Question: What does the 70 mean on a tire?

Tire width always refers to the measurement from one sidewall to another. Tire makers calculate the aspect ratio by dividing a tires height off the rim by its width. If a tire has an aspect ratio of 70, it means the tires height is 70% of its 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 tires sidewall height to its width. A series 65 tires height is 65 percent of its width, a series 70 tires height is 70 percent of its width and so on.

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 tires width. The bigger the aspect ratio, the bigger the tires sidewall will be.

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.

Is a 65 or 70 tire taller?

The main thing is that the 70 is a little taller than the 65, width is the same.

What tire is wider 60 or 70?

The 215 designation would be the amount of weight the tire can carry at a given tire pressure.

What is the difference between 265 70 and 265 75?

For the 16 rims, 265/70 is the stock size. Going from 265/70 to 265/75 is increasing the height, or diameter, of the tire. The tire will be an inch taller. 265 is the width, so stock size is 265 millimeters wide.

How far off is my odometer with bigger tires?

1/8” tread wear on a 36-inch tire reduces the circumference by 0.8 inches. Over the length of 1 mile, this adds up to 33.6 feet. After “actually” traveling 157 miles, the odometer will be “off” by 1 mile. It will read 158 miles.

Whats better 17 or 18 inch wheels?

While larger-diameter wheels and tires should improve handling and high-speed performance, lower-profile tires also tend to have a firmer ride and may be noisier than the smaller, standard rubber. An 18-inch tire, for example, will probably weigh at least a couple of pounds more than a 16- or 17-inch tire.

How much taller is a 70 tire than a 60?

How much taller is a 65 tire than a 60?

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.

Whats the biggest tire I can put on a 15 inch rim?

To increase performance, your tire should be compatible with your rim size. 33-inch tires work well with rims that measure 15 or 16 inches in width, while 35-inch tires should only be used with rims that are at least 17-inches wide.

Whats the difference between a 225 tire and a 215 tire?

The 215 tires will provide less grip than the 225 tires due to their different widths. With an increased grip on the road surface, the 225 tires will achieve greater levels of shorter braking distances while increasing traction, especially on wet surfaces.
