A few months ago I had to get front tires to pass inspection. I didn't have enough money for new tires so i bought 2 used ones. After leaving the lot, I noticed sort of a humming sound out of my right front. It starts at about 30 mph and gets worse until I get to about 45 and then starts getting less at higher speeds. It seems as if it gets louder when I slow down so I thought it was a brake issue since my pads were getting thin. Over time I noticed that the front right tire loses air and that the sound gets better when I inflate the tires again.

After about 2 months my ABS light started coming on, and stays on. About 95% of the time the light comes on right when i start the car, but the other 5% it comes on after about 10 miles or so. I thought the two were related.

Today I replaced my brake pads and resurfaced my rotors. The sound is still there, and i'm completely lost. I've read that the ABS light is probably a bad sensor, but I just thought it was odd that I started having the problem shortly after this sound started.

Please help me! I'm broke as hell, and can't afford to take my car in right now unless it's absolutely necessary. Maybe someone can help me pinpoint the problem without taking it in.

oh, and it's a 2002 GT with 136k miles on it. Never had any problems with it before.
