P identifies your tire as a Passenger Tire. R indicates the construction used within the tires casing. R stands for radial construction. B means belted bias and D stands for diagonal bias construction. 17 The last dimension listed in the size is the diameter of the wheel rim, which is most often measured in inches.
Does the R in tire size matter?
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. If a tire size reads, LT235/75R15 104/101S, the LT indicates that this tire is meant for Light Truck use.
Does R in tire mean radial?
When a letter (R, D, or B) follows the two-digit aspect ratio, it tells us the tire’s construction. In this example, the R means that the tire has radial construction. Over 98% of all tires sold today are radial tires, where the internal body plies of the tire radiate outward from the center.
What does R18 mean on tires?
Size of the Wheel It Fits When it says R18, it means that it has a radial-ply construction and it fits an 18-inch rim. A tire can only be installed on a wheel that is identical to its inner diameter.
What does 55 R mean on a tire?
In our example, the 55 means that the sidewall height is 55% of the 205-mm tread width. Construction. The letter following the profile height identifies the tire’s construction. Most tires sold today are an R, which means they are of radial tire construction.
Can I use 55 tires instead of 65?
The 55 is the “height” of the tire. Generally not recommended as the new tire is about 6% smaller than the older one. From a strictly ‘will it fit’ stand point, yes. 205 is the height, the 55 is slightly wider than the 65 (it’s a ratio); and the 16 is the rim diameter.
Can I put 60 tires instead of 55?
Most likely yes. The 55 or 60 in this case is the aspect ratio. It’s how tall the tire is as a percentage of its width. A 60 means the tire’s sidewall height is 60% of the width of the tire.
Will a 65 tire fit a 60?
Yes, the only real difference is that ratio between the tread width and the height of the sidewall will change. The lower the middle number the lower the profile of the tire the larger the number the higher the tire profile.
What is the 275 on tires?
The numbers in the tire size refer to its width, aspect ratio, and wheel diameter. “275/35R19″ means the tire is 275 mm wide, has an aspect ratio (that is, the width divided by the height) of 35%, and fits on a 19” wheel.
How do you read a tire rating?
The first two digits (87S) represent the tire’s load index and are followed by a single letter (87S) identifying the tire’s speed rating. “Using a P195/60R15 87S tire size as our example, the 87S at the end of the size represents the tire’s service description.
What does 50r mean on tires?
50 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 50 means that the tire’s section height is 50% of the tire’s section width. R indicates the construction used within the tires casing. R stands for radial construction.
What is the difference between a 60 and 65 series 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.
Can I use 245 tires instead of 235?
So you have already identified the difference between 235 and 245 size tires. It is obvious that 245 is bigger than 235, still, both tires’ sizes are pretty common and could be interchangeable at times.
What does 55R16 mean?
55. This number means that your tire has an aspect ratio of 55%. In other words, your tire’s sidewall height (from the edge of the rim to the tire’s tread) is 55% of the width. In this case, the sidewall height works out to be 112 millimeters. R.
What size is 205 55R16?
205/55R16 tires are 24.9″ tall, have a section width of 8.1″, and fit wheels with a diameter of 16. The circumference is 78.1″ that translates into 811 revolutions per mile. As a rule, they can be mounted on the wheels with 16″ x 5.5-7.5″ rim width.
What does 205 55R16 mean on a tire?
Using our example size, 205/55 R16, this is what each number means: 205 is the width of the tyre tread in millimetres. 55 refers to the profile of the tyre, or the distance between the wheel and the edge of the tyre, looking at it from the side. The number is the percentage of the width of the tyre.
Which tire is wider 45 or 50?
got that 1 wrong, the 45 and 50 is a percentage of the width, so the difference between 45 and 50 profiles is 5% of the width.
Can you put 205 55R16 tires?
Yes it will be completely fine, in fact 205/55/16 are the most common 16″ tires.
What is the difference between 215 55R16 and 205 55R16?
It’s possible the slight size difference would cause the tires to rub on the fender, but that’s unlikely, as the difference is small, and you rarely use all the suspension travel. The width of the tire 205/55R16 is 10 mm narrower than the 215/55R16, they are OK, it wouldn’t cause any problem.
