What Is Load Rating on Tires? (And Why It Matters More Than You Think)
When it’s time for new tires, most drivers focus on tread life, brand, or price. But there’s one number that often gets overlooked, and it’s one of the most important for safety and performance: load rating on tires.
At J.C. Lewis Motor Co., we help drivers make smarter tire decisions every day. In this guide, we’ll answer the common question “what does load rating mean on tires?”, learn how to read a tire load ratings chart, and discover why choosing the right rating matters more than you might think.
What Does Load Rating Mean on Tires? 🛞
The load rating on tires (also called the load index) tells you how much weight each tire can safely support when properly inflated.
This rating is represented by a number (usually found on the tire’s sidewall) next to the tire size. While it may look small, that number plays a big role in how your vehicle handles weight, passengers, cargo, and towing.
In short: Your tires are only as strong as their load rating allows.
Why Load Rating Matters More Than You Think
Choosing the wrong load rating on tires can affect far more than just wear.
Here’s why load rating is critical:
Safety: Overloading tires increases the risk of blowouts
Handling: Proper load ratings improve stability and braking
Tire Life: Under-rated tires wear faster and unevenly
Performance: Especially important for trucks and SUVs
If you regularly haul cargo, tow trailers, or load up the family for road trips, tire load ratings are non-negotiable.
How to Read a Tire Load Ratings Chart
A tire load ratings chart converts the load index number into an actual weight capacity (measured in pounds).
For example:
Load Index 95 = approx. 1,521 lbs per tire
Load Index 105 = approx. 2,039 lbs per tire
Multiply that number by four, and you’ll see how much total weight your tires are designed to support.
Your vehicle’s recommended load rating is listed in:
The owner’s manual
The driver-side door jamb sticker
Manufacturer specifications
Passenger Tires (P-metric) vs Light Truck (LT) Load Ratings
Not all tires are built the same.
Passenger (P-metric) tires are designed for comfort and efficiency
Light Truck (LT) tires offer higher load ratings for towing and hauling
If you drive a truck or SUV and frequently carry heavy loads, upgrading to a higher load rating on your tires can make a noticeable difference in durability and control.
What Happens If Your Tire Load Rating Is Too Low?
Running tires with an insufficient load rating can lead to:
Excessive heat buildup
Poor handling under weight
Premature tire failure
Reduced fuel efficiency
Even if the tires “fit,” they may not be safe for how you actually use your vehicle.

Tire Load Rating FAQs
+ What is load rating on tires?
The load rating on tires (also called the load index) indicates the maximum weight a tire can safely carry when properly inflated. Each tire has a numerical rating that corresponds to a specific weight capacity. Choosing the correct load rating helps ensure safe handling, proper braking, and longer tire life.
+ How do you find the load rating on tires?
You can find the load rating printed on the sidewall of the tire, usually next to the tire size. It appears as a number (for example, 95 or 115) and can be matched to a tire load ratings chart to see the exact weight capacity. You can also find recommended ratings on the driver-side door jamb sticker or in your owner’s manual.
+ What does load and speed rating mean on tires?
The load rating tells you how much weight the tire can carry, while the speed rating indicates the maximum safe speed the tire can sustain. Both ratings work together to ensure your tires match your vehicle’s performance, weight, and driving conditions.
+ What load rating tire is recommended for an F-250?
Ford F-250 trucks typically require Light Truck (LT) tires with higher load ratings, especially if towing or hauling. The exact load rating depends on your truck’s configuration and usage, so it’s best to follow the manufacturer’s recommendations listed on the door jamb or consult a tire professional.
+ What tire load rating do I need?
The load rating on tires you’ll need depends on:
Your vehicle’s weight
Passenger and cargo load
Towing or hauling habits
Always meet or exceed the manufacturer’s recommended load rating to maintain safety and performance.
+ Can you mix tires with different load ratings?
It’s not recommended to mix tires with different load ratings. Doing so can cause uneven handling, braking issues, and increased wear. For best results, all four tires should have the same load rating.
+ Do tires with a higher load rating last longer?
Tires with higher load ratings are built stronger and may last longer under heavy use. However, longevity also depends on proper inflation, alignment, driving habits, and tire maintenance, not just load rating alone.
