We have grown new potatoes in tires a bunch of years. When you add a tire make sure you fill it in good but do not pack the dirt to much. I have gone 6 high with huge tractor tires.
As far as building up soil I like to get a bail of scrap paper and till it into the soil. As far as getting a bail try news paper plants. 3 years ago was the last time I got some and it was $20 a ton.
