Quick responce needed (need to order): Difference between ZR and R rated tyres??

[DJM1982]

Need to order 4 new tyres for my A4.
Been looking on Camskills and found some uniroyal rainsports that i would like to buy. But they are 235/40 R18, Y rated not 235/40 ZR18 Y rated like the Michelin Pilot Sports that are on the car ATM.

Whats the difference and is it ok to fot these to my car?

I tried ringing Camskills for their advice but they are shut for the night?

cheers, if i'm reading correctly then they should be fine on the A4 because they are (95Y) rated.
I'll get some ordered shortly i think.

Careful, if you don't get the correct speed rating (manufacturer recommended), your insurance will be invalid. I'd ring a local tyre place and ask what should be fitted or search the interweb.
