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

Driving on a flat or underinflated tire can put extra stress on your wheels and alignment. While it’s sometimes necessary to drive a short distance on a flat tire to get to a safe place, don’t take any other trips in your 740iL until you can have the flat tire repaired or replaced.

Will a temporary sealant fix my BMW's flat tire?

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.

How long can I drive my BMW on a spare tire?

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 1998 BMW 740iL is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Who offers BMW 740iL tire repair?

Your local Firestone Complete Auto Care can carry out most BMW 740iL tire repairs, but the extent of the damage will determine if we are able to help.

What can cause 740iL tires to keep losing air?

Your 740iL tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

Do all four tires on a BMW 740iL have to be replaced at the same time?

It's important to consider replacing your 740iL 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 BMW 740iL Tire

Cities are growing. New roads and buildings are springing up. There's construction around every corner! Unfortunately, this can mean a higher chance of a flat or damaged tire caused by debris in the road. If your 1998 BMW 740iL is in need of a tire inspection or possible flat tire repair, Firestone Complete Auto Care has your back. In some cases, a tire doesn’t have to be replaced – it can be plugged and patched with a simple repair. Depending on the damage, though, a repair might not be the right move. Our technicians can determine which option is best for your situation. We’ll begin by taking a look at where the damage is, the type and extent of the tire damage, and how all of your tires are wearing.

If your 1998 BMW 740iL tire puncture can be repaired, 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 BMW 740iL Tire Replacement?

Not all 1998 BMW 740iL tire damage can be repaired. 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. At this tread depth, the tire is worn out and must be replaced. Other tire damage that can't be safely repaired includes 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); multiple punctures that are too close together (less than 16 inches between them); and a tire with tread separation or significant cuts.

Depending on what BMW 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. 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.

Do I Need a Tire Inspection for My BMW 740iL?

Some tire issues can cause you to have a flat, but other damage isn't so noticeable right away. Bent tire rims, bulging tire sidewalls, leaks under your car, or noise from your exhaust system can all point to tire-related damage that should be addressed quickly. Stop tire damage in its tracks. Start with a tire inspection on your 1998 BMW 740iL.
