Overall Diameter
The overall diameter of a tire is the total height from the ground to the top of the tire. The 235/65r17 tire has a diameter of 29.03 inches (737.3mm), while the 225/65r17 tire has a diameter of 28.52 inches (724.3mm). This difference of 0.51 inches (13mm) or 1.8% may seem small, but it can significantly affect your vehicle’s performance.
A larger tire diameter provides more ground clearance, beneficial for off-road driving or navigating rough terrain. However, it can result in a lower speedometer reading. On the other hand, a smaller tire diameter reduces ground clearance, increasing the risk of scraping or damaging your vehicle on rough roads, but results in a higher speedometer reading.
Section Width
The section width of a tire refers to the width of the tire from one sidewall to the other. The 235/65r17 tire has a section width of 9.25 inches (235mm), while the 225/65r17 tire has a width of 8.86 inches (225mm). This difference of 0.39 inches (10mm) or 4.3% can affect the tire’s grip on the road.
A wider tread width generally improves traction due to a larger contact patch, especially during acceleration, braking, and cornering. However, wider tires often produce more road noise. Conversely, a narrower tread width reduces the surface area in contact with the road, potentially reducing grip, especially in wet or slippery conditions.
Circumference
The circumference of a tire is the distance around the tire. The 235/65r17 tire has a circumference of 91.19 inches (2316.3mm), while the 225/65r17 tire has a circumference of 89.58 inches (2275.46mm). This difference of 1.61 inches (40.84mm) or 1.8% can affect your speedometer reading.
An increased circumference will result in lower speedometer readings, while a decreased circumference will result in higher speedometer readings.
Sidewall Height
The sidewall height is the distance from the rim to the tread. The 235/65r17 tire has a sidewall height of 6.01 inches (152.75mm), while the 225/65r17 tire has a height of 5.76 inches (146.25mm). This difference of 0.26 inches (6.5mm) or 4.3% can affect your ride comfort and traction.
A taller sidewall acts as a buffer, absorbing more bumps and road irregularities for a smoother ride. It also increases traction on snowy or icy roads. Conversely, a shorter sidewall may lead to a harsher ride due to less cushioning but gives a sportier and more aggressive look.
Revolutions Per Mile
Revolutions per mile refers to how many times a tire will rotate in one mile. The 235/65r17 tire has 694.79 revolutions per mile, while the 225/65r17 tire has 707.26. This difference of 12.47 revolutions per mile or 1.8% can affect your tire’s lifespan.
A higher RPM typically means more wear, as the tire experiences increased friction with the road surface, leading to a shorter lifespan. Conversely, a lower RPM means the tire covers less distance in each rotation, potentially extending its lifespan.
Rim Size
Both tires fit on a 17″ rim. However, the 235/65r17 tire fits on a rim width range of 6.5-8.5″, while the 225/65r17 tire fits on a rim width range of 6.0-8.0″. Larger rims are often associated with a more aggressive and sporty look, while smaller rims can provide a more classic or conservative appearance.
How much taller is a 235/65r17 tire than a 225/65r17?
The height of a 235/65r17 tire is 29.03 inches (737.3 mm), whereas the height of a 225/65r17 tire is 28.52 inches (724.3 mm). As such, the 235/65r17 tire is roughly 0.51 inches (or 13 mm) taller than the 225/65r17 tire.
How much wider is a 235/65r17 tire than a 225/65r17?
Regarding width, the 235/65r17 tire measures 9.25 inches (235 mm), while the 225/65r17 tire is 8.86 inches (225 mm) wide. Consequently, the 235/65r17 tire is around 0.39 inches (or 10 mm) wider than the 225/65r17 tire.
Can I use 235/65r17 instead of 225/65r17?
The overall diameter of a 235/65r17 tire is 29.03 inches, while the 225/65r17 tire has an overall diameter of 28.52 inches. The difference between these two tire sizes amounts to 0.51 inches or roughly 1.8%. Since this is below the suggested 3% threshold, using a 235/65r17 tire instead of a 225/65r17 may be possible.
Can I put a 235/65r17 on a 225/65r17?
The 235/65r17 tire can fit on a rim width ranging between 6.5-8.5 inches, while the 225/65r17 tire can be mounted on a rim width from 6.0-8.0 inches. Therefore, if the current rim width falls within the compatibility range of both tires, it is technically feasible to mount a 235/65r17 tire on a rim designed for a 225/65r17.
Our Observation
Both 235/65r17 and 225/65r17 tires have their unique advantages and disadvantages. The choice between them depends on your driving conditions and personal preferences. If you prioritize ground clearance, traction, and a smoother ride, the 235/65r17 tire might be the better choice.
However, if you prefer a higher speedometer reading, less road noise, and a sportier look, the 225/65r17 tire could be the way to go. Remember, it is generally recommended to go with tires that have a diameter within 3% difference from the factory recommended tires. Always consult with a tire professional before making your final decision.
