Does it pull to the side? It may be your tires. Bad tires. Flat spot on the front tires. Try to rotate your tires. And see what happeneds.
Why? To even out tire wear. The front tires will wear much quicker than the rears on a FWD vehicle. The front tires are pulling the vehicle and are also steering the vehicle. This causes friction which causes wear. You rotate by simply putting the rear tires on the front and the front tires on the rear every 10,000 miles. Click the link and go to Tire Rotation.
"Scalloping" is usually caused by bad struts. But, could also be from inproper alignment, lack of tire rotations (matinence, not motion), or even poor quality tires. I've known many people with Toyo tires that have this problem.
