Re: ABS light
Those Blizzaks have a dia. of 30.5"
Your Overland came with GY Fortera's 265/50/20 and those have the same dia. of 30.5"
Both are stock Jeep sizes.
Check your fuses under the hood. If you have any snow yet go find an empty parking lot and slam those brakes and see if the ABS is working or not.
Either way Blizzaks are excellent winter tires so I'd keep them on.
