How is a tire size read?
The word “P-Metric” (meaning tires built to certain standards in the United States and meant for Passenger vehicles) appears at the beginning of the phrase “Tire Size,” which identifies the tire as such.
A tire is said to be Euro metric if its tire size begins with no letters. The load capabilities of P-Metric and Euro-Metric tires may differ.
Light truck tires are identified by the initials “LT,” either at the start or end of the tire size. Some light vehicles come from the factory with “LT” type tires. In comparison to passenger tires, these tires often need greater inflation pressures.
For information on the required tire size and inflation pressure for your vehicle, refer to your owner’s manual or tire placard.
Tire Width
Is the tire’s breadth, measured from sidewall to sidewall in millimeters. The tire width is indicated by the first three digits of the tire size. For instance, the width of a tire with the size P215/65 R15 is 215 millimeters.
Aspect Ratio
is the proportion of the tire’s cross-sectional height to its width. The aspect ratio is the two-digit figure that follows the slash in a tire size. For instance, the 65 indicates that the height is equivalent to 65 percent of the tire’s width in a tire of size P215/65 R15. The sidewall of the tire will be larger the larger the aspect ratio.
Wheel Diameter
The wheel’s size is determined by measuring it from end to end. It provides us with the wheel size that the tire is meant to fit. A tire with the size P215/65 R15 is designed to fit a 15″ diameter wheel.
Load Index
shows the maximum load that a properly inflated tire can support. The tire sidewall will also list the maximum load in pounds and kilograms. Study up on tire load index.
Speed Rating
reveals the maximum speed that a tire is capable of. Frequently, speed ratings are matched to the vehicle’s top speed. For instance, a tire with an H-speed rating can travel at a top speed of 130 mph (210 km/h). Goodyear does NOT advise driving faster than the posted speed limits. Study up on tire speed rating.
Tire Identification Number
the string of characters that come after the letters “DOT.” The TIN contains up to 12 numbers and letters to specify the factory, the week and year the tire was made, as well as the location of the plant.
UTQG
stands for Uniform Tire Quality Grading, a rating system created by the U.S. Department of Transportation to give consumers information to assist them in making tire purchases based on their respective levels of traction, treadwear, and temperature tolerance.
The wet traction of a tire is shown by its traction grade in a controlled test. An “AA” rated tire provides exceptional traction in slick weather.
Temperature ratings show how well a tire can endure and dissipate harmful heat. Higher temperature grade tires may function at faster speeds.
The expected treadwear of a tire is predicted using treadwear grades, which are based on established government tests. For instance, a tire should last twice as long as one with a treadwear grade of 200 than one with a grade of 100.
Has the Audi A4 from 2021 got a spare tire?
Unattended flat tires can have a catastrophic impact on the rest of your car. Drive your A4 Quattro as little as possible up until it is fixed or replaced to lessen the chance of harm coming to the wheels, alignment, or already-fragile tire!
Quick remedies have their pros and cons. Don’t rely on them to keep you on the road for too long; they’ll assist you get your Audi A4 Quattro to Firestone Complete Auto Care. A Bridgestone or Firestone tire warranty may potentially be nullified by using a temporary sealant.
The majority of extra tires are not built for distance or speed, despite the fact that this may sound fantastic in theory. Don’t utilize the little spare tire that likely resides inside your 2021 Audi A4 Quattro as an alternative for having your tire repaired because it is only designed to be used for a short period of time.
