What does 95H mean on a tire?
H”, Explained The load index (“95” in this instance) tells you about how much weight the tire can support when it’s properly inflated. This can range from 75-105 for passenger vehicles. H” represents the speed rating, which is how fast the tire can safely go based on its load capacity. T and 102H are service descriptions. Load Index, what this means is, the tire is capable of carrying weight up to, 1,874 lbs per tire. The T and H are speed Ratings, this indicates that a tire is capable of speeds up to, 118 mph and 130 mph (respectively).Tire speed ratings are generally listed on the tire sidewall alongside other important information like tire size and load index. For example, a tire marked with “P225/60R16 95H” has a speed rating of “H,” which corresponds to a maximum speed of 130 mph (210 km/h).Using the above example, you would also see ’99H’ on the tire sidewall. H is the speed rating that tells you the maximum service speed for a tire.Understanding Tire Load Indexes: Load indexes go up to 279, but for most passenger car tires, it is in the range of 75 to 105 (although some can handle even more! So, let’s take an example: a tire with the size of 235/55R17 99H has a load index of 99, meaning it can carry a load of 1,709 pounds.A higher rating should not be a problem, but going lower than you need is a risk.
What does 55R18 mean on a tire?
The second two-digit number 55 refers to the ratio between the height of the sidewall and the width of the tire. R stands for “Radial” and the last two figures 18 indicate the wheel diameter in inches. Section width in millimeters, 55 is aspect ratio, means the sidewall height is 55% of 215(Section width), R is for Radial, 17 is Rim diameter in inches and 94 is load Index(1477 Lbs per tire load carrying capability) and V is speed symbol ( 240/hr or 149mph).R – The ‘R’ in this construction indicates radial tyre construction, almost every new tyre built today is a radial tyre. This indicates the wheel diameter which is measured in inches.R16 95V 215, or the first 3 numbers, represents the width in this tyre size reading, measured in millimetres. R16, the numbers in this portion, is the diameter of the wheel rim in inches.The letter H on a tyre indicates that it is rated for a maximum speed of 130mph. The letter T on a tyre indicates that it is rated for a maximum speed of 118mph.The speed rating is typically the last letter listed on the sidewall (coming after the load index, which is a number). For example, if you see “M+S 235/45 R18 94V” on the side of the tire, the last letter, V, is your speed rating.
What is the tire pressure for 215 55R18?
R18 is a Metric tire that comes in a Standard Load (SL) range and an Extra Load (XL) range. Standard load (SL) size has a load index of 95 with a maximum load capacity of 1521 lbs at 36 psi, capable of supporting up to 1521 pounds when inflated to its maximum air pressure of 36 pounds per square inch. R18 Tire Size Explanation A 55-aspect ratio means that the tire’s height is 55% of its width (in this case it is 118.The recommended tyre pressure for 225/40 R18 tyres can vary slightly based on the manufacturer and vehicle. However, a general guideline is to maintain the pressure within the range of 32 to 35 PSI (pounds per square inch).R18 is a Metric tire that comes in a Standard Load (SL) range and an Extra Load (XL) range. Standard load (SL) size has a load index of 95 with a maximum load capacity of 1521 lbs at 36 psi, capable of supporting up to 1521 pounds when inflated to its maximum air pressure of 36 pounds per square inch.Converting these measurements to inches helps in visualizing the difference more clearly. A 215 tyre converts to approximately 8. This means that the 225 tyre is slightly wider than the 215 tyre, albeit the difference may seem subtle on paper.
What is the meaning of 215 55R18?
R18 tires have a diameter of 27. The sidewall of the tire is 4. This means a 215/55R18 tire will make make 739 revolutions per mile, or 460 revolutions per kilometer. A 225/55R18 tire has a width of approximately 8. The width of the tire is the first number in the tire size designation, which in this case is “225”.The 215/55R18 95H tire has the following features: the first three digits 215 refer to the width of the tire in millimetres. The second two-digit number 55 refers to the ratio between the height of the sidewall and the width of the tire.Aspect Ratio, it is the ratio of the sidewall height to the cross section width.It is possible to use 205/55/16 tires instead of 205/60/16 tires, but in this case, the performance and driving characteristics of the vehicle may change as the width and sidewall height of the tires will be different.
Which tire is taller, 55 or 60?
The main difference between 55 sidewall and 60 sidewall tires is the difference in sidewall height. The 55 sidewall offers a lower profile, while the 60 sidewall has a higher profile. A 60 means the tire’s sidewall height is 60% of the width of the tire. Just 5% taller than the 55 tire in your example.For example, if a tire has a sidewall aspect ratio of 60, it means the sidewall height is 60% of the tire’s section width. The sidewall aspect ratio plays a crucial role in ride comfort and handling. Tires with a lower aspect ratio (e.
