Cadillac's normal tire pressure ranges between 2.3 to 2.5 bar, which can be directly monitored through the dashboard. Below is relevant knowledge about tire pressure adjustment: Adjustment based on road conditions: On rough roads with significant bumps, it's advisable to slightly reduce the tire pressure by 0.1-0.2 bar from the standard tire pressure. For long-distance high-speed driving, the tire pressure should not be too low; it's recommended to increase the pressure by approximately 0.2 bar from the standard lower limit. Adjustment based on tire condition: For new tires, the pressure can be increased by about 0.2 bar from the standard tire pressure. For old tires, it's appropriate to slightly decrease the pressure according to the standard. If the tires are severely worn, the pressure should be set to the lower limit of the standard tire pressure.

When I first started driving my Cadillac XT5, I specifically checked the manual for tire pressure, which stated around 32 PSI when cold, with front and rear tires being roughly the same. I must remind you, never measure the pressure right after driving, like right off the highway—it won't be accurate. It's best to wait at least three hours after stopping for a precise reading. Temperature changes have a big impact; in winter, I add 1-2 PSI because the air contracts and reduces pressure. I prefer using a digital tire gauge for checks—simple and cheap, I keep one in the trunk as a backup. Neglecting this can lead to uneven wear, especially faster wear on the inner side of the front tires, and replacing a whole set isn't cheap. Fuel efficiency is also affected; too low pressure can increase fuel consumption by 0.5 liters per 100 km, which adds up over time. I recommend new owners get into the habit of checking monthly—both the door frame label and the manual list specific values, which vary slightly by model but shouldn't deviate too much.

Speaking from a safety perspective on tire pressure, my ten years of driving experience tell me that Cadillac's recommended pressure is generally between 32 to 35 PSI, with larger SUVs like the Escalade requiring slightly higher pressure. Insufficient pressure increases braking distance, raising accident risks, especially in rainy conditions or on curves. Measuring cold tires is a fundamental rule, and if the pressure falls below 28 PSI, it's time to refill. I use a portable pressure gauge to check every two weeks, ensuring even wear and preventing blowouts. Low pressure also increases rolling resistance, causing tires to overheat at high speeds and shortening their lifespan. Long-term neglect can lead to suspension issues, affecting driving stability. Vehicles equipped with tire pressure monitoring systems have alarms, but sensors need calibration—don't rely solely on them. For beginners, remember: safety first. Proper tire pressure control can reduce accident risks.

According to car enthusiasts' sharing, the tire pressure for Cadillac varies by specific model and year. For example, the CT5 recommends around 33 PSI, with the unit possibly being PSI or kPa (32 PSI is approximately 220 kPa). Don't rely on estimates; always measure when the tires are cold, preferably using a digital tool. Front and rear tire standards may be the same, with SUVs sometimes having slightly higher rear tire pressure. A short-term difference of 1-2 PSI is fine, but long-term deviations can affect handling and tire wear. The manual or the label on the door frame is the best reference. Simple practice: Check the pressure monthly to ensure stability.
