• Many tires wear out prematurely because of lack of alignment knowledge.stack of old tires image by JoLin from Fotolia.com
  
  There are two main types of alignments, thrust angle and four-wheel alignment. Your 2007 Honda Civic requires a four-wheel alignment. There are three angles that can be adjusted on a vehicle: camber, caster and toe. The Honda Civic only has two angles that are adjustable without aftermarket parts, toe and camber. When looking from the front of the vehicle, camber is the positive or negative angle that the tires lean. Toe is the direction the tires are pointed from under the vehicle.
  
  

Pulling

• When your Honda begins to pull or drift to one direction when traveling on a flat surface, it can be either camber or toe causing the problem. If the wheels are pointed too far in one direction due to excessive toe angle, then the car will pull in that direction. If the camber is out in a positive angle on one side and a negative angle on the other side, it can also cause a pull to one side.
  
  

Edge Wear

• Edge wear of a tire is when the farthest outside point of the tire wears in excess of 2/32 inch more than the rest of the tire. This uneven wear is caused by the camber being out on the vehicle. Camber causes the tire to bear more weight on one side of the tire than the other and that causes the extra wear. This type of wear can happen on either side of the tire; it depends on if the angle is too far positive or negative. This can also be caused by worn-out ball joints on your Honda Civic.
  
  

Feathering

• Feathering is when the tire tread develops an angular wear pattern. This means that one side of an individual tread block is low and rounded, and the other side is high and sharp. This feathering is caused by the dragging of the tire from a bad toe adjustment. This wear pattern may also be caused by loose wheel bearings.
