Do you need a lift kit for 20 inch rims?
In most cases you do not need a lift kit just to run 20-inch rims. If the overall tire diameter remains close to stock and there’s no rubbing, stock height is fine. If you plan larger tires or notice clearance problems, you may require leveling, spacers, or a lift.
Beyond that basic question, fitment depends on tire size, wheel offset, vehicle design, and local regulations. This article explains when a lift helps, what to check before upgrading, and how to proceed safely.
Key factors that influence the need for a lift
Key factors to assess before deciding on height adjustments when using 20-inch rims include tire diameter, wheel offset, and fender clearance, among others. Use this checklist to gauge whether a lift, leveling, or spacers might be necessary.
- Overall tire diameter vs. stock: A larger diameter increases the likelihood of rubbing in wheel wells, especially during suspension compression or steering.
- Wheel offset and width: Wheels with low or negative offset push the tire outward, which can contact fender lips, control arms, or brake components.
- Fender clearance and rubbing: Full suspension travel at full steering lock can cause contact with fenders, trim, or bumpers if clearance is insufficient.
- Vehicle type and factory suspension: Trucks and SUVs with tall suspensions may tolerate larger wheels differently than sedans, crossovers, or sport cars.
- Brake caliper and rotor clearance: Some 20-inch wheels require enough inner clearance to avoid caliper interference or rotor heating concerns.
- Speedometer and drivetrain effects: Bigger tires can alter gearing and odometer readings, sometimes requiring recalibration.
- Warranty, insurance, and legality: Local laws and manufacturer warranties can be affected by ride-height changes or wheel modifications.
Bottom line: if your 20-inch wheels and tires keep the overall diameter near stock, you can avoid a lift; otherwise, plan for a leveling kit, spacers, or a full lift to prevent rubbing, maintain alignment, and preserve safe handling.
Practical scenarios by vehicle type
Light-duty trucks and SUVs
Many pickups and SUVs can accommodate 20-inch rims without a lift if tire diameter remains close to stock and offset is appropriate. When you increase tire diameter beyond a small margin, a leveling kit or modest lift can help maintain clearance and ride quality. Always verify brake clearance and consider potential trimming or mud flaps to protect the bodywork.
Cars and crossovers
For sedans and crossovers, 20-inch rims are common with low-profile tires and often do not require a lift unless larger-than-stock tires are chosen. Focus on maintaining proper offset and ensuring sufficient wheel-well clearance to avoid rubbing at full suspension travel or during turns.
What to do if you’re unsure
Recommended steps include checking manufacturer fitment guides for your specific model, measuring current tire diameter, calculating the projected diameter with the new tires, physically testing a dry run with full steering lock, and consulting a tire-wheel or automotive professional for precise guidance.
Summary
Running 20-inch rims does not automatically require a lift kit. The key is matching tire diameter and wheel offset to your vehicle’s suspension and fender clearance. If you stay close to stock height and maintain adequate clearance, you can proceed without additional lift. If you plan a larger tire package or encounter rubbing, consider leveling, spacers, or a lift, and factor in brake clearance, alignment, and local regulations. Always seek professional fitment advice for your specific vehicle.
Can I put 20 inch rims on my truck?
Selecting 20-inch wheels for your truck will greatly improve both its look and performance. Larger wheels help to improve handling by lowering the sidewall height of tires, hence reducing their flex.
What are the disadvantages of 20 inch rims?
17-inch wheels are smaller in diameter and lighter. Therefore, they decrease braking distance and acceleration and are fuel efficient. On the other hand, the larger diameter of 20-inch results in slower acceleration, worse fuel efficiency, and better braking performance.
Can I lift my truck without a lift kit?
Safely? You don't. You could try and use something like spring spacers in the front but those will make your truck ride wrong and not drive straight, but if you lift it more than around an inch for most with stock shocks you're going to damage said stock shocks.
What size tire will fit a 20 inch rim?
35 Inch Tires For 20 Inch Rims
Or opt for a rough-and-tumble 35 inch all-terrain tire that behaves well on paved surfaces. No matter what, you'll get a mean stance and relentless traction when you upsize.
