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.
