I’m perplexed, as to the rational that the material’s heat retention capacity is why aluminum wheels work better than magnesium in cold conditions. The thermal transfer coefficient is higher for aluminum alloy (167 W/m^2K) than magnesium alloy (53W/m^2k). The higher the coefficient number the better the heat transfer, so it would seem that given every other parameter being the same between wheels the aluminum wheel would run cooler. Is there another reason why “aluminum wheels” perform better in cold weather or I’m all wet 
Could it be construction of the wheel?
