Why Do Tesla Tires Have Foam in Them? Benefits Explained

Teslas have excessive weight because of the large amount batteries in their packs. This caused a few headaches for the company because the tires wore out quickly and caused unnecessary road-cabin noise. Many tire companies helped and partly solved this problem by engineering tires suited for Teslas. But adding foam does also have a few benefits.

Foam-filled tires may reduce tire cavity noise by up to 9 dB. It prevents vibration from being transferred from the tire to the wheel, axle, and, eventually the cabin. They can also provide a smoother ride, save you money, may never go flat, and can use any tire brand that fits the wheel.

To see a detailed explanation of this topic, check out the rest of the article. It does come with a few interesting caveats.

Foam in Tesla Tires

The foam that fills Tesla tires is a urethane liquid that cures into a solid state within twenty-four hours. The foam functions to maintain constant pressure and remove the possibility of experiencing a flat tire. 

The foam removes the possibility of having a flat tire while the pneumatic tire gives a smooth ride. Foam-filled Tesla tires will last as long as the casing holding the foam lasts.

Benefits of Foam-Filled Tesla Tires

The two options for solid tires are foam-filled or solid pneumatic tires. The benefits of foam-filled Tesla tires are clear. These tires offer: 

  • A smoother ride.
  • Versatility since you can fill any tire with foam.
  • Less cost than solid tires, especially when rubber costs are high.
  • A quieter ride due to less road noise.
  • Never goes flat.
  • Can use any tire brand that fits the wheel.

Here is a YouTube video on the foam inside a Tesla tire. 

Why Tesla Puts Foam in Their Tires

Tesla lines their tires with foam because the company is known for being a cutting-edge manufacturer of elevated electric cars. While Tesla did not invent urethane foam, they used the technology for their car tires. Elon Musk called it “internal acoustic foam” to improve tire noise.

While the construction industry uses foam-filled tires to reduce the chance of flat tires, Tesla adapted the foam to minimize cabin noise with foam-filled tires. You might think the electric car would make little to no noise in the absence of an engine, but the tires create noise that reverberates inside the vehicle. 

Cabin noise has been the leading complaint of Tesla owners, and this is Tesla’s solution for quieter cabins. 

Noise Reduction

Many people think that because Teslas are electric vehicles, they are very quiet. The average sound in a Tesla is still low compared to gas-powered cars, soft enough to have a normal conversation without raising your voice. This is generally in the 60-70 decibels range. 

The foam-filled tires reduce the noise inside the cabin by almost 9 decibels, an important measurement.

They Burn Out Faster than Regular Tires

Tesla and other electric vehicle tires do not last longer than conventional tires. Some tire shops report changing the tires on electric vehicles up to 10,000 miles (16093 km) sooner than conventional tires due to the immediate torque on takeoff and excessive weight of the batteries. 

I also wrote a useful article dedicated to this topic called: “How Long Do Tesla Tires Last?” This serves as a guide. Check it out!

When a Tesla takes off from a stop, the power at acceleration can make the tire treads wear down faster. It is like a mini-burnout that removes a layer of the surface from the tires.

Using Tires Other Than Tesla Official 

You don’t have to use Tesla-manufactured tires. Many EV owners want a quiet, comfortable ride on tires that offer sustainability and safety but don’t want the Tesla tire price tag.

In fact, check out this this related article that I wrote about the Best Tesla Model 3 Replacement Tires. It will provide some further insight.

Companies like Nokia and Michelin manufacture premium tires targeting the electric car niche. These tires offer innovative tire solutions to meet the year-round weather-related needs of Tesla owners. Whether you deal with heavy snow in winter or hot streets in summer, their state-of-the-art tires come in studded and non-studded models. 

Another consideration for Tesla owners is low rolling resistance to decrease the environmental impact. Most EV tires allow you to travel further with a smaller footprint. 

You can Use Any Tire Brand on a Tesla

Technically, you can use any tire brand on a Tesla as long as the tire fits the wheel. Teslas usually require eighteen or nineteen-inch (45.72 or 48.26 cm) tires. 

This means that your tire service can fill any size tire with urethane foam, and it will work well and never run flat. After they inject the foam, the tires must lay on a flat surface for twenty-four hours. The foam will be rigid, and the tires will be ready to mount on the car.

Tesla Tire Rotation and Service Recommendations

You might be confused and think Tesla tires need special care and service. This chart will help you understand the service requirements for your tires and anticipate replacements.

Tesla Model Tire RotationAlignmentReplacement 
Model 3Every 6,250 miles (10,000 km)If tire wear is unevenWhen tread has worn down to 4/32” (3mm)
Model XEvery 6,250 miles (10,000 km)
Side to side for front and back tires.
When noticeable vibration in the steering yokeWhen tread has worn down to 3/32” (2mm)
Model SEvery 5,000 miles (8,000 km)Annually Around 30,000 miles
Model YEvery 5,000 miles (8,000 km)Annually When tread has worn down to 2/42” (1.5 mm)
While the chart above indicates when to rotate, align, balance, and replace Tesla tires, many Tesla owners report a practical lifespan of almost 10,000 miles (16093 km) longer than the Tesla manual says to perform this tire maintenance.

I would recommend having the tires checked at your service center starting around 15,000 miles (24,140km). Some models are hard on the tires when you start quickly from a stop, causing the rear tires to wear faster.

Frequently Asked Questions

Do I Have To Change All the Tires on a Tesla at One Time?

Tesla recommends replacing tires in pairs. You need to replace either both front or rear tires, especially when your Tesla has a staggered tire setup.

Can Tesla Tires Be Filled With Air Instead of Foam?

You can put air in Tesla tires. Check inside the front door to find the correct PSI (pressure per square inch) and fill your tires to that number. You can use the air compressor at any gas station.
