SLOWER SPEED PSI IMPACT

AG TIRE TALK KEY TAKEAWAYS

QUESTION: Why is a tire, when run at slower speed, able to carry same load at lower air pressure?

MICHELIN: “The structural integrity of the tire is being compromised, more often as speed increases, and more significantly as air pressure decreases.”

ASCENSO: “The central subject for this question has to do with the law of coefficient of friction- the faster an object moves against another object the more heat is built up, and all tire folks know that heat is the worst enemy of a tire.”
