Hi All,

I just replaced the tyres on the X5 E70 I just bought, and now the DSC and 4X4 are coming up with errors.

The tyres I bought were

235/55 R19 front
and 285/45 R19 rear.

After fitting them I found out the fronts should be 255/50 R19s.

Would this make enough difference to the DSC system to throw an error?

When I bought the car, it had 235/55 on the front, and on the back it had odd tyres - 285/24 on one side and 255/50 on the other!

There is a .2% difference between the diameter and circumference of the two tyres.

DSC & 4X4 were fine before the tyre change.

Cheers,

JG
