Where is DOT Code on Tire? Complete Location Guide

Finding the DOT code on your tire can be tricky. This guide shows you exactly where to look and what to do if you can't find it.

Quick Answer: Where to Find DOT Code

📍 Location:

The DOT code is stamped on the sidewall of your tire. It may be on the outer sidewall (visible from outside) or the inner sidewall (facing the vehicle). Some tires have it on both sides.

Step-by-Step Guide to Finding DOT Code

Step 1: Check the Outer Sidewall

Start by looking at the outer sidewall of your tire (the side facing outward). The DOT code is usually located near the rim, close to where the tire meets the wheel.

  • Look for text starting with "DOT"
  • Followed by letters and numbers
  • Ending with 4 digits (production date)

Step 2: Check the Inner Sidewall

If you don't see the DOT code on the outer sidewall, it might be on the inner sidewall (the side facing your vehicle). You may need to:

  • Turn your steering wheel to get better visibility
  • Use a flashlight or phone light
  • Get down at tire level to see the inner sidewall

Step 3: Look for Different Formats

DOT codes can appear in different formats:

DOT ABCD 4523
DOT ABCD EF 4523
ABCD 4523 (without DOT prefix)

Why DOT Code Location Varies

Tire manufacturers place DOT codes in different locations for various reasons:

Manufacturer Preference

Different tire brands have different placement policies. Some prefer the outer sidewall for visibility, while others use the inner sidewall.

Tire Design

Some tire designs have more decorative sidewalls, which may push the DOT code to a less visible location.

Regulatory Requirements

DOT regulations require the code to be on at least one sidewall, but not necessarily both.

Space Constraints

Smaller tires or tires with extensive branding may have limited space for the DOT code.

What to Do If You Can't Find DOT Code

🔍 Troubleshooting Tips:

  • Clean the tire sidewall - dirt and grime can obscure the code
  • Use proper lighting - a flashlight helps significantly
  • Check both front and rear tires
  • Look at different angles - sometimes the code is only visible from certain viewpoints
  • Check all four tires - codes may be in different locations

Frequently Asked Questions

Is the DOT code always visible from outside?

No, not always. Many tires have the DOT code only on the inner sidewall. This is perfectly normal and legal. If you can't find it on the outer sidewall, check the inner sidewall.

Can I find the DOT code without removing the tire?

Yes, in most cases. You can usually see at least part of the inner sidewall by turning your steering wheel or using a mirror. However, for better visibility, you may need to move the vehicle or remove the tire.

Do all tires have DOT codes?

All tires sold in the United States are required to have DOT codes. If your tire doesn't have a visible DOT code, it may be worn away, covered, or the tire may be non-compliant.
