Dennis, I see no reason why you couldn't experiment with slightly higher front
pressures. I remember reading years ago (and wish I could again locate the
source) that auto manufacturers often tended to "recommend" tire pressures that
would normally lead to understeering conditions at the limit rather than
oversteering. The reasoning was (is still? Explorers and Firestone tires
notwithstanding) that, for the average driver, a bit of front-end plowing was
easier to deal with than a tail trying to swap ends with the front.
FWIW, I always rather liked the Michelin XZX tires back in my Volvo 144 days.
They were, IMO, a great improvement over the ZX tires. Of course, I still have
"original" Michelin "X" radials on the Mayflower, said tires salvaged from a
TR4. Even those vintage treads are a notable improvement over the cheap
bias-plies that were on Priscilla when I first got her! Seems worth a mention,
since Mayflower and TR share many suspension components! :-)
