Finding out the size of your spare tire is crucial for ensuring it fits your vehicle and is safe to use. Typically, you can find this information in your car’s owner’s manual, on the tire itself, or by checking the tire information placard located on the driver’s side door jamb.
How to Determine Your Spare Tire Size
Understanding how to determine your spare tire size can save you time and ensure safety. Here’s a step-by-step guide to finding this essential information:
1. Check the Owner’s Manual
The owner’s manual of your vehicle is the first place to look for the spare tire size. This document provides detailed information about all parts of your car, including the tires.
- Location: Usually found in the glove compartment.
- Information: Look for the section on tires or vehicle specifications.
2. Inspect the Spare Tire
If you can access the spare tire, inspect it directly. The tire’s sidewall will have a series of numbers and letters that indicate its size.
- Example: A marking like P195/65R15 indicates tire width, aspect ratio, and diameter.
- Tip: Make sure the tire is clean enough to read the markings.
3. Look at the Tire Information Placard
The tire information placard is typically located on the driver’s side door jamb. This placard provides critical information about tire sizes and recommended pressures.
- Details Included: Standard tire size, spare tire size, and recommended tire pressure.
- Location: Open the driver’s door and check the side of the door or the frame.
4. Use Online Resources
If you don’t have access to your manual or the tire itself, online resources can be helpful.
- Vehicle Manufacturer’s Website: Often provides detailed specifications.
- Tire Retailer Websites: Many offer a tool to find tire sizes based on vehicle make and model.
