What is the Recommended BMW Tire Air Pressure?

If you want to keep your BMW running like a dream on the St Louis roads, a little maintenance will go a long way. Learning how to check tire pressure is a simple and fast DIY task that can keep your BMW tires in top shape. What is the ideal BMW tire air pressure? Most BMW models require 32 PSI (pounds per square inch) of pressure, but it’s a good idea to double-check. You can either look in your owner’s manual or look for a sticker on the driver’s side door jamb for information specific to your model. Keep reading to find out how to check your tire pressure like a pro, and visit us at BMW of West St Louis for all your automotive needs.

Why is Air Tire Pressure Important?

Before we dive into the ins and outs of tire air pressure, why is tire air pressure so important anyway? Your tires were designed to perform their best at a specific pressure. That means you’ll get the best handling, the best fuel economy, and the safest performance at the recommended reading. Keeping your BMW tires properly inflated offers all the following benefits:

• Reduces the risk of flat tires or blown-out tires
• Extends the lifespan of your BMW tires by reducing friction
• Improves fuel economy by as much as 3.3%, according to the Department of Energy

How to Check Tire Pressure

There are two ways to keep tabs on your BMW tires in Ladue. Most new BMW models are equipped with a tire pressure monitoring system, which displays the current tire pressure of all four tires on your dashboard. However, you can also grab a tire pressure gauge to check each tire manually. Here’s how to check tire pressure in just a few minutes:

1. If you’ve been driving, give your car some time to cool down. The heat of the tire can lead to an inaccurate reading.
2. Unscrew the valve stem cap and place it somewhere safe.
3. Place a tire gauge onto the valve stem and press down.
4. Read the display. You’re looking for around 32 PSI, depending on the model.
5. Remove the gauge.
6. If your tires are overinflated, press down the center plunger in the valve stem to let air out and recheck. 
7. If your tires are underinflated, add enough air to bring them up to the recommended level and recheck. 
8. Replace the valve stem cap once your pressure is set.
9. Repeat with all four tires once a month.
10. Check your BMW spare tire once every six months. 

More BMW Tire Care Tips

Now you have your maintenance schedule and a tire pressure gauge on hand, but what else should you know about taking care of your BMW tires around Ballwin? Here are a few extra tips from our service technicians:

• Visual Inspections: Take a good look at all four tires from time to time. Look for tread wear, puncture marks, or cracks in the sidewalls. Check your BMW spare tire twice a year as well.
• Pressure Leaks: Are your tires losing air pressure quickly? This could be a sign of a leak somewhere. Schedule a multi-point inspection at the service center.
• Pro Maintenance: Tire rotations, wheel alignments, and wheel balances will all prolong the lifespan of your BMW tires. Check your owner’s manual to see what service interval is recommended.
• Temperature Changes: Your tire air pressure is also greatly affected by the season. If the temperatures drop quickly in Manchester, your air pressure could also drop overnight! Don’t be surprised if you need to top off your tires a little more frequently in the colder months.
