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.
What is the Kia Optima’s bolt pattern for 2015?
The bolt pattern on the 2015 Kia Optima SX Turbo is 5-114.3 mm. This indicates that there are 5 lugs and that the circumference of the circle formed by the lugs is 114.3 mm, or 4.5 inches.
Can my car have 22-inch rims?
Yes, you might be able to mount 22s, however you might need to use a tire with a very low profile. By examining your car, a reputable tire and wheel shop will be able to advise you on what can be done safely. It was useful to 16 people.
Can I use tires of a different size on my car?
Simply simply, the bigger the tire, the better the traction your car has. A tire’s width affects how much surface area it covers on the road. According to iSee Cars, your vehicle has more to grab onto due to the increased touch with the pavement, which improves handling and maneuverability.
Does tire size thus actually matter? Yes, to answer briefly. But is wheel size important? It varies.
Tires and wheels are two different concepts. The wheel arrangement includes tires. For instance, even though the rims on your car are a specific size, you can buy alternative tire sizes to fit them as long as the middle of the tire is the right size. Having said that, a car with larger rims will frequently be able to accommodate bigger tires than other cars.
Bigger Wheels = Bigger Bills
In general, larger wheels and tires are preferable for improving traction on your vehicle. According to Consumer Reports, larger tires can come at a higher cost. Find the ideal balance between size and your spending limit. Even while you might not initially notice a price increase if you choose larger wheels when you buy your car, the cost of replacing larger wheels and tires will be more for you than for someone who chooses smaller wheels.
When buying replacement tires, you should stick with the tire size you’ve chosen for your car. This is because a tire of a different size might throw off your speedometer and potentially mess up the calibrations of your car’s stability and anti-lock braking systems. Both moving to smaller tires and larger tires fall under this. Altering to larger tires with an inadequate sidewall height increases the possibility of inaccurate speedometer readings while also endangering the wheels, tires, and suspension system of your car.
Your speedometer and odometer shouldn’t change, though, if you match larger-diameter wheel sizes to low-profile tire sizes. Because of this configuration, your tires’ sidewalls are shorter, which makes them stiffer and increases the risk of blowouts when you strike a pothole.
When replacing your tires, make an effort to utilize the same brand and size. If you mix and match, your car will have various tire threads, which can lead to spinouts and a loss of control.
Can I substitute 245 tires for 235?
The short answer is yes, although 235/50-18 tires will have a 10mm (0.4 in) lower overall diameter than 245/50-18 tires. Odometer and speedometer will only be minimally affected; for example, the speedometer will read roughly 5% too high.
Another alternative is to go from 245/50-18 to 235/55-18, although in this case your speedometer and odometer would read roughly 2 percent lower due to the overall tyre diameter increasing by 13mm (0.5 in).
What degree of tire size variation is acceptable?
We advise staying within 3% of the original tire’s diameter and height when changing tire sizes. You run the danger of having brake failure if you use more than this.
