That's why you should head our way when it's time to put new tires on your  1990 GMC S15. Firestone Complete Auto Care is the place to go for GMC tires in all sizes, for all seasons. Whether you want a tire that's built to handle diverse terrain, improve fuel-efficiency, or take tight corners, you'll find affordable tires that get the job done.

View the tires GMC recommends for 1990 S15s, plus helpful information about GMC S15 tire size, speed rating, and tire pressure. 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.”

Beyond the correct tire size, there are a couple of other factors to consider when buying GMC S15 tires like how and where you drive, and how much you want to spend. If you live in Louisiana, you probably won't want to buy studdable snow tires. Washington state or Montana is a different story, though. If you live in a state with some extreme seasonal shifts, you might want to switch between winter tires and all-season tires for the best performance.

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!) Many drivers who live in states that experience all four seasons choose to purchase two sets of tires: one set for winter, one set for summer. That way, they can maximize their GMC S15's performance during both seasons. 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!

Next, consider your driving style. Do you enjoy challenging the limits of your GMC S15? 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 sand, stone, gravel, dirt, and more. A larger tire with stiff sidewalls and a wide tread pattern can help prevent punctures and encourage stability in uneven road conditions. But if you plan on sticking around town, a GMC S15 tire that offers low rolling resistance for better fuel efficiency might be exactly what you want. Talk to a tire technician at Firestone Complete Auto Care for help choosing the best tire for you, or start shopping for GMC S15 tires online. You can buy 1990 GMC S15 tires online now!

Harvey Firestone founded the Firestone Tire & Rubber Company in Akron, Ohio in 1900. He was a passionate inventor from the get-go.

1990 GMC S15 Tire Q&A

Inspecting and caring for your tires is one of the best ways to help them last. Get answers to common GMC S15 tire questions and learn how to care for new tires.

  • Is GMC tire inflation important? 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 GMC S15 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 GMC tire numbers.
  • Is there an easy way to check GMC tire tread depth? Stay on top of your tire tread depth to help avoid a dangerous drive. You can check tread depth with a penny. Hold the penny so that Abraham Lincoln is facing you, then place your penny into a tread groove upside down. If you can see the top of Abe’s head, your tread is shallow and it might be time for new GMC S15 tires.
