Gary, You are going to get every opinion on this topic from the IML group that is to be had by anyone. Many advocate that the cars were designed for old style tires, so that is what they should have. Some have claimed that putting radial tires on Imperial wheels from the '60s and earlier causes the rims to crack, or ruined their cars. I always think safety first, so if one believes that using modern tires on an older car is going to be dangerous, than they should go with what they believe. I have had excellent luck with radials on '60, '62, '63, '65, and '68 Imperials. I drove my '65 Imperial with several different sets of both new and used radials over the years totaling over 100,000 miles. The current set of radials have been on it for 15 years and seem to be fine. I have never broken a wheel or suffered any road shock, vibration, or handling problems from them. In fact, to the contrary, from the first time that I experienced radial tires on an torsion bar suspension Imperial I have believed that they enhance the superlative handling and cornering characteristics of those cars. My '65 Imperial has had Perrelli, Uniroyal (2 used sets), and finally the current Goodyear Arrivas which are now quite old and out of production. Not everyone agrees with this so you will have to make your decision once everybody has posted. On my '48 L.C., and my '55 and '56 Imperials I have had, and plan to keep the old style tires. Those cars seem to handle fine with those old tires. I will never say never, and since I have seen some very attractive new radial white walls, I may try them someday on the older cars. I have believed that "cheap" radials are not a great idea since they can come apart, like any other cheap tire, but that the steel belts can add to the sometimes disastrous outcome. I heard of a man who lost a '49 Cadillac to a roadside explosion after a disintegrating rear radial tire ruptured his gas tank, which was further exacerbated by sparks from the shredded metal coming in contact with fuel and vapors. Cheap tires are never a good bargain. All tires need to be properly maintained.
