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.
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.
I want to dispell many of the "myths" about tires so people will be better informed.
Tires are a highly engineered product that face some of the most severe environments - the road.
The vast majority of tire failures are caused by road hazards and lack of proper tire maintenance, not manufacturing defects.

Mark, As you know, on every vehicle sold in the US, there is a sticker – commonly called the tire placard - that lists the original tire size and the proper pressure for that size. The placard is usually
Sara, This is a complex issue with many facets. First, any time a vehicle sits, it is starting to get a flat spot. It is very temperature related. Clearly a week of sitting shouldn't cause an issue
Brooke, As you found out. M+ S means "Mud and Snow" - an All Season. BSW means "Black Sidewall". So these are not in conflict. My best guess is that they are the same. But to be sure that replacing
Dean, A 2000 Chevy Trailblazer has a bolt circle of 5 X 120.7mm and a 1999 Jeep Laredo has a bolt circle of ...... well my book doesn't list the model that way, but the 2 choices for Jeeps of that year
