They are called tire markings and they care all kinds of pleasant info, from load energy, mould and interpretation type, all the street to tire vastness. You can decipher the tire proportions markings using this sequence as an process: M + S P 185/80 R15. It is the newest and straightaway widely used metric measuring course.

Instructions
1. Stare at the beginning two letters: "M + S." This niggardly this tire is designed to properly propel over mud and snow on the municipality without yet occupation. Be careful, though--this does not mercenary this is an all-terrain tire unless exceptionally specified.
2. Compare the attached packages to the one on your own tires: "P." It is the one you Testament detect most oftentimes in cars environing the streets and roads. That is since "P" stands for passenger. Tires with a "P" are specifically make-believe for passenger vehicles.
3. Comment the adjoining three-digit cipher: 185. It might differ from the one on your tires. This number means that the tire is 185 mm at its section width--that is, from the outside of the tire wall all the way across to the outside of the opposite wall.
4. Refer to the next number after the forward slash: 80. This number is given as an aspect ratio of height to width. Height is measure from the inner-tire circumference to the top of the tread, the part of the tire surface that comes in contact with the road. In the example, the tire's height is 80 percent of the width. The smaller the aspect ratio number is, the wider and shorter the tire will be.
5. Pay particular attention to the next letter.6. Take a look at the last number and compare it with yours: 15. This will give the rim size on your vehicle.
The example comes with an "R" designation. That means it is a radial tire--it has plies running across with extra belts between the plies and the top surface for a stronger tread. Other common designations are "B," for belted bias tires, which provides a smooth ride and traction, and "D" for bias ply tires, which provide a smooth ride on rough terrain but offer weak plies and tread. The example uses a 15 inch diameter rim size. This is the number a salesperson wants when asking for the tire size.
