If the collector has a direct view of the tires, you will being heating the tire through radiant heating. At the same time you could be cooling the collector via convection cooling from air flow through the hole in the liner. Always keep in mind, heat transfer is always from hot to cold, in addition, radiant heating varies with a high exponent of the temperature.
