Is this dumb or brilliant? You decide.

You are on the money with the extra main riding stiff.Doesnt help the 60 fts one tiny bit, either.
OOps your post doesnt say extra mains.However above still applys.
Oh, and with 295/50-15s I have been running 24psi for many years without abnormal tire wear. I seem to burn them off before they wear out, too. At 24 the ride is acceptable even to the point of hammering over speedbumps.I know it might sound childish,but I get a great deal of enjoyment blowing by some young kid in his fart-can tuner-car who slows down to almost zero mph or crab-crawls over them.And I make sure never to get stuck behind one.I know/I know; I should grow up already. Even remembering those times almost makes me giddy.
