General consensus seems to be that mid to high 20's is a good starting point for road and cruisin' pressures.
For track use use a "higher" pressure
an aside ..... even though they are in their late 70's my folks still take their MG-GTB out for track days. Run 28 all around for the street but up that to ~40 for the track. That takes most of the 'squish' out of the tires .....
I don't think anyone can say 'thou should run X pressure in thee tyres' as there are just too many differences between tyres, roads, cars and even our butts. Everyone can say what works for them and each of us then goes from there to find what works for us.
Something I've been thinking about while reading thru this .... BFG's have a reputation for not being the most round of tyre, nor the most balanced within their construction. Those who used a Hunter load balancer on those BFG's noted an improvement in steering, which no pressure adjustment would fix.
I'm looking forward to running a set of BigLetters - maybe with 4 wooden blocks and low-profile jack I can borrow Jamo's while he's not looking
