Tender Summary: 315/80R22.5 New Tyres and Retreading Services

Objectives

The primary objective is to secure a qualified service provider for the supply, delivery, fitting, and balancing of new tyres, alongside the retreading of existing tyre casings, specifically for the municipality’s articulated bus fleet. The procurement aims to ensure continuous operational readiness of public transport vehicles while adhering to municipal supply chain governance and national preferential procurement mandates.

Scope

The contract covers two distinct deliverables:

• New Tyres: Supply, delivery, fitting, and balancing of eighty (80) units of 315/80R22.5 dual-purpose tyres, exclusively designated for articulated buses.
• Retreading Services: Processing of fifty (50) tyre casings (315/80R22.5), including stripping old tread and applying new tread, strictly for the rear axles of articulated buses.

All tender responses must be submitted electronically. Quoted prices must remain valid for a minimum of thirty days from the tender date. Award is contingent upon successful registration on the municipal supplier database.

Technical Requirements

• New Tyres: Must conform to the 315/80R22.5 dimension and be rated as dual-purpose for articulated buses. The manufacturer make, brand name, and delivery period must be explicitly stated on the quotation. Brochures or physical samples may be requested during evaluation.
• Retreading: Must employ an M48 tread pattern or equivalent, approved specifically for rear axle use on articulated buses. The scope includes complete tread stripping and new tread fitting. The exact tread pattern and delivery timeline must be specified. Supporting documentation or samples may be requested.
• Compliance: Bidders must comply with the General Conditions of Tender and Conditions of Purchase. Non-compliance with electronic submission rules or supplier registration requirements will result in disqualification.

Skills Requirements

The tender does not explicitly mandate formal certifications, but providers must demonstrate industry-standard competence in heavy-vehicle tyre logistics and refurbishment. Essential capabilities include:

• Proven experience in sourcing and distributing commercial-grade dual-purpose tyres that meet strict dimensional and load-bearing specifications.
• Certified retreading facility operations capable of inspecting, repairing, and applying new tread patterns to high-stress tyre casings.
• Skilled mechanical technicians proficient in safe tread stripping, fitting, dynamic balancing, and delivery of heavy vehicle wheels.
• Administrative proficiency to navigate electronic procurement platforms and align with municipal regulatory and reporting frameworks.

Explanation of Key Terms

• 80/20 System: A preferential procurement scoring model where 80% of evaluation points are allocated to price competitiveness and 20% to socio-economic development objectives, such as supporting historically disadvantaged enterprises, local economic participation, and small business growth.
• Dual-Purpose Tyres: Heavy-duty tyres engineered to deliver balanced performance on both paved highways and unpaved or light-off-road surfaces, suitable for municipal buses operating across mixed terrain.
• Retreading: A sustainable refurbishment process where worn but structurally intact tyre casings are cleaned, inspected, repaired, and fitted with new tread rubber, extending product lifespan and reducing environmental waste.
• Strip & Fit: The mechanical procedure of removing the degraded original tread from a tyre casing and vulcanizing a new tread pattern to it, followed by mounting the refurbished tyre onto the wheel assembly for immediate deployment.
