Tire blowout or tread separation on the 2004 Jayco Designer
Only 2 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When tire blowout or tread separation gets reported
There are 2 reports of tire blowout or tread separation on the 2004 Jayco Designer, 2 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 38,000 miles. It is the 1st most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 1,900 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, every year of the Jayco Designer
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.
Tl*the contact owns a 2004 jayco designer fifth wheel travel trailer. The vehicle has goodyear marathon tires. The contact stated that the tread separated and blew out the sidewall while driving 65 MPH. She heard a loud boom and noticed that the rear passenger side tire had blown; however, the stability of the vehicle did not change. The failure and current mileages were less than 2,000.
Dt: the consumer stated the valve stems ruptured. The consumer caught some of the tires before they blew out. The faulty valve stems caused the tires to go flat. There are only 2,800 miles on the tires on this 2004 jayco 5th wheel designer trailer. The consumer has contacted jayco through his dealer. Jayco said they contacted the stem manufacturer and it was normal wear and tear of the tire, and jayco can not do anything about it. This is the first incident with these tires and it was a total of 6 wheels on all locations, four tires went at once. The owner just so happened to be pulling in to a campground when he noticed a problem. The consumer heard the air leaking out from the tires. The consumer then contacted road assistance for help, but has not driven on the tires since returning home. The consumer does plan on replacing these with steel valve stems. *nm
How far this goes
This page is kept out of search results because 2 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 2 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 2004 Jayco Designer?
Across 2 owner reports that included an odometer reading, half were filed by 1,900 miles. A quarter were filed before — and a quarter after —. 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 2004 Jayco Designer?
2 reports have been filed with NHTSA, about 6.4 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.
