Yep, you read it right, car tires.
Allison has managed to eat as much as 50 tires in the last six years.
“The rubber tire pieces taste really chemically, like a shock to your taste buds. It’s amazing,” says Allison.
The 19-year-old sits around the house with a bowl of little rubber pieces by her side, snacking on the tiny morsels of synthetic material much like it is a bowl of popcorn.
Her addiction has taken over her life and on a daily basis, Allison can eat as much as two feet of rubber, which equals about 14 pounds per month.
“The texture of the rubber pieces is like beef jerky. It’s a work out for your jaw,” explains Allison.
