Why does Porsche tire inflation matter?

Even a tiny decrease in tire pressure could impact your safety and fuel economy. Maintaining proper tire pressure can help increase fuel economy, improve braking time, and boost tire lifespan.

Why are there numbers on the side of my Porsche 911 tires?

Your tire sidewall gives you information about load carrying capacity, speed rating, treadwear, traction, and tire size. Talk to one of our tire technicians to learn how to read the numbers on your tire!

Is there an easy way to check Porsche 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 Porsche 911 tires.

Get the Right Tires for 2021 Porsche 911

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 why you should head our way when it's time to put new tires on your 2021 Porsche 911. Firestone Complete Auto Care is the tire shop of choice for Porsche 911 tire options. Whether you want tire that's made to improve fuel economy, take tight corners, or handle off-road terrain, you'll find good tires that match your budget.

View the recommended tires for your 2021 Porsche 911, plus important information about Porsche 911 tire pressure, tire size, and speed rating. Come to Firestone Complete Auto Care for tires and you'll experience our best service. As one of our tire managers, Ruben, says, “I make sure you know which tire is the best fit for your car, not only for performance but safety.”

Other than getting the proper tire size, you also want to think about a couple of other things when getting new Porsche 911 tires like where and how you drive, and what tire brand you trust most. If you live in south Texas, you probably won't need studded snow tires anytime soon. Somewhere like Colorado or even Kansas is a different story. You may want to invest in a set of Porsche 911 snow tires for one part of the year, and all-season tires for the rest of the year.

When evaluating your driving conditions, think about where you live (countryside vs. city vs. mountains) and the kind of unexpected weather you're likely to experience. It's not uncommon for drivers in states that experience all four seasons to buy more than one set of tires. one for winter and one for summer. That way, they can maximize their Porsche 911'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 Porsche 911? Adventuring where other vehicles can't? If you're an avid off-roader who yearns to pioneer new paths, you have very different tire needs than a highway commuter who doesn't hit the hills very often. You'll want a tire that can handle dirt, gravel, stone, sand, and more. A larger tire with stiff sidewalls and a wide tread pattern can help prevent punctures and encourage stability on bumpy roads. But if you mostly drive around the city, a Porsche 911 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 Porsche 911 tires online. You're only a few clicks away from finding the right 2021 Porsche 911 tire for your needs.

Porsche 911 Tire Brands

Firestone Complete Auto Care has plenty of good Porsche 911 tire brands for you to choose from. Two of them are Firestone and Bridgestone. Porsche 911 Firestone tires are tires you can count on. Harvey Firestone founded the Firestone Tire & Rubber Company in Akron, Ohio in 1900. He was a passionate inventor from the start. Firestone recognized the untapped potential for auto tires, so he started producing and testing passenger, truck, and farm tires. Fun fact: in 1908, Firestone's company introduced the first all-rubber, non-skid tire! Thanks to Harvey Firestone, Firestone Tires has been committed to staying ahead of the curve since day one. Firestone is now one of the largest tire manufacturers in the world with 8,000 different tires for a variety of vehicles — including the 2021 Porsche 911.

Bridgestone is another smart move for Porsche 911 tires. Shojiro Ishibashi founded The Bridgestone Tire Company Ltd. in Japan in 1931. His company merged with The Firestone Tire & Rubber Company in 1990. Today, Bridgestone Tires has more than 55,000 employees and 50 production facilities throughout the Americas. The company remains an international leader in tire and rubber technology, delivering outstanding tires, service, and more to drivers worldwide. In the words of founder Shojiro Ishibashi, Bridgestone is dedicated worldwide to "serve society with superior quality." That means you can buy superior quality Bridgestone tires for a 2021 Porsche 911 and drive with peace of mind!
