Understanding what causes tire blowouts — and how to prevent them — is essential for every driver. In this guide, we’ll break down the most common causes, warning signs, and safety tips, plus what to do if it happens on the road in Nashville.
Common Causes of Tire Blowouts
1. Underinflation
One of the most common causes of a blowout is driving on underinflated tires. When tire pressure is too low, the sidewalls flex more than they should, generating heat and weakening the structure. This stress builds up over time until the tire fails — often suddenly.
Tip: Check your tire pressure at least once a month and before long trips. Use a reliable tire gauge and follow the manufacturer’s PSI recommendation, found on the driver’s side door frame or your vehicle manual.
2. Overloading the Vehicle
Every vehicle has a weight limit. When you exceed that limit — especially in hot weather or on long drives — it adds extra pressure on the tires, increasing the chances of a blowout.
Tip: Always check your vehicle’s load capacity before hauling heavy items. Never assume your tires can handle more than they’re rated for.
3. Potholes and Road Hazards
Sharp debris, potholes, curbs, and road construction zones are common culprits in tire blowouts. The damage may not be visible at first, but a weakened tire can rupture suddenly under pressure.
Tip: Try to avoid potholes when safe to do so. If you hit one hard, check your tire immediately. Any bulge or visible damage means you need a replacement — not a repair.
4. Old or Worn-Out Tires
Driving on worn or expired tires is a ticking time bomb. Old tires lose elasticity, and their tread depth becomes too shallow to safely grip the road, making blowouts more likely — especially during hot weather or at high speeds.
Tip: Replace tires every 6 years regardless of tread, and sooner if they show visible wear. Use the penny test or look for tread wear indicators to evaluate tire health.
5. Heat and Friction
Tires heat up while you drive, especially on hot Tennessee roads in the summer. If your tires are already under stress from poor maintenance or age, this heat can trigger a blowout.
Tip: Avoid high speeds on extremely hot days, especially if your tires are nearing the end of their lifespan.
Warning Signs Before a Blowout
In some cases, your car will give you hints that a blowout is imminent. Watch for:
- Vibration or thumping while driving
- Unusual pulling to one side
- A tire pressure warning light on your dashboard
- Cracks, bulges, or objects embedded in the tire
If you notice any of these signs, stop immediately and inspect the tire. It’s better to be safe than stranded.
What to Do If a Blowout Happens
If you experience a tire blowout while driving:
- Don’t panic. Grip the steering wheel firmly.
- Avoid slamming the brakes. Let the vehicle slow down naturally.
- Gradually steer to the side of the road.
- Turn on your hazard lights.
- Call for professional roadside help.

Preventive Maintenance Is Key

- Check tire pressure monthly
- Rotate your tires every 5,000 to 7,000 miles
- Inspect for visible damage or irregular wear
- Replace old or worn tires on time
- Get professional tire service before road trips
By staying proactive, you can greatly reduce your chances of experiencing a blowout.
