Expertise

I have over 30 years experience in the design, manufacturing, and testing of tires. I have served as the technical advisor to the "800" number. I have authored or co-authored many publications - usually without credit. I can answer almost any technical question, but please don`t ask me to compare brands. I probably have prejudices because of my work experience.

Experience in the area

Member SAE (Society of Automotive Engineers) Member Tire Society (Tire Technical Organization) SCCA Regional Competiton License holder Authored many training manuals on tires, their care and use.

Organizations

SAE (Society of Automotive Engineers) SCCA (Sports Car Club of America) Tire Society

Education/Credentials

I am a graduate of the University of Dayton, Dayton, OH - BME, 1971 I attended graduate school at the University of Akron - but did not complete my PhD - something I regret.

What do you still hope to achieve/learn in this field?

I want to dispell many of the "myths" about tires so people will be better informed.

Something interesting about this subject that others may not know:

Tires are a highly engineered product that face some of the most severe environments - the road.

Something controversial or provocative about this subject

The vast majority of tire failures are caused by road hazards and lack of proper tire maintenance, not manufacturing defects.

2016-09-18 tire pressure:

Skip,    You asked:    1. How is it that cold pressure can vary but hot pressure always levels out at the "correct" driving pressure and stays there while driving? That just seems to defy logic!
