Research for a Uniform Quality Grading System for Tires. II. Wheel Speed Capability Test

Abstract The wheel speed capability of a tire is defined by a test method which determines the speed at which the tire fails on a laboratory test wheel. Data is reported on over 100 different passenger car tires of all grades and types over a range of sizes. A scaling system is devised for this property. It is found that the system produces consistent results for tires of given manufacturer's nominal grade across the size range tested and for samples produced several months apart.

Wet Surface

Abstract In tests with bias ply, belted bias, and radial commercial passenger car tires it was found that the rate of wear does not change as the tires are worn. It was also shown in a test which there were dry and wet periods that the same tires wore at a faster rate in the wet than in the dry. This observation was reinforced when a comparison of two tests run with duplicate sets of tires in January and June on the same course gave greatly different results; the greater rate of wear occurring in January when the course was continuously wet. Finally an explanation for the observation that tires wear faster on wet pavements has been proposed. The tire is more deformed passing through the contact patch on a wet surface than on a dry. In addition, the water, acting as a lubricant, reduces resistance to motion between surfaces of the cut rubber or the surface of the cutting asperity and the rubber.

Abstract The National Traffic and Motor Vehicle Safety Act of 1966 requires the establishment of a uniform quality grading system. This paper discusses the needs for the system and the complexity of the problem. The system proposed here will depend on five properties; tread wear, traction, impact resistance, endurance, and wheel speed capability.

Breaking Energy

Abstract A test procedure designed to classify tires according to their average breaking energy has been applied to a sample of passenger car tires. Data are reported on 127 different tires of all grades and types over a range of sizes. A scaling system is devised and applied to the data. It is found that the system leads to conclusions similar to those derived from the original data.
