What Size Spare Tire Cover Do I Need?

Choosing the correct spare tire cover size is essential for proper fit, appearance, and safety. A cover that’s too loose can fly off on the highway, while a too-tight cover won’t slip over the tire at all. This guide explains how to read tire sizes, which sizes fit the most popular vehicles, and how to choose the correct SpareCover® size every time.


Understanding Your Tire Size: The Only Number You Need to Know

Every tire has a printed size code that looks like this:

255/70R18265/75R16245/65R17

This single number tells you everything needed.

  • The first number is the width (mm)

  • The second is the sidewall ratio (%)

  • The last is the rim diameter (inches)


You do not need to measure the tire manually.Just enter this code into the SpareCover sizing tool and it automatically converts your tire into the correct cover size.


The Fastest and Easiest Way to Find Your Exact Spare Tire Cover Size

Finding your correct size takes less than 10 seconds:

  1. Look at the sidewall of your spare tire.

  2. Find the printed code (example: 255/70R18).

  3. Enter it into the SpareCover size tool.


The correct size appears instantly.This method works for Jeep, Ford Bronco, Toyota, Honda, Land Rover, Suzuki, Isuzu, and more.

  • Moisture buildup behind the cover


A properly sized SpareCover fits tight, smooth, and secure.
