On horizontal curve, if the pavement is kept horizontal across the ali...
When a pavement is kept horizontal across the alignment i.e. no superelevation is provided, then the pressure on outer tyre is more than that of inner tyre because the centrifugal force acts radially outward and friction will oppose this centrifugal force.
Consider a vehicle travelling on a horizontal curve with no super elevation
Vehicle is in rotational equilibrium i.e. ∑M0 = 0
Fy + PIx = P0y
Where,
p = centrifugal force on vehicle acting radially outward, F = friction o/w tyre and road acting inward, P0 = outer tyre force, PI = Inner tyre force, and W = weight of vehicle
⇒ Outer tyre pressure is greater than inner tyre pressure.

On horizontal curve, if the pavement is kept horizontal across the ali...
Introduction:
In horizontal curves, the pavement is designed to maintain a horizontal alignment across the curve. This means that the surface of the road remains flat, without any incline or decline, throughout the curve. The pressure on the outer wheels of a vehicle traveling on a horizontal curve is greater than the pressure on the inner wheels.
Explanation:
When a vehicle moves through a horizontal curve, it experiences two types of forces: centrifugal force and gravitational force. Centrifugal force pushes the vehicle away from the center of the curve, while gravitational force pulls the vehicle downwards. These forces cause the vehicle to tilt towards the outer side of the curve.
Effect of Tilt:
When the vehicle tilts towards the outer side of the curve, the weight of the vehicle is distributed unevenly between the inner and outer wheels. The outer wheels bear a greater load compared to the inner wheels. This uneven distribution of weight results in higher pressure on the outer wheels.
Reasoning:
The pressure on a wheel is the force acting per unit area. As the weight of the vehicle is distributed unevenly, the pressure on the outer wheels will be greater than the pressure on the inner wheels. This is because the weight is concentrated on a smaller contact area for the outer wheels.
Consequences:
The higher pressure on the outer wheels can lead to uneven tire wear and reduced tire life. It can also result in increased rolling resistance, which negatively affects vehicle efficiency and fuel consumption. Additionally, the higher pressure on the outer wheels can lead to reduced grip and stability, increasing the risk of accidents.
Conclusion:
In horizontal curves, where the pavement is kept horizontal across the alignment, the pressure on the outer wheels of a vehicle will be more than the pressure on the inner wheels. This is due to the uneven distribution of weight caused by the vehicle tilting towards the outer side of the curve. It is important to consider this factor in the design and maintenance of horizontal curves to ensure safe and efficient transportation.
