Hypothetical question concerning vectors of steering?

Click For Summary
SUMMARY

The discussion centers on the dynamics of tire wear during a left swerve in a vehicle, specifically addressing the effects of load distribution and G forces. It concludes that during a left swerve, the left side of the car experiences slightly more downforce at the contact patches, leading to increased wear on the left tires. The load distribution is influenced by the front/rear weight distribution and the stiffness of the suspension. In a rear-wheel drive car, the dynamics may vary due to different weight distributions and load factors.

PREREQUISITES
  • Understanding of vehicle dynamics and tire wear
  • Knowledge of G forces and their impact on vehicle handling
  • Familiarity with front/rear weight distribution concepts
  • Basic principles of suspension stiffness and its effects on load
NEXT STEPS
  • Research "Vehicle Dynamics and Tire Wear" for in-depth analysis
  • Study "G Forces in Automotive Handling" to understand their effects
  • Explore "Suspension Stiffness and Load Distribution" for practical applications
  • Investigate "Rear-Wheel Drive vs. Front-Wheel Drive Dynamics" for comparative insights
USEFUL FOR

Automotive engineers, vehicle dynamics researchers, and automotive enthusiasts interested in understanding tire wear patterns and vehicle handling during maneuvers.

Hypothetically:
-car is aligned properly
-crown has nothing to do with anything
-the steering wheel is on the Left and you weight generously 200lbs.

If you were to draw vectors and include G forces and everything you can think of for this incidence, what would you conclude?

You are going on a straight path, you see an animal and you quickly swerve to the left, which side would you experience the most wear on?

At the instant of the initiation of the swerve, where is the load L or R?

Cut the car in half.
Left vs. Right side of car experiences most wear?
Would this change on a Rear wheel drive car?

We had this discussion in an auto shop and I am not delighted to hear something that was so conter-intuitive that I'd just had to ask!

Left side of car has a bit more downforce at the contact patches than right side.

Do you mean tire wear? I'm not sure how wear relates to load factors (downforce, side load), squirming at the contact patch, slippage at the contact patch, ...

A the instant of of initiation of the swerve, the load factors are the same as going straight. It takes some small, finite amount of time before the side loads become non-zero.

The L / R distribution of the downforce depends on front / rear weight distribution and stiffness of the suspension. If the front / rear weight distribution is near 50% / 50%, then the right tire at the relatively "stiffest" end gets the most load, and the left tire at the relatively "stiffest" end gets the least load.
 
I figured it out now thanks for clarification =)
