A speed rating of H indicates that a tire is rated for a maximum speed of 130 mph (210 km/h). This rating is part of a standardized system used to signify the tire's capability to safely perform at certain speeds. Tires with an H rating are typically suitable for performance vehicles and some sedans that require higher speed handling. Always ensure that tires match the vehicle manufacturer's specifications for safety and performance.
Steel Radial Speed Rating
If one's speed changes from 10 km/h to 6 km/h, one has decelerated.
take different speed while you travels... then add it.... Divide it with number of speed taken.... eg: ( 60km\h 62km\h 69km\h 63km\h ..... then (60+62+69+63)/4 )
2.45km/h
That depends upon the speed of sound through the medium in which the speed is being measured. mach = speed ÷ speed_of_sound_there ⇒ speed = mach x speed_of_sound_there In dry air at 20oC the speed of sound is [approx] 1236 km/h ⇒ speed_of_mach_0.85 = 0.85 x 1236 km/h ≈ 1051 km/h At 11,000m (where the air temperature is about -50oC) the speed of sound is approx 86% of that in air at 20oC, that is about 1063 km/h ⇒ speed_of_mach_0.85 ≈ 0.85 x 1063 km/h ≈ 904 km/h
H speed rating is 130 mph maximum.
The H is the speed rating. The H rating means the tire has a speed rating of up to 130 mph. http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=35

It's a speed rating, in this case meaning 'up to 130 mph'.
That is the speed rating of the tire. H is rated up to 130 mph.
A "T" speed rating means the tire was tested to withstand at least a constant 118 mph....... An "H" rating 130.
The 99 is the load rating and the H is the speed rating. The higher the load number the more weight the tire can carry. The speed number H means it is rated to 130 mph.
The 99 is the load rating and the H is the speed rating. The higher the load number the more weight the tire can carry. The speed number H means it is rated to 130 mph.
It is the maximum speed your tire is made for. It is indicated by the last letter on the tire designation. - eg, 215 65 R15 95 H - the H is speed rating.
Tread is 195 mm wide. Sidewall is 60 percent of 195 mm tall. R is radial tire. 15 inch rim. H speed rating.
The 'Q' rating on the tyre represents the speed rating and any tyres that come with a 'Q' speed rating means that the manufacturer recommends a maximum speed of 99mph.
