Can I get some tired advice?

Personal experience, a 140 cobra front and 240/55 rear will NOT impede the ABs system, it still works, I use mine all the time.

Will this combination give me a fault code for the ABS? Looking at the chart that one of the members posted about this it states that the OEM is -3.9%, and with the combination mentioned above the difference is 2.2%. So that would be a 6.1% and it states that the ABS will fault at 6%.
Just doing some homework as I will be needing new rubber soon, and was looking into some alternate combinations also. I was originally looking at the 140/80R17 up front OR the ExedraMax on the rear but had not considered changing both due to the ABS??

No that combo will work fine with abs.
BTW it's 140/75r17
