Can I drive my Nissan on a flat tire?

Driving on a flat tire is not a good idea. Your D21 engine will keep running with a flat tire, but you could damage your wheel by continuing to drive on a flat.

Is temporary sealant bad for my Nissan's tires?

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.

What’s the harm in using my spare tire 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 1994 Nissan D21 is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Who repairs Nissan D21 tires?

Your local Firestone Complete Auto Care can carry out most Nissan D21 tire repairs, but the extent of the damage will determine if we are able to help.

Why do my D21 tires keep losing air?

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

Do all four tires on a Nissan D21 have to be replaced at the same time?

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.

Repairing Your Nissan D21 Tire

Cities are growing. New roads are being built, and old ones are getting a face lift. There's construction around every corner! That means more tire-damaging road debris and flat tires. If the road has been rough on your 1994 Nissan D21 tires, Firestone Complete Auto Care can help. 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 start by evaluating the state of wear, the location of damage, type of damage, and the size of the damage.

If we determine that your 1994 Nissan D21 tire can be safely repaired, we'll follow three basic steps to repair it: (1) Take the tire off the wheel for easy inspection, (2) fill the puncture to keep the moisture out, and (3) secure and seal the inner tire liner to ensure the tire is airtight.

Nissan D21 Tire Replacement

Unfortunately, some 1994 Nissan D21 tire damage can’t be effectively repaired. Tires with less than 2/32nd inch tread remaining can't be repaired, no matter how minor the damage. 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 puncture in the tire that is ¼ inch or greater in diameter; a puncture that lies outside the tire tread area; a tire with two or more punctures that are less than 16 inches away from each other; and a tire with tread separation or significant cuts.

When your damaged tire can’t be repaired, consult Nissan’s recommendations for replacing one, two, or all four of your tires. For vehicles with AWD, manufacturers recommend replacing all four tires simultaneously. This is because the AWD system can only function optimally when all tires are uniform. However, this may not be necessary if your remaining three tires are new. You might be able to replace one tire as long as it's the same brand, type, and size as the other three. Your tire technician can help you decide how many tires to replace and the kind of tire to purchase.

Do I Need a Tire Inspection for My Nissan D21?

Some tire issues can cause you to have a flat, but other damage isn't so noticeable right away. 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. Bring your 1994 Nissan D21 in for a tire inspection so we can assess the damage and help keep you safe on the road.
