BMW i3 Tires Size: Everything We Need to Know Before Buying New Tires

The BMW i3 is unlike almost every other car on the road. It looks futuristic, drives like a silent rocket through city streets, and comes wrapped in one of the most unusual tire setups we’ve ever seen on a production vehicle. At first glance, the tires almost look too skinny for the car. Yet that design was intentional from the very beginning.

If we’ve ever searched for “BMW i3 tires size,” chances are we quickly realized things can get confusing. Different wheel sizes, staggered fitments, winter packages, i3S differences, and limited tire options create a maze that many owners struggle to navigate.

The good news? Once we understand the logic behind BMW’s tire strategy, everything suddenly makes sense.

In this guide, we’ll break down BMW i3 tire sizes, wheel combinations, recommended replacements, winter setups, tire pressures, common mistakes, and how to choose the best tires for efficiency, comfort, and performance. Whether we own a standard i3 or the sportier i3S, this article will help us make smarter decisions and avoid expensive errors.

Why BMW i3 Tires Look So Different

The first thing most people notice about the BMW i3 is its unusually narrow tires. They resemble motorcycle tires more than traditional car tires. That wasn’t an accident.

BMW engineered the i3 around efficiency. Every component was designed to reduce drag and rolling resistance. Narrow tires create less friction with the road, which helps maximize electric range.

Think of the BMW i3 like a marathon runner wearing lightweight shoes instead of bulky hiking boots. The goal wasn’t brute grip. The goal was efficiency and agility.

The result?

• Better energy efficiency
• Lower rolling resistance
• Reduced aerodynamic drag
• Improved urban maneuverability
• Longer EV range

But there’s a tradeoff. Tire choices become far more limited than on conventional cars.

Understanding BMW i3 Tire Size Numbers

Before buying tires, we need to understand what the numbers actually mean.

A typical BMW i3 tire size may look like this:

155/70R19

Here’s the breakdown:

• 155 = Tire width in millimeters
• 70 = Sidewall height as a percentage of width
• R = Radial construction
• 19 = Wheel diameter in inches

The i3 uses extremely narrow widths compared to normal vehicles.

For perspective:

• A typical SUV tire may be 235 mm wide
• A BMW i3 tire can be as narrow as 155 mm

That’s a dramatic difference.

BMW i3 Factory Tire Sizes by Wheel Option

The BMW i3 came with several wheel configurations depending on trim level, production year, and whether we’re driving the i3 or i3S.

19-Inch Wheel Tire Sizes

Most standard BMW i3 models came equipped with 19-inch wheels.

Front Tire Size

• 155/70R19

Rear Tire Size

• 175/60R19

This staggered setup means rear tires are wider than the fronts.

20-Inch Wheel Tire Sizes

Some trims featured stylish 20-inch wheels for a more aggressive appearance.

Front

• 155/60R20

Rear

• 175/55R20

These tires look fantastic, but there’s a catch.

Low-profile 20-inch tires usually:

• Ride firmer
• Cost more
• Wear faster
• Increase pothole risk

If we drive mainly in rough urban environments, 19-inch wheels are often the smarter choice.

BMW i3S Tire Sizes

The i3S introduced a wider and sportier stance.

BMW i3S Front Tire Size

• 175/55R20

BMW i3S Rear Tire Size

• 195/50R20

The wider tires dramatically improve grip and cornering confidence.

The difference feels similar to switching from ballet shoes to athletic trainers. The i3S suddenly feels more planted during spirited driving.

The i3 is rear-wheel drive, and electric motors deliver instant torque. Wider rear tires help maintain grip during acceleration.

Benefits of staggered tires include:

• Better traction
• Improved handling balance
• More stable acceleration
• Enhanced cornering dynamics

However, staggered setups prevent front-to-rear tire rotation in many cases.

That means rear tires often wear faster.
