Breaking Down SmartWay
According to the U.S. Environmental Protection Agency (EPA), between 1990 and 2013 freight activity grew more than 50%, and it is projected to nearly double again by 2040. By 2050, global freight transport emissions of CO2 will surpass emissions from passenger vehicles. Here’s what you need to know about the EPA’s voluntary public-private program to combat these issues.
The Rise of the CUV
A crossover or crossover utility vehicle (CUV) is a vehicle built on a car platform that combines features of a sport utility vehicle (SUV) with features from a passenger car, to varying degrees. Crossovers use the unibody construction typical of passenger vehicles instead of the body-on-frame platform found in light trucks and the original SUVs. CUVs
Deciphering the Sidewall
There is a lot you can tell about a tire just by looking at it. Federal regulations require most of that information to be branded on the sidewall, though not all of the markings are included on every tire. Let’s take a look at the markings and their meanings. Size-Metric The first one or two
Run-Flat Tires
While run-flat tires are designed to allow a driver to safely continue driving after a puncture, they cannot be driven on indefinitely – the idea is to give the driver enough time get to a repair facility. Most manufacturers allow continued operation after a loss of some or all inflation pressure for up to 50
Winter Tire Innovations
Winter tires have been around since 1934, when Finnish tiremaker Nokian introduced them for trucks. Two years later, Nokian added sizes for passenger cars. This was during a time when there were still many horses and carts on the roads, and motor vehicles didn’t have today’s handling and braking capabilities. Tires that helped keep trucks
Eco-Friendly Tires
There aren’t many products with a worse environmental image than tires. Too many people have seen huge piles of scrap tires, or worse still, burning tires that defy attempts to extinguish them. It’s a problem that’s hard to ignore, and, not surprisingly, tire manufacturers today seem to be very sensitive to the issue. Tiremakers stress their commitment
UTQG Ratings Unfurled
Today’s tires have so much information imprinted on their sidewalls (and labels) that reading all of it is like sitting down with a book. Part of the verbiage is the Uniform Tire Quality Grade (UTQG) ratings for treadwear, traction and temperature. But what exactly do those numbers and letters mean, where do they come from,
Speed Ratings
Across the pond in Germany, portions of the famed Autobahn do not have speed limits, so high-speed driving is very much the norm. In spite of its tolerance of high speeds, the German government is also very safety conscious. In order to allow drivers to match the speed capability of the tires installed on their
Determining the Right PSI
More than a few of us have spent time looking for the placard with a vehicle’s tire pressure recommendations. And more than a few consumers have looked at their owner’s manual or that elusive placard and wondered why the pressures there are different from the maximum pressure on the tire’s sidewalls. How do the automobile
When is Road Force Balance Overkill?
Can road force balancing really make a difference? To answer the question of whether road force balancing is overkill, we should probably start by reviewing some basics. We balance tire/wheel assemblies primarily to eliminate, as much as possible, vibration. Vibration produces ride disturbances that are uncomfortable for the driver and passengers and may cause uneven
Qualify Your Customer
The Internet has changed our lives in many ways, and tire dealers have not been immune to its transformative power. More customers than ever research their tire purchases on the Web, joining the ranks of readers who for years have relied on Consumer Reports and a variety of car publications for tire guidance. What hasn’t
Tire Testing From A to Z
There are three principal reasons tire manufacturers test their products: Competitive Benchmarking – From material formulations to overall tire performance and on-vehicle testing, engineers want to get a firm grasp on what the competition offers prior to the development of their next new tire. Research and Development – To develop a new tire, manufacturers test
