Tire blowout or tread separation on the 2007 Chevrolet Impala
When tire blowout or tread separation gets reported
Owners of the 2007 Chevrolet Impala report tire blowout or tread separation at a median of 45,000 miles. A quarter of the reports come in before 25,000 miles and a quarter after 70,000 miles, from 11 reports that carried an odometer reading.
A part like this is normally expected to survive 38,000 miles. It is the 21st most-reported problem on this model year.
The mileage distribution
The reported range runs from 25,000 miles at the tenth percentile to 90,000 miles at the ninetieth, a spread of 67,042 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
36% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 23,109 miles | 27,000 miles | 43,000 miles | 71,953 miles | 90,151 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $200–$1,500 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure on other years
The same failure is reported on 3 model years of this car. It shows up earliest on the 2008, at a median of 40,000 miles, and latest on the 2006 at 180,000 miles.
By volume the 2007 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
Vibration and pulling on highway in speeds above 60mph. Had tires rotated/balanced and numerous alignments performed without resolution. Third party inspected tires and found "tread separation" on 3 of the 4 tires. Tires exhibited these problems since about 29000 miles and were replaced at 36000. *tr
I am having excessive wear on the inside of both rear tires. I have replaced my rear tires twice in less than 5 months. Both of my rear tires blew out at the same time on 2/24/10 while I was driving on the highway. There has been a recall on the police vehicles for the same issue which turns out to be alignment issues. I am fearful for my safety in this car along with the expenses being incurred due to a poor quality product. *tr

How far this goes
Complaints are voluntary, so 12 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does tire blowout or tread separation happen on the 2007 Chevrolet Impala?
Across 11 owner reports that included an odometer reading, half were filed by 45,000 miles. A quarter were filed before 25,000 miles and a quarter after 70,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is tire blowout or tread separation on the 2007 Chevrolet Impala?
12 reports have been filed with NHTSA, about 0.2 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
