Tire Sizes

When shopping for tires, the size of the tire is key. Two popular tire sizes are 315 70 R17 and 35 12.5 R17. The 315 70 R17 has a width of 315 millimeters, an aspect ratio of 70, and a rim diameter of 17 inches. The 35 12.5 R17 has a width of 350 millimeters, an aspect ratio of 12.5, and a rim diameter of 17 inches as well.

Rim Diameter

The rim diameter for both the 315 70 R17 and 35 12.5 R17 is 17 inches. This means that both tires can be fitted to rims with 17 inch diameters, allowing them to be used on many different types of vehicles.

Tread Width

The tread width for the 315 70 R17 is 315 millimeters while the tread width for the 35 12.5 R17 is 350 millimeters. This means that the 315 70 R17 is slightly more narrow than the 35 12.5 R17 and will allow for improved handling in certain conditions such as wet or icy roads due to its smaller contact patch with the road surface.

Aspect Ratio

The aspect ratio for the 315 70 R17 is 70 while the aspect ratio for the 35 12.5 R17 is 12.5 . The aspect ratio indicates how tall or short a tire’s sidewall is in relation to its width; in this case, the 315 70 R17 has a taller sidewall than the 35 12.5 R17 which will result in better ride quality due to increased cushioning from road bumps and other irregularities in driving surfaces.

Circumference

The circumference of a tire affects how quickly it accelerates and how it handles turns; this measurement is also important when it comes to selecting tires as some vehicles require specific measurements to function properly with certain tires installed on them.. The circumference of the 315 70 R17 is 1002.756 millimeters while that of the 35 12.5 R17 is 1155.147 millimeters; this means that despite their similar sizes, there are slight differences between them when it comes to their circumferences which could affect their performance depending on what type of vehicle they are being used on and what type of driving conditions they will be subjected to regularly..

Load Index

The Load Index for 315 70 R17 is 126, which is a high load rating for a tire of this size. This means it can safely handle heavier loads than other tires in this size range. The Load Index for 35 12.5 R17 is 108, which is still considered a moderate load rating. This tire can handle lighter loads than the 315 70 R17, but still provide good performance and dependability.

Speed Rating

The Speed Rating for 315 70 R17 is 115S/113S, indicating that the tire has been tested and certified to meet or exceed speed standards set by the manufacturer. This rating allows drivers to feel confident that their tire will be able to handle higher speeds without compromising safety and handling. The Speed Rating for 35 12.5 R17 is 113S, which means that it can also handle higher speeds without compromising safety and handling, though not as much as the 315 70 R17.

Tire Construction

Both tires feature radial construction, meaning that they have strong sidewalls and more uniform tread wear than bias-ply tires of similar sizes. Radial construction also offers better fuel efficiency and improved ride comfort than traditional bias-ply tires, allowing drivers to enjoy the benefits of a smoother ride with less resistance from the road surface.

Performance Traits

The 315 70 R17 has an aggressive sidewall styling that provides great off-road performance when tackling challenging terrain or traversing difficult roads. It also offers superior traction on all surfaces due to its advanced tread design, allowing drivers to experience maximum grip in any situation. The 35 12.5 R17 has an all-purpose tread pattern that provides rugged terrain performance as well as good everyday driving characteristics on standard roads or highways. With its strong construction and reliable performance traits, both of these tires are sure to provide drivers with confidence on the road no matter what their destination may be.
