What happens if I drive my Mercury on a flat tire?

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.

Is temporary sealant bad for my Mercury'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?

For starters, your spare tire is designed to go short distances at low speeds. It’s not built to withstand the rough toll that the road can take from everyday driving! Putting off tire repair can also cause uneven tire wear in the long run – which could lead to a potentially costly toll on your steering and suspension system.

Who offers Mercury Grand Marquis tire repair?

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

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

Possible reasons for your Grand Marquis tires continuously losing air include a leaking valve steam, wheel damage, and a puncture or hole in the rubber.

Is it necessary to replace all four Mercury Grand Marquis tires at once?

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 are being built, and old ones are getting a face lift. Everywhere you look, it seems construction is in progress! Unfortunately, this can mean a higher chance of a flat or damaged tire caused by debris in the road. If the road has been rough on your 2004 Mercury Grand Marquis 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 your 2004 Mercury Grand Marquis tire puncture can be repaired, we'll follow three basic steps to repair it: (1) Remove the tire from the wheel for inspection and repair, (2) fill the puncture to keep the moisture out, and (3) secure and seal the inner tire liner to ensure the tire is airtight.

Mercury Grand Marquis Tire Replacement

Unfortunately, some 2004 Mercury Grand Marquis 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). This tread depth indicates that the tire is worn out, and needs to 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 puncture with a diameter bigger than ¼ inch; 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 major cuts or separated treads.

When your damaged tire can’t be repaired, consult Mercury’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. 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. Your tire technician can help you decide how many tires to replace and the kind of tire to purchase.

Tire Inspection Services for Your Mercury Grand Marquis

A flat tire? That’s pretty hard to ignore. But other tire damage? It’s not always obvious! 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 2004 Mercury Grand Marquis in for a tire inspection so we can assess the damage and help keep you safe on the road.
