TRD Pro Wheel & AT Tire upgrade

When this is added as an upgrade on an SR or SR5 do different dealers or factory use different brand tires or is there a Particular brand/model that most use?

 

Generally speaking vehicle manufacturers contract large quantities of tires from tire manufacturers before the production of a vehicle starts. Any factory added upgraded tire package would be with a specific tire brand and model. If a dealership is adding their own upgrade package this limitation would not apply and theoretically they could use any tire they want however for the most part they would select a widely accepted and quality A/T tire.
