Ture, but on a bridge, over pass or in a shady area of the road the air temp may be 38, but the road temp can be below 32. Why did BMW chose 38 as their warning point? Who knows, it ranks up there with run flat tires, not ready for prime time hpfp and the euro beek nose (I actually do know this one) as unknowable BMW quirks. N4S
