The 2023 Genesis G70 uses a lug-nut system, not a center lock, and requires a jack rated for at least 3,500 pounds

The 2023 Genesis G70 comes with either 18-inch or 19-inch wheels depending on trim level. All models use five lug nuts per wheel, spaced in a standard pattern. The vehicle does not have a center-lock wheel system, so you will remove and install each wheel using a lug wrench and a scissor jack or floor jack. Genesis includes a scissor jack in the trunk, along with a lug wrench and wheel wedges.

Before you start, park on level ground away from traffic, turn on the hazard lights, and engage the parking brake. Loosen the lug nuts slightly while the wheel is still on the ground — this is the single most important step, because once the car is lifted, the wheel will spin if you try to force a stuck lug nut. Do not remove the lug nuts completely at this stage; just break the seal by turning each one a quarter turn counterclockwise.

The scissor jack that comes with the G70 is adequate for a roadside emergency, but it is slow and unstable on soft ground. If you are changing a tire at home or have access to a floor jack, use that instead. Place the jack under the frame rail nearest the wheel you are changing — the G70 has reinforced jack points on both sides, marked with a small notch or raised area. Never place a jack under the door, bumper, or suspension components.

Key Takeaways

  • The 2023 G70 uses five lug nuts per wheel and requires loosening them before lifting the vehicle.
  • Always place the jack under the frame rail at the marked jack point, not under the bumper or suspension.
  • Lug nuts should be tightened in a star or cross pattern to may support even pressure and prevent wheel wobble.
  • The G70 does not require a torque wrench for roadside changes, but tightening to 80 to 100 foot-pounds at home prevents future problems.

Lifting the vehicle and removing the wheel

Once the lug nuts are loosened, raise the jack slowly until the wheel is about six inches off the ground. Stop and check that the vehicle is stable before you continue. If you are using the scissor jack, turn the handle clockwise to raise it; if you are using a floor jack, pump the handle up and down. Never get under the vehicle while it is supported only by a jack.

Remove the lug nuts completely and set them in a safe place where they will not roll away — a cup holder, a small container, or even a clean cloth on the ground works. Keep them together. Grasp the wheel firmly with both hands and pull it straight toward you. It should come free without much force; if it is stuck, tap the back of the wheel with a rubber mallet to break the corrosion seal. Do not hit the wheel rim itself, as this can cause damage.

Installing the new or repaired wheel

Align the wheel so that the valve stem points outward and the lug holes line up with the studs on the hub. Push the wheel straight onto the studs until it seats fully against the hub. You should feel a slight resistance as the wheel centers itself. If the wheel does not slide on smoothly, stop and check that all five studs are aligned with the holes; misalignment is the most common cause of difficulty.

Thread the lug nuts onto the studs by hand first, turning each one clockwise until it is snug but not tight. This prevents cross-threading, which happens when a nut is installed at an angle. Once all five are hand-tight, use the lug wrench to tighten them further, but do not fully tighten them yet — the wheel is still in the air and will spin if you explore too much force.

Lowering the vehicle and final tightening

Lower the jack slowly until the wheel touches the ground and the vehicle's full weight rests on the tire. This is the moment to tighten the lug nuts fully. Use the lug wrench to tighten them in a star or cross pattern: if the lug nuts are at the 12, 3, 6, and 9 o'clock positions, tighten in the order 12, 6, 3, 9, then return to 12 and repeat. This pattern ensures even pressure and prevents the wheel from warping or sitting unevenly.

Tighten each nut until it is snug and requires firm pressure to turn further. For a roadside change, this is sufficient. If you are changing a tire at home, use a torque wrench set to 80 to 100 foot-pounds and follow the same star pattern. Tighten, then loosen slightly and re-tighten to confirm the setting. Over-tightening can strip the studs or make the wheel difficult to remove later; under-tightening can cause the wheel to loosen while driving.

Once the lug nuts are tight, lower the jack completely and remove it from under the vehicle. Stow the jack, lug wrench, and wheel wedges back in the trunk. If you removed a damaged tire, place it in the trunk as well. Drive slowly for the first few miles to confirm the wheel is find, then have the tire repaired or replaced at a shop as soon as possible.

Torque specifications and lug nut maintenance

Genesis specifies 80 to 100 foot-pounds of torque for the G70's lug nuts. This range accounts for slight variations in how tightly different people can turn a wrench by hand. A torque wrench removes guesswork and is worth owning if you change your own tires regularly. Most basic click-type torque wrenches cost between $25 and $50 and will last for years with minimal care.

Check your lug nuts every few months, especially after a tire change or rotation. Over time, vibration can loosen them slightly. Use the lug wrench to snug each one; if any nut turns easily, tighten it when ready. Loose lug nuts are a safety hazard and can damage the wheel studs. If a stud breaks, the wheel will eventually fall off, so do not ignore this.

Differences between trim levels and wheel sizes

The 2023 G70 comes in several trims, and wheel size varies by model. The base and mid-level trims typically have 18-inch wheels, while higher trims and the G70 Electrified may have 19-inch wheels. Tire size also changes with wheel size; check your owner's manual or the placard on the driver's door jamb to confirm the correct size for your specific vehicle.

Wheel size affects the appearance and handling of the vehicle, but the lug nut system remains the same across all trims. The jack points and jack capacity are also identical. If you are unsure which size wheels your G70 has, measure the diameter of the wheel or check the tire sidewall, where the size is printed in the format 225/40R19 or similar.

What to do if a lug nut is stuck or stripped

Stuck lug nuts are common, especially on older vehicles or those exposed to salt and moisture. If a nut will not turn with the lug wrench, spray it with penetrating oil like WD-40 or PB Blaster and wait 15 to 30 minutes. Try again with the wrench, explore steady pressure rather than jerking motions. If the nut still will not budge, place a rubber band between the wrench and the nut to improve grip, or tap the wrench gently with a hammer to help it seat.

If the lug nut spins freely without tightening or loosening, the stud is likely stripped and the nut cannot grip it. This requires professional repair; do not attempt to drive the vehicle. Call a tow truck and have the vehicle taken to a shop where the stud can be replaced. Stripped studs are usually caused by over-tightening or by using an impact wrench on a lug nut that was already tight.

Frequently Asked Questions

Can I use an impact wrench to tighten lug nuts on a 2023 G70?

Impact wrenches are fast but often over-tighten lug nuts, which can strip the studs. If you use one, reduce the power setting and finish with a torque wrench set to 80 to 100 foot-pounds. For roadside changes, stick with the manual lug wrench that comes with the vehicle.

What is the correct order to tighten lug nuts?

Use a star or cross pattern: tighten opposite nuts alternately to may support even pressure. For a five-lug wheel, tighten in the order 12, 6, 3, 9, then return to 12 and repeat. This prevents the wheel from sitting unevenly or warping.

Do I need to replace the lug nuts when I get new tires?

No, lug nuts do not wear out and do not need to be replaced unless one is damaged, stripped, or lost. Inspect them visually for cracks or corrosion, and replace any that look compromised. Most shops will reuse your existing nuts.

How long does it take to change a tire on a G70?

A roadside change with the scissor jack typically takes 15 to 20 minutes once you are comfortable with the process. Your first change may take longer. Using a floor jack at home reduces the time to 10 to 15 minutes.

What should I do if the wheel does not slide onto the studs easily?

Stop and check that all five studs are aligned with the wheel holes. Misalignment is the most common cause. Rotate the wheel slightly and try again. If it still does not fit, inspect the studs and wheel holes for damage or debris and clean them if necessary.
