Tyre question

[limoncello]

i have on my car 235 55ZR17 99Y 's im searching the tyre online sites and most dont seem to have the facility to add the Z in the search, what does this Z mean, and can i get tyres that dont have the Z ?

ZR+ Symbol "Y"

Tyres marked with both designations for vehicles with speed capability over 240 Km/h but not exceeding 300 Km/h

[limoncello]

so i MUST have it, or is ok if i dont go over 140 mph

W/Y/Z are pretty much the same for most road cars and a lot of tyre sites mix them in their searches.

Thats why im confused, most dont even have the zr option and Y is faster than zr anyway.
