Are you looking for What Size Tire For 15 x 8 Rim but don’t know where to start? If so, you’ve come to the right place.
This guide provides up-to-date information to help you choose the right tire size for a 15×8 rim. Let’s dive in!
What Size Tire Fits a 15×8 Rim?
The answer lies in understanding the compatibility between the rim and the tire. To ensure proper fitment, the tire and rim dimensions should match or complement each other closely.
First, let’s break down the dimensions of a 15×8 rim:
- 15 refers to the diameter of the rim in inches.
- 8 refers to the width of the rim in inches.
Knowing these measurements, we can identify the appropriate tire dimensions.
Tire Diameter
For a 15-inch rim, you’ll need a tire with a matching 15-inch diameter. This is non-negotiable—always confirm this measurement before choosing a tire.
Tire Width
Tire width is measured in millimeters. For an 8-inch rim width, the recommended tire width range is:
- 225–235 mm: Ideal for performance and fit.
- 215 mm: Slightly narrower but still acceptable.
- 245 mm: Slightly wider but may not perform as well as the recommended range.
You’ll find these measurements labeled on the tire. For example:
225/50R15 91H
- 225: Tire width in millimeters.
- 50: Aspect ratio (sidewall height as a percentage of the width).
- R: Radial construction.
- 15: Tire diameter in inches, matching the rim diameter.
This coding ensures you can confidently select the right tire for a 15×8 rim.

Speed Rating for a 15×8 Rim Tire
Once you’ve identified the correct size, it’s essential to check the tire’s speed rating to match your vehicle’s requirements. The speed rating indicates the maximum speed a tire can safely sustain.
In the example 225/50R15 91H, the H represents a speed rating of 130 mph. Ensure your vehicle’s maximum speed is below this limit for optimal performance and safety.
Load Index for a 15×8 Rim Tire
The load index indicates the maximum weight a tire can support at its maximum speed. For instance, in 225/50R15 91H, the 91 represents a load capacity of 1,356 lbs.
When choosing tires, ensure the load index exceeds the per-tire weight of your vehicle. Divide your vehicle’s total weight by four and confirm it’s below the tire’s load capacity for safe operation.
By understanding these measurements and ratings, you can confidently select the right tire for your 15×8 rims. Whether for street use, off-roading, or performance driving, this guide has you covered!
