What Is the Load Rating on Budget Tires? | Load Index Explained

You can determine a budget tire’s load rating by reading the Load Index or Load Range number on the sidewall — it varies by size and model, not by price. These codes tell you the maximum weight each tire can safely carry at its rated pressure. A typical budget passenger tire carries a Load Index between 88 and 105, supporting roughly 1,235 to 2,149 pounds per tire. This guide explains both rating systems, shows where to find the code, and gives real examples for matching the right rating to your vehicle.

What Does the Load Index Mean?

The tire load rating system uses a 2- or 3-digit Load Index, appearing right before the speed rating letter in the tire size code. It represents the maximum weight a tire can support at its maximum rated pressure. In the size code “225/55R18 98H,” the number 98 is the Load Index, equaling 1,653 pounds per tire at rated pressure. Budget passenger tires typically carry Load Index values between 88 and 105.

Here are common Load Index values and what they mean:

Exceeding the load rating at any speed risks premature wear, poor handling, and blowouts — whether the tire cost $80 or $200. The sidewall number is the binding limit regardless of price tier. To find your vehicle’s required Load Index, check the driver’s side door jamb placard or owner’s manual. Multiply the single-tire capacity by four — the total must exceed the vehicle’s GVWR.

What Is Load Range?

For light trucks, SUVs, and heavy-duty vehicles, a letter code called Load Range indicates the tire’s internal construction strength and maximum air pressure capacity. Budget tires in these categories often carry Load Range SL, XL, C, D, E, or G. The official tire load rating guide from Michelin covers this system in detail.

• Standard Load (SL): 4-ply equivalent, up to 36 psi
• Extra Load (XL): 4-ply equivalent, up to 42 psi
• Load Range E: 10-ply equivalent, up to 80 psi, carrying 3,000–3,640 lbs per tire
• Load Range G: 14-ply equivalent, up to 110 psi

A common mistake is using Standard Load tires on a truck that needs Extra Load or Load Range E. Always match or exceed the load range on the vehicle’s door placard. The Load Range determines the maximum pressure the tire can handle — SL tires top out at 36 psi, while Load Range E tires can handle up to 80 psi. Modern ply ratings are equivalents — a 10-ply rating doesn’t mean ten physical layers, just the strength of that construction using modern synthetic cords.

How to Check Load Rating on a Budget Tire

Checking the load rating on any budget tire takes about thirty seconds.

Step 1: Find the sidewall code. Look for the tire size string — something like “225/55R18 98H” or “35X12.50 R17/E.” The number before the speed letter is the Load Index. The letter after the size (if present) is the Load Range.

Step 2: Read the number. Match the Load Index to a chart (like the one above) to find the weight in pounds. For Load Range tires, the letter tells you the max pressure and ply-equivalent strength.

Step 3: Check your vehicle’s spec. Look at the door jamb placard or owner’s manual for the recommended tire size and load rating. Never install a tire with a lower load index or range than what’s listed. For example, four tires each rated at 1,477 lbs (Index 94) give a total capacity of 5,908 lbs — enough for many midsize SUVs.

Once you know the load rating your vehicle needs, the best cheap tires for your vehicle can help you find a set that meets the spec. Multiply the single-tire capacity by four and compare it to the GVWR listed in the owner’s manual. If the total exceeds the GVWR, the tires are adequate for your vehicle’s fully loaded weight.

The load rating on a budget tire isn’t about the price — it’s about the numbers on the sidewall. Read the Load Index or Load Range code, check your vehicle’s placard, and always match or exceed the spec. That’s how you stay safe regardless of what you paid.

FAQs

Can I use a tire with a higher load rating than my vehicle requires?

Yes, using a tire with a higher load index or load range than required is safe and often recommended for towing or heavy loads. The tire can carry more weight, but the ride may feel stiffer at normal pressures. Just don’t go lower than the vehicle’s spec.

Does a higher load rating mean a rougher ride?

Generally yes — tires with higher load ratings have stiffer sidewalls and heavier construction, which transmit more road imperfections into the cabin. Standard Load tires usually ride softer than Extra Load or Load Range E tires on the same vehicle.

Is the load rating the same as the speed rating?

No, the load rating (the number before the speed letter) and the speed rating (the letter after the load index) are separate specifications. A tire can have a high load index but a moderate speed rating, or vice versa. Both are molded on the sidewall for easy reference.
