Default tire size question

picking up some new tires this week or next, I am going to run 315/30/18 toyo r888s on the rear, what size do i need to run on the front to keep the traction control from freaking out

I searched for it but couldnt find exactly what i was looking for, all i could remember was seeing that the rear was supposed to be like .75 to 1.5 inches bigger in diameter than the front but i dont remember if that was right or not

You want the rears to be .5"-.75" larger in diameter than the front or you run a real good chance at having TC issues. Some get away with as little as .4", but less than that will come back to bite you when that tread starts to wear off the rears faster than the fronts...which is pretty standard on these cars.
