Hi, i have a 2000 2.0 Zetec, the TC light keeps coming on and off intermittently. Had the ecu read and no codes have been flagged up. I have noticed though the 2 front tyres are 205/45/16 and the rears are 205/55/16, will this make a difference to the TC or is it ok as long as the 2 tyres on the same axle are the same size? Thanks for any help, Ade.
