You’re cruising down the highway in your 2023 Genesis G70—smooth ride, quiet cabin—when the steering suddenly feels off. Maybe the car starts pulling, or you hear that unmistakable thump-thump-thump. You pull over, step out, and there it is: a flat tire. Not exactly how you planned to spend your afternoon.
If you’ve never dealt with a tire change on a 2023 Genesis G70, you’re not alone. This isn’t an old beater with a full-size spare and a basic jack. The G70 is a modern luxury sport sedan, and that comes with specific procedures, tools, and safety considerations. Do it wrong, and you risk damaging the car—or worse, putting yourself in danger on the side of the road.
This guide walks you through everything you need to know, whether you’re stuck on a shoulder during rush hour or planning ahead in your garage. No fluff, no scare tactics—just real-world advice from experience.
Problem Explanation
Why Tire Changes Are Different on a 2023 Genesis G70
Changing a tire on a 2023 Genesis G70 isn’t complicated, but it is different from older cars. Many G70 trims come with run-flat tires or a tire mobility kit instead of a spare. Jack points are specific, and improper lifting can damage the underbody or side skirts.
On top of that, the low-profile tires and sport suspension mean less margin for error. One wrong move can bend a wheel, strip a lug, or trigger TPMS warnings that don’t reset easily.
Understanding these differences upfront makes the process smoother—and safer.
Common Causes
Why You Might Need a Tire Change
Most tire issues on a G70 come down to everyday road hazards. Here are the usual culprits:
- Nails or screws picked up from construction zones or parking lots
- Pothole impacts, especially after winter freeze-thaw cycles
- Sidewall damage from curbs or tight city parking
- Underinflation, causing excessive heat and internal failure
- Worn tread, making tires more vulnerable to punctures
Even with premium tires, no vehicle is immune—especially on rough US roads.
Symptoms / Warning Signs
How do you know it’s Time to change the tire?
Pay attention to these warning signs before things get worse:
- Sudden steering pull or vibration
- TPMS warning light on the dashboard
- Visible tire bulge, tear, or puncture
- Loud flapping or thumping noise
- Rapid loss of air pressure
If you notice any of these, slow down safely and pull over as soon as possible.
Step-by-Step Fixes / Solutions
How to Perform a Tire Change on a 2023 Genesis G70
1. Get to a Safe Location
Pull over to a flat, stable surface away from traffic. Turn on hazard lights and engage the parking brake. If you’re on a highway, prioritize safety over convenience.
2. Check What You’re Working With
Open the trunk and lift the floor panel. Depending on trim, you’ll find:
- A tire mobility kit, or
- A temporary spare tire (donut)
Know what you have before proceeding.
3. Locate Proper Jack Points
The G70 has clearly marked jack points along the rocker panels. Never lift from unmarked areas—this can crush pinch welds or damage body panels.
4. Loosen Lug Nuts First
Before lifting the car, slightly loosen the lug nuts using the factory wrench. Don’t remove them yet.
5. Jack Up the Vehicle
Position the jack correctly and raise the car until the tire is fully off the ground. Keep hands and feet clear.
6. Remove the Tire
Fully remove lug nuts, pull the tire straight off, and set it flat on the ground nearby.
7. Install Spare or Repaired Tire
Align the wheel, hand-thread lug nuts, then snug them in a star pattern.
8. Lower and Torque
Lower the vehicle and tighten lug nuts firmly. If possible, use a torque wrench later (Genesis recommends ~80–90 lb-ft).
9. Reset TPMS (If Needed)
Drive for a few miles or follow the reset procedure in the owner’s manual.
DIY vs Professional Repair
Should You Change the Tire Yourself?
DIY makes sense if:
- You’re comfortable lifting the car
- Conditions are safe and well-lit
- You’re using a spare or mobility kit
Call a professional if:
- You’re on a busy highway shoulder
- Sidewall damage is visible
- The wheel or suspension may be damaged
Luxury cars like the G70 aren’t forgiving when shortcuts are taken.
Safety Considerations
Don’t Put Yourself at Risk
- Always use hazard lights and reflective triangles if available
- Never crawl under a car supported only by a jack
- Avoid changing tires on soft shoulders or slopes
- Keep passengers away from traffic
No tire is worth risking your life.
Cost Expectations
What a Tire Change Might Cost
- DIY: $0–$30 (if you already have tools)
- Roadside assistance: $75–$150
- New tire replacement: $250–$400 per tire (performance sizes)
Prices vary by state, tire brand, and wheel size.
Prevention Tips
Avoid Future Tire Problems
- Check tire pressure monthly
- Avoid potholes and curb impacts
- Rotate tires every 5,000–7,500 miles
- Replace tires before tread gets too low
Preventive care saves money—and stress.
Common Mistakes
What G70 Owners Often Get Wrong
- Jacking from the wrong location
- Over-tightening lug nuts
- Driving too fast on a temporary spare
- Ignoring TPMS warnings afterward
These mistakes can lead to bigger repair bills.
Conclusion / Final Advice
Changing a tire on a 2023 Genesis G70 isn’t hard—but it demands attention and care. Know your equipment, follow proper steps, and don’t rush. When in doubt, roadside assistance is money well spent. A calm, informed approach keeps both you and your G70 in great shape.
