How Often Flat Tires Happen

🛞
~200 million flat tires per year in the U.S. — one puncture roughly every 7 seconds

Flat tires are by far the most common tire failure mode in the United States. Industry estimates put U.S. flat-tire volume in the hundreds of millions per year, dwarfing the catastrophic-blowout category.

  • An estimated 220 million flat tires occur in the U.S. each year — roughly one puncture every 7 seconds.
  • The average U.S. driver experiences approximately 5 flat tires in their lifetime.
  • 41% of U.S. drivers reported experiencing a flat tire or blowout in the previous 12 months; an additional 29% found a slow leak or partial puncture.
  • In 2024, the rate of flat tires requiring a tow rose 6% year-over-year, driven largely by newer vehicles arriving without a spare.

Top Causes of Flat Tires

🔩
Nails are the #1 puncture cause — 32% of recent flat-tire incidents

Roadside debris, potholes, underinflation, and tire aging are the four dominant categories driving flat-tire incidence. The Hankook Tire Gauge Index — the most widely cited consumer survey on flat-tire causes — breaks the data down by primary culprit.

  • Nails are the primary cause of flat tires for 32% of drivers who experienced one in the previous year — the most-cited single puncture object.
  • 48% of drivers believe potholes or road debris are the main cause of tire blowouts, with 31% pointing to aging tires.
  • A tire underinflated by more than 25% is 3× more likely to be a critical pre-crash factor than a properly inflated tire.
  • Vehicles older than 10 years experience the highest rate of pre-crash tire problems — older tires accumulate both heat-aging and tread wear, both of which raise puncture risk.
  • Common non-nail puncture objects include screws, glass shards, sharp metal fragments, and broken plastic — debris that concentrates on shoulders and at intersections.

Roadside Assistance & Flat Tire Calls

🚗
AAA responded to 32+ million roadside calls in 2015 — flats are consistently a top-3 reason

Roadside-assistance networks like AAA and Agero handle tens of millions of service calls per year, and flat tires consistently rank in the top three reasons drivers call for help — alongside dead batteries and lockouts.

  • AAA rescued a record-breaking 32 million drivers in 2015. Flat tires were among the top three roadside-assistance reasons, alongside battery failures and lockouts.
  • In 2014, AAA responded to more than 29 million roadside calls; 17 million involved battery failures, flat tires, or lockouts combined.
  • AAA technicians could not change 21,000 flat tires in a single year because the vehicle's locking lug-nut key was missing — a niche but persistent service-call complication.
  • Flatbed tows are 3× more common for electric vehicles than for ICE vehicles — driven primarily by the absence of a spare tire on most EV models.
  • Over 85% of EV roadside events require a tow — significantly higher than ICE vehicles, where the technician often resolves the issue on-site.

Flat Tire Crash, Injury & Fatality Data

⚠️
78,392 crashes · 10,275 injuries · 414 deaths per year in the U.S. (NHTSA foundational study)

NHTSA's Tire-Related Factors in the Pre-Crash Phase study (DOT HS 811 617, 2012) remains the most-cited source on tire-related crash, injury, and fatality counts. More recent NHTSA tire-related fatality estimates and industry analyses round out the picture.

  • 78,392 crashes per year in the U.S. are caused by flat tires or blowouts.
  • 10,275 non-fatal injuries per year are attributed to tire-related crashes.
  • 414 fatalities per year are attributed to flat tires or blowouts in the foundational NHTSA pre-crash study.
  • 511 people died on U.S. roads in tire-related crashes in 2024 — the most recent NHTSA tire-related fatality estimate.
  • 9% of crashes involve a vehicle with pre-crash tire problems per the National Motor Vehicle Crash Causation Survey.
  • Industry analyses of NHTSA crash data estimate tire blowouts contribute to approximately 11,000 crashes annually, with 70%+ occurring above 50 mph.

The Disappearing Spare Tire

📉
30% of new vehicles ship without a spare — up from just 5% in 2006

The single biggest structural change in flat-tire response over the last 20 years is the disappearance of the full-size spare. CAFE fuel-economy standards and EV weight optimization have pushed automakers to ship vehicles with temporary spares, sealant kits, run-flat tires, or no spare at all.

  • Approximately 30% of new vehicles are sold without any spare tire, up from 5% in 2006 — a 6× increase over 15 years.
  • Approximately 65% of new vehicles ship with a temporary (donut / space-saver) spare. Full-size spares are now mostly limited to certain SUVs and pickups.
  • Eliminating a spare tire, jack, and tools removes roughly 30 pounds from the vehicle — a meaningful contribution to fuel-economy and range targets.
  • Most EVs ship without a spare tire to reduce overall weight and preserve battery range — a key reason 85%+ of EV flat tires require a tow.
  • Replacement options when a vehicle has no spare: a sealant + inflator kit, run-flat tires, or a call for roadside assistance and tow. Sealant kits fail on sidewall damage and on punctures larger than 1/4 inch.

Underinflation: The Hidden Flat-Tire Risk

💨
69% of vehicles have at least one underinflated tire — only 19% maintain proper pressure

Underinflation is the dominant precursor to flat tires, sidewall failure, and blowouts. Even after universal TPMS adoption in 2008, the majority of U.S. vehicles still run on at least one underinflated tire — a quiet but persistent flat-tire risk factor.

  • 69% of vehicles on the road have at least one underinflated tire, per a Rubber Manufacturers Association survey of 3,300 vehicles across 26 U.S. cities.
  • Only 19% of consumers properly inflate their tires, despite universal TPMS adoption since 2008.
  • Only 42% of drivers regularly check their tire pressure.
  • 12% of all U.S. passenger vehicles of model years 2004–2011 have at least one tire underinflated by 25% or more — the threshold at which TPMS triggers a warning.
  • Properly inflated tires save drivers as much as 11 cents per gallon on fuel; underinflation creates sidewall flexion that worsens rolling resistance and accelerates puncture failure.
⚡
EVs are 3× more likely than ICE vehicles to need a tow after a flat tire

Electric vehicles are reshaping flat-tire response because of three compounding factors: heavier curb weight, thinner range-optimized tread, and the near-universal absence of a spare. Agero's roadside data shows the result — EV flats are dramatically more likely to require a tow.

  • EVs are 3× more likely to require a tow in the event of a flat tire than comparable ICE vehicles.
  • Over 85% of EV roadside events necessitate a tow, often requiring specialized equipment to prevent damage to the battery pack.
  • EVs typically have 20–30% faster tire wear than ICE vehicles due to higher curb weight and instant torque, which raises baseline puncture exposure on worn tread.
  • The flat-tire tow rate rose 6% in 2024 versus 2023, with EVs identified as a major driver of the increase.
  • EV resolution times average 18% longer (~12 min) than ICE roadside events, and customer satisfaction (NPS) drops nearly 20 points on average when an EV roadside event is poorly handled.

Driver Behavior & Preparedness

🛠️
65% of U.S. drivers feel confident changing a tire — up from 52% in 2015

Driver self-sufficiency on flat-tire response has improved over the last decade, even as more vehicles ship without spares. Hankook's annual Gauge Index survey tracks the trend year over year.

  • 65% of U.S. drivers now feel confident changing a tire themselves, up from 52% in 2015 — a meaningful improvement in roadside-emergency self-sufficiency.
  • 28% of drivers who recently had a flat tire changed it themselves; 24% called roadside assistance.
  • Among Gen Z drivers who experienced a flat, 45% were more likely to call roadside assistance than to change the tire themselves; Millennials were most likely to do it themselves at 37%.
  • 50% of drivers say they are not familiar with run-flat tires — a knowledge gap that limits adoption of an alternative to the disappearing spare.
  • 45% of Americans report relying more on professionals for basic maintenance due to increased vehicle technology, including tire pressure and tread checks.

Prevention & TPMS Statistics

🛡️
TPMS cuts severe underinflation 55.6% — but only 19% of drivers still inflate properly

Federal regulators mandated TPMS on all new U.S. passenger vehicles starting with model year 2008 under FMVSS 138. The technology has measurably reduced severe underinflation — but driver behavior remains the dominant barrier to eliminating flats from underinflation.

  • All passenger vehicles sold in the U.S. since September 2008 are required to include TPMS under FMVSS 138.
  • TPMS effectiveness studies show a 55.6% reduction in severe underinflation (≥25%) for equipped vehicles versus comparable unequipped vehicles.
  • FMVSS 138 requires TPMS to warn the driver when one or more tires fall to 25% or more below recommended pressure — the threshold where crash risk rises 3×.
  • NHTSA TireWise recommends drivers check tire pressure monthly, inspect tread depth monthly, rotate tires every 5,000–8,000 miles, and verify alignment annually.
  • Despite universal TPMS deployment since 2008, only 19% of consumers still properly inflate their tires — the warning light alone is insufficient to change driver behavior.

Frequently Asked Questions

How often does the average driver get a flat tire?
The average U.S. driver experiences approximately 5 flat tires in their lifetime, per the Hankook Tire Gauge Index. In any given 12-month period, 41% of U.S. drivers experience a flat tire or blowout, and another 29% find a slow leak or puncture they did not realize until later.
How many flat tires happen each year in the U.S.?
Industry estimates put U.S. annual flat tire volume at roughly 200–220 million per year — about one tire puncture every 7 seconds. The figure includes both roadside flats and at-home discoveries (e.g., a tire found low when leaving for work).
What is the #1 cause of a flat tire?
Nails are the most-cited primary puncture object — 32% of drivers who experienced a flat in the last year identified a nail as the cause, per the Hankook Tire Gauge Index. Other top causes include screws, glass, road debris from potholes, and slow leaks from valve-stem or bead failures.
How many crashes per year are caused by flat tires?
Approximately 78,392 crashes per year in the U.S. are caused by flat tires or blowouts, resulting in an estimated 10,275 injuries and 414 fatalities annually, according to NHTSA's pre-crash factors study (DOT HS 811 617). The figure has declined modestly over the past 15 years as TPMS deployment and tire-quality standards have improved.
Why don't new cars come with a spare tire?
Approximately 30% of new vehicles are sold without any spare tire — up from just 5% in 2006. The trend is driven by federal fuel-economy standards (CAFE), EV weight reduction targets, and cargo-space optimization. A typical spare tire, jack, and tools add about 30 pounds. Replacement options include sealant kits, run-flat tires, and roadside assistance.
Are EVs more prone to flat tires than gas cars?
EVs are not necessarily more prone to flats, but they are far more likely to need a tow when one occurs. EVs are 3× more likely than ICE vehicles to require a tow after a flat tire, per Agero's 2024 roadside data, because most EVs ship without a spare to preserve range. Combined with 20–30% faster tire wear and higher curb weight, EVs also see elevated puncture exposure on worn tread.
What percentage of vehicles drive on underinflated tires?
Approximately 69% of vehicles have at least one underinflated tire, per a Rubber Manufacturers Association survey of 3,300 vehicles in 26 U.S. cities. Only 19% of drivers maintain proper inflation across all four tires, and only 42% regularly check pressure. Underinflation is the single most common precursor to a flat — a tire underinflated by 25%+ is 3× more likely to be a critical pre-crash factor.
How effective is TPMS at preventing flat tires?
TPMS is highly effective at preventing severe underinflation but does not eliminate the flat-tire problem because most drivers ignore early warnings. NHTSA's TPMS effectiveness study found a 55.6% reduction in severe underinflation in equipped vehicles. However, only 19% of drivers properly inflate their tires even with TPMS, indicating behavioral change is the remaining barrier.
