What are the standards for replacing tires on in-yard vehicles?

Automotive tire replacement standards include tread deformation or carcass pattern detachment, tire bulging, and tread punctures exceeding 6mm. Tread deformation or carcass pattern detachment: This is a relatively severe tire issue. Since the tire carcass pattern has already detached, it should be replaced immediately for both aesthetic and safety reasons. Tire bulging: Tire bulging mainly occurs on the tire sidewall, primarily due to the tire violently hitting curbs, large rocks, speed bumps, etc., causing the tire cord layer to rupture. If a tire bulge persists for a long time, combined with high-temperature exposure and high-speed driving, it can easily lead to a tire blowout, which is extremely dangerous. Tread punctures exceeding 6mm: Small punctures on the tread can actually be repaired, but if the puncture exceeds 6mm, repairing becomes meaningless because the gap is too large. Even if repaired, there's no guarantee the tire won't fail again. Therefore, it's best to replace tires with punctures larger than 6mm. Tire sidewall exposing the cord layer: Exposure of the cord layer on the sidewall may result from scraping against hard objects while driving or from wheel rim pressure. Along with the exposed cord layer, there is usually significant cord breakage, so the tire should be replaced immediately.
As someone who frequently works in the garage repairing cars, I've seen plenty of tire issues. The standards for replacing tires on in-house vehicles mainly depend on a few key points: tread depth must be maintained at least 1.6mm or more, which can be checked using a coin or tread depth gauge; below this value, tires are especially prone to skidding and causing accidents in rainy conditions. You also need to check for cracks or bulges, which are signs of aging. Generally, tires should be replaced after five or six years of use, regardless of wear. Additionally, if there's uneven wear, a wheel alignment adjustment is necessary to prevent the vehicle from pulling to one side. I recommend checking tire pressure and tread condition quarterly—don't wait until a blowout happens to act. Road safety comes first, and regular tire replacement can prevent problems before they occur.
