Hi all,
Had a blow out on the back end last night, no damage to the car.
Decided to just grab some part worns this morning and put a pair on the back. These are non run flat and are 225/45/17 rather than 225/55/17 that was on before. A set of run flat 55's are still on the front.
As a result, I'm hit with faults on iDrive. Parking brake failure, pedestrian protection system, flat tyre monitor, brake system (all amber) and a red restraint system warning, loss of power, TC light when gently applying power, tight steering, loss of speedo.
I can only assume this is just the car noticing the difference between the front and rear size difference.
I can either take these tyres back and have 55's put back on, or I can (and would prefer to) put 45's on the front as they look better.
Can anyone see this being a problem and is this the likely error of the faults? If I deactivate the DSC traction control I suffer no errors.
