Thanks Resto -- That Discoverer STT looks like what I think I'm looking for. I have a hole-in-the-wall local tire guy who I buy all my tires from -- small guy who's doing well against the onslaught of the big-block McTire dealers because (get this) he provides great, personal service at a fair price. I will not buy tires from anyone else.
When I brought him the '49 big truck 2-piece rims to demount and remount, he said, "Looks like museum day's here again..."
But thanks for the reference!
