235/40R19 tires have a section width of 235 millimeters (mm), an aspect ratio of 40%, radial construction, and a 19-inch wheel diameter. Before buying tires sized 235/40R19, converting 235/40R19 size in inches, comparing it with similar tire sizes like 235/45R18 and 225/40R19, and researching the best 235/40R19 tires helps drivers shop for the right set for their vehicles.
What Are the Dimensions of a 235/40R19 Tire in Inches?
235/40R19 tires have a section width of 9.252" (≈ 9.3"), a sidewall height of 3.701" (≈ 3.7"), and a wheel diameter of 19 inches. The overall tire diameter of a 235/40R19 tire is 26.402" (≈ 26.4"), the circumference is 82.944" (≈ 82.9"), and the recommended rim width range is 8.0 to 9.5 inches.
In inches, the 235/40R19 tire size can be represented as 26.4" × 9.3" R19 (26.4" tall by 9.3" wide) and is designed to fit 19-inch wheels.
With a total circumference of 82.9", the 235/40R19 size provides a low-profile look and sharp handling characteristics for modern sedans and coupes.
235/40R19 tire size in millimeters and inches are presented in the below table:
235/40R19 Tire Size Dimensions | 235/40R19 Tire Size Dimensions in Inches (") | Formula to Convert 235/40R19 Size in Inches (") |
235 mm (section width) | 9.252" (≈ 9.3") | 235 ÷ 25.4 = 9.252 |
94.00 mm (sidewall height) | 3.701" (≈ 3.7") | (235 × 0.40) ÷ 25.4 = 3.701 |

335.30 mm (radius) | 13.201" (≈ 13.2") | 26.402 ÷ 2 = 13.201 |
Is 235-40R19 a Low Profile Tire?
Yes, the 235/40R19 is considered a low-profile tire. The 235/40R19 tire has an aspect ratio of 40, which is typically categorized as "low profile." Tires with a 40-series profile are designed for improved lateral stability and sharper steering response, common on sports sedans and performance vehicles.
What Cars Use 235-40-19 tires?
The 235/40R19 tires are typically found on higher trim levels of mid-size sedans and sport-oriented luxury vehicles. Common vehicles using 235/40R19 tires include Honda: Accord (Sport, Touring, and Sport Special Edition trims), Toyota: Camry (XSE trim) and Avalon, Tesla: Model 3 (Standard with 19" Sport Wheels), Volkswagen: Passat, Beetle, and Arteon, Volvo: S60 and V60, Skoda: Superb and Karoq, Kia: K5 and Optima, Ford: Fusion (Titanium trims), Lexus: ES, GS, and RC series, and Audi: Q2 and RS4 (older generations).
Car manufacturers choose 235/40R19 for these models because it provides a sportier look and sharper handling without needing the extreme width of a high-performance sports car tire.

Well-regarded options in 235/40R19 size include:
What Should Tire Pressure Be For 235-40R19 Tires?
For vehicles using 235/40R19 tires, the recommended tire pressure typically falls between 32 and 35 PSI, though some performance or heavy-load setups may require up to 38 PSI.
Because this is a low-profile tire with less air volume to cushion the rim, maintain the pressure as recommended by the manufacturer (which you can find on the door jamb) to prevent wheel damage from potholes.
Comparison of 235/40R19 With Similar Tire Sizes
Compare 235/40R19 with other tire sizes, such as 235/45R18 and 225/40R19, to learn the key differences between them and make the right choice when buying new tires.
What Is the Difference Between 235/40R19 vs 235/45R18?
The main difference between 235/40R19 and 235/45R18 lies in the sidewall height and wheel diameter. The 235/40R19 tire has an 11.75 mm (approx. 0.46") shorter sidewall than the 235/45R18. However, because the 235/40R19 tire is mounted on a rim that is 1.00" (25.40 mm) larger in diameter than the 235/45R18, the 235/40R19 results in an overall diameter that is only 1.90 mm (approx. 0.07") taller. This minimal variance ensures that both sizes maintain nearly identical ride heights and speedometer accuracy.

Can I use 235/45R18 instead of 235/40R19?
No, you can’t use a 235/45R18 size instead of a 235/40R19 size without changing your wheels, due to the different wheel size (18’’ vs 19’’). The overall diameter difference between the two sizes is small, about 0.284% (≈ 0.3%), so if you also change wheels to 18", the rolling diameter/speedometer impact is typically minimal, and the swap is considered safe.
What Is the Difference Between 235/40R19 vs 225/40R19?
The main difference between 235/40R19 and 225/40R19 is the section width. The 235/40R19 tire is 10 mm (approx. 0.39") wider than the 225/40R19. Because the aspect ratio (40) is a percentage of that width, the 235/40R19 also has a 4.00 mm (0.16") taller sidewall, resulting in an overall diameter that is 8.00 mm (0.31") larger than the 225/40R19.
