How we scoreWould You Recommend?
Treadwear Performance
Treadwear is vital to many things, not just how often the tires need replacement. Hydroplaning and wet weather are both critical factors that wear down your tire quickly. The warranty covers any defects in what you bought but only for a limited period or when there's minimal tread left on them.
Wet Perfomance
The wet performance score is a new thing that tire manufacturers are trying to achieve. The hydroplaning resistance, wet traction, and steering response all influence this new grading system.
The hydroplaning resistance is measured by the hydroplane depth test and the dynamic aquaplaning test, which measures how much water can be accumulated on the tire's surface before hydroplaning occurs.
Wet traction estimates the level of grip on wet pavement. Tread design with deep grooves dramatically improves confidence when driving in the rain as they channel the water out much better.
The vehicle's steering response largely depends on the tread depth, tire width, air pressure, and aspect ratio. Wide high-performance tires are equipped with a continuous center rib providing instant steering response.
Dry Perfomance
Tires with good dry performance should be able to perform smoothly and safely, even when cornering aggressively.
A dynamic cornering test is often used to assess cornering stability under dry conditions.
Dry traction level depends on many factors, including tread design, profile shape, and compounds.
The vehicle's steering response largely depends on the tread depth, tire width, air pressure, and aspect ratio. Wide high-performance tires are equipped with a continuous center rib providing instant steering response.
Comfort Perfomance
The comfort performance score is designed to measure the balance between ride quality and noise level.
The excellent ride quality means you do not feel the bumps or cracks on the road. Larger tires with thick and deep tread patterns decrease the number of jolts allowing you to glide over bumpy road textures.
If you would enjoy a quiet chat with the passengers while children are sleeping or listening to music, not the sound of tires, definitely pay attention to the noise score.
Winter Performance
Winter Performance score helps us understand if the tire is the appropriate option for winter conditions that your vehicle will face. Dedicated winter tires provide a firm grip when driving through snow and on ice. Performance winter tires boast a higher speed rating and better handling but deliver modestly lower ice and snow traction.
Tire size may be indicated in two formats:
– metric (P255/45R18 103H)
– high flotation (30x9.5 R15 104 F C)
In the metric system, P - stands for the passenger vehicles (LT - for Light Trucks, ST - Special Trailer) with a width of 255 millimeters, aspect ratio (sidewall height) equal to 45% of the tire height. R means it is radially constructed with a diameter of 18 inches. 103 denotes the tire's load index and H determines the speed rating.
In the high flotation system, the first number (30) is the overall diameter of the tire, the second number (9.5) is the width in inches.
Uniform Tire Quality Grade Standards (UTQG) were designed to offer consumers with useful information about the treadwear, traction, and temperature capabilities of their tires in order to make better decisions when purchasing new tires.
The maximum weight that a tire can carry is the greatest amount of weight it's designed to bear. Because load carrying capability is dependent on a tire's size and construction, as well as how much air pressure is actually utilized, maximum loads are measured with the tire inflated to an industry standard inflation pressure.
The maximum speed that a tire with this type of tread can safely travel for an extended amount of time is indicated by the tire speed rating, which is usually shown by a letter or two.
The highest "cold" inflation pressure that a tire is meant to contain is its maximum inflation pressure.
The tire weight is determined by the type and size of the tire. As the tread depth of the tire wears down over time, so does its weight.
Tires may be used on rims of varying widths while still fulfilling their intended function.
The measuring rim width is the common industry minimum rim width at which a tire must be mounted to validate that it meets design specifications.
The overall diameter of a tire is the outer diameter of the tire, measured in the center of the tread. This measurement is made without any load placed on the tire and after it has been properly mounted on its industry-assigned measuring rim and inflated to its test pressure after 24 hours.
The revolutions per mile figure indicates the number of times a tire rotates during one mile's travel.
