How thick is the sidewall of a Michelin 235 tire?
2 Answers
The sidewall thickness of a Michelin 235 tire is 5mm. Functions of car tires: Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions; transmit traction and braking torque to ensure good adhesion between the wheels and the road surface, improving the car's power, braking, and passability; work with the car suspension to cushion the impact during driving and dampen the resulting vibrations; prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure driving safety, handling stability, comfort, and energy efficiency. Precautions for tire use: Check tire wear; regularly check tire pressure; remove debris from tire treads; avoid rapid starts, emergency braking, or sharp turns while driving; avoid hitting curbs, etc.
When it comes to the sidewall thickness of Michelin 235 tires, I've found it mainly depends on the aspect ratio, which is the number in the size code like 235/45. The 235 means a width of 235 millimeters, and 45 represents an aspect ratio of 45%, so the sidewall height would be 235 multiplied by 0.45, approximately 105.75 millimeters. However, Michelin offers various tire models like Pilot Sport or Energy Saver, each with different designs and aspect ratios ranging from 40 to 65. This means the thickness could vary between 94 to 152.75 millimeters. Thinner sidewalls enhance handling and provide more precise cornering but are more susceptible to damage on rough roads. Thicker sidewalls offer better comfort and durability, making them ideal for daily commuting. With years of experience in cars and having changed several sets of tires, I always advise friends to first check the vehicle manual and the markings on the tire sidewalls. Safety comes first—never swap tires carelessly as it can affect balance. Choosing the wrong tires not only increases fuel consumption but also poses risks, so it's crucial to be careful.
