How soon should I have my flat tire repaired?

Driving on a flat tire is not a good idea. Your Q45 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 Infiniti's tires?

Temporary sealants will solve your problem… for a little bit. If you’ve seen temporary or emergency tire sealant before (it usually comes in a can), it can be tempting to turn to this as a solution for your flat tire. Keep in mind that these fixes could buy you some time to get to Firestone Complete Auto Care for a proper repair, but they could also cause some harm in the process (for example, damage to your TPMS). Plus, using a product like this could void your tire warranty.

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.

Where can I get my Infiniti Q45 tires repaired?

Your local Firestone Complete Auto Care can carry out most Infiniti Q45 tire repairs, but the extent of the damage will determine if we are able to help.

Why do the tires on my Q45 keep losing air?

Possible reasons for your Q45 tires continuously losing air include a leaking valve steam, wheel damage, and a puncture or hole in the rubber.

Do all four tires on a Infiniti Q45 have to be replaced at the same time?

It's important to consider replacing your Q45 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”.

Repairing Your Infiniti Q45 Tire

City populations are exploding. New roads and buildings are springing up. It seems construction is everywhere these days! New progress is exciting, but the road debris it leaves behind may mean trouble for your tires. If your 1991 Infiniti Q45 is in need of a tire inspection or possible flat tire repair, Firestone Complete Auto Care has your back. Our tire technicians can determine whether it's safe to plug and patch the tire, or whether it needs to be replaced. We'll start by evaluating the state of wear, the location of damage, type of damage, and the size of the damage.

If a repair on your 1991 Infiniti Q45 tire is feasible and safe, we’ll get to work on the steps to fix it: (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.

When Is It Time for Infiniti Q45 Tire Replacement?

Unfortunately, some 1991 Infiniti Q45 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. 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 puncture in the tire sidewall (or anywhere else that’s not within the tread area); a tire with two or more punctures that are less than 16 inches away from each other; 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 Infiniti's recommendation. 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. 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. 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 Infiniti Q45

Some tire issues can cause you to have a flat, but other damage isn't so noticeable right away. Inconspicuous issues like bulging sidewalls, exhaust noise, leaks, or bent rims may indicate issues that need immediate attention. Stay ahead of potentially dangerous tire issues. Bring your 1991 Infiniti Q45 in for a tire inspection.
