As it is, I wonder how the old 155R15 tires as available for classic Beetles and 2CVs fare for r.r.?
2CVs have 125R15 tires and they have terrible rolling resistance. I had 145R14 tires of similar construction on my car for tests and the rolling resistance was very bad. The tires were nearly hot after a trip (sign of much deformation) wereas my LRR tires were slightly above ambient temp. Manufacturers don't put much effort into RR for these tires because fuel efficiency is not that much of a concern on older cars. The criterion is to keep the old tread design, not favorable for LRR.
