I'm replacing the tires on my car and ran into a problem.
I'm going with Pirelli PZero (not run flats)
On the back I'm using 355 30 ZR19.
On the front I can only find 285 35 R18. I thing that I can get by with running a little wider tire but don't know what the difference is between the R and ZR tires.
Will I run into any problems running the R type tire on the front and the ZR on the back?
(I only drive on the street.)
