Overall Diameter
The overall diameter refers to the total height of the tire. The 215/75r14 tire has a slightly larger diameter, measuring 26.7 inches (678.1mm), a 2.3% increase compared to the 26.11 inches (663.1mm) of the 205/75r14 tire. A larger diameter provides more ground clearance, beneficial for off-road driving or rough terrain navigation. However, it also results in a lower speedometer reading.

On the other hand, a smaller diameter like that of the 205/75r14 reduces ground clearance, potentially causing vehicle damage over obstacles or rough roads. Yet, it results in a higher speedometer reading.

Section Width
The section width, or tread width, measures the tire’s width. The 215/75r14 tire, with a width of 8.46 inches (215mm), is 4.9% wider than the 205/75r14 tire, which measures 8.07 inches (205mm). A wider tread improves traction due to a larger contact patch, benefiting acceleration, braking, and cornering.

However, it may produce more road noise due to the increased contact area. Conversely, a narrower tread like the 205/75r14 may offer reduced grip, particularly in wet or slippery conditions.

The 215/75r14 tire has a larger circumference of 83.87 inches (2130.31mm), a 2.3% increase over the 82.02 inches (2083.19mm) circumference of the 205/75r14. A larger circumference will result in lower speedometer readings, whereas a smaller circumference leads to higher speedometer readings.

Revolutions Per Mile

Revolutions per mile

The revolutions per mile refer to how many times a tire rotates over a mile. The 215/75r14 tire has fewer revolutions per mile (755.45) compared to the 205/75r14 (772.54), a decrease of 2.2%.

Fewer revolutions mean the tire covers more distance in each rotation, potentially reducing wear and tear and extending lifespan. However, a higher revolution rate could lead to faster wear due to increased friction with the road.

Sidewall Height
Sidewall height refers to the height of the tire’s sidewall. The 215/75r14 tire has a taller sidewall of 6.35 inches (161.25mm), 4.9% taller than the 205/75r14 tire with 6.05 inches (153.75mm).

A taller sidewall absorbs more road bumps, resulting in a smoother ride. It also increases traction on snowy or icy roads. Conversely, a smaller sidewall may lead to a harsher ride due to less cushioning but may provide a sportier appearance.

Rim Size
Both tires fit 14″ rims, but the recommended rim width range varies. The 205/75r14 tire fits a rim width range of 5.0-7.0 inches, while the 215/75r14 tire suits a slightly wider range of 5.5-7.0 inches. Larger rims can enhance a vehicle’s aggressive and sporty look, while smaller rims may provide a more classic appearance.

How much taller is a 205/75r14 tire than a 215/75r14?

The height of a 205/75r14 tire measures 26.11 inches (or 663.1 mm), while the height of a 215/75r14 tire measures 26.7 inches (or 678.1 mm). This means the 215/75r14 tire is approximately 0.59 inches (or 15 mm) taller than the 205/75r14 tire.

How much wider is a 205/75r14 tire than a 215/75r14?

Concerning the width, a 205/75r14 tire has a width of 8.07 inches (or 205 mm), while the width of a 215/75r14 tire is 8.46 inches (or 215 mm). Therefore, the 215/75r14 tire is roughly 0.39 inches (or 10 mm) wider than the 205/75r14 tire.

Can I use 205/75r14 instead of 215/75r14?

Regarding tire replacement, you have to consider that the overall diameter for a 205/75r14 tire is 26.11 inches (or 663.1 mm), and for a 215/75r14 it is 26.7 inches (or 678.1 mm). The difference between these diameters is about 0.59 inches or 15 mm, corresponding to about 2.3%.

As this difference is less than the generally recommended maximum of 3%, it should be possible to use a 205/75r14 tire in place of a 215/75r14. Nevertheless, it is always wise to consult a tire or vehicle expert before making such changes to ensure performance and safety.

Can I put a 205/75r14 on a 215/75r14?

With regards to rim compatibility, both the 205/75r14 and 215/75r14 tires can be fitted onto rims with widths within the ranges of 5.0-7.0 inches and 5.5-7.0 inches, respectively. Thus, it should be possible to mount a 205/75r14 tire onto a rim designed for a 215/75r14 tire.

Our Observation
The 215/75r14 tire is preferable for those seeking off-road performance, comfort, and an extended lifespan due to its increased diameter, width, and sidewall height. However, it may lead to lower speedometer readings and more road noise.

On the other hand, the 205/75r14 tire could be an ideal option for those prioritizing higher speedometer readings, reduced road noise, and a sportier look. But, it may result in a harsher ride and faster wear.

In conclusion, the decision between the 205/75r14 and the 215/75r14 largely depends on your driving conditions, vehicle capabilities, and personal preference. Always stay within the manufacturer’s recommended tire size range for optimal safety and performance.
