BFG Comp T/A

["MalcolmCox" <malcox@sonic.net>]

I just ran BFGoodrich Comp T/A at a HMSA club event at Laguna last
weekend.  Very much enjoyed them.
However, for the first time, I noticed significant understeer at the
turn 2 hairpin.
Just kept turning the wheel and flooring the gas, along with scary
rumbling from the front end.
Fortunately, the track was just wide enough!

I am using 30 psi front 28 psi rear, cold.
Perhaps I need to change tire pressures?
Anyone care to make recomendations on tire pressure for my MGA?
