What do the 3 sets of numbers on a tire mean?

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. This may also be referred to as the section width. In this example, the aspect ratio is 65, meaning the sidewall is 65 percent as high as the tire is wide.

What’s the difference between 60 and 65 on tires?

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.

Which tire is wider a 65 or 70?

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. These differences in height affect both performance and safety issues while driving.

What is the 60 in tire size?

60 is the two-figure aspect ratio. This percentage compares the tire’s section height with the tire’s section width. For example, this aspect ratio of 60 means that the tire’s section height is 60% of the tire’s section width. R indicates the construction used within the tires casing.

Can I use 55 tires instead of 60?

Yes the wheel/tire combo has an overall diameter/circumference that should be maintained with 3% (+/-) the original spec. When you plus size wheelsthe aspect ratio (height of the tire) decreases to compensateand maintain the orig diameter/circumference.

Are wider tires better?

Larger tires improve handling and cornering, due to wider tread faces and stiffer sidewalls. Wider tires may also increase acceleration, especially in very powerful vehicles such as muscle cars. Larger wheels with lower profile tires are sometimes aesthetically desirable.
