What is the appropriate tire pressure for a Vespa?

Vespa tire pressure is generally normal between 2.2—2.5 bar, with the front tire pressure maintained at 2.2 bar and the rear tire pressure at 2.5 bar. Below is relevant information about car tire pressure: 1. Normal range of tire pressure: The tire pressure for passenger car tires is usually between 2.3~2.8 BAR, and as long as it is within this range, it is safe. 2. Reference factors: The impact of seasonal temperature changes on tire pressure can be ignored. For empty or half-loaded conditions, refer to the lower limit of the recommended inflation pressure sticker on the vehicle as a reference value. For full load, use the upper limit of tire pressure as a reference value. In addition to these factors, cold tires and hot tires can cause deviations in measured tire pressure values. Therefore, to ensure accurate tire pressure readings, always measure when the tires are cold.

Will a Phone Get Damaged If Left in a Hot Car?

Leaving a phone in a car during summer may cause it to explode. Here are the details: 1. Exposing the phone to sunlight: If the phone is exposed to direct sunlight at high temperatures, it may explode. The phone contains a battery, and prolonged exposure to sunlight can lead to an explosion. Even if it doesn't explode, it can cause significant damage to the battery. Place the phone in a shaded area to avoid direct sunlight. If the phone overheats, you can place it near the air conditioning vent to cool it down quickly and prevent battery damage. 2. Items to avoid leaving in the car during summer: Lighters: Small and easy to forget, yet highly dangerous. They contain liquid butane, and exposure to sunlight increases internal pressure, leading to explosions. Bottled water: Stored in a sun-exposed car for a certain period, it can release harmful substances. Continued consumption may not quench thirst but can harm health and cause discomfort. Glasses: Especially reading glasses, as their convex lenses can focus light, potentially causing a fire. Perfume (in glass bottles): Perfume evaporation produces flammable gases, with a critical packaging point of 49 degrees. Tests show that in an unshaded car at noon in summer, temperatures can reach 65 degrees in 15 minutes, easily causing an explosion. Electronic devices: Phones exposed to sunlight may develop mechanical issues, and chargers can explode if overheated from prolonged exposure.
