First, this web site is very poorly identified. The data appears to be extracted directly from the NHTSA website, but it isn't identified as such.
It also doesn't do any analysis. You can't tell how many of what there is.
If you go and read some of the write ups, it's clear it isn't tires that is being talked about. Sometimes its the TPMS, or the vehicle. And some of the entries obvious aren't about a failure.
The part of the equation that is missing is the amount of production. Everything else being equal, tires with high production levels should appear more often than tires with low levels of production - and not to criticize, but it seems like the Goodyear Marathon is one of those very high production tires and you would expect them to appear quite frequently .
