1. What Is Uptis and What Advantages Does It Offer?
Frequently Asked Questions 1. What is Uptis and what advantages does it offer? Uptis (acronym standing for “Unique Puncture-proof Tire System”) is an assembled airless wheel structure. Uptis has been made possible through Michelin’s mastery and expertise with tire mechanics and high-tech materials. It also represents an evolution of Michelin’s expertise in TWEEL technology. Uptis can be thought of as the first in a new generation of airless solutions. This technology for passenger vehicles offers a number of advantages: ▪ Car drivers feel safer and more secure on the road due to the reduced risk of flat tires and other air loss failures that result from punctures or road hazards. ▪ Fleet owners and professional vehicle drivers optimize their business productivity (no downtime from flats, near-zero levels of maintenance). ▪ Raw material use is reduced, which in turn reduces waste. 2. Why do car drivers feel more at ease with Uptis? Uptis is designed to be impervious to traditional tire failures due to air loss. It does not use compressed air. It therefore eliminates the need for regular inflation pressure maintenance. 3. What is the strategy behind Uptis? Uptis represents Michelin’s vision for the future of mobility. Michelin illustrated its vision of sustainable mobility through the Vision concept1, which the Group unveiled at the Movin’On World Summit on Sustainable Mobility in 2017. Uptis shows how Michelin is adhering to its roadmap for research and development, which comprises these four main pillars of innovation: Airless, Connected, 3D-printed and 100% Sustainable (i.e., renewable or bio-sourced materials). -
Lowering Fleet Operating Costs Through Fuel
LOWERING FLEET OPERATING KEY TAKEAWAYS COSTS THROUGH FUEL EFFICIENT Taking rolling resistance, maintenance, TIRES AND RETREADS wheel position and tires, both new and WHAT YOU NEED TO KNOW TO RUN LEANER retread, into account allows companies to maximize fuel efficiency. Author: Josh Abell, PhD • Rolling resistance has a direct and significant correlation to the fuel A retreaded tire can be just as fuel efficient, economy of the vehicle. or even better, than a new tire. • Tires become more fuel efficient as they are worn due to lessened Rolling Resistance: Why it Matters rolling resistance. Rolling resistance is a measurement of the energy it takes to roll a tire on a surface. • Even among new and retread tires For truck tires, rolling resistance has a direct and significant correlation to the fuel claiming to be Smartway certified, economy of the vehicle. Whether you run a single truck or an entire fleet, tire rolling actual rolling resistance will vary. resistance is a crucial element that should be taken into account to minimize fuel costs. Since fuel costs are one of the biggest expenses in trucking operations, as tire rolling resistance decreases, your savings add up. Tire rolling resistance is measured in a lab using realistic and well-established test parameters relied upon by tire/vehicle manufacturers and government regulators. From this testing, original tires and retreaded tires can be quantified by a rolling resistance coefficient, known as “Crr.” The lower the Crr, the better. Studies have shown that a reduction in Crr can result in real-world fuel savings. For example, a 10% reduction in Crr for your truck tires can reduce your fuel consumption by 3%, and lead to savings of $1,000 or more per truck per year.1 © 2017 Bridgestone Americas Tire Operations, LLC. -

Mosbacher, ScK:retary NATIONAL INSrmJTE OF STANDARDS AND TECHNOLOGY John W. Lyons, Director ABSTRACT The use of seismic isolation bearings to decouple buildings and lifeline structures from strong ground motion has received an increased amount of attention in recent years. While several types of seismic isolation bearings have been developed and proposed for use, the most common type is the laminated rubber (elastomeric) bearing. Because the design lifetime of these bearings is expected to be on the order of 50 to 100 years, the long-term performance of the rubber must be addressed. Therefore, a literature review was conducted to identify potential limits on the long-term performance of rubbers used in bearings. Several issues, including the need for consensus performance standards and for additional research on the effects of creep, aging, temperature, and high-energy radiation on the properties of rubber, were identified. -
Exxon™ Butyl Rubber Innertube Technology Manual
Exxon™ butyl rubber Exxon™ butyl rubber innertube technology manual Country name(s) 2 - Exxon™ butyl rubber innertube technology manual Exxon™ butyl rubber innertube technology manual - 3 Abstract Many bias and radial tires have innertubes. Radial truck tube-type tires are particularly common, and in many instances, such as in severe service, off-road applications, are preferred over tubeless radial tire constructions. The technology requirements for tubes for such tires is, in many respects, equally demanding when compared to that for the tire and wheel in the assembly. This manual has been prepared to describe how butyl rubber is important in meeting the demanding performance requirements of tire innertubes. Representative innertube compound formulations and compound properties are discussed along with typical processing guidelines of the compound in the manufacture of innertubes. Chlorobutyl rubber based compound formulations are also used in innertubes. Such innertubes show good heat resistance, durability, allow greater flexibility in compounding, and process equally well as regular butyl rubber tube compounds. An extensive discussion of bicycle tire innertubes has been included. Service conditions can range from simple commuting and recreation to high speed competitive sporting applications. Like automobile and truck tire innertubes, tubes for bicycle tires can thus have demanding performance requirements. Guidelines on troubleshooting provide a checklist for the factory process engineer to enhance manufacturing efficiency, high -

Mechanics of Pneumatic Tires
CHAPTER 1 MECHANICS OF PNEUMATIC TIRES Aside from aerodynamic and gravitational forces, all other major forces and moments affecting the motion of a ground vehicle are applied through the running gear–ground contact. An understanding of the basic characteristics of the interaction between the running gear and the ground is, therefore, essential to the study of performance characteristics, ride quality, and handling behavior of ground vehicles. The running gear of a ground vehicle is generally required to fulfill the following functions: • to support the weight of the vehicle • to cushion the vehicle over surface irregularities • to provide sufficient traction for driving and braking • to provide adequate steering control and direction stability. Pneumatic tires can perform these functions effectively and efficiently; thus, they are universally used in road vehicles, and are also widely used in off-road vehicles. The study of the mechanics of pneumatic tires therefore is of fundamental importance to the understanding of the performance and char- acteristics of ground vehicles. Two basic types of problem in the mechanics of tires are of special interest to vehicle engineers. One is the mechanics of tires on hard surfaces, which is essential to the study of the characteristics of road vehicles. The other is the mechanics of tires on deformable surfaces (unprepared terrain), which is of prime importance to the study of off-road vehicle performance. 3 4 MECHANICS OF PNEUMATIC TIRES The mechanics of tires on hard surfaces is discussed in this chapter, whereas the behavior of tires over unprepared terrain will be discussed in Chapter 2. A pneumatic tire is a flexible structure of the shape of a toroid filled with compressed air. -

Information on Tire Radial Force Variation (RFV)
Information on Tire Radial Force Variation (RFV) 2019 and Prior GM Passenger Cars and Light Duty Trucks This Bulletin also applies to any of the above models that may be Export from North America vehicles. This Bulletin has been revised to add the 2018 and 2019 Model Year. Please discard Corporate Bulletin Number 00-03-10-006M. Important Before measuring tires on GM approved tire force variation measurement equipment, the vehicle MUST be driven a minimum of 24 km (15 mi) to ensure removal of any flat-spotting. Refer to the latest version of Corporate Bulletin Number 03-03-10-007: Tire/Wheel Characteristics of GM Original Equipment Tires. GM approved tire force variation measurement equipment MUST be calibrated prior to measuring tire/wheel assemblies for each vehicle. Note If the equipment being used is capable of performing a centering check, the centering check must be completed before taking measurements of balance or RFV. The purpose of this bulletin is to provide guidance to GM dealers when using GM approved tire force variation measurement equipment. This type of equipment can be a valuable tool in diagnosing vehicle ride concerns. The most common ride concern involving tire radial force variation is highway speed (105-115 km/h (65-70 mph) shake on smooth roads. Tire related smooth road highway speed shake can be caused by three conditions: imbalance, out of round and tire force variation. These three conditions are not necessarily related. All three conditions must be addressed. Imbalance is normally addressed first, because it is the simplest of the three to correct. -
