- The 2019 Chevrolet Bolt EV uses 38 PSI cold on the front axle and 36 PSI cold on the rear axle. These are the OEM specifications. Always measure tire pressure when the tires are cold — before driving or after sitting for at least 3 hours.
- What tire size does the 2019 Chevrolet Bolt EV use?
- The standard (base trim) tire size for the 2019 Chevrolet Bolt EV is 215/50R17. Higher trim levels and optional packages may use a different size — check the sticker inside your driver's door for the exact specification for your vehicle.
- How do I convert the 2019 Chevrolet Bolt EV tire pressure to bar?
- 38 PSI = 2.6 bar (front) and 36 PSI = 2.5 bar (rear). In kPa: 262 kPa front and 248 kPa rear. Multiply PSI × 0.0689 to convert to bar.
- Why are the front and rear tire pressures different on the 2019 Chevrolet Bolt EV?
- The 2019 Chevrolet Bolt EV uses 38 PSI front and 36 PSI rear because the two axles carry different loads. The front axle carries roughly 60% of the vehicle's 1616 kg curb weight, requiring a slightly different pressure to maintain the correct contact patch at each corner.
- What happens if the 2019 Chevrolet Bolt EV tires are underinflated?
- Running 5+ PSI low on the Chevrolet Bolt EV causes uneven shoulder wear, increased rolling resistance (worse fuel economy), higher tire operating temperature, and reduced wet braking performance. In extreme cases, chronic underinflation can cause sidewall failure. Check pressure monthly and always after a large temperature swing.
- What do the numbers in 215/50R17 mean on the 2019 Chevrolet Bolt EV?
- On the 2019 Chevrolet Bolt EV, 215/50R17 breaks down as: 215 = section width in millimetres (8.46"), 50 = aspect ratio (the sidewall is 50% of the width, so 107.5 mm / 4.23" tall), R = radial construction, and 17 = the wheel diameter in inches.
- What is the overall diameter of the 2019 Chevrolet Bolt EV tires?
- The 215/50R17 tire on the 2019 Chevrolet Bolt EV has an overall diameter of about 25.46" (647 mm) and a rolling circumference of roughly 80", giving about 792 revolutions per mile. Fitting a tire with a different diameter will throw off your speedometer and odometer.
