Tire Size
Below
taken from:
Typical Tire Markings
A- Tire width
B- Aspect Ratio. The smaller the number the lower profile of the tire. In metric this is a ratio between height and width. ex. A 170/80 means the width is 170mm, and the height would be 80% of that. )
C- Rim diameter
D- Load capacity
E- Tire speed rating (ex. S=112mph, H=130mph, V=149mph, W=168mph)
F- Tubeless (TL) or Tube Type (TT) tire.

Tire Size Meanings
A: TIRE TYPE The first letter
in the code tells you what class of tire it is.
P stands for passenger vehicle tire. P-class tires include cars, SUVs, crossovers, minivans and smaller pickup trucks.
LT means light truck tire, designed for vehicles that are towing trailers or have ¾- and 1-ton load capacity.
ST stands for Special Trailer. These tire sizes are meant for trailers, including fifth wheels and other travel trailers, boat trailers and utility trailers.
If there’s no letter before the first number, you have a metric tire most commonly referred to as European size. It’s also measured in millimeters but may have different load capacity than a P or LT tire.
B: TIRE WIDTH The three-digit number following the letter is the tire’s width (from side to side, looking at the tire head on) in millimeters. Also called the section width, this measurement is taken from outer sidewall to inner sidewall.
C: ASPECT RATIO The forward slash separates the tire width number from the two-digit aspect ratio. The bigger the aspect ratio, the higher/taller the tire’s sidewall, or “profile” as it’s sometimes called.
The aspect ratio is a percentage. It’s the height of the sidewall measured from wheel rim to top of the tread, expressed as a percentage of tire width. In other words, it’s sidewall height divided by tire width.
In this example, the aspect ratio is 65, meaning the sidewall is 65 percent as high as the tire is wide. To get the sidewall height, take the tire width of 215 mm and convert it to inches (8.46). Then multiply this by .65 and you get 5.5 inches, the sidewall height in inches.
D: CONSTRUCTION TYPE This single letter tells you about the internal construction of the tire.
R is for radial tires, the industry standard for most tires today. They have better road grip, lower rolling resistance for better gas mileage, ride comfort and durability than previous generations of tires. In a radial tire, the plies — layers of strong cords made of a blend of polyester, steel and fabric and coated with rubber — are laid perpendicular to the direction of travel.
P stands for passenger vehicle tire. P-class tires include cars, SUVs, crossovers, minivans and smaller pickup trucks.
LT means light truck tire, designed for vehicles that are towing trailers or have ¾- and 1-ton load capacity.
ST stands for Special Trailer. These tire sizes are meant for trailers, including fifth wheels and other travel trailers, boat trailers and utility trailers.

Xiaomi m365 Tire pressure
At a load of 50-70kg: the front wheel is 35-40psi, the rear wheel is 40-50psi.
At a load of 70-90kg: the front wheel is 40-45psi, the rear wheel is 45-55psi.
At a load of 90-100kg: the front wheel is 45-50psi, the rear wheel is 50-60psi.
At a load of more than 100 kg: it is recommended to pump up to 50-55psi front and 60-65psi rear, but careful driving is recommended.

The risk of puncture increases with weight gain.
