No, what would cause it though is the oversize tires tricking the computer into thinking it is going faster than it actually is and trying to lock the converter. I would get with waitformeperformance and have a custom tune done on it to calibrate it for your tire size among a host of other things he can do to improve performance, if you send him your computer it will cost a whopping $75 and be the best money you ever spent!
As far as your abs goes find a shop with a abs scanner and see what it reads, bet the farm it is a front wheel hub assembly!
