Get the Right Tires for 2008 BMW 550i

Shopping for tires can be overwhelming, but not when you're equipped with the right information. That's why you should head our way when it's time to put new tires on your  2008 BMW 550i. Firestone Complete Auto Care is the place to go for BMW tires in all sizes, for all seasons. Whether you need a tire that's designed to handle diverse terrain, improve fuel-efficiency, or take tight corners, you'll find good tires that match your budget.

View BMW-recommended tires for your 2008 550i, plus important information about BMW 550i tire size, tire inflation, and speed rating. Take it from one of our tire technicians, Brianna: "You want to find the correct size for your tire. It matters in alignments and keeping your vehicle driving the way it’s supposed to.”

Other than getting the proper tire size, you also want to consider a handful of other factors when buying new BMW 550i tires like how and where you drive, and how much you want to spend. If you live in south Texas, you probably won't need studded snow tires anytime soon. In Colorado, though, there's a good chance you'll want BMW 550i snow tires for a good portion of the year, and maybe even all-season tires for year-round comfort and versatility.

When thinking about your driving conditions, consider where you live (mountains vs. city vs. countryside) and the kind of weather can catch you off-guard. (Watch out Tornado Alley!) Drivers in states that fully experience all four seasons often buy two sets of tires: one set for winter, one set for summer. That way, they can maximize their BMW 550i's performance during both seasons. Other drivers buy one set of all-season tires instead. That way they don't have to return to the tire shop and their vehicle is always ready for sun, rain, and light snow!

Driving style is next on the list to think about when buying tires. Do you enjoy challenging the limits of your BMW 550i? Going where no vehicle has gone before? If you're a big off-roading fan you forges paths where others can't, you have very different needs than a long-distance commuter who sticks to the highway. You'll want strong tires that can take on sand, stone, gravel, dirt, and more. You might want to look at bigger tires with stiffer sidewalls and wider tread patterns to help protect against punctures and maintain balance in irregular road conditions. But if you're comfortable in the city and suburbs, a BMW 550i tire that offers low rolling resistance for better fuel efficiency might be exactly what you want. Visit your local Firestone Complete Auto Care for help selecting the tire that's right for you, or get started by browsing tires that fit your vehicle. You can buy 2008 BMW 550i tires online now!

2008 BMW 550i Tire Q&A

Inspecting and caring for your tires is one of the best ways to help them last. Get answers to common BMW 550i tire questions and learn how to care for new tires.

  • Why does BMW tire inflation matter? A small decrease in tire pressure can have a big impact on your driving. Maintaining proper tire pressure can help improve braking time, increase fuel economy, and boost tire lifespan.
  • Why are there numbers on the side of my BMW 550i tires? Your tire sidewall numbers tell you the recommended load carrying capacity, speed rating, treadwear, traction, and tire size. Talk to a tire technician to learn how to read BMW tire numbers.
  • Can I check the tread depth on my BMW tires at home? Grab a penny. Hold the so that Abe Lincon's head is facing you and his hair is pointing toward the ground. Then, place the penny into a tread groove. If you can see the top of Abe’s head, your tread is shallow and it might be time for new BMW 550i tires.
