The certification label may list an incorrect gross front axle weight rating and/or incorrect tire pressures. As such, these vehicles fail to comply with the requirements of 49 CFR Part 567, "Certification."
Risk: If the tire pressure is understated, an underinflated tire may result in an increased risk of tire failure, increasing the risk of a crash.
