How soon should I have my flat tire repaired?

A flat tire that’s not addressed can take a terrible toll on the rest of your car. Until you have it repaired or replaced, drive your WRX STI as little as possible to reduce your risk of damage to the wheels and alignment – or further damage to that already struggling tire!

Can I use an emergency/temporary sealant to fix my Subaru's flat tire?

A temporary sealant may be able to help you get to a repair location safely. But temporary or emergency sealants could possibly damage TPMS sensors, and in some cases may even void the warranty on your Bridgestone or Firestone tires. If your tire needs extensive repair, sealant can add time and labor costs to the process.

Can’t I just keep my spare tire on for a while?

While this sounds great in theory, keep in mind that most spare tires are not designed for distance or speed. The compact spare tire that most likely sits inside your 2021 Subaru WRX STI is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Who offers Subaru WRX STI tire repair?

Your local Firestone Complete Auto Care can generally take care of most Subaru WRX STI tire repairs. However, it depends on the severity of the damage.

What can cause WRX STI tires to keep losing air?

If your WRX STI tires are always losing air, you may have a puncture, damaged wheel, or leaking valve stem.

Is it necessary to replace all four Subaru WRX STI tires at once?

While it may not always be necessary to replace all four tires on your WRX STI, it’s advised you replace them in pairs or all at once to ensure optimal safety and performance. Having two new tires and two worn tires can put you at risk since the worn tires might not have as good of traction as the new ones. Reference your owner’s manual to see if you will need to replace all four tires due to a large difference in tread.

Repairing Your Subaru WRX STI Tire

Cities are growing. New roads are being built, and old ones are getting a face lift. Everywhere you look, it seems construction is in progress! New progress is exciting, but the road debris it leaves behind may mean trouble for your tires. Firestone Complete Auto Care is here for you when your 2021 Subaru WRX STI needs flat tire repair or inspection. There’s a chance your tire could be plugged and patched (rather than replaced). Our technicians can inspect your tire and let you know if it is safe to repair. We’ll begin by taking a look at where the damage is, the type and extent of the tire damage, and how all of your tires are wearing.

If we determine that your 2021 Subaru WRX STI tire can be safely repaired, the repair process is actually fairly simple: (1) Remove the tire from the wheel for inspection and repair, (2) use a filler to close up the puncture (this is to keep moisture from getting in), and (3) re-seal the inside lining of your tire so that air won’t escape.

Tire Replacement for Your Subaru WRX STI

Unfortunately, some 2021 Subaru WRX STI tire damage can’t be effectively repaired. Even if your tire damage is minor, if your tires have less than 2/32nd inch of tread remaining, a repair isn’t possible (or safe). At this tread depth, the tire is worn out and must be replaced. If your tire is not yet worn down, there are other forms of damage that simply can’t be repaired, like a tire with a puncture larger than ¼ inch in diameter; a tire with a puncture or damage outside the tread area; a tire with two or more punctures that are less than 16 inches away from each other; and major cuts or separated treads.

Depending on what Subaru recommends for your car, you’ll want to consider purchasing one new tire, two new tires, or a new full set. For example, it’s usually recommended that you replace all four tires at the same time on AWD vehicles. Why? Because having four identical tires is vital for the AWD system to perform like it’s supposed to. Just replaced your tires and only one is damaged? You may not need to buy another new full set after all. It’s possible that you will only need to replace the tire that’s damaged – just make sure it’s the same size, type, and brand as the rest of your tires. Still not sure how many tires to replace or what kind to buy? A trained tire technician at Firestone Complete Auto Care is ready and waiting to answer your questions.

Subaru WRX STI Tire Inspection

A flat tire is a surefire sign of tire damage, but other indicators of tire issues aren’t so easy to spot. Tire damage can also show itself through subtle symptoms, like dents in your wheel rims, excessive noise coming from the exhaust system, bumps or bulges in tire sidewalls, or even leaks underneath the car. Stay ahead of potentially dangerous tire issues. Bring your 2021 Subaru WRX STI in for a tire inspection.
