how much of a difference in circumference will throw off the ABS light? Some of you are running big n' littles and rim/tire combos that have different size front and rear tires, does it throw on your ABS inop light? I am just curious, as I am going to be running 295/30/18's on the back and 265/35/18's on the front (a circumference difference of roughly 1.3%) on my 10.5 and 9.5 inch wide rims. I know most of you with 10.5 and 9.5 inch wide rims are running 295/35/18's and 275/35/18's, which is a circumference difference of around 2.1%

Incorrect . . . is the OD of the tire is inexcess of 1/2" the ABS will not be happy.

in my situation, there is a difference of around 3/10" from front to rear.
for those of you that are running 295/35/18 rears and 275/35/18 fronts, you are right around a 1/2" difference in radius.....is your ABS happy??

I have driven the car fairly hard at a road coarse and ran inot no issues . . .
But I have been warned that there could be an issue during a panic stop . . .

I asked this last week---apparently 1/2 " is about the safest difference between fr-back so as not to disturb the abs...there are abs delete kits available for 125$ or so.
