How much does a 12R22.5 tire weigh?
2 Answers
12R22.5 multi-ply special tires can exceed 100KG. Definition of PR: PR stands for ply rating, which refers to the nominal number of cord layers in the tire rubber. It does not completely match the actual number of cord layers but serves as an important indicator of tire strength. The ply rating is marked in Chinese, such as 12-ply, or in English, such as "14P.R" meaning 14-ply. Common truck tires: Truck tires generally come in the following sizes: 12.00-20-18PR, 12.00R20-18PR, 10.00-20-18PR, 10.00R20-18PR.
I've driven trucks for half my life and am very familiar with 12r22.5 tires. These things weigh around 65 to 75 kilograms each, which is quite heavy. When I drive long distances, I can clearly feel that heavier tires slow down acceleration, and even when the truck is empty, they consume more fuel, costing several hundred yuan more per trip. When changing tires, I often advise fellow drivers not to just look at the price but to choose the right brand and tread pattern. For example, Michelin or Bridgestone's medium-weight models, around 65 kilograms, provide better stability on highways. On heavy rainy days, slightly heavier tires offer better grip, but they make starting slower, so you have to balance safety factors. Some in my fleet switched to tires over 70 kilograms, only to struggle with climbing hills. Later, switching to lighter ones made things much easier and also extended the chassis's lifespan. In short, when choosing tires, test them out more—don't just rely on specs, as the actual driving experience can vary greatly.
