What size is a 195 65R15 tire in inches?
R15 tires have a diameter of 25 (635 mm), a tread width of 7. The sidewall of the tire is 5 (127 mm), and the tire’s circumference is 78. For example, 205 means that your tyre is nominally 205 mm wide. The second number is the relationship between a tyre’s sidewall height and the tyre’s width. It is expressed as a percentage. For example, 55 indicates that the sidewall height, between the top of the tread and the rim, is 55% of the tyre width.R represents the carcass construction (radial) 17 is the wheel diameter (inches) 105 is the load index.This is also known as the aspect ratio. The lower the number, the more ‘low-profile’ the tyre.
What does 195 65 R15 91H mean?
Using a 195/65R15 91H tyre size as our example, the first part – 195 – corresponds to the width of the tyre. This is an aspect ratio against the next number, 65 – which relates to the sidewall, or profile, of the tyre. The next part – R15 (or ZR15) is the diameter of the wheel that the tyre is for. A 60 tire will have a lower profile compared to a 70 tire, meaning the sidewall height is shorter. This lower profile translates to enhanced handling and responsiveness on the road. On the other hand, a 70 tire offers a higher sidewall, resulting in a more comfortable and smooth ride.These numbers show the aspect ratio, which is the tire sidewall height in percentage to width of the tire. The width of Sidewall is directly proportional to the aspect ratio, a 70 aspect ratio means the sidewall height is 70% of 265mm while 65 aspect ratio means it is 65% of 265mm.
What is the speed limit on a 195 65 R15 tyre?
It has a load index of 91 and the maximum load it can handle is 2460 Kgs. Speed rating of this tyre is T which means the maximum speed limit this tyre can support is 190 km/ph. D Load Range Tires This load range can hold between 2,000 and 2,500 pounds of trailer weight per tire with the tires’ pressure being 65 psi.
