235 mm (section width) | 9.252" (≈ 9.3") | 235 ÷ 25.4 = 9.252 |
105.75 mm (sidewall height) | 4.163" (≈ 4.2") | (235 × 0.45) ÷ 25.4 = 4.163 |
19 (rim diameter) | 19" | Given |
694.10 mm (overall diameter) | 27.327" (≈ 27.3") | (2 × 105.75 ÷ 25.4) + 19 = 27.327 |
2180.58456 mm (circumference) | 85.850" (≈ 85.8") | 27.327 × 3.1416 = 85.850 |
347.05 mm (radius) | 13.663" (≈ 13.7") | 27.327 ÷ 2 = 13.663 |
In inches, the 235/45R19 tire size can be represented as 27.3" × 9.3" R19.
Compare 235/45R19 with other tire sizes, such as 245/45R19 and 245/40R19, to understand the key differences and make the right choice when buying new tires.
The main difference between 235/45R19 and 245/45R19 is the tread width. The 235/45R19 tire is ≈ 0.4" or 10 mm narrower than the 245/45R19 tire, resulting in a ≈ 0.2" or ≈ 4.5 mm shorter sidewall height and ≈ 0.4" or ≈ 9 mm shorter overall diameter.

Yes, using a 245/45R19 tire size instead of a 235/45R19 is generally accepted, as the overall diameter difference is only 1.296% (≈ 1.3%), which is typically within the commonly recommended tolerance.
Expect slightly "slower” speedometer readings; When your dash shows 60 mph, you will actually be traveling 60.8 mph. The slightly taller sidewall of the 245/45R19 will provide a marginally softer ride and a bit more protection against potholes compared to the 235.
If you plan to switch to 245/45R19 instead of 235/45R19, well-regarded options in this size include:
The main difference between 235/45R19 and 245/40R19 is the balance of width and height. The 235/45R19 tire features a 7.75 mm (0.31") taller sidewall than the 245/40R19.
Because this height is added to both the top and bottom of the wheel, the 235/45R19 results in an overall diameter that is 15.5 mm (0.61") larger. This creates a 2.28% difference in height, which may cause a slight change in speedometer accuracy and ground clearance.

Yes, using a 245/40R19 tire instead of a 235/45R19 is technically acceptable. The overall diameter difference is 2.23%, which is within the industry-standard 3% tolerance. This swap provides a wider footprint for better grip but results in a slightly shorter tire. Drivers should be aware that this will cause the speedometer to read about 1.4 mph faster at highway speeds and will slightly increase the visible gap between the tire and the wheel well.
