Can you drive on 10 PSI?

Yes, you can drive on 10 PSI tires for a short distance, but it is not recommended. Driving on significantly underinflated tires can lead to blowouts, uneven tire wear, reduced gas mileage, and poor handling.

What Does 10 PSI Mean for Your Tires?

10 PSI (pounds per square inch) is extremely low tire pressure. Most passenger vehicle tires have a recommended pressure between 30-35 PSI. Here’s what 10 PSI means for your tires:

  • Tires will be severely underinflated, appearing very flat
  • The tire sidewalls will flex significantly more than normal when driving
  • The tire tread will not make full contact with the road, reducing traction
  • The center of the tread will wear faster than the edges due to distortion
  • Rolling resistance increases, reducing gas mileage
  • Tires will overheat more easily, increasing the chances of a blowout
  • Handling, cornering, braking distances, and control will be negatively impacted

In most cases, you should not drive a vehicle if any of the tires are at 10 PSI or lower. The only exception would be driving very slowly and carefully to the nearest service station to reinflate your tires.

Is It Safe to Drive on 10 PSI?

Driving on 10 PSI tires is not safe, but there are a few factors that determine just how unsafe it is:

  • Speed – The faster you drive, the more dangerous it becomes. At low speeds under 30 mph, it may be possible to slowly drive a very short distance.
  • Distance – The further you drive on severely underinflated tires, the higher the risk. Only drive if reaching a service station is less than a few miles away.
  • Tire Type – Performance tires with stiff sidewalls may be slightly safer than tires with more flexible sidewalls when severely underinflated.
  • Tire Size – Smaller tire sizes found on compact cars are generally safer than larger tire sizes on trucks and SUVs if significantly underinflated.
  • Load – The more weight in the vehicle, the more strain on the underinflated tires.

While it’s never recommended, driving slowly and for very short distances of a mile or less can reduce the safety risks if absolutely necessary. But the handling and braking deficits at 10 PSI mean you need to be extremely cautious.

Key Dangers of Driving on 10 PSI

Here are some of the biggest dangers of driving a vehicle when your tires are at just 10 PSI pressure:

  • Blowouts – Extremely underinflated tires can overheat and experience sidewall flexing/distortion leading to sudden air loss and blowouts.
  • Loss of Control – Poor braking distances, traction, steering responsiveness, and stability management drastically increase the chances of accidents.
  • Uneven Wear – Underinflated tires wear unevenly and rapidly, potentially leading to early tire failure.
  • Damage to Wheels – Hitting potholes or road hazards is more likely to bend, crack, or break wheels due to insufficient cushioning from 10 PSI tires.

Driving on tires that are underinflated by 20+ PSI should only be done in true emergencies where no other option exists. Motorists should have their vehicle towed or transported on a flatbed to avoid these serious risks if possible.

What to Do If You Have a Tire at 10 PSI

If you check your tire pressures and find that one or more is at just 10 PSI, here are the recommended steps to take:

  1. Turn on your vehicle’s hazard lights and safely pull over and park if driving.
  2. Check the visual condition of the underinflated tires. Look for any damage, punctures, or sidewall bulges.
  3. Carefully drive below 30 mph to the nearest service station, tire shop, or safe location to inflate tires if less than a mile away. Otherwise, call for roadside assistance.
  4. At the station, use an accurate pressure gauge to check the actual PSI if tires appear very underinflated.
  5. Reinflate your tires to the vehicle’s recommended inflation pressure, usually around 30-35 PSI.
  6. Have the tire inspected for damage if it was driven while extremely underinflated.
  7. Determine the cause of the air loss if a leak is found. Repair as needed.

A tire pressure monitoring system can alert you to an underinflation situation before it becomes an emergency. Maintaining proper inflation will also minimize the chances of a tire reaching 10 PSI while driving.

Is It OK to Drive on a Temp Spare at 10 PSI?

No, you should not drive on a temp spare tire that is underinflated to 10 PSI. Temp spares or “donut” tires have limitations and are only intended for short-term emergency use:

  • Temp spares typically have a maximum pressure rating of around 50 PSI.
  • They have reduced load weight capacities compared to full-size tires.
  • Temp spares can be difficult to properly reinflate without special compressors.
  • The small size impacts handling and braking if operated while severely underinflated.

Most temp spares perform best between 60-70 PSI inflation pressure. You should avoid driving on them at less than 20 PSI if possible. Only drive cautiously on a temp spare if reinflating it is not an option.

Can Driving on 10 PSI Damage Your Car?

Yes, driving on tires with only 10 PSI inflation can lead to multiple types of damage to your vehicle. Some potential consequences include:

  • Premature tire wear and damage
  • Uneven tire treadwear
  • Wheel and rim damage from hitting potholes
  • Reduced fuel economy and gas mileage
  • Strain on suspension components
  • Engine, transmission, and drivetrain stress
  • Body and structural damage from loss of control

The low inflation causes the tires to distort, which can lead to overheating and sudden failure. It also reduces their ability to cushion the vehicle from impacts. Even short drives on severely underinflated tires boosts the chances of costly damage.

Tire Damage

Driving on underinflated tires typically leads to faster center tread wear along with damage from the excessive sidewall flexing under loads. The tread depth will become uneven across the width of the tire, shortening its overall life.

In extreme cases, cracks, bubbles, or bulges can form in the sidewalls. Portions of the tread could even separate. Hitting road hazards is also more likely to cause punctures, cuts, or tears in the tire body when operating at very low pressures.

Wheel Damage

Wheels and rims are more prone to damage when driving on 10 PSI tires. The lack of sufficient air cushioning means that impacts from potholes, curbs, debris, and other road hazards transfer more force through the tire to bend, dent, or crack the wheel.

In bad cases, an underinflated tire striking a pothole or object can bend, warp, or even crack lightweight alloy wheels. Striking bumps and curbs when parking also becomes more damaging without enough tire pressure to absorb the impact.

Improving Fuel Economy with Proper Inflation

Maintaining the vehicle manufacturer’s recommended tire pressure has significant benefits for improving your fuel economy and gas mileage. Here’s how proper inflation can reduce fuel costs:

  • Minimizes tire rolling resistance, reducing drag and friction
  • Prevents tires from distorting, decreasing heat buildup and flexing
  • Allows tread to run flat on road surface for better contact
  • Reduces weight of vehicle via less fuel load needed
  • Enables optimal transmission shifting and performance

Studies have shown underinflated tires by 6-8 PSI can increase fuel consumption by up to 2%. Check your pressures at least monthly to optimize inflation levels.

Tire Pressure Monitoring Systems

Modern TPMS units can automatically alert drivers when tire pressures drop 25% below recommended levels. This provides an early warning to address underinflation before it reaches dangerous levels around 10 PSI.

Monitoring each tire’s pressure allows motorists to maintain the optimal inflation needed for safety, handling, and fuel efficiency. The small sensors mounted in each wheel pay major dividends in extending tire life and preventing blowouts.

Tips for Maintaining Proper Tire Pressure

Here are some tips for ensuring your tires remain properly inflated rather than reaching dangerously low pressures of 10 PSI:

  • Check inflation levels at least monthly using an accurate pressure gauge.
  • Examine tires for punctures, damage, and uneven wear during inflation checks.
  • Have a reputable shop address any slow leaks or tire damage promptly.
  • Rotate tires every 5,000-8,000 miles to promote even treadwear.
  • Purchase quality tires built for durability, handling, and performance.
  • Align wheels and adjust suspension components as needed.
  • Load vehicle and tires according to manufacturer GVWR specifications.

Maintaining proper tire pressures goes a long way in preventing emergency situations like running on 10 PSI. Being vigilant and proactive with maintenance fosters driving safety.

What to Do After Driving on 10 PSI

If you had no choice but to drive on a tire or tires with only 10 PSI inflation, be sure to take the following steps once reinflated:

  1. Inspect tires closely for any damage like cuts, cracks, bulges, or punctures.
  2. Check wheels and rims for new dents, warping, or cracks.
  3. Test drive the vehicle at low speeds to check for vibration or pulling.
  4. Examine inner and outer tire tread and sidewalls for uneven or rapid wear.
  5. Rotate tires to promote even wear after driving on underinflation.
  6. Schedule a wheel alignment if pulling, imbalance, or uneven wear are detected.
  7. Continue monitoring inflation levels frequently to avoid reoccurrence.

The excessive flexing from extreme underinflation can cause hidden damage or alignment issues. Being cautious and observant following an incident will help restore safety and extend the service life of your tires.

Key Takeaways

  • Only drive a very short distance under 30 mph if a tire is at 10 PSI until reaching a filling station.
  • Severely underinflated tires risk blowouts, uneven wear, loss of control, and damage to wheels.
  • Proper inflation between 30-35 PSI is crucial for safety, fuel economy, handling, and extending tire life.
  • Regularly check pressures and have any punctures, leaks, or damage repaired promptly.
  • Use TPMS to get alerts when inflation drops 25% below recommended levels.

While it’s possible to cautiously drive a very short distance on a tire with just 10 PSI, it is an extremely dangerous practice that should be avoided. Maintaining optimal inflation will keep your vehicle running safely and efficiently.
