Quick question.
I have Pirelli P - Zero Nero's on my sti.
need to replace the front two and notice that they are 225/40/ZR18 (92Y), whereas the back two are 225/40/R18 (92Y).
Is there any difference between the two (I'm guessing not but thought I'd ask anyway
)
Cheers

it's the 'y' in brackets that indicates 'tested in excess of' 186mph. Z just means in excess of 149mph. the R simply means radial... the 92 before the 'y' indactes a load index of 1389lbs.
