Why Does It Matter?
Treadwear Programs – Tire designers are challenged to develop new tread patterns that deliver longer tread life and more uniform tread wear. Starrett-Bytewise partnered with Ford Motor Company and several leading OEM tire makers to develop CTWIST in order to measure and characterize tread wear so that all tire makers could qualify their tread wear behavior with a uniform standard. With the CTWIST process, new tires are scanned after break-in, then periodically scanned during the wear cycles. CTWIST predicts the tread life for each rib and produces several tread wear reports to help the designer understand where improvements are needed.
Tire360 can run our CTWIST Software for tread wear analysis with a considerable savings in test time. This time savings calculation compares Tire360 to fixed point scanning methods for a high-volume test center:
- 50 vehicles every 10 days = 20 tires scanned per day.
- Tire360 scan time only is only a few seconds for complete tire including sidewalls.
- Fixed point scan is about 15 minutes per scan = 5 hours per day.
- Scan time saving is about 5 hours per day = 1734 hours (72 days) per annum.
- This will dramatically change your work-flow.
- This will give you 72 more days of driver time per year otherwise spent waiting for testing to be done.
Production Tire Testing - Tire makers routinely measure production tires to verify the geometric precision. This is traditionally done with various hand tools and is time consuming. Tire360 incorporates many of the test operations into an automatic test routine. These include measurements for section width, circumference, tread radius, wheel runout, plus the location and height of treadwear indicators and corresponding tread depth. Tire360 greatly simplifies the work-flow and reduces the time for many tire testing processes.
Tire Development Testing – Tire manufacturers dedicate substantial effort in finite element modeling tires in order to design molds that produce tires that inflate to the intended design size and shape. Powerful computers with highly specialized software applications are used to predict the size and shape of the tire after inflation. Once the first tire is molded it is measured to see how close the “as-built” tire complies to the “as-designed” tire. Differences can be analyzed to improve the design process.
Current practices for measuring the size and shape of developmental tires, in many cases, is done by laying the tire on a granite table in a metrology lab, marking measurement points by hand, and manually measuring each point. Tire360 reduces the time required to measure a new tire from hours to minutes.
Competitive Analysis - Tire manufacturing is a fiercely competitive business; and tire makers routinely buy competitors’ tires in order to analyze materials, construction, dynamic properties, treadwear, styling, size and shape, and tread design. Tire360 makes it easy to scan any tire and view 2D cross-sectional profiles with key dimensional measurements.
