wheel aligment or ball joints Lack of rotation and hard cornering.
Poor tire alignment will cause wearing on the inside edges of rear and even front tires.
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.
Have the alignment checked at a local automotive shop.
Usually a suspension or front end proble causes uneven wear on the tires and you get noise from them, similar to running on snow tires
The wheel alignment is off, probably the camber.
Wear in the front end components, and or, (excessive stress) caused by the wrong size tires, or different sized tires, and or, front end damage from an accident of some type.
Only on a front wheel drive vehicle. On a rear wheel drive the rear tires wear faster. rotate your tires every 10,000 miles and they will wear evenly.
Because they are used for steering and get more wear.
Normal wear.
Overinflation.
Misaligned axles, bad mounts on the tires, improperly inflated tires.
The bearing or the bearing shaft of the front wheels are not aligned and the wheel balance alos could be a reason that tends to wear out the front tires.
