What is the appropriate tire pressure for 175 tires?
2 Answers
Car 175 tires should have a recommended tire pressure of approximately 2.3 to 2.5 bar. Below is detailed information about car tire pressure: 1. Overview: Tire pressure, strictly speaking, refers to the air pressure inside the tire. Tire pressure is like the blood pressure of a car, and its level plays a crucial role in the vehicle's performance and power. 2. Function: Tire pressure is an indicator of a car's load capacity. The load capacity of a car depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity.
As an experienced driver for many years, I always remind novice car owners not to determine tire pressure solely based on tire width. 175-width tires are mostly used on compact cars, typically recommended between 30 to 35 PSI, but the exact value should be checked on the vehicle's sticker or owner's manual. Excessive tire pressure can cause bumpy rides and loss of control, posing significant risks at high speeds; while insufficient pressure makes steering heavier, increases fuel consumption, and accelerates wear. The most accurate reading comes from checking when the tires are cold - just buy a $10 tire pressure gauge and do it yourself monthly. Neglecting tire pressure not only shortens tire lifespan but may also lead to blowouts. Spending one minute checking before driving can save repair costs and ensure safety. Remember to slightly release some air in summer when temperatures rise and tire pressure naturally increases, maintaining proper balance.
