Cooper Tires has LT radials that have a profile that does not balloon out. The blackwall LT radials are not obviously radials unless you read the markings. However, they ride like radials.
The tire dealer that sold me mine had no problem adding the road-hazard warranty, but the tires came with no treadwear warranty (from the factory or from the dealer). About $100 each, mounted and balanced (plus radial tubes from the dealer and free tube-stem protectors). My rims are the slightly wider rims that were provided with the RPO 6.50-16, 6-ply tires (at least in 1954).
