- LT: Gentle Truck
- ST: Particular Trailer
- P: Passenger Automobile
- T: Short-term, indicating an area saving spare tire or “donut.”
These classifications of tire are additional grouped by wheel measurement, with a given wheel measurement being additional categorized by different components similar to bolt sample and spacing.
Wheel measurement is indicated in millimeters or inches, with millimeters being much more widespread amongst producers at present.
It’s price noting that many shopper oriented publications and promoting will use whichever system of measurement is most typical and interesting to the shoppers of mentioned automobiles, and this will result in some confusion.
Wheel measurement is measured in three dimensions: Diameter, Width and Offset.
The diameter of the wheel measures the floor space of the wheel the place the bead of the tire rides. The width is the measurement of the internal distance between every bead and the offset is the gap from the wheel’s true centerline to the mounting floor, often expressed as half the width measurement above.
Typical shopper grade wheels typically characteristic these measurements so as starting with the diameter, then the width and lastly the offset however this isn’t a tough and quick rule.
Responsibility Ranking
In a given a class of tire, they are going to be additional grouped by what sort of responsibility they’re meant for, that means what kind of environments, purposes and efficiency is predicted from the tire.
Understanding these classifications can inform you at a look of what a tire is able to, and maybe extra importantly, what it’s not able to.
Asking an excessive amount of of a tire is a good way to speed up the place and even trigger an accident within the case of catastrophic failure.
Gentle-medium responsibility

Gentle-medium responsibility tires for vans and vans are comparable on this efficiency spectrum, however are anticipated to hold between 1,100 and three,300 lb on the drive wheel.
Gentle-medium responsibility tires are additional differentiated by pace scores, listed beneath.
Snow tires
As anticipated from the identify, these tires are designed for top efficiency, security and sufficient dealing with in wintry situations, significantly on snow and ice.
In comparison with different light- medium responsibility tires, these are designed with massive voids and gaps between the tread that’s designed to extend traction by giving snow, ice and slush room to compact.

Notoriously noisy, and may be a legal responsibility if emergency maneuvering is required on the pavement.
Excessive Efficiency
These tires are rated for each sturdiness and dealing with on the highest speeds achievable by automobiles on this class, as much as 168 mph for top efficiency tires, and as much as 186 mph for extremely excessive efficiency tires.
As you may anticipate, these usually are not famend for sturdiness or journey traits, typically described as harsh.
Run-Flat
A particular class of tire that’s able to sustaining a modicum of its efficiency envelope at a decreased pace within the occasion of a complete lack of air stress.
Stiff sidewalls preserve the form of the tire and stop injury to the rim of the wheel. Tires of this kind are sometimes put in on automobiles which don’t carry a spare tire. Notably, some will not be repaired if broken.
Race Automobile
For super-high efficiency automobiles, race automobile tires are employed, and are designed to maximise efficiency dealing with traits of the automobile on the expense of sturdiness and longevity. Out there in three subtypes, slick, rain and DOT (avenue authorized) race automobile tires.
Heavy Responsibility
For giant vans and comparable automobiles that present service on the roads and highways, heavy responsibility tires are employed and carry a load of 4,000 to five,500 lbs on the drive wheels. Generally seen mounted in tandem, or two to a facet, on drive axles.
Off-Highway
A subcategory of heavy responsibility tire sometimes used on agricultural tools, building automobiles and different massive and heavy working machines that transfer round on tender terrain that may be uneven or free.

P215/65R15 95H M+S
On this case, the code signifies the next, listed from left to proper:
P: Passenger Automobile, a tire for normal passenger automobiles.
215: Width, in millimeters. From facet wall to facet wall.
65: Separated by the slash, signifies side ratio of sidewall peak.
R: Signifies a radial tire. May very well be D for diagonal or B for bias belt. No letter on this place signifies a cross-ply tire sort.
15: Diameter of wheel this tire is designed to suit, in inches. Often seen in millimeters, and proven as a 3 digit quantity.
95: Load index quantity. Cross referencing this on the ETRTO requirements desk will reveal the load score of the tire. On this case, 1,520 lbs.
H: The pace score of the tire, generally seen earlier within the sequence earlier than or after the side ratio.
M+S: Brief for “Mud and Snow”; an All-Season tire sort.
Although the lengthy strings of characters may seem baffling to the uninitiated at first, understanding the code is sort of easy and with just a bit little bit of research you’ll quickly have the one related tables memorized within the case of load indexes and pace scores.
