Happy New Year - 2022!

You probably know tires are made of rubber — but how much more do you know? Here’s a run-through of some important tire-related terminology:
1) Aspect ratio
This technical-sounding term refers to the relationship between the width of a tire and the height of the tire’s sidewall. High-performance “low profile” tires have “low aspect ratios” — meaning their sidewalls are short relative to their width. This provides extra stiffness and thus better high-speed handling and grip — but also tends to result in a firmer (and sometimes, harsh) ride. “Taller” tires tend to provide a smoother ride and better traction in snow.
2) Contact Patch
As your tires rotate, only a portion of the total tread is actually in contact with the ground at any given moment. This is known as the contact patch. Think of it as your tire’s “footprint.” Sport/performance-type tires are characterized by their wider footprint — more tread is in contact with the ground — which provides extra grip, especially during hard acceleration on dry pavement and during high-speed cornering.
3) Treadwear indicators
These are narrow bands built into the tread during manufacturing that begin to show when only 1/16 of the tire’s tread remains. Also called wear bars, treadwear indicators are there to provide an obvious visual warning that it’s time to shop for new tires.
4) Speed ratings
An alpha-numeric symbol you’ll find on your tire’s sidewall that tells you the maximum sustained speed the tire is capable of safely handling. An H-rated tire, for example, is built to be safe for continuous operation at speeds up to 130 mph. Most current model year family-type cars have S (112 mph) or T (118 mph) speed ratings. High performance cars often have tires with a V (149 mph) or ZR (in excess of 149 mph) speed rating. A few ultra-performance cars have W (168 mph) and even Y (186 mph) speed-rated tires.
5) Maximum cold inflation load limit
This refers to the maximum load that can be carried in a given vehicle with a given type of tires — and the maximum air pressure needed to support that load. In your vehicle’s owner’s manual, you should be able to find the recommended cold inflation load limit. It’s important not to exceed the load limit (or over or under-inflate the tires) as this can lead to stability/handling problems and even tire failure. Always check tire pressure “cold.” Driving creates friction which creates heat; as the tires warm up, the air inside expands, increasing the pressure. Measuring air pressure after driving can give a false reading; you may actually be driving around on under-inflated tires.
6) Load index
This number corresponds to the load carrying capacity of the tire. The higher the number, the higher the load it can safely handle. As an example, a tire with a load index of 89 can safely handle 1,279 pounds — while a tire with a load rating of 100 can safely handle as much as 1,764 pounds. It’s important to stick with tires that have at least the same load rating as the tires that came originally with the vehicle — especially if it’s a truck used to haul heavy loads or pull a trailer. It’s ok to go with a tire that has a higher load rating than the original tires; just be careful to avoid tires with a lower load rating than specified for your vehicle, even if they are less expensive. Saving a few bucks on tires is not worth risking an accident caused by tire failure.
7) Radial vs. bias-ply tire
Bias-ply tires have their underlying plies laid at alternate angles less than 90 degrees to the centerline of the tread; radials have their plies laid at 90 degrees to the centerline of the tread. That’s the technical difference. The reason radial tires are dominant today is that they help improve fuel efficiency and handling; they also tend to dissipate heat better than bias-ply tires. No modern passenger cars come with bias-ply tires these days and their use is generally not recommended. (Exceptions might include older/antique vehicles that originally came equipped with bias-ply tires. Some RVs also used bias-ply tires, etc.) It is very important never to mix radial and bias-ply tires; dangerously erratic handling may result.
8) LT and MS tires
These designations indicate “Light Truck” and “Mud/Snow” — and are commonly found on tires fitted to SUVs and pick-ups. LT-rated tires are more general purpose, built primarily for on-road use — while MS-rated tires typically have more aggressive “knobby” tread patterns designed for better off-road traction.
9) Temporary Use Only
Many modern cars come with so-called “space-saver” tires which are smaller and lighter than a standard or full-size spare tire. They are designed to leave more room in the trunk and be easier for the average person to handle when a roadside tire change becomes necessary. However, they are not designed to be used for extended (or high-speed) driving. Your car will probably not handle (or stop) as well while the Space Saver tire is on – and you should keep your speed under 55 mph and avoid driving on the tire beyond what’s absolutely necessary to find a tire repair shop where you can have your damaged tire repaired or replaced.
10) Treadwear, Traction and Temperature ratings
Each tire has three separate ratings for Treadwear, Traction and Temperature.
Traction ratings run from AA to A to B and C — with C being the lowest on the scale. The ratings represent the tire’s ability to stop on wet pavement under controlled testing conducted by the government. C-rated tires are marginal and should be avoided. Never buy a tire with a Traction rating that isn’t at least equal to the minimum rating specified by the manufacturer of your vehicle.
Temperature ratings from A to B to C — with C being the minimum allowable for any passenger car tire. The ratings correspond to a given tire’s ability to dissipate heat under load; tires with lower ratings are more prone to heat-induced failure, especially if driven at high speeds (or when overloaded). As with Traction ratings, never buy a tire with a Temperature rating that’s less than specified for your vehicle.
Treadwear ratings differ from Traction and Temperature ratings in that they aren’t a measure of a tire’s built-in safety margin. Instead, these ratings — represented by a three digit number — give you an idea of the expected useful life of the tire according to government testing. A tire with a Treadwear rating of 150, for example, can be expected to last about 1.5 times as long as a tire with a Treadwear rating of 100. These are just guides, however. Your tires may last longer (or not) depending on such factors as how you drive, whether you maintain proper inflation pressure and rotate the tires per recommendations — and so on.

DEARBORN, Mich., March 8, 2021 – Every trip a driver makes can reveal important digital clues to fleet operators about how their vehicles are being used, unlocking insights to improve employee performance and vehicle health. Now, Ford is ensuring no vehicle gets left behind by expanding Ford Telematics to support all makes and models – regardless of automaker.
This new capability alongside new tools offered by Ford Telematics1 gives businesses the flexibility they need to manage their fleets, while helping to better manage driver behavior, performance and compliance goals.
“At Ford, our commitment to fleet customers goes beyond the mix of their fleet,” said Alex Purdy, Director of Business Operations, Enterprise Connectivity, Ford Motor Company . “By supporting all makes and models, expanding the capabilities of Ford Telematics and providing complimentary management tools, we’re arming fleet managers with the knowledge they need to maintain uptime and increase productivity across their fleet.”
With Ford Telematics, fleet operators can now gather, view and monitor data from all their vehicles, regardless of manufacturer. With this expanded functionality, fleet managers will be able to analyze all of their fleet vehicles in one easy to use dashboard– including the ability to improve uptime, monitor performance and plan maintenance services.
Customers can leverage this capability on most non-Ford vehicles by using a plug-in device that connects to each vehicle with a wiring harness that leaves the OBD II port available for use. Additionally, this expanded functionality is provided as part of the regular subscription cost for Ford Telematics.
The ability to support all makes and models is just the latest step Ford has taken to expand the breadth of Ford Telematics. Fleet customers who deploy electric vehicles also have access to an electric vehicle telematics dashboard, which provides features such as electric-vehicle data, charging reports, and web-based pre-conditioning that can help optimize battery efficiency.
Managing behavior and compliance
Ford Telematics is designed to help customers improve the management and performance of their fleets. The service is constantly introducing new features to do just that, including a fleet-wide driver behavior dashboard and individual driver scores that help improve performance.
The driver behavior dashboard gives managers a survey of how their vehicles are performing, providing information about trends that involve harsh braking or acceleration, speeds driven over posted limits and/or fleet-set thresholds, seatbelt use and idling time. A personal driver score also lets fleet managers quickly see how specific drivers are doing, giving them opportunities to further coach them on best practices and areas of improvement.
“Because there’s so much data at our fingertips, it’s critical to give fleet managers a clear and simple way to gain insight into their business,” said Purdy. “Ford Telematics gives managers an easy way to break down performance trip by trip, driver by driver, so they can focus on running a safe, productive fleet.”
Severe incident notifications, meanwhile, let fleet operators know when their drivers and vehicles have been involved in a severe incident where the airbag has been triggered. E-mail and in-app alerts can relay the driver involved, the location of the crash and the time. Vehicle misuse notifications enable managers to set operating hours and receive notifications if their vehicles are being used inappropriately during off-hours.
Improving uptime
Information is the lifeblood of any organization, and commercial fleets are no exception. That’s why Ford is moving to make its services even more accessible with the launch of Ford Telematics Essentials2 for Ford vehicles, a complimentary level of service for commercial customers that will be available beginning in the second quarter of 2021.
Ford Telematics Essentials gives customers access to vehicle health insights such as odometer readings, diagnostic trouble code and information around oil life, engine hours and recalls. Later this year, this complimentary service will also allow fleets to digitally track and plan maintenance or repair services with local dealers.
Meanwhile, Ford Telematics continues to expand its feature offerings and the amount of data it can share with fleets about their vehicles, with support for more than 3,800 diagnostic trouble codes. These codes help identify potential issues with vehicles, and are coupled with alerts that tell customers whether they should take action immediately or soon in order to remedy a situation.
Further bolstering Ford’s mission to improve uptime for commercial fleets is the widespread adoption of over-the-air update capability, beginning with the 2021 F-150. Vehicles equipped with this technology can receive updates and repairs wirelessly, reducing the need to visit a dealer for maintenance. These updates can be delivered in the background or scheduled by the driver at their convenience, creating another way to keep fleets up-to-date and on the road.

• Ford user experience team uncovered important customer wants with cardboard prototype made in a few hours with scissors, a razor blade and a hot glue gun
• Mega Power Frunk design and engineering teams faced lofty challenges, including an asymmetrical frunk, drainable floor and waterfall hood design to meet customer expectations
DEARBORN, Mich.– A cardboard box found a new lease on life after being recruited by Ford to help develop a new feature known as the Mega Power Frunk. The all-electric 2022 F-150 Lightning pickup’s new front trunk or, as it’s known in industry speak “frunk” is the largest in the truck industry – with 400 liters (14.1 cubic feet) of cargo space and maximum payload capacity of 400 pound
“The F-150 Lightning pickup’s Mega Power Frunk is one of those features that reshape what vehicles can provide for customers. It’s sheer size, ample power supply, drainable floor and open and close system that opens with the touch of a button make it frunking awesome!” said Linda Zhang, F-150 Lightning Chief Program Engineer.
What many don’t know is this spacious and dynamic space began life as a simple cardboard box with a cutout front door and a liftable hood.
Understanding the Customer’s Needs
It began back in February 2018 with Team Edison – Ford’s dedicated battery electric vehicles incubator that incorporates close collaboration between different teams to find solutions to customer needs. A small group of young user experience designers set out to California, where they sat down with actual Ford truck and fleet customers to talk about how they might use such a feature. The prototype, made of cardboard for simplicity and cost and built in about a day using scissors and hot glue, was brought to every meeting to help customers visualize the opportunity.
In the studio, Greg Ardisana, design strategy director, passenger vehicles, and other Team Edison research members worked as consultants alongside engineering and design whenever they had customer use questions, which led to a close-knit collaboration between groups.
Once the frunk is open, customers can fill it with ice and drinks to “frunkgate” it, since it’s water-resistant, cleanable and has a drainable floor.
Steve McInally, frunk feature supervisor, said the team explored every detail as an opportunity. “We put the customer first in every decision we made and were able to deliver on a Mega Power Frunk,” he said. “And it’s going to blow people’s minds.” The 2022 F-150 Lightning pickup will be available starting Spring 2022.
