Engine Drag Control
I did a little research but came up with nothing especially when it comes ty tire size. I'm running 305/35/19 mt et streets on my rear wheels so what size front tires would I need to go with to avoid this light from coming on? I need help ASAP so it's much appreciated. Thanks.

my stock sizes are..
275/35/18 (25.57" dia)
325/30/19 (26.67" dia)
total is 1.1" larger dia. rear. what car expects.
yours...
305/35/19 (27.4")
265/40/18 would be 26.3" , probably other sizes that would be 26.3"
305/30/19 would be 26.3"
325/35/18 would be 26.41"
you didnt say if fronts are 18", i assume they are. you need to find a size in total diameter that is 1.1" less (26.3") for the fronts. (or very very near that) note, i just did a tire size calculation, i never verified that mt's are 27.4", you should verify.

"Drag Control" is a deceleration traction control that helps to keep the rear wheels from locking under severe deceleration. Tire size mismatch can cause the light but it should happen only under extreme deceleration (downshift from 6th to 4th @ high speed).
