# When to Replace Tires on Most Vehicles

Replace tires every **4 to 6 years** or after **40,000 to 60,000 miles** on typical cars. This keeps you safe and saves money on repairs. Most drivers hit this range with normal use.

## Key Signs It's Time for New Tires
Watch for these clear signals:
- **Tread depth below 2/32 inch**: Use the penny test. Put a penny in the tread with Lincoln's head down. If you see the top of his head, replace now.
- **Age over 6 years**: Tires crack with time, even with low miles. Check the DOT code on the sidewall for the manufacture date.
- **Cracks, bulges, or uneven wear**: These mean danger. Stop driving and get them checked.
- **Vibration or poor handling**: Your car feels off. Tires cause most steering issues.

| Sign | What to Check | Action |
|---|---|---|
| Tread | Penny test: 2/32 inch min | Replace if less |
| Age | DOT code: week/year | Swap after 6 years |
| Damage | Sidewall cracks/bulges | Inspect right away |
| Wear | Uneven pattern | Rotate and align |

According to AAA's 2025 Driving Costs study, tires make up 8% of yearly ownership costs, or about $925 on average for a new car driven 15,000 miles per year (Source: AAA Your Driving Costs, 2025). "Proper tire maintenance cuts replacement needs by 20%," says the Sidekick Research Team, based on analysis of 1,200 verified owner records.

## Mileage and Driving Factors
Most tires last **40,000 to 60,000 miles**. Aggressive drivers or rough roads cut this to 30,000 miles. Smooth highways stretch it to 70,000. Track your miles with an app.

In zip code 70112, hot weather speeds tire wear. Heat in New Orleans ages rubber faster. Check tires every 3 months here.

## Steps to Check and Replace
1. Measure tread monthly. Use a gauge for accuracy.
2. Rotate tires every 5,000 to 8,000 miles. This evens wear.
3. Keep pressure at 32-35 PSI. Low air wears edges fast.
4. Align wheels yearly. Fixes pulling issues.
5. Buy quality tires. They last longer and grip better.

New tires cost $500 to $800 for a set on typical cars. Shop sales and match your driving. All-season tires suit most needs.
