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 D21 as little as possible to reduce your risk of damage to the wheels and alignment – or further damage to that already struggling tire!

Will a temporary sealant fix my Nissan'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 1990 Nissan D21 is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Where can I get my Nissan D21 tires repaired?

Your nearest Firestone Complete Auto Care is equipped to handle most Nissan D21 tire repairs, but it depends on how severe the damage is.

What is causing the tires on my D21 to keep losing air?

If your D21 tires are always losing air, you may have a puncture, damaged wheel, or leaking valve stem.

Can I replace just one or two tires on my Nissan D21?

While it may not always be necessary to replace all four tires on your D21, 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.

Nissan D21 Tire Repair

Cities are growing. Roads are expanding. There's construction around every corner! That means more tire-damaging road debris and flat tires. Firestone Complete Auto Care is here for you when your 1990 Nissan D21 needs flat tire repair or inspection. Our tire technicians can determine whether it's safe to plug and patch the tire, or whether it needs to be replaced. To start, we’ll consider the location of tire damage, the type of issue, the size and scope of the damage, and the amount of wear on your tires.

If a repair on your 1990 Nissan D21 tire is feasible and safe, we'll follow three basic steps to repair it: (1) Separate the tire from the vehicle wheel, (2) fill in the area that’s been punctured to prevent damage from moisture, and (3) secure and seal the inner tire liner to ensure the tire is airtight.

Nissan D21 Tire Replacement

Sometimes, 1990 Nissan D21 tire damage calls for more than a repair. For tires that have less than 2/32nd inch of tread left, a repair simply isn’t possible – even if the tire damage is minimal. Tires with this tread depth or less are no longer safe, so it’s time to replace the damaged tire. If your tire is not yet worn down, there are other forms of damage that simply can’t be repaired, like a tire puncture with a diameter bigger than ¼ inch; a puncture in the tire sidewall (or anywhere else that’s not within the tread area); multiple punctures that are too close together (less than 16 inches between them); and a tire with cuts or tread separation.

Sometimes, it's in your best interest to buy one, two, or four new tires depending on Nissan's recommendation. Manufacturers of AWD vehicles, for example, often recommend replacing all four tires at once because AWD systems need uniform tires to operate properly. Just replaced your tires and only one is damaged? You may not need to buy another new full set after all. If you can replace your damaged tire with the same type, brand, and size as the others, you may be able to save costs and only purchase one replacement. Need help? A tire technician can walk you through the options and help you determine what’s best for your vehicle’s performance and longevity.

Tire Inspection Services for Your Nissan D21

A flat tire is a surefire sign of tire damage, but other indicators of tire issues aren’t so easy to spot. Inconspicuous issues like bulging sidewalls, exhaust noise, leaks, or bent rims may indicate issues that need immediate attention. Stop tire damage in its tracks. Start with a tire inspection on your 1990 Nissan D21.
