What Does 111H Mean On A Tire? | Load And Speed Decoded

111H on a tire means a 2,403-pound load rating per tire and an H speed rating approved for up to 130 mph.

If you’re asking, “What Does 111H Mean On A Tire?”, you’re looking at the tire’s service description. That short code tells you two things at once: how much weight one tire can carry and the top speed category the tire passed in testing when it’s inflated the right way and carrying the right load.

That makes 111H more than sidewall clutter. It helps you match a replacement tire to your vehicle, avoid a load mismatch, and skip the guesswork when two tires share the same size but not the same rating. Size alone is not the whole story.

What Does 111H Mean On A Tire? On The Sidewall

The number 111 is the load index. On a passenger tire, load index 111 equals 2,403 pounds for one tire when it is inflated to the proper pressure. Multiply that by four tires and you get 9,612 pounds on paper, though your vehicle’s own axle and weight limits still decide what it may carry on the road.

The letter H is the speed rating. An H-rated tire is built for sustained speeds of up to 130 mph under controlled test conditions. That letter is not a target speed for daily driving. It is a heat and durability rating tied to the tire’s design.

So when you read 111H, the plain reading is this: one tire can carry 2,403 pounds, and the tire falls into the H speed category. Both parts matter when you shop for replacements.

Why The Two Characters Matter

A tire can match your wheel size and still be wrong for the vehicle if the load index is too low. The same goes for the speed letter. Car makers set a minimum service description for a reason. It keeps the tire in the range the suspension, braking, and weight balance were built around.

• Load index 111 tells you the weight limit for one tire.
• Speed rating H tells you the tire’s speed class.
• Together they help you sort safe replacements from look-alike tires that do not meet spec.

Where 111H Sits In A Full Tire Code

Say your sidewall reads 245/60R18 111H. The first part gives the tire’s size. The last part gives the service description. That split is where many drivers get tripped up.

Breaking Down A Sample Marking

• 245 = tire width in millimeters
• 60 = sidewall height as a percentage of width
• R = radial construction
• 18 = wheel diameter in inches
• 111 = load index
• H = speed rating

Michelin’s tire sidewall markings page lays out the same format: the number-letter pair at the end is the service description, and replacement tires need to meet or exceed the maker’s spec.

That last point is where shoppers save themselves trouble. Two tires may both be 245/60R18. One might be 105H, another 111H. They fit the same wheel, yet they do not carry the same load.

Load Index Numbers Near 111

If you are comparing tires online, you’ll often see nearby load indexes listed side by side. A small step up or down changes the weight rating by more than many drivers expect. Here’s the range around 111.

Load Index	Max Load Per Tire	What It Means In Practice
105	2,039 lb	Lighter spec often seen on smaller crossovers and sedans
106	2,094 lb	A small step up in carrying capacity
107	2,149 lb	Common on some midsize SUVs
108	2,205 lb	Often paired with all-season touring tires
109	2,271 lb	Useful jump for heavier trims
110	2,337 lb	Close to 111, but still lower
111	2,403 lb	The rating stamped in 111H
112	2,469 lb	One step higher than 111
113	2,535 lb	Seen on heavier SUV and van fitments

Those numbers come from the standard load index chart used across the tire industry. Goodyear’s load index and speed-rating chart lists load index 111 at 2,403 pounds and H at 130 mph, which is why the code can’t be read as a trim mark or a model label.

Why 111H Matters When You Replace Tires

When you buy a replacement tire, matching the size is step one. Matching the service description is step two. Skip that second step and you can end up with a tire that fits the wheel but does not fit the job.

That shows up in a few ways:

• The vehicle may feel less settled with passengers or cargo.
• The tire may run hotter under load.
• You may fall below the rating listed on the door-jamb placard or in the owner’s manual.
• A tire shop may flag the mismatch during installation.

That speed letter gets brushed off more often than it should. An H tire is not only about top speed. The rating also ties into how the tire handles heat at speed. That is one reason car makers do not treat the letter as an optional extra.

Speed Symbol	Max Speed	Typical Fitment
S	112 mph	Family sedans and vans
T	118 mph	Mainstream sedans and crossovers
H	130 mph	Sport sedans, coupes, many SUVs
V	149 mph	Sportier passenger cars
W	168 mph	High-speed performance cars
Y	186 mph	Higher-speed performance fitments

Can You Go Higher Or Lower Than 111H?

Going Higher

A higher rating is often allowed. You can move from 111H to something like 111V or 113H if the tire size and vehicle spec still line up. The trade-off may be ride feel, tread life, price, or winter grip, depending on the tire.

Going Lower

Dropping below the vehicle maker’s minimum is where trouble starts. A lower load index cuts carrying capacity. A lower speed letter may also put the tire below the spec the vehicle was built around. Michelin says replacement tires should meet or exceed the manufacturer’s stated load and speed rating.

That is why 111H should be treated as a floor unless your door placard or manual says otherwise. If your original tire shows 111H, a tire marked 107H or 111T is not an equal match even if the size looks right.

Mistakes Drivers Make With 111H

Most mix-ups come from reading only the size and skipping the rest of the sidewall. These are the ones that show up most often:

• Reading 111 as PSI. It is not air pressure. It is a chart-based load index.
• Treating H as a handling grade. It is a speed class, not a comfort score.
• Thinking all same-size tires are equal. Size can match while load and speed do not.
• Using the tire sidewall max pressure as the car’s set pressure. The vehicle placard sets your normal inflation target.
• Counting the four-tire total as the vehicle limit. The vehicle’s own weight ratings still rule.

What 111H Usually Tells You About The Tire

On many passenger vehicles, 111H shows up on heavier crossovers, SUVs, and some vans where the tire needs more carrying capacity than a small sedan tire. The H letter also hints that the tire sits above basic commuter speed classes like S and T, yet below performance letters such as V, W, and Y.

That mix makes 111H a common middle-ground service description. It gives solid load capacity and a broad everyday speed class without stepping into the higher-cost end of the performance range.

If you only wanted the plain meaning, here it is again: 111H means one tire is rated to carry 2,403 pounds, and the H letter marks a speed class up to 130 mph. Match that code to your vehicle’s placard and manual when you buy tires, and you’ll be reading the sidewall the way tire shops do.
