Tire Size Chart: Complete Guide for Drivers & Enthusiasts
Last updated on August 7th, 2026
A tire size chart helps you compare tire dimensions, identify compatible replacement sizes, and understand how different tire sizes relate to one another. Whether you’re replacing worn tires, checking fitment, or comparing metric and flotation sizes, the right chart makes the process faster and more accurate.
This guide explains how tire size charts work, how to use them correctly, and includes wheel-size and overall diameter charts to help you compare common tire sizes with confidence. You’ll also learn when it’s safe to change tire sizes and the key factors to check before making a replacement.
What Is a Tire Size Chart?
A tire size chart is a reference guide that helps you compare tire dimensions, identify compatible replacement sizes, and understand how different tire sizes relate to one another. Instead of calculating measurements manually, you can quickly compare tire width, sidewall height, overall diameter, and wheel size to find sizes that are likely to fit your vehicle.
Drivers commonly use tire size charts when replacing worn tires, considering plus or minus sizing, comparing metric and flotation tire sizes, or checking whether an alternative tire size stays within an acceptable overall diameter range. A chart provides a fast visual reference, making it easier to compare multiple tire sizes before making a decision.
However, a tire size chart should be used as a comparison tool rather than the only source for selecting replacement tires. Before installing a different tire size, always verify that it matches your vehicle manufacturer’s recommendations, wheel width requirements, load capacity, and available clearance to ensure safe operation.
Quick Guide to Tire Size Codes
Before using a tire size chart, it’s helpful to understand the basic format of a tire size. Most passenger vehicles use a code similar to 265/70R17, where each number represents a different measurement. You don’t need to memorize every detail—just enough to compare sizes correctly in the charts below.
| Tire Code | What It Represents |
| 265 | Tire width in millimeters |
| 70 | Aspect ratio (sidewall height as a percentage of the tire width) |
| R | Radial tire construction |
| 17 | Wheel diameter in inches |
These four measurements determine the tire’s overall dimensions and are the values you’ll see throughout the tire size charts on this page. If you’re comparing replacement tire sizes, matching these measurements correctly is essential for proper fitment.
If you want to understand every number and letter found on a tire sidewall—including load index, speed rating, P-metric, LT, ST, XL, and other markings—read our complete How to Read Tire Size Numbers guide before choosing a replacement tire.
Where to Find Your Correct Tire Size
Before comparing sizes in a tire size chart, you need to know the original tire size recommended for your vehicle. Using the manufacturer’s recommended size as your starting point helps you compare alternatives more accurately and reduces the risk of choosing an incompatible replacement.
1. Driver-Side Door Jamb Sticker
The driver’s side door jamb sticker is usually the most reliable place to find your vehicle’s original tire size. It typically lists the recommended tire size, wheel size, and cold tire pressure specified by the vehicle manufacturer. If the tires currently installed on the vehicle are not original, use the door sticker as your primary reference instead of the tire sidewall.
2. Owner’s Manual
Your owner’s manual provides the factory-approved tire sizes for your specific model and trim level. It may also include alternative tire sizes, seasonal recommendations, and additional information about load capacity or towing applications.
3. Current Tire Sidewall
The tire sidewall displays the size currently installed on your vehicle, such as 225/65R17. This is useful when replacing an existing set of tires with the same size. However, if you purchased the vehicle used or the wheels have been modified, the sidewall may not match the original factory specification.
4. Manufacturer Specifications
Many vehicle manufacturers publish official tire and wheel specifications for each model year and trim level. If the information from the vehicle, owner’s manual, or current tires doesn’t match, always verify the recommended tire size using the manufacturer’s specifications before selecting a replacement.
How to Use Tire Size Charts Correctly
A tire size chart is most useful when you compare the size you already have with the size you are considering. Start by finding your original tire size, then match it against the chart to see how the width, diameter, and overall fit change. This makes it easier to compare replacement options without guessing.
When you use a chart, focus on the row and column that match your wheel size or overall diameter. That helps you quickly narrow down the tire sizes that are most relevant to your vehicle. If you are comparing two different sizes, check whether the change stays within the manufacturer’s recommended limits and whether the new size still leaves enough clearance for safe driving.
A tire size chart is best used for comparison, not as the only source of truth. Before replacing tires with a different size, always confirm wheel width compatibility, load requirements, and fitment clearance so the new size works safely on your vehicle.
Tire Size Charts by Wheel Size
Use these charts to compare tire sizes by wheel diameter. Start with the same wheel size currently installed on your vehicle, then compare the available tire sizes before verifying fitment, load capacity, and your vehicle manufacturer’s recommendations.

Comparing Tire Sizes: Can You Change Your Tire Size?
Yes, in many cases you can change your tire size, but the replacement should be selected carefully. A tire size chart helps you compare dimensions and identify similar sizes, but it does not guarantee that every alternative will fit your vehicle safely.
When comparing tire sizes, the goal is usually to keep the overall tire diameter as close as possible to the original specification while ensuring the replacement matches your wheel size, load requirements, and available clearance. Even if two tires fit the same wheel diameter, differences in width or aspect ratio can change the tire’s overall dimensions.
Before choosing a different tire size, verify these key factors:
- Overall tire diameter remains close to the original size.
- The replacement fits your existing wheel width.
- Load capacity meets or exceeds the vehicle’s requirements.
- There is enough clearance for suspension and steering movement.
- The replacement follows your vehicle manufacturer’s recommendations whenever possible.
A tire size chart is an excellent comparison tool, but it should always be used together with manufacturer specifications and proper fitment verification before purchasing replacement tires.
Understanding Plus Sizing and Minus Sizing
When changing tire sizes, you may come across the terms plus sizing and minus sizing. These refer to changing the wheel diameter while selecting a tire that keeps the overall tire diameter as close as possible to the original specification.
Plus Sizing
Plus sizing means increasing the wheel diameter while using a lower-profile tire to maintain a similar overall tire diameter. This approach is commonly used to improve handling or achieve a different appearance without significantly changing the vehicle’s overall tire height.
Minus Sizing
Minus sizing is the opposite approach. It uses a smaller wheel with a taller sidewall tire to maintain a similar overall diameter. This setup is often preferred for winter driving, rough roads, or applications where additional sidewall height can improve ride comfort.
Why It Matters
Whether you choose plus sizing or minus sizing, the objective is the same: keep the replacement tire as close as possible to the original overall diameter while ensuring proper wheel fitment, load capacity, and vehicle clearance. Use the tire size charts on this page to compare similar sizes before verifying manufacturer recommendations.
Common Tire Size Mistakes to Avoid
Even with a tire size chart, choosing the wrong replacement tire can lead to fitment problems and affect vehicle performance. Before changing tire sizes, avoid these common mistakes.
Ignoring Overall Tire Diameter
Many drivers compare only the wheel size and overlook the tire’s overall diameter. Even small changes can affect speedometer accuracy, ground clearance, and vehicle handling. Always compare the complete tire dimensions, not just a single measurement.
Choosing Tires Based Only on Appearance
Larger or wider tires may improve the vehicle’s appearance, but they are not always the best choice. A tire should be selected based on proper fitment, intended driving conditions, and manufacturer recommendations rather than appearance alone.
Ignoring Load Rating
Every replacement tire should meet or exceed the vehicle’s required load capacity. Installing tires with an insufficient load rating can reduce safety and performance, especially when carrying passengers or cargo.
Installing replacement tires that don’t meet the required specifications can affect vehicle safety. The NHTSA tire safety recommendations also emphasize using tires that meet the vehicle manufacturer’s requirements.
Not Checking Wheel Width Compatibility
A tire may have the correct diameter but still be incompatible with the wheel if the width falls outside the recommended range. Always confirm that the replacement tire matches your wheel specifications.
Overlooking Clearance and Suspension Travel
Before installing a larger or wider tire, check for adequate clearance around the fenders, suspension components, and steering system. Insufficient clearance can cause rubbing during turning or suspension movement.
Expert Tips for Choosing the Right Tire Size
When using a tire size chart, the best choice is usually the size that stays closest to your vehicle’s original specifications while still meeting your driving needs. These practical checks can help you narrow down the right option faster:
- Keep the overall diameter as close as possible to the original size.
- Make sure the replacement tire fits your wheel width range.
- Confirm the load rating meets or exceeds the vehicle’s requirement.
- Check for enough clearance around the fenders, suspension, and steering components.
- Follow the vehicle manufacturer’s recommendations whenever possible.
- Use the tire size chart as a comparison tool, then verify the final choice with fitment details.
If you are comparing more than one size, use the chart to narrow the options first, then double-check the exact dimensions before buying.
Conclusion: How to Use Tire Size Charts with Confidence
A tire size chart makes it easier to compare tire dimensions, evaluate replacement options, and identify sizes that are likely to fit your vehicle. By starting with your original tire size and comparing overall diameter, wheel size, and other key measurements, you can make more informed decisions before purchasing new tires.
Remember that a tire size chart is a comparison tool—not the final authority on fitment. Always confirm the replacement tire matches your vehicle manufacturer’s recommendations, wheel specifications, load requirements, and available clearance before making a final decision.

FAQs About Tire Size Charts
Can I install a different tire size on the same wheel?
Sometimes, yes. The new tire must still match the wheel width range and remain compatible with your vehicle’s fitment and clearance requirements.
How accurate are tire size charts?
A tire size chart is very useful for comparison, but it should not be treated as the final fitment check. Always confirm the manufacturer’s specifications before buying.
What is the difference between wheel size and tire diameter?
Wheel size refers to the diameter of the wheel itself, while tire diameter refers to the tire’s overall outside height when mounted and inflated.
Should replacement tires match the original diameter?
The replacement size should usually stay as close as possible to the original diameter to help maintain proper fitment and vehicle performance.
Are tire size charts the same for all vehicles?
No. The best chart for a vehicle depends on its original specifications, wheel size, and the type of tire being compared.
Can a tire size chart guarantee proper fitment?
No. A chart is only one part of the decision. Final fitment also depends on wheel width, load rating, clearance, and manufacturer guidance.
