Default Different Diameter Tires and ABSINOP

Ok, recently I had to replace one of my rear tires. Well the tire I replaced it with is new, and it is taller than all the others The current ones have bout 20k miles on them so they arent that good anymore. Since it is in the rear, will it be enough to throw off my abs? I reset the computer it and it goes away but then I get the low trac light on a few times then the absinop light will stay on. I already had the 2 speed sensors up front replaced. I guess I'm goin to patch up the old tire and see if that works. Any comments help..............

you should have the same tires on both sides or else you can mess up the gears in the differential.

how will it mess it up? brad8266
The tires on it are 285/40 17, but like I said one of the rear ones is new so its taller than the rest.

It burns up the rearend with 2 different sized tires because they are turning at different speeds. The smaller tire turns faster than the taller tire. If you have the same rims/tires all the way around you can put the taller tire on the front untill you get matching tires. At least thats what I would do.

Ok I hear what you guys are saying, but keep in mind both tires are 285/40 but one is new the other is not. BTW I never knew and no one told me any different at the tire shop........argh.... anyway I guess I'm goin to swap it out asap.

If you had a single track rearend it wouldnt matter as much. But with a limited slip it could happen. Its not going to happen over night unless you ran the crap out of it. But over time it will ruin your rear.
