How thick is the sidewall of a 225 tire?

146.25 millimeters. The 225 represents the tire's section width of 225 millimeters, and the 65 represents the tire's aspect ratio, which is the percentage of the tire's section height divided by the tire's width. The tire's section height is the thickness of the tire's sidewall. For a 225/65 tire, the sidewall thickness is 225 × 65% = 146.25 millimeters. Below is a detailed introduction to Michelin's tire series: Pilot: A sports tire focused on high performance and handling, but with higher road noise, lower comfort, and a wear index around 300, making it less durable. It is mainly suited for high-performance sedans or sports cars. Primacy: Michelin's representative product for comfort and quietness, with models like Primacy-LC Bo Yue and Primacy-HP. The LC Bo Yue is positioned for quiet comfort and fuel efficiency, while the HP focuses on quiet comfort and handling. The latest 3ST model emphasizes safety, quietness, and comfort. Energy: Focused on economy and durability, this series offers excellent wear resistance, wet performance, and environmental performance, with models like XM1+, XM2, and MXV8. The XM1+ is positioned for economy and durability, the XM2 for durability and safety, and the MXV8 offers better comfort and handling. Latitude: Designed for SUVs, featuring excellent off-road performance, comfort, wear resistance, and durability, expanding Michelin's product coverage in the SUV tire market.

I usually drive a compact car with 225-width tires, and the sidewall thickness is quite crucial. I remember when I first bought the car and had to replace the tires, I specifically asked the mechanic about this. They said the thickness generally ranges between 6 to 10 millimeters, but it depends on the brand and type. For example, the summer tires I use are about 7 millimeters thick, with sidewalls made of a nylon and rubber composite. Thinner sidewalls offer a more comfortable ride but are more prone to bulges when hitting potholes, while thicker ones provide better impact resistance. Once, I hit a small stone on the highway, and the sufficient thickness prevented any damage. I’d advise everyone not to focus solely on tire width—sidewall structure affects safety, and regular checks for wear and tire pressure are essential.

As a car enthusiast who frequently tinkers with my vehicle, I've noticed that the sidewall thickness of a 225 tire isn't a fixed number. It's closely related to the number of internal cord layers – for instance, a 4-ply tire might have around 7mm thickness, while a 6-ply could exceed 9mm. The 45% aspect ratio is used to calculate sidewall height and isn't directly related to thickness. Through testing different tire brands, I've found budget tires tend to be thinner at about 6mm, while performance tires are thicker at around 10mm, with noticeable driving differences. Thinner tires offer weight savings and better fuel economy but transmit more vibration over speed bumps. The ideal choice is a medium thickness of 7-8mm for the best balance between durability and comfort.

Having driven for over a decade, I never take tire safety lightly. The sidewall thickness of 225 tires typically ranges between 6mm to 12mm – too thin and you risk blowouts. I personally check tire pressure regularly and inspect sidewall scratches to prevent excessive wear. For beginners selecting a car, I recommend reviewing tire specifications to choose brands with around 8mm thickness, which offers better durability against daily impacts.
