What is the difference between 195 tires and 205 tires?
2 Answers
The differences between 195 tires and 205 tires are the tire size, aspect ratio, and contact area. Below are the specific explanations for these differences: Tire size difference: The diameter of a 195 tire is 634.5mm, while the diameter of a 205 tire is 631.9mm. The diameter of a 195 tire is 2.6mm larger than that of a 205 tire. Aspect ratio difference: At the same tire height, the 205 tire has a lower aspect ratio than the 195 tire, meaning it offers better handling performance. Contact area difference: 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.
The difference between 195 and 205 tire widths is 10 millimeters. The narrower 195 tires are particularly fuel-efficient for city driving. I usually use 195 tires for my daily commute on the elevated highways, and they allow me to travel dozens of kilometers more on a full tank. However, 205 tires are more stable on highways during rainy days, with stronger grip and no slipping, although they consume slightly more fuel. If you frequently drive long distances, choosing 205 tires provides more peace of mind, as they offer shorter emergency braking distances. When changing tires, remember that both tires on the same axle must be the same width, and the rims must also match. The 195 tires fit perfectly with 6J rims, while 205 tires require 7J rims. Wider tires are also more expensive; four 205 tires cost several hundred yuan more than 195 tires, so long-term fuel consumption differences should be considered.
