With these standards, you can find out everything from the load index rating to speed rating and more pertaining to your particular tire size.

General Standards

In addition to specific standards for each individual measurement, there are also general standards that apply across all types of tires. These include things like minimum tread depth requirements as well as maximum inflation pressures for different sizes of tires. By following these general rules when it comes time to purchase or install new tires, you can ensure that your vehicle will run safely and efficiently on whatever type of terrain you plan on driving on with your new set of wheels!

Reading Tire Sidewall Markings

Finally, another great way to determine your exact tire size is by reading the sidewall markings on your current set of tires. Most modern tires have markings on both sides indicating their exact measurements – including width, aspect ratio (percentage), rim diameter (inches), construction type (radial vs bias-ply) as well as other manufacturer-specific information such as speed rating or load index rating etc.. By taking note of all these markings before deciding on a new set of tires for your vehicle ,you can be sure that they will fit correctly without any issues!
