What Rc tolerances means?
RC is rolling circumference. Especially on xDrive vehicles it is important that they are identical.
Having the same tires on different width rims is going to stretch/pull the tires harder on the wider rims, which may affect RC.
Should i swich to 255/40/18 in the back?
And whats the recommended tyre pressure for those dimensions?
