Tires â Retreading is less expensive than new tires and is a large portion of this cost. Although mere pennies per mile, an average tire can cost over $250 and annual tire expenses can exceed $4,000 ($0.03 per mile), enough to purchase 16 new tires annually, but still not enough to replace every tire of an 18-wheeler.
To Correct Forward Head Posture, the muscles which need to be stretched comprise of: 1  Upper cervical (capital) extensors: Semispinalis capitis, splenius capitis, longissimus capitis and suboccipital muscles. 2  Lower cervical flexors. Sternocleidomastoid muscle, medial and anterior scalene muscles.
These include the buccinator, masseter, temporalis and pterygoid muscles. Below the muscles of your face are neck muscles that help support and move your head. These include the sternocleidomastoid muscles, which flex your neck, move your head from shoulder to shoulder and turn your face from side to side. Moving around to the back, we have axial muscles of the spinal column.
