You will find it at the end of the tyre's size (the list of numbers on the tyre's sidewall) always represented by a letter and usually following a number - in the following example the tyre speed rating is "V". ... Confusingly, W-rated tyres are rated at a higher speed in excess of 168mph.

Tyre speed rating is the maximum speed that the tyre is legally approved to be driven at, based on the recommended load index that's also on your tyre. These speed ratings are based on practical tests that engineers run when new tyres are designed – making sure the tyres can safely reach high speeds.

Even though the H is limited at 130 mph and the national speed limit is 70 mph. ... The speed rating itself is the maximum speed a tyre can travel, for example, the V rated indicates that this tyre can travel up to 149 mph. The table below shows what each letter is rated at.

Identification. H-rated tires are rated for a maximum speed of 130 mph. The V rating is the next rating faster, and V-rated tires are good to 149 mph. Both H- and V-rated tires are considered to be performance-touring tires.

The 55 and 68 are load ratings. The W is the max speed rating. So both have the same speed rating.

The volt-ampere is dimensionally equivalent to the watt (in SI units, 1 V⋅A = 1 N⋅m⋅A−1⋅s−1⋅A = 1 N⋅m⋅s−1 = 1 J⋅s−1 = 1 W). VA rating is most useful in rating wires and switches (and other power handling equipment) for inductive loads. With a purely resistive load, the apparent power is equal to the real power.

20W40 is a commonly used motor oil grade. ... The letter W indicates winter and at last the number “40” stands for the viscosity of oil when the engine is operating or hot. In simple terms viscosity means the thickness of the liquid, here oil. Higher the number, thicker is the liquid and therefore harder to flow.

Viscosity This term is defined as how well the liquid will flow through the engine. The working viscosity of 5w30 is basically from 9.3 to 12.5mm2/s whereas the operating viscosity of 5w40 is 12.5 to 16.3mm2/s. That means 5w40 has larger viscosity than 5w30. So, 5w30 is better than 5w40.

In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft. These speeds are derived from data obtained by aircraft designers and manufacturers during flight testing for aircraft type-certification testing.

The tire speed rating is the maximum speed tires can safely carry a load (the original weight of your vehicle plus whatever's in it) for a sustained amount of time in ideal conditions. The rating is molded on the tire sidewall, signified by a letter or two, usually after the load index number.

Understanding Tires Load Index VS Load Range. The numbers you see on the sidewall of a tire, contain valuable details about the tire. ... A speed rating will be an alphabetic number ranging from L-Z stating how fast the tire is rated for. Load Index will be numeric and will run from 0 - 150.
