What size can a 175/70/14 tire be replaced with?
2 Answers
175/70/14 tires can be replaced with 185/65/14. The specific explanation is as follows: The diameter of a 175/70/14 tire is 600.6mm, while the diameter of a 185/65/14 tire is 596.1mm, and the diameter of a 195/65/14 tire is 609.1mm. Therefore, replacing it with 185/65/14 would be more suitable. Relevant information is introduced as follows: 1. 185/60/14 tire: The diameter of a 185/60/14 tire is 577.6mm. If replaced with this, the difference in tire diameter is -3.83% (the error should be controlled within ±3%), so it is not recommended to interchange. 2. 185/65/14 tire: The diameter of a 185/65/14 tire is 596.1mm. If replaced with this, the difference in tire diameter is -0.67% (the error should be controlled within ±3%). When the actual vehicle speed is 100km/h, the speedometer will display 100.67km/h. 3. 195/65/14 tire: The diameter of a 195/65/14 tire is 609.1mm. If replaced with this, the difference in tire diameter is 1.5% (the error should be controlled within ±3%). When the actual vehicle speed is 100km/h, the speedometer will display 98.50km/h, so it is not recommended to interchange.
I have a small hobby for car modifications. For a tire size of 175/70/14, the width is 175mm, the aspect ratio is 70%, and the rim diameter is 14 inches. If you're getting new tires, it's best to keep the overall outer diameter similar so that the dashboard and braking system aren't affected. Generally, switching to 185/65/14 or 195/60/14 is fine, as the diameter change stays within ±3%. It depends on the car model, with SUVs being more flexible than sedans. I've personally tried a combination of 185/60/15, and upgrading to 15-inch rims looks cooler, but you need to confirm the bolt pattern and ET value match. Also, don't forget to consider handling when changing tires—wider tires offer better grip but may increase fuel consumption. It's recommended to consult a professional shop for advice.
