Hello, camber a little off on the 1.3 side but 1/2 degree on the other is good. I know you have had alignment checked. There are only 3 things that can cause this. Wrong tires/wheels. Bent parts like a strut etc OR the toe is not adjusted correctly. Toe out can wear the inside edges real fast. What i do in a case like this is adjust the toe int some instead of factory specs in some to overcome the problem. described below. I am thinking the toe specs are off just enough. If each tire is pointing a little outward, the inside edges will wear real fast. .

 

WHEEL ALIGNMENT When using commercially available computerized four wheel alignment equipment (caster, camber, toe) to inspect the front wheel alignment, always position the car on a level surface with the front wheels facing straight ahead. Prior to inspection, make sure that the front suspension and steering system are in normal operating condition and that the wheels and tires face straight ahead and the tires are inflated to the specified pressure. TOE Toe is a measurement of how much the front of the wheels are turned in or out from the straight-ahead position. View Full Image When the wheels are turned in toward the front of the vehicle, toe is positive (+) (toe in). When the wheels are turned out toward the front of the vehicle, toe is negative (-) (toe out). Toe is measured in degrees, from side to side, and totaled. TOE [FRONT] Toe-in (B-A) is adjusted by turning the tie rod turnbuckles. Toe-in on the left front wheel can be reduced by turning the tie rod toward the rear of the car. Toe in change is adjusted by turning the tie rods for the right and left heels simultaneously at the same amount as follows. Standard value: Toe-in (B-A) mm (in): ±2 (0 ±0.0787) NOTE: Toe-in adjustment should be made by turning the right and left tie rods at the same amount. When adjusting toe-in, loosen the outer bellows clip to prevent twisting the bellows. After the adjustment, tighten the tie rod end lock nuts firmly and reinstall the bellows clip. Adjust each toe-in to be the range of ±1 mm . View Full Image TOE [REAR] Standard value Toe-in (B-A) mm (in): ±2 (0.0787 +0.0787) Adjust the toe-in by turning the cambolt of the rear assist arm. Left cambolt: Clockwise -> toe-out Right cambolt: Clockwise -> toe-in The variation of toe by a rotation of the cambolt: About 4.3 mm (0.17 in) CAUTION: Each toe should be within 1±1 mm (0.039±0.039 in). If the difference between right and left is not within +2mm (0.079 in), repeat adjustment. After adjusting the cambolt, tighten the nut to the specified torque. View Full Image CAMBER Camber is the inward or outward tilting of the wheels at the top. CAMBER [FRONT] View Full Image When the wheel tilts out at the top, then the camber is positive (+). When the wheel tilts in at the top, then the camber is negative (+) NOTE: Camber is pre-set at the factory and doesn't need to be adjusted. If the camber is not within the standard value, replace the bent or damaged parts. CAMBER [REAR] Standard value Camber angle (A): -10 ±30' Difference between right and left angle is within 30' Adjust the camber by turning the cambolt of the rear lower arm. Left cambolt: Clockwise -> camber (-) Right cambolt: Clockwise -> camber (+) The variation of camber by a rotation of the cambolt: About 0°0.9' After adjusting the cambolt, tighten the nut to the specified torque. View Full Image CASTER [FRONT] Caster is the tilting of the strut axis either forward or backward from vertical. A backward tilt is positive (+) and a forward tilt is negative (-). Caster is pre-set at the factory and doesn't need to be adjusted. If the caster is not within the standard value, replace the bent or damaged parts. Standard value View Full Image NOTE: The worn loose or damaged parts of the front suspension assembly must be replaced prior to measuring front wheel alignment. Caster are pre-set to the specified value at the factory and don't need to be adjusted. If the caster are not within specifications, replace bent or damaged parts. The difference of left and right wheels about the the caster must be within the range of 0°30' .
