The City of Mobile seeks a vendor to provide cold‑process retreading services for large‑truck and trailer tires. The contractor must use Bandag, Goodyear Vipal, or an approved equivalent, meet strict tread‑depth specifications (26/32″ radial highway, 21/32″ radial logger lug), and guarantee a seven‑calendar‑day delivery window from order receipt. Weekly pickup of tires set aside for retreading is required, with the retreaded tires returned to the Municipal Garage within seven days. Quality assurance includes on‑site inspection rights and the need to make recapping facilities available to City personnel. The contract is a sealed, all‑or‑none bid with a 6‑month base period and optional extensions up to five additional 6‑month terms, and includes a discount provision for payment within 20 days of receipt.
