“65” in the sequence is the aspect ratio of the tire. The aspect ratio is a percentage, and it tells you the ratio of the tire’s height to its width. In this example, the aspect ratio number “65” means that the tire’s height is 65 percent of its width .
How wide is a 65 tire?
It’s the height of the sidewall measured from wheel rim to top of the tread, expressed as a percentage of tire width. In this example, the aspect ratio is 65, meaning the sidewall is 65 percent as high as the tire is wide. To get the sidewall height, take the tire width of 215 mm and convert it to inches (8.46).
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.
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 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.
Do bigger tires affect gas mileage?
For example, larger tires decrease your fuel economy because they are heavier , while smaller tires increase fuel efficiency. ... Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.
What is the difference between a 70 and a 75 tire?
I think the 75 series tire is roughly 1′′ taller than the 70 series .... so 1/2′′ more sidewall... not a lot of difference. The 75 definately “looks” better and might even get ya better mileage as you’re not turning as fast....
How much taller is a 70 tire than a 60?
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.
Are 285 tires the same as 33?
YES, 285 wide tires are the same as 33” tires although 285 is the tread width in millimeters and 33′′ is the tire diameter. 285/75/16 is usually the accepted metric equivalent size for 33’s.
Are 295 tires the same as 33?
You are correct. The 295 is a true 33 , the 33×12. 5 is just over 32′′ mounted.
What does the 60 mean 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. R stands for radial construction.
What’s the difference between 225 60 r17 and 225 65 r17?
Yes, the heavier 65s will be more weight per corner and therefore will reduce gas mileage and acceleration slightly, and the speedo will be slightly off. The main advantages are a cushier, softer, smoother ride with more “suspension”/air cushion in the tire sidewall height.
What tire numbers stand for?
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.
Can I put 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 wheels...the aspect ratio (height of the tire) decreases to compensate...and maintain the orig diameter/circumference.
Are 55 or 60 tires wider?
*Going from a 60 to a 55 series, SAME Width . IF width is increased on the 55, ratio /revs per mile will decrease.
How much taller is a 235 tire than a 215?
The tire size is the width in millimeters from the edge of one sidewall to the edge of the other sidewall. Therefore, a 235 tire is 20 millimeters wider than a 215 tire .
