# What Does 88h Mean On A Tire

**What Does 88H Mean on a Tire?**

If you’ve ever found yourself searching for new tires for your vehicle, you may have come across a string of numbers and letters etched onto the sidewall of the tire. These markings can often be confusing, leaving you wondering what they actually mean. One such marking you may have encountered is “88H.” So, what does 88H mean on a tire? Let’s dive in and find out.

The number “88” in the tire marking refers to the load index of the tire. It indicates the maximum load capacity that the tire can safely support. The load index is a numerical value assigned to a tire that corresponds to a specific load capacity. Each load index value represents a certain weight limit, which is determined by tire manufacturers using industry standards.

Load index ratings typically range from 71 to 110, with each value corresponding to a specific weight limit. The weight limits associated with load index ratings can vary depending on the tire’s speed rating as well. In the case of the load index rating “88,” it corresponds to a weight limit of 1,235 pounds or 560 kilograms per tire when the tire is fully inflated.

It’s important to note that the load index value represents the weight the tire can handle when used on a vehicle traveling at a specific speed, typically 65 miles per hour or 100 kilometers per hour. If you plan on driving at higher speeds, you’ll need to consult the load index chart provided by the tire manufacturer to determine the appropriate weight carrying capacity.

To give you a better idea of what load index values correspond to different weight limits, here’s a general load index chart:

Load Index Value | Weight Limit (Per Tire)
—|—
71 | 761 pounds (345 kilograms)
80 | 992 pounds (450 kilograms)
88 | 1,235 pounds (560 kilograms)
95 | 1,521 pounds (690 kilograms)
110 | 2,337 pounds (1,060 kilograms)

It’s crucial to choose tires with a load index that meets or exceeds your vehicle’s recommended weight carrying capacity. Installing tires with a lower load index than required can compromise the safety and performance of your vehicle, while opting for tires with a higher load index than necessary is unnecessary and may result in a harsher ride.

## Tire Speed Rating

After the load index, the next part of the tire marking, “H,” refers to the speed rating of the tire. The speed rating indicates the maximum speed capability of the tire when it is properly inflated and loaded to its recommended weight capacity.

### Decoding Tire Speed Ratings

Tire speed ratings are represented by a letter that corresponds to a specific speed category. Each letter corresponds to a specific speed range, and it’s crucial to select tires with a speed rating that matches or exceeds the maximum speed capability of your vehicle.

Here’s a breakdown of the most common speed rating letters and their corresponding speed ranges:

– H: Up to 130 mph (210 km/h)
– V: Up to 149 mph (240 km/h)
– W: Up to 168 mph (270 km/h)
– Y: Up to 186 mph (300 km/h)
– ZR: Above 149 mph (240 km/h)

Choosing tires with an appropriate speed rating ensures optimal performance, handling, and safety, especially when driving at higher speeds. However, it’s worth noting that the vehicle’s overall speed capability is determined by various factors, including the vehicle’s design, suspension, and braking system.
