Rear tire of motorcycle Diablo Supercorsa Sp-v4 of the company Pirelli. It is suitable for on-road driving, meaning it can only be used on the road (asphalt).

Its dimensions are 190/50-17. That is, it has a width of 190mm, a profile of 50, and can be mounted on a 17" rim. The profile in tires, meaning the height of the tire's sidewall, is always referred to as a clean number without a unit of measurement as it is a percentage of the width. For example, a 180/55 tire has a width of 180mm and a profile of 55, meaning it has a profile of 180 x 0.55 = 99mm.

The TT marking comes from the initials of the words Tube Tyres. Tires bearing this marking require an inner tube.
