I work for a large transport and bus builder in South Africa. We are currently looking to source 12R22.5 and 315/80R22.5 tyres from a reputable and stable company who will be able to handle all sourcing requirements from factory to our doorstep. We currently use around 500 tyres per month hence we are seeking to deal directly with a company thus reducing our cost and the need to go through a third party. We will thus require that the supplier source, freight and deliver the tyre to our doorstep. Could you please send me a detailed costing per tyre to source, freight and deliver.
