The given 285/65 R18 was produced in the US and belongs to the On-/Off-Road Commercial Traction. Meant for off-road traction, heavy-duty tires provide confidence driving through the snow with sturdy tread patterns biting into loose or icy surfaces. Each tire category is meant for a certain type of vehicle, road conditions and driving style.
285 - first three numbers measure the width in millimeters from sidewall to sidewall
65 - two-digit number following the slash mark is the aspect ratio telling you how tall the profile is. It is calculated in percentages by dividing the tire’s height by its width.
R18 - "R" stands for Radial type of construction. It is followed by the wheel diameter in inches the tire is meant to fit.
The tire's UTQG grade assesses the tire's ability to resist the effects of tire wear, tire traction, and tire temperature. The higher the UTQG treadwear rating, the longer your tires should last. UTQG ratings generally range from 100 to 600. The UTQG treadwear grade is stated in terms of the tire's wear rate when tested under controlled conditions on a specified government test track.
The treadwear rating for this tire is graded
The traction grade is marked with the letter , meaning the coefficient of wet traction is on asphalt and g on concrete.
Tires graded effectively dissipate heat up to a maximum speed that is mph.
A tire's maximum load specifies the most weight the tire is allowed to carry when inflated to an industry assigned inflation pressure.
The maximum load for the given tire is limited to 125, it can support 3640 pounds / 1650 kg at maximum air pressure.
The tire speed rating, marked by a letter or two, is the top speed capability it can safely travel for a sustained amount of time.
This tire is W-rated for a maximum allowed speed of 0 / 0 kmh.
The tire’s maximum inflation pressure, stamped on the tire sidewall near the bead close to the wheel, is measured in pounds per square inch (psi) or kilopascals (kPa).
In "cold" conditions, this tire can withstand the maximum inflation pressure of 80 psi.
The tire weight depends on the tire type and its overall size. As the tire’s tread depth wears down over time, you can expect the weight of the tire also to reduce.
The actual tire weight is 56.
Rim width range comprises the scale for the minimum and maximum rim width range.
The assigned measuring rim width range confirms the tire can be mounted on wheels with the rim width range between 8-10"".
The measuring rim width is the industry standardized rim width upon which the tire must be mounted in order to confirm it meets its dimensional targets.
The standard measured rim width for the given tire is 18/32".
The overall diameter of a tire is the sum of the wheel diameter and the sidewall height multiplied by 2.
The overall diameter of the tire equals 32.59
Revolutions per mile spec counts the number of times a tire rotates when covering the distance of one mile. It is impossible to calculate by pure math as the tire tread and sidewall bend and stretch when the vehicle\s weight presses the tire.
The specified tire is expected to make the following number of full spins per mile: 618.87/mi.
This label specifies the country where the tire was manufactured.
This particular tire was produced in US.
