what is the difference between tire 20560R15 AND P20560R15?

Answer 1

Absolutely nothing. The P stands for passenger, but is relatively worthless in reading the sidewall of the tire.

The 205 is the MM width of the tread from sidewall to sidewall when the tire is properly inflated. The 60 is the aspect ratio, the percentage of height of the sidewall to the width of the tire (in this case the height of the sidewall is 60% of the width of the tire. The R stands for radial construction and the 15 is the rim size.

The most important thing you should look for is the speed rating of the tire which will follow the previous set of numbers. The speed rating should meet or beat what you have on the vehicle.

Answer 2

the three digit quantity is the length of the tire measured down the sidewall, through the tread, and up the different sidewall, so the 255 in 20mm longer in that length. The 70 is the element ratio, that is, the share of the three digit quantity which consistutes the sidewalls. The decrease the quantity, the shorter the sidewall. 70 is a effective favourite beefy sidewall. A low quantity like a 50 or 40 5 is a authentic short sidewall, like on a race vehicle. in case you position the 255's on your truck, which will be a extremely taller tire, you ought to make efficient the rubber gained't hit some thing contained in the wheelwell, notwithstanding it isn't any longer a drastic replace so ought to fit ok. The speedo will be off extremely.

Metric or Euro metric sized tires are the ones without the "P" at the beginning.
P-metric sized tires are the ones with the "P" at the beginning of the tire size they were introduced in the United States in the late 70s and are installed on vehicles primarily used to carry passengers including cars, station wagons, sport utility vehicles and even light duty pickup trucks. Their load capacity is based on an engineering formula which takes into account their physical size (the volume of space for air inside the tire) and the amount of air pressure (how tightly the air molecules are compressed). Since all P-metric sizes are all based on the formula for load, vehicle manufacturers can design their new vehicles (weights and wheelwell dimensions) around either existing or new tire sizes.
Metric or Euro metric sized tires are the ones without the "P" at the beginning Using metric dimensions to reflect a tire's width actually began in Europe in the late 60s. However, since Euro metric sizes have been added over time based on the load and dimensional requirements of new vehicles, the tire manufacturers designed many new tire sizes and load capacities around the needs of new vehicles. Not quite as uniform as creating sizes using a formula, but they got the job done.Euro metric and P-metric tires in the same size (i.e. P205/60R15 & 205/60R15) are equivalent in their dimensions with just slight differences in their load capacity calculations and inflation pressure tables. So if Euro metric and P-metric tires have the same numeric size, the same tire performance category and the same speed rating, the two are considered equivalent and interchangeable if used in axle pairs or sets of four. Simply continue to follow your vehicle manufacturer's recommended inflation pressures provided in the vehicle's owner's manual or on the vehicle tire placard (usually found on the door jamb or on the glovebox or counsel door) for either size tire.

The 205- is the section width (linear distance between outside sidewalls of an inflated tire without any load.)
The 60- is the Aspect Ratio(Relationship of section height to section width. A lower aspect ratio has a shorter sidewall & wider tread.)
The R- is Radial Construction Type (most tires today are radial. Other types include belted bias and Diagonal bias.)
The 15- is the rim size (Always verify the rim size listed on the tires sidewall and the wheel size are the same.

I could say nothing and p stands for passenger vehicle. But then I want the big 10 points too. So check the URL out and it explains what the letters and number mean on a tire, complete with pics. TIP - bookmark the site

absolutely nothing. The P stands for passenger tire.
