What do the 3 numbers mean on tire size?
B: TIRE WIDTH The three-digit number following the letter is the tire’s width (from side to side, looking at the tire head on) in millimeters. It’s the height of the sidewall measured from wheel rim to top of the tread, expressed as a percentage of tire width. In other words, it’s sidewall height divided by tire width.
What does the 265 70r17 mean?
This number indicates that your tire has a width of 265 millimeters. 70. This number means that your tire has an aspect ratio of 70%. In other words, your tire’s sidewall height (from the edge of the rim to the tire’s tread) is 70% of the width. In this case, the sidewall height works out to be 185 millimeters.
Can I use 60 instead of 65 tires?
Physically, yes they will fit. It is recommended to stay within 3% of the original tire size on the car though. The size you have is 3.09% smaller, so not recommended. You could go with 205/60-15 though if you can get a better deal on that size.
What do the letters on tires mean?
The number is the load rating, or the amount of weight that it can handle. The letter is the speed rating, or the maximum speed the tire is built for. As an example, a tire rated 90R could safely carry 1,323 pounds and travel at 106 mph.
Can I use 235 tires instead of 225?
Yesthat size will work 100% perfectly, as it is the exact same diameter as the 225/75-16. 235/70-16 is actually a shorter tire.
What number is the height of a tire?
The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire’s width. The bigger the aspect ratio, the bigger the tire’s sidewall will be.
What’s the difference between 265 and 285 tires?
The larger 285/70R17 tire in the photo above stands over an inch taller and is nearly an inch wider than the 265/70R17 size. The width of the tread is also a half-inch wider. Many late-model domestic trucks accept this difference in size.
Are wider tires better?
From a safety point of view, both types have their good sides: On a dry road, wider tires will offer more grip than narrow ones, but the risk of aquaplaning will be higher with wide tires. – In the winter, narrow tires are better under extreme conditions as they provide higher surface pressure against the road.
Are 285 tires the same as 33?
285/75/16 is the metric equivalent of a 33″ tire. Although the 285/75/16 is usually the accepted metric size for 33’s, the actual diameter of the tire varies from manufacturer to manufacturer. 285’s actually vary in true diameter. Meaning some are smaller than 33″ and some are larger.
What is the difference between a 60 and a 65 tire?
The 65% aspect ratio (as in 235/65/17), compared to 60%, adds almost 12 mm (1/2″) to the radius of the tire (0.65-0.60)*(235mm)=11.75mm.
What is the difference between 60 and 70 series tires?
The series is a % of the sidewall compaired to the width. A 70 series tire sidewall height is 70 % of the tires tread width, a 60 series tire has a sidewall hight of 60% of the tires tread width.
What is the difference between a 65 and a 70 tire?
The series number in a tire-numbering system refers to the aspect ratio of the tire’s sidewall height to its width. A series 65 tire’s height is 65 percent of its width, a series 70 tire’s height is 70 percent of its width and so on.
What does the Z mean on tires?
A “Z” rating can mean different things. While it nearly always means a high performance tire for high-performing sports cars, “Z” may actually appear in the middle of a tire’s size information. When it does, it represents either a maximum speed of more than 149 mph (240 kph) or 186 mph (300 kph).
How tall is a 17 inch tire?
|17 INCH TIRES||TIRE HEIGHT|
|225 35 17||23.20|
|245 35 17||23.75|
|315 35 17||25.68|
|335 35 17||26.23|
Should I get H or T rated tires?
Tires with higher speed ratings generally have better steering response and cornering grip than lower-speed rated tires, in addition to being capable of higher speeds. So if your car originally came with H–rated tires, that’s what you should replace them with. Sticking with H–rated tires comes at a cost.
