Usually, we never notice the numbers written on the tires but these numbers are having a bulk of information in them. Let’s read the article further for more information about tire sizes.
Types of Tire Size Measurement
There are two types of tire measurement sizes.
Somehow, it is quite difficult to understand this measurement. Let’s try to understand it by starting it with Metric.
There are five sections of Metric sizing.
First, one or two alphabets in tires stand for different categories of tires.
LT: Light Truck, P: Passenger car tires, ST: Special Trailer, T: Temporary car tires.
Section width is about the measurement of the tire in millimeters from sidewall to sidewall.
The aspect ratio of a tire is about the height of a tire’s sidewall as a percentage of the width of the tire.
A radial ply is a particular design of vehicle tires in which cord plies are arranged at 90 degrees to the direction of travel.
The wheel size is the size assignment of a wheel given by its distance across, width, and balance.
Flotation tire sizing is much easier than Metric. In this sizing criteria, tires are measured by inches instead of millimeters. Mostly both tire sizes are equivalent and only the method of measurement is different.
Here, we have read about the sizing techniques, and now is the time to understand the different tire sizes fitting on different rims according to the needs. For this purpose, we need to understand rim diameters.
What Is Rim Diameter?
The diameter of the wheel is about the distance between the tire and tube surface on which tire beads are set. These are classified into certain categories.
Overall Tire Diameter:
SW: Section width, AR: Aspect Ratio, RD: Rim diameter, SH: Section height, CI: Tire circumference, RE: Revolutions per mile/km.
What Size Does Tire Fit a 15×8 Rim?
Tire size depends on the size of the rim. When the diameter of the rim is 15 and the width is 8 the best tire size is 33×12.5. Its sidewall is 8 inches that are equal to the width of the rim. It is even connected from the bead to the thread. This size has great protection overall for the rim.

Guide to Choose the Right Tire Size for the Rim
For getting the best tire for your rim of different sizes you need to measure the rim and tire sizes. You can see the 3 digital numbers on the tire followed by 2 digital numbers also flowed by the letter “R” OR “ZR” again followed by two digital numbers which are the same size as a tire. You can start this task with a measurement of the width of the tire. Also, measure the rim not from the edges but from the point of beads. You also can take help from the tire size calculator for the selection of an appropriate tire.
