Is a tire pressure of 2.8 considered normal?

[StQuinn]

A tire pressure of 2.8 is not normal. The standard tire pressure range is between 2.3 and 2.5 bar. The effects of excessive tire pressure include: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Steering wheel vibration and deviation, reducing driving comfort; 3. Accelerated wear on the central tread pattern of the tire, shortening tire lifespan; 4. Increased body vibration, indirectly affecting the lifespan of other components; 5. Excessive stretching deformation of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; 6. Decreased tire pressure resistance, leading to internal cracks and blowouts.

I've been driving for 15 years and have deep experience with tire pressure. Whether 2.8 bar is normal depends on your car model and specific conditions. Generally, small cars recommend between 2.2 to 2.5 bar. If it's too high, the tires become stiff, leading to a bumpier ride, increased driving difficulty, and higher risk of skidding in rain. In summer heat, tire pressure rises quickly—2.8 bar on highways accelerates wear, shortens tire life, and raises the risk of blowouts. Check your door frame label or owner’s manual for the official recommended value—don’t adjust by feel. If too high, release some air; if too low, add air to maintain balance, extend tire life, and reduce unexpected repair costs. Keep a portable air pump in your car and check monthly when tires are cold for accuracy. Make it a habit—it protects safety and saves money.

I think the 2.8 bar tire pressure should be considered from a fuel-saving perspective. As a daily commuter who frequently drives on highways, fuel efficiency is a priority. Higher tire pressure reduces rolling resistance, potentially saving around 5% in fuel consumption, which is quite tempting. However, excessively high pressure accelerates wear on the center of the tires, leading to replacement in less than a year and higher costs, which ultimately backfires. The generally recommended range is 2.3 to 2.5 bar for a balanced approach, with higher values only suitable for heavy loads or SUVs. Taking our car as an example, while the standard is 2.4 bar, running at 2.8 bar does save fuel, but the tires wear out prematurely, doubling the cost. Measure tire pressure when the tires are cold, preferably in the morning, to avoid misleading readings. Low tire pressure also wastes fuel and poses risks. Installing a tire pressure monitoring system is a small investment with significant long-term benefits, ensuring both safety and efficiency. Don’t overlook the overall vehicle condition for minor gains. Regular maintenance, maintaining optimal tire pressure, ensuring smooth driving, and reducing maintenance hassles are the smart choices.

When I was a student driving out for fun, I encountered a tire pressure issue. 2.8 bar felt too high—usually, small cars are most comfortable below 2.5 bar. Driving felt too stiff and bumpy, which was uncomfortable and affected the driving pleasure. It might also damage the suspension system. If the pressure is too high, the tire's contact with the ground decreases, increasing braking distance, which is especially dangerous in rainy weather. The manual's recommended value is the best guide—don’t just copy others. A simple solution is to visit a repair shop for professional measurement and adjustment of tire pressure to ensure a safe and smooth trip. Developing this habit isn’t troublesome.
