One of These Things is Not Like the Other!

Often times, you'll see two different listings for seemingly identical tires, but they have two different prices. What in the world is going on with that?

Tire manufacturers will give different part numbers to the same model of tires if the tires have a different sidewall styling, speed rating, load index or O.E. designation. These differences in the tires are enough to earn different part numbers and prices which are subject to the ever-changing market. Remember, if the tires have the same size, that means they will have essentially the same dimensions. One tire is not going to be "low profile" and the other one "not low profile" because that's not how tire sizes work. Also low profile is a relative term, not a strict set of sizes.

Manufacturers vary their offerings to try and cover as much of the market as possible. Some people like blackwall tires, some people like tires with white letters, therefore a lot of times you'll see both options. Some car manufacturers work with tire manufacturers to tune a tire slightly to sell as Original Equipment and make their car handle a certain way, but the changes are usually not apparent and the information on what was changed is most often proprietary. That's why you will see a certain tire listed, then right below you'll see the same tire, but it says "N3 Porsche" or "MO Mercedes" below it. 

Here are the most common places to find differences that are not immediately apparent:

Service Description - Speed Rating

Original Equipment Designation - Service Description

Sidewall Style
