Question: 1 / 400

When compensating for road crown, how should the left and right side tires be adjusted?

Both tires should be adjusted to have toe out

Left tire with slight toe in and right tire with toe out

Right tire with slight toe in and left tire with toe out

Left tire with slight toe out and right tire with toe in

When compensating for road crown, adjusting the left tire to have slight toe out and the right tire to have slight toe in helps balance the vehicle's handling and tracking. Road crown refers to the slight incline in the road towards the gutters, which is designed for drainage but can affect how a vehicle travels along that surface.

By setting the left tire to toe out, it allows that side of the vehicle to slightly steer away from the road's incline, counteracting the tendency to pull toward the left side. Conversely, having the right tire with slight toe in helps it maintain better contact with the road, allowing for more stability and control as it adheres to the incline naturally.

This adjustment technique is essential for ensuring that the vehicle tracks straight and does not veer off course due to the road's design. It provides a more balanced driving experience, reduces tire wear, and improves overall vehicle safety.
