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 2025 BMW 840i Gran Coupe is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Repairing Your BMW 840i Gran Coupe Tire

Cities are growing. New roads and buildings are springing up. 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 2025 BMW 840i Gran Coupe tires, Firestone Complete Auto Care can help. Our tire technicians can determine whether it's safe to plug and patch the tire, or whether it needs to be replaced. 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 your 2025 BMW 840i Gran Coupe tire puncture can be repaired, we’ll get to work on the steps to fix it: (1) Separate the tire from the vehicle wheel, (2) fill in the area that’s been punctured to prevent damage from moisture, and (3) re-seal the inside lining of your tire so that air won’t escape.

BMW 840i Gran Coupe Tire Replacement

Sometimes, 2025 BMW 840i Gran Coupe tire damage calls for more than a repair. Tires with less than 2/32nd inch tread remaining can't be repaired, no matter how minor the damage. 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 puncture in the tire that is ¼ inch or greater in diameter; a puncture that lies outside the tire tread area; multiple punctures that are too close together (less than 16 inches between them); 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 BMW'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. Just replaced your tires and only one is damaged? You may not need to buy another new full set after all. 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.
