Aspect Ratio
The aspect ratio is the height of the Tire’s sidewall expressed as a percentage of the width. In other words, it is the height of the Tire from the bead to the top of the tread divided by the width of the Tire.

The aspect ratio of a 305 70r18 tire is 70%. This means that the height of the sidewall is 70% of the width of the Tire, which is 213.5 millimeters. The aspect ratio of a 295 70r18 tire is also 70% which is 206.5 millimeters. As you can see, the only difference between these two sizes is the width of the Tire 7 millimeters.

Construction Type
Both 305 70r18 and 295 70r18 tires are radial tires. Radial tires are the most common type of tire on the market today. They are made with steel belts that run around the circumference of the Tire. The tread and sidewalls are then attached to the belts.

Sidewall Height
The sidewall height is the distance between the rim and the outer edge of the tire. The 305/70r18 has a taller sidewall height of 8.41 inches compared to 8.13 inches for the 295/70r18. This taller sidewall can provide better cushioning and absorb impact, which can result in a smoother ride.

Rim Size
The last number in a tire size is the diameter of the wheel that the Tire can be mounted on. Both 305 70r18 and 295 70r18 tires can be mounted on 18-inch wheels. If you have a set of 18-inch wheels and you are trying to decide between these two sizes, it comes down to personal preference.

Circumference
The circumference of a tire is the distance around the outer edge of the tire. The 305/70r18 has a larger circumference of 109.1 inches compared to 107.9 inches for the 295/70r18. This larger circumference can result in a slight decrease in acceleration, but it can also improve fuel economy and provide a smoother ride.

Revolutions Per Mile
The number of revolutions per mile is the number of times a tire rotates to travel one mile. The 305/70r18 has a lower revolutions per mile of 579.36 compared to 588.68 for the 295/70r18. This means that the 305/70r18 will rotate fewer times to cover the same distance, which can result in improved fuel economy.
