    Has anyone ever fitted 355/30ZR19 to a 360 or 430?

    I am trying to finalize a deal on a set of Novitec NF2 wheels from a very nice forum member and we are chatting about what tires work for the rear wheel. The original spec Pirelli are NLA and the 345/30 19s are impossible to find.

    Has anyone fitted at 355/30ZR19 tire on a 360 or 430? Specifically looking for feedback on a Michelin Pilot Sport 4s but curious if ANY brand in that size has successfully been installed on a 360 or 430.

    Thanks in advance.

    tires for those rims are a problem

    beautiful rims but the tire issue is a major concern

    I have 345/30/19 on my NF 2"s. The car has been lowered with Novitec coil overs so it is pretty low. 355's should be fine with stock ride height. I have MPSS on mine

    abt 15 years ago when the NF2's were really new and hot there were no tires.+

    I knew of someone who had a sidewall fail on a rear tire and he could not drive his car for 6+ months due to lack of tires

    beautiful wheels for sure though

    Pirelli's last run of the 355/25 19 tires designed for the NF2 was in 2008. After that it was MPSS in 345/30 19 and now it looks like it will be MPS4S in 355/30 19. My 575M had NF2s for a spell and it was always a pain finding tires. I bought a set of NF1s (cannot be fitted to a 575M, I discovered) and someone had stretched much smaller tires onto the rears. Must have ridden like a truck with the sidewalls spread like that.

    with the MPS4S 355/30-19 will throw the speedo off a bit

    The speedometers read fast at any rate. May help.

    actually the difference is not too bad

    this may actually correct the factory fast speedo error
