What happened to my tire?????
I just recently purchased a high mileage 1998 gs300 from an auction. When I drove it home I noticed the front of the car was vibration and has this rumble noise once I hit above 18mph. I also notice when I brake it also vibrates as it slows down. My first thought was this could be the rotors, or the sound is just from crappy tires. Long story short I had some spare rims sitting around the house, so I decided to swap the two front wheels out in case it was the tires. When I pulled out the front left wheel I noticed that inside of the tire was all jacked up. Ive seen worn tires before, but this was totally jacked up. The wear is like someone took a knife a carve into the tire. No wonder why the car was vibrating, it was unbalanced. The outside wall of this tire is perfect. The front right tire is perfect. Nothing is wrong with it.
My questions is...what happened for my front left tire? If its camber issue or alignment, then wouldnt the wear be evenly smooth? How can only the front left tire be soo jacked from the inside wall?
Lastly after changing the wheels the car rides super smooth. It drives straight as well.

Sounds like what is known as cupping. This is usually caused by alignment and/or shock/strut issues in my experience. Other things like balance and bearings are listed are possible causes too.
Parts America Explanation:
Cupping can be caused by an unbalanced tire condition, faulty wheel bearings, loose parts, fatigued springs or weak shock absorbers. Check the condition of the shock by forcefully bouncing the front end of the car several times and releasing it on the down stroke. Failure of the vehicle to settle after two strokes suggests worn shocks or struts.

Cupping, also called dipping or scalloping, is most common on the front tires of a vehicle. This problem may be a sign that your wheels are out of balance, or that suspension or steering system parts are worn out.
