Answer to Question #288186 in Physics for SHOBAN

Question

A person wants to replace his vehicle’s tyres to a larger diameter/thickness. The driver askes your suggestion if there would be any changes to his vehicle after the replacement of the tyres. Provide your knowledgeable opinion on the changes that would occur if the driver were to change his vehicle’s tyres from a diameter of 175 mm to 215 mm. Your answer should exemplify the following changes to the vehicle;

I. Centripetal force

II. Torque

Acceleration

Answer 1

The centripetal force will remain the same if the track width is the same, applied to a higher tire size, this will increase the probability of tipping over.

The resistive torque of the wheels will increase the load on the driveshafts, which will make them less reliable.

The acceleration of the car may increase or decrease, it depends on the torque of the engine, because the same torque of the engine applied to wheels of greater diameter and larger mass may result in smaller final acceleration as compared to wheels of smaller diameter and mass.
