Get the Right Tires for 2009 Cadillac STS
Finding the right tires can be quick and easy, especially when you have all the information you need to make a good decision. That's one reason it's a good idea to visit us when you're ready to buy new 2009 Cadillac STS tires. Firestone Complete Auto Care is the place to go for Cadillac 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 the right tires for your vehicle and budget.
View the tires Cadillac recommends for 2009 STSs, plus useful info about Cadillac STS tire size, tire inflation, and speed rating. Your vehicle can't drive correctly without the correct tires. As one of our tire technicians, Brianna, explains, "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 Cadillac STS tires like how and where you drive, and how much you want to spend. If you live in south Texas, you probably won't want to buy studdable snow tires. In Colorado, though, there's a good chance you'll want Cadillac STS snow tires for a good portion of the year, and maybe even all-season tires for year-round comfort and versatility.
Think about where you live (countryside vs. city vs. mountains) and the kind of unexpected weather you're likely to experience when evaluating your driving conditions. Drivers in states that fully experience all four seasons often buy two sets of tires: one set for winter, one set for summer. It's a smart way to capitalize on Cadillac STS's performance and safety throughout the year. Other drivers prefer the convenience of all-season tires. They make one trip to the tire shop and they're pretty much ready for rain, light snow, or sun!
Your personal driving style is the next factor to consider. Do you enjoy challenging the limits of your Cadillac STS? 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 tires that can stand up to dirt, gravel, stone, sand, 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 Cadillac STS tire that offers a smooth, quiet ride might be exactly what you need. Talk to a tire technician at Firestone Complete Auto Care for help choosing the best tire for you, or start shopping for Cadillac STS tires online. You're only a click or two away from a new set of 2009 Cadillac STS tires.
Good Tire Brands for Cadillac STSs
You have so many options when it comes to tire brands that work for Cadillac STSs. Firestone and Bridgestone are two of the most popular. Firestone tires for Cadillac STSs always deliver! Harvey Firestone founded the Firestone Tire & Rubber Company in Akron, Ohio in 1900. He was a boundary-pusher from the beginning. Firestone recognized the untapped potential for auto tires, so he started making and testing truck, passenger, and farm tires.

Firestone Tires has been passionate about leading the industry since day one, thanks to Harvey Firestone's industrious spirit. Firestone now makes about 8,000 different tires for all kinds of vehicles — including tires for 2009 Cadillac STSs.
Bridgestone is another top choice for Cadillac STS tires. In 1931, Shojiro Ishibashi founded The Bridgestone Tire Company Ltd. in Japan. In 1990, the company merged with The Firestone Tire & Rubber Company. Today, Bridgestone Tires has more than 55,000 employees and 50 production facilities throughout the Americas.

2009 Cadillac STS Tire Q&A
Inspecting and caring for your tires is one of the best ways to help them last. Get answers to common Cadillac STS tire questions and learn how to care for new tires.
-
Why does Cadillac 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.
-
What do the numbers on my Cadillac STS tires mean? 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 Cadillac tire numbers.
-
Is there an easy way to check Cadillac tire tread depth? 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 Cadillac STS tires.
