30 kg/hour: ‘Inciner’s’ new benchmark – ‘inciner’s’ 30 kg/hour rule of thumb’s up

Inciner’s New Benchmark Benchmark

The 30 kg/hour rule of thumb is a prominent benchmark used in the US to assess the performance of b-grade and industrial-grade (IG) tires. This rule, which is widely used throughout the world, helps manufacturers to determine the quality and performance of tires.

How the 30 kg/hour benchmark works

The 30 kg/hour rule is a performance indicator used to assess the design and quality of tires. It is based on two main criteria:

• Load-to-mass (L/M) rating – reflects the tire’s load-to-mass characteristics.
• CircumCircumCircumstance (C/L) – refers to the ratio of tread depth to overall tire diameter.

**The 30 kg/hour rule states that a tire must not be loaded to more than 30 kg (approximately 133.4 kg) or have a 30mm (1.8in) tread depth/diameter ratio.

The 30 kg/hour rule’s main criteria are:

• **The weight of the tire must not be less than 30 kg/hour in the size of 2.55mm/16in (about 30mm/19mm) – 30mm, 30mm to 35mm – 30mm
• The tread depth must be 35mm (1.8in) or more – 30mm/35mm

**The 30 kg/hour rule provides a level of quality standard that has been widely accepted by the tire industry – a 30 kg/hour tire would not meet the minimum quality requirement of a 35mm/35mm tire.

The 30 kg/hour rule is often used in the following areas to ensure that tires meet quality and performance standards and that they can be appropriately manufactured and used in consumer applications

The 30 kg/hour rule is in place

• In passenger cars and pickup trucks
• Truck tires and light/semi-truck tires
• High-performance sport tires

Additional notes

• The 30 kg/hour rule is just a starting point. As a tire’s size and quality increase, additional criteria such as speed, tread depth and sidewall construction are used to improve quality and performance.
• The 30 kg/hour rule should not be used as the sole criteria for tire qualification.
• A 30 kg/hour tire would not meet the quality and performance of a 35mm/35mm tire.

Here are some of the tire industry’s guidelines related to 30 kg/hour rule

• In 2005, the United States Department of Justice set a 30kg/hour rule to qualify tires as “good practice” and to ensure high-quality tires.
• In 2007, the Asian/Pacific Tire and Automakers Association (ATRA) and the European Tire Manufacturers’s Association (ETMA) set a 30 kg/hour rule as a guideline to assess the quality and performance of tires.

**The 30 kg/hour rule provides a level of quality standard that has been widely used and accepted by tire producers and consumers alike. By setting a 30 kg/hour benchmark on tires, we can set a quality standard that not only meets the minimum (30 kg/hour) but also allows us to assess and ensure quality and performance of tires of all types and sizes.

The 30 kg/hour rule has been a highly useful and practical benchmark used to assess and ensure tire quality and performance. In addition to the 30 kg/hour benchmark, other criteria such as speed, tread depth, and sidewall construction must be met to ensure tire quality and performance.

The 30 kg/hour rule has been widely accepted by tire manufacturers and consumer groups to ensure that both passenger cars and commercial and heavy-duty tires meet quality and performance standards.
