BBQ Bike

i know that with a project like this weight shouldnt really be the top consideration but i also dont want to be riding a tank around! so any other ideas how i could reduce the transfer of heat to the wheel?
i was thinking of some kind of flame retardant material i can get hold of nomex any ideas if this would do the job or should i find an insulator to go with it?

Get your mates to carry the coal, meat and man cooking tools etc.

Nomex should work fine as a heatshield me thinks, no need for any additional insulation.
