Standard tire pressure for the Chevrolet Equinox: generally 2.3~2.5 bar. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, leading to internal cracks, blowouts, and potential tire bursts. Hazards of insufficient tire pressure: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, posing safety risks; Increases movement in various parts of the tire, leading to abnormal overheating due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination, cord breakage, and excessive friction with the rim, resulting in damage and abnormal wear at the bead area; Multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire bursts; Increases tire deformation, making the sidewalls prone to cracks and generating flexing movements, leading to excessive heat, rubber aging, cord fatigue, breakage, and increased tire contact area, accelerating shoulder wear.

I've been driving a Ford Explorer for several years, and the normal tire pressure is between 35 to 40 PSI, with the most accurate reading when the tires are cold. The label on the door jamb provides detailed specifications, usually recommending around 35 PSI as optimal. In summer, higher temperatures can naturally increase tire pressure slightly, but it's best not to exceed 40 PSI to avoid increased risk of a blowout. In winter, when it's colder, I lower the pressure a bit to prevent the tires from becoming too stiff and affecting ride comfort. Before hauling heavy loads or going on long trips, I inflate the tires to around 37 PSI for better stability. Underinflated tires significantly increase fuel consumption, cause faster wear on the tire sidewalls, and shorten their lifespan. Overinflated tires reduce shock absorption, making bumps and potholes more noticeable. I make it a habit to check the tire pressure monthly using a portable gauge in my home garage—no need to constantly visit the dealership. Remember, timely maintenance helps prevent small issues from becoming big problems.

As a family car owner, safety is my top priority. The normal tire pressure for the Explorer is 35 PSI, and the tire pressure label on the door clearly indicates the recommended value. If the tire pressure is too low, it can cause skidding, especially when making high-speed turns in the rain, which may lead to loss of control; if it's too high, the tire grip weakens, and going over speed bumps can make the ride uncomfortable for the kids. Before long road trips, I always do a quick check at the gas station, using the free air pump to adjust to the optimal 35 PSI. Maintaining the correct tire pressure can also save about 10% on fuel, and the extra savings go into the kids' education fund. During regular maintenance, I remind the technician to check it as a preventive measure against potential issues.

Tire pressure directly impacts expenses, with the Explorer's optimal 35 PSI saving fuel and hassle. Low pressure increases rolling resistance, a 1% rise in fuel consumption burns money; high pressure causes rapid center tread wear, costing hundreds more for premature replacement. I use a digital tire gauge, checking during car washes to maintain 35 PSI. Staying within standard range extends tire life by over two years, reducing repair errands. Economical and practical, wealth accumulates from details.
