h - r surely approach that this tire is a radial. I - the diameter of wheel that this tire is supposed to suit. In this example 14. Tire rankings

utqg

patron magazines, tire shops and dr. Drivewire frequently use the utqg ratings when comparing tires. The initials stand for uniform tire exceptional grading, a best score gadget evolved by the department of transportation (dot). The gadget was designed to offer statistics to consumers as to the relative overall performance of passenger tires in the regions of treadwear, traction and temperature.

Utqg is simply one tool to use while choosing tires and it ought to no longer be your simplest manual. A utqg car parts tire rating looks as if this: a hundred and fifty a b

the variety a hundred and fifty shows the treadwear score. The first letter (a) suggests traction rating. The second letter (b) shows temperature rating. Treadwear

the treadwear grade is a comparative rating based totally on the wear price of the tire whilst tested beneath managed situations on a designated government check path. For instance, a tire graded one hundred fifty could wear one and a half of (1 1/2) instances as nicely at the government path as a tire graded 100. Regardless of what sort of utqc treadwear grade a tire might also get, actual performance will vary drastically based totally on using conduct, upkeep and differences in street conditions. Traction a, b, c

the utqg traction grade is based on a instantly ahead braking traction check. It is not based on cornering traction. The traction grades from highest to lowest, are a, b, and c. They represent the tire's capability to prevent on moist pavement as measured below managed situations on distinct government take a look at surfaces of asphalt and concrete. A tire marked c might be considered a bad traction tire. Temperature aa, a, b, c

the temperature grades are aa (the best), a, b, and c, representing the tire's resistance to the generation of warmth and its ability to burn up warmness whilst tested underneath managed conditions on a exact indoor laboratory check wheel. Sustained high temperature can purpose the cloth of the tire to degenerate and decrease tire existence, and excessive temperature can result in sudden tire failure. The grade c represents a stage of overall performance that all passenger automobile tires must meet underneath the federal motor automobile safety standard. Grades aa, a and b represent higher ranges of performance than the minimum required via regulation. The temperature grade is established for a tire that is nicely inflated and now not overloaded. Dr. Drivewire warns that immoderate speed, below inflation, or immoderate loading, either one after the other or in combination, can cause warmth buildup and feasible tire failure. Pace rating

u = 124 mph
h = a hundred thirty mph
v = 149 mph
w = 168 mph
y = 186 mph
z = 149 mph and over

overall performance tires

overall performance tires are those made usually in 15 inch diameter and large, with element ratios (profiles) of 35, forty, forty five, 50 or fifty five. Via using a tire with a decrease profile (shorter sidewall), you benefit quickness in guidance reaction and higher lateral stability. Speed ratings are typically h or greater. Most are velocity rated v or z. In preferred, performance tires are low profile tires with better pace scores and stepped forward traction characteristics.
