Characteristics including stopping distance on a wet road surface, maximum lateral acceleration on a wet road surface and noise-vibration-harshness (NVH) were evaluated on varying types of pavements typically encountered on public roadways.  \nU.S. sales data spanning a four-year period (2013 – 2016) was used to determine the most frequently purchased passenger car and light truck. As a result, the Toyota Camry and Ford F-150 were selected as test vehicles to represent their respective categories. For each vehicle, the most common original equipment (OE) tire size was tested.  \nResearch Questions:  \n1. Are there performance differences in certain scenarios between high-priced and low-priced tires?  \na. Quantitatively determined by analysis of wet stopping distances, wet maximum lateral acceleration and NVH characteristics.  \n2. Are there performance differences in certain scenarios between new tires and tires artificially worn to a tread depth of 4/32” in terms of:  \na. Wet stopping distance?  \nb. Wet maximum lateral acceleration?  \n3. What is the average cost difference between a new high-priced tire versus a new low-priced tire?  \nKey Findings:  \n1. On average, new high-priced tires did not perform significantly better than new low-priced tires in terms of stopping distance on a wet road surface, maximum lateral acceleration on a wet road surface and NVH characteristics.  \n2. Compared to new tires, tires worn to a tread depth of 4/32” exhibit:  \na. An increased stopping distance of 42 percent for the Toyota Camry and 44 percent for the Ford F-150. When decelerating from 60 mph, worn tires are still traveling at 39 mph and 37 mph at the average stopping point of new tires for the Toyota Camry and F-150, respectively.  \nb. A decreased maximum lateral acceleration on a wet road surface of 33 percent for the Toyota Camry and 28 percent for the Ford F-150.  \n3. A set of four higher priced tires cost, on average, $247.52 more for the Toyota Camry and $203.80 for the Ford F-150.  \n1 This research received no specific grant from any funding agency in the public, commercial or not-for-profit sectors.  \n2 The authors declare no conflicts of interest in preparing this article.  \nContents  \n1 Introduction .......................................................................................................................................... 6  \n2 Background ........................................................................................................................................... 6  \n2.1 Tire Types .................................................................................................................................................. 7  \n2.2 Tire Components ....................................................................................................................................... 7  \n2.3 Tire Specifications.................................................................................................................................... 10  \n2.4 Uniform Tire Quality Grade (UTQG) Standards ....................................................................................... 12  \n3 Vehicle Selection Methodology.......................................................................................................... 13  \n4 Tire Selection Methodology ............................................................................................................... 13  \n4.1 2017 Toyota Camry.................................................................................................................................. 14  \n4.2 2017 Ford F-150 .............................................................................................","cbCaiuCu4ytVPyao","https://ap.wps.com/l/cbCaiuCu4ytVPyao","pdf",5607953,65,"English","# Introduction\n# Background\n## Tire Types\n## Tire Components\n## Tire Specifications\n## Uniform Tire Quality Grade (UTQG) Standards\n# Vehicle Selection Methodology\n# Tire Selection Methodology\n## 2017 Toyota Camry\n## 2017 Ford F-150\n# Test Equipment and Resources\n## Vehicle Dynamics Equipment\n## NVH Equipment\n## Data Logging Equipment\n## Test Facility\n# Inquiry #1: Performance Differences by Tire Price","[{\"question\":\"What performance areas were evaluated in the study?\",\"answer\":\"The study evaluated wet-road stopping distance, maximum lateral acceleration on a wet surface, and NVH characteristics (noise-vibration-harshness).\"},{\"question\":\"Which vehicles and tire sizes were selected for testing?\",\"answer\":\"Toyota Camry and Ford F-150 were selected from U.S. sales data, and the most common original equipment (OE) tire size for each vehicle category was tested.\"},{\"question\":\"Do new high-priced tires outperform new low-priced tires in this research?\",\"answer\":\"On average, new high-priced tires did not significantly perform better than new low-priced tires for stopping distance on wet roads, maximum lateral acceleration on wet roads, or NVH.\"}]","Tire Study Report - Primary Research Findings | PDF",1789719091,164]
