nankang tyres?

But remember that the ratings cover more than just speed.

A ZR tyre can support more cornering force etc. than an H tyre.

The higher the better !

The 87Y is a load index thingy - have a read of

Reading that it says that my tyres are actually Y rated. ZR17 87Y (87 = 545 kgs load) Y rating.

Interesting read, thanks :)

They're Z-Rated too !

"While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire's 168 mph, 270 km/h maximum speed"

The "Z" says they're rated to "in excess of 149 mph, 240 km/h" and the "Y" says they're rated to "Y 186 mph, 300 km/h" :)

Good innit :)
