This came from Michelin when i asked about fitting 255/50 r19 Hi Tony, The fitment should be OK The OD doesnt change by more than 15mm, which is the max allowable change in OD by vicroads However, this will put the speedo out by -1.93% I dont believe we have a 255/50R19 107V in Latitude sport, we have 4x4 Diamaris and Latitude tour hp. I would go with the 235/50R19 107V Latitude Tour HP (CAI 177914) _____________________________________________ Welcome to the world of limited, super expensive tyre options
