle platform for clearance details.
Do I need to re-gear after installing bigger tires with a lift kit?
If you go up more than 2 inches in tire diameter, re-gearing is recommended to restore factory-like performance and fuel economy. For example, going from 32-inch to 35-inch tires on a truck with 3.73 gears would benefit from switching to 4.56 gears.
What is the difference between a leveling kit and a lift kit?
A leveling kit (1-2 inches) raises only the front of the vehicle to match the factory rear rake. It is simpler to install and less expensive. A lift kit raises the entire vehicle uniformly and usually includes new shocks, control arms, and other suspension components.
Will a lift kit void my warranty?
Under the Magnuson-Moss Warranty Act, a dealer must prove that the aftermarket part directly caused a failure to deny a warranty claim. A lift kit should not void unrelated powertrain warranty claims, but suspension-related claims may be affected. Check with your dealer before installation.
