Using my engineering degree to prove why you’re bad at saving tires in iRacing

In this Halloween-themed iRacing tutorial, DJ Yee-J dives into the “scary” concept of physics in tire saving techniques on oval tracks. Dressed up in a cars-themed costume, they break down why an early turn-in, or “anti-arc” line, helps with tire management by leveraging banking forces, friction, and normal forces on the car. This unconventional approach is explained using simple physics concepts, aiming to improve your tire-saving strategy in iRacing.

• Balancing understeer and oversteer is a key part of tire management. What unique strategies do drivers use to balance these forces and achieve an ideal, neutral steering approach on the track?
• When friction builds up, tires wear down quickly, yet friction is necessary for cornering. How do concepts like “static friction” and “normal force” help us understand the delicate balance needed to manage tire wear?
• The gravitational pull and centrifugal force are constant on banked tracks, but there’s a trick to counteracting these forces to optimize tire wear. What strategies can drivers use to manage these forces through tire-saving techniques?
