How to Change a Flat Tire Safely: A DIY Guide for Upland, CA Drivers

A flat tire can happen to anyone. Learn the safe, step-by-step way to get back on the road — plus what to pack and when to call a professional.

A flat tire can happen to anyone — a nail in the road, a pothole on Foothill Blvd, or just old rubber giving out on the 210 freeway. Knowing how to change a tire safely is one of the most useful skills any Upland driver can have. This guide walks you through it step by step.

What You'll Need

Keep these items in your vehicle at all times:

  • A spare tire (check its pressure monthly)
  • A jack and lug wrench (both should come with your vehicle)
  • Wheel wedges or heavy rocks
  • A flashlight and gloves
  • A flat piece of wood to stabilize the jack on soft ground
Step-by-Step

Changing Your Flat Tire

1

Find a Safe Spot

Never change a tire on a hill or on a narrow road. Pull over to a flat, level surface as far from traffic as possible. On busy Upland roads like Foothill Blvd, find a parking lot or a wide shoulder. Turn on your hazard lights.

2

Secure the Vehicle

Apply the parking brake. Place wheel wedges or rocks in front of and behind the tires on the opposite side of the flat to prevent the car from rolling.

3

Loosen the Lug Nuts

Use the lug wrench to loosen the lug nuts about a half turn each. Do not remove them yet — just break them loose while the wheel is still on the ground.

4

Jack Up the Vehicle

Place the jack under the reinforced jacking point near the flat tire. Refer to your owner's manual for the exact location. Raise the car until the flat tire is about six inches off the ground. If the ground is soft, place a flat piece of wood under the jack for stability.

5

Remove the Flat Tire

Now fully remove the loosened lug nuts and set them in a safe place. Pull the flat tire straight toward you to slide it off the wheel studs. Lay it flat on the ground so it doesn't roll away.

6

Mount the Spare Tire

Lift the spare tire and align the holes with the wheel studs. Push the tire all the way onto the studs. Hand-tighten the lug nuts in a star pattern — tighten one, then the one across from it, alternating until all are snug.

7

Lower the Car and Finish Tightening

Lower the jack until the tire touches the ground but the car's weight isn't fully on it yet. Give the lug nuts a final tighten with the wrench in the star pattern. Then lower the car fully and remove the jack. Give each lug nut one last check.

When to Call a Professional

If you don't have a spare, the spare is also flat, or you're on a dangerous road with no safe place to pull over, call for help. A damaged wheel, stripped lug nuts, or a jack that won't hold are all reasons to leave it to the pros. The team at 123 Auto Center can repair or replace your tire, inspect the wheel, and make sure you're safe to drive.

  • Spare tires are rated for 50 miles at speeds under 50 mph — get to a shop promptly

  • Inland Empire heat degrades rubber faster — inspect your spare at least twice a year
  • If your spare is a "donut" spare, avoid highway speeds on the 210
