Guys, according to a tire size calculator, the percentage difference between my two tires is 2.7%

can this much difference trigger ABS under moderate/hard braking?

tires are 245/40/18 front and 305/35/18 rear

i used to run same fronts but with a 275/35/18 rears which is only a 0.5% difference, and I feel like now with the 305's, the ABS is coming in a lot sooner.

I believe its +/- 2 inches in height that will affect the abs

i'm having the same issue, i switched from 275/35/17's up front to 245/40/17's and kept my 315/35/17's in the back, now when hard braking the abs comes on alot sooner.......
