What do the markings on tires mean?
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.
What does black wall tire mean?
blakwôl. Filters. Designating or of a black pneumatic tire without a colored band on the outer sidewall. adjective.
What do the letters and numbers on a tire mean?
The number is the load rating, or the amount of weight that it can handle. The letter is the speed rating, or the maximum speed the tire is built for. As an example, a tire rated 90R could safely carry 1,323 pounds and travel at 106 mph.
What does SBL mean on tires?
|RWL||RAISED WHITE LETTERS|
|RRBL||RECESSED RAISED BLACK LETTERS|
|SBL||SERRATED BLACK LETTERS|
|SRBL||SERRATED RAISED BLACK LETTERS|
Can I use 235 tires instead of 225?
Yesthat size will work 100% perfectly, as it is the exact same diameter as the 225/75-16. 235/70-16 is actually a shorter tire.
Can I use 215 tires instead of 205?
Nope. The nominal diameter of the 215’s is 1.7% greater than that of the 205’s. The sidewall height is a percentage of the width of the tire, so a 55 series is taller with a wider tire.
What does B mean on a tire?
225 identifies the tire section width, which is the measurement of the tire from sidewall to sidewall in millimeters. 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.
What does XL mean on a tire?
Reinforced or XL (Extra Load) tires are specially reinforced tires. They can carry heavier loads than tires of the same size.
Why are there no more white wall tires?
The whitewall stripe width began to diminish as an attempt to reduce the perceived height of the wheel/tire. During the decade, increasingly lower vehicle heights were in vogue. During the 1950s, Fender skirts also covered up white wall tires.
What does the last number on a tire mean?
The very last number in the sequence, “15,” is the diameter of the tire. This is an important number—this is the number you’ll refer to when you need to know your tire size! The “15” indicates that this particular tire would fit a rim with a 15-inch diameter.
What do the 3 numbers mean on tire size?
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. It’s the height of the sidewall measured from wheel rim to top of the tread, expressed as a percentage of tire width. In other words, it’s sidewall height divided by tire width.
Are wider tires better?
From a safety point of view, both types have their good sides: On a dry road, wider tires will offer more grip than narrow ones, but the risk of aquaplaning will be higher with wide tires. – In the winter, narrow tires are better under extreme conditions as they provide higher surface pressure against the road.
Why do my tires say inside and outside?
Some tires are directional which means that they have a correct direction of rotation, and some tires are asymmetrical which means they have different tread from inside to outside. Asymmetrical tires have an inside and outside to their tread.
What does R and D stand for on tires?
The D indicates that the tire is a diagonal bias ply construction and the R indicates that the tire is a radial tire construction. Beyond the size and type, there are load ranges for tires. Most trailer tires are load range B, C or D.
What is a 112t tire rating?
Referring to the tire load rating index chart below, the number 94 translates to a load-carrying capacity of 1477 pounds (per tire).
