    Hi All,

    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.)

    Thanks,
    Scott

    I think youre missing the actual speed rating, W or Y coding for those tires. Example 275/35ZR18 (99Y) XL or 345/30ZR19 (109Y) XL.

    Where are you getting the Pirellis? Tire Rack only shows the Michelin Pilot SS's in those sizes.

    The speed rating is Y97 for both. I've had the rear tires for awhile. I'm getting the front tires from the Tire Rack. (285 35 R18)

    No offense to Grant , as he did a good job, but for those of you who call Tire Rack for Viper Tire Questions, your best bet is Extention #4362 , Luke Pavlik. Years ago they sponsored the site and Luke would show up at major Viper events. He knows our cars better than anyone in the tire business in my estimation, so put him on your list to call if you contact Tire Rack.

    Chatted with Luke yesterday and he mentioned there should be a few tires incoming. Would call him as suggested above and see if you can reserve some? Hopefully I understood him correctly?

    Hard to get Pirellis now , and Michelin Super Sports seem to be on hand in very workable sizes -- 1-888-981-3953 , ext. 4362 for Luke Pavlik . He has been helping folk on this site since the 90s and is a fellow track rat!!
