How soon should I have my flat tire repaired?

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

Can I use an emergency/temporary sealant to fix my Mercury'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.

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 1989 Mercury Grand Marquis is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Who can repair Mercury Grand Marquis tires?

In most cases, your nearby Firestone Complete Auto Care can handle your Mercury Grand Marquis tire repair. Ultimately, the severity of the damage will determine if your tires can be repaired.

Why do my Grand Marquis tires keep losing air?

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

Do I have to replace all four Mercury Grand Marquis tires at the same time?

It's important to consider replacing your Grand Marquis tires in pairs or all four at once for safety and performance reasons, even if only two of them appear to be worn. If the remaining two tires are significantly newer, they may have different grip than the older tires, which can affect your vehicle’s handling. Always double-check your owner's manual since some vehicles require all four tires to be replaced if there's a tread difference of more than 3/32”.

Mercury Grand Marquis Tire Repair

Urban areas are booming. New roads and buildings are springing up. It seems construction is everywhere these days! Unfortunately, this can mean a higher chance of a flat or damaged tire caused by debris in the road. Firestone Complete Auto Care is here for you when your 1989 Mercury Grand Marquis 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. 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 1989 Mercury Grand Marquis tire is feasible and safe, we’ll get to work on the steps to fix it: (1) Separate the tire from the vehicle wheel, (2) fill the puncture to keep the moisture out, and (3) re-seal the inside lining of your tire so that air won’t escape.

Mercury Grand Marquis Tire Replacement

Not all 1989 Mercury Grand Marquis tire damage can be 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 puncture in the tire that is ¼ inch or greater in diameter; a tire with a puncture or damage outside the tread area; a tire with multiple punctures that are less than 16 inches apart; and a tire with cuts or tread separation.

Depending on what Mercury recommends for your car, you’ll want to consider purchasing one new tire, two new tires, or a new full set. 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. But, if you’ve recently replaced your tires and they don’t have significant wear, a new set might not be needed. 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.

Tire Inspection Services for Your Mercury Grand Marquis

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. Stop tire damage in its tracks. Start with a tire inspection on your 1989 Mercury Grand Marquis.
