Tire Size 205/60r15 vs 195/65r15
The main difference between tire sizes 205/60r15 and 195/65r15 is in their width and sidewall height. The 205/60r15 is wider by 0.39 inches (10 mm), offering a potentially larger contact patch with the road, which could improve grip. However, its sidewall height is slightly lower by 0.15 inches (3.75 mm), which might result in a firmer ride compared to the 195/65r15 due to less cushioning.

Overall Diameter
The 195/65R15 tire has an overall diameter of 24.98 inches (634.5 mm), whereas the 205/60R15’s diameter is slightly smaller at 24.69 inches (627 mm), marking a 1.2% difference. A larger diameter provides more ground clearance, beneficial for off-road driving or rough terrain. It also results in a lower speedometer reading.
Conversely, a smaller diameter decreases ground clearance, increasing the risk of scraping or damage, particularly over obstacles or rough roads, resulting in a higher speedometer reading.
Section Width
The section width for the 195/65R15 is 7.68 inches (195 mm), and for the 205/60R15, it is 8.07 inches (205 mm), a 5.1% increase. A wider tread width typically improves traction due to the larger contact patch, improving grip during acceleration, braking, and cornering.
However, it may also generate more road noise. Conversely, the narrower tread width reduces the surface area in contact with the road, which might reduce the tire’s grip, especially in wet or slippery conditions.
Circumference
The 195/65R15 has a circumference of 78.48 inches (1993.34 mm), while the 205/60R15 has a slightly smaller circumference of 77.55 inches (1969.78 mm), marking a 1.2% difference. A larger circumference will result in lower speedometer readings, while a decreased circumference will result in higher readings.
Revolutions Per Mile
The 195/65R15 tire spins 807.36 revolutions per mile (501.67 per km), while the 205/60R15 spins a bit more at 817.02 revolutions per mile (507.67 per km), a 1.2% increase.
Higher RPM usually means more wear due to increased friction with the road, potentially leading to a shorter lifespan. In contrast, fewer revolutions per mile indicate the tire covers less distance per rotation, potentially extending its lifespan.
Sidewall Height
Sidewall height for the 195/65R15 is 4.99 inches (126.75 mm), compared to the 205/60R15’s 4.84 inches (123 mm), a 3% decrease. Taller sidewalls act as a buffer, absorbing more bumps and road irregularities for a smoother ride.
They also increase traction on snowy or icy roads. Conversely, smaller sidewalls may have a harsher ride due to reduced cushioning but can give a sportier look.
Rim Size
The rim size for both tire sizes is 15 inches, with a rim width range of 5.5-7.0 inches. While rim size doesn’t differ in this case, it’s worth noting that larger rims usually provide a more aggressive and sporty look, while smaller rims lend a more classic or conservative appearance.
How much taller is a 195/65r15 tire than a 205/60r15?
Comparing the heights of the two tires, the 195/65r15 tire measures 24.98 inches (or 634.5 mm), while the 205/60r15 tire is slightly shorter at 24.69 inches (or 627 mm). This means the 195/65r15 tire is approximately 0.3 inches (or 7.5 mm) taller than the 205/60r15 tire.
How much wider is a 195/65r15 tire than a 205/60r15?
In terms of width, the 195/65r15 tire has a width of 7.68 inches (or 195 mm). On the other hand, the 205/60r15 tire is wider, measuring 8.07 inches (or 205 mm). Therefore, the 205/60r15 tire is around 0.39 inches (or 10 mm) wider than the 195/65r15 tire.
Can I use 195/65r15 instead of 205/60r15?
Looking at the overall diameter, the 195/65r15 tire has an overall diameter of 24.98 inches (or 634.5 mm), whereas the 205/60r15 tire has an overall diameter of 24.69 inches (or 627 mm).
The difference in diameter between these two tires is about 0.3 inches (or 7.5 mm), representing a decrease of approximately 1.2%. This is less than the 3% difference typically advised against when replacing tires, so using a 195/65r15 tire instead of a 205/60r15 tire might be possible.
Can I put a 195/65r15 on a 205/60r15?
The 195/65r15 and 205/60r15 tires both have a rim width range of 5.5-7.0 inches. This indicates that these tires could be mounted interchangeably on the same rims, as their required rim widths overlap.
Our Observation
Both 195/65R15 and 205/60R15 tires offer unique advantages. The 195/65R15, with its larger diameter, taller sidewall, and less revolutions per mile, offers better ride comfort, more ground clearance, and potentially longer lifespan.
On the other hand, the 205/60R15, with its wider section width and slightly more revolutions per mile, might provide better traction and a sportier feel, although with potentially higher wear.
In choosing between these sizes, one must consider their driving style, the terrain they often encounter, and their comfort and aesthetic preferences. Remember, always consult with a tire expert before making a final decision.
