What is the difference between 195 tires and 205 tires?
2 Answers
195 tires and 205 tires differ in the following aspects: 1. Tire size: The diameter of a 195 tire is 634.5mm, while that of a 205 tire is 631.9mm, making the 195 tire 2.6mm taller than the 205 tire. 2. Aspect ratio: At the same tire height, the 205 tire has a lower aspect ratio than the 195 tire, meaning it offers better handling performance. 3. Contact patch area: The 205 tire is 10mm wider than the 195 tire, resulting in approximately 5% more resistance. At low speeds, without considering wind resistance, the 205 tire naturally consumes about 5% more fuel than the 195 tire.
I find the topic of tire width quite fascinating. A 195 tire is 195 millimeters wide, while a 205 tire is 205 millimeters wide. A 10-millimeter difference might not seem like much, but it makes a significant impact when driving. The wider 205 tire has a larger contact patch, providing better grip during turns, especially at high speeds where the car feels more stable. It also reduces the likelihood of slipping in rainy conditions. However, there are clear downsides: increased rolling resistance. After switching to 205 tires, my fuel consumption rose by one to two liters, which definitely hurt my wallet. The tires themselves might also be more expensive, and if the rims aren’t compatible, installation can be troublesome—sometimes even causing the tires to rub against the body. Personally, I prioritize comfort, so I stick with the factory-fitted 195 tires. Upgrading to 205 requires measuring the rim size first to ensure safety—otherwise, it might do more harm than good. I’d recommend consulting a mechanic before making any changes.
