Hi Heinz, Interesting subject. I changed my 165/80 R15 Continentals, which were standard on my 4/4 2014, to Vredestein Sprint Classics 185/70 R15 in 2017. I had to repaint my rear fenders 2 years later, because of the damage caused to the outer ring. I just moved the fenders 1 cm outwards, which was easily done, because the factory makes rather big holes to mount the fenders. You managed some problems with balancing, which I also have. Some wobble around 80-90 km/hr. I have now 53000 km on the clock, so not long before tire change will be necessary. You mentioned the Nankook tires. I checked the Dutch Automobile Association (ANWB). Their verdict on these tires was not very good.
Test result: Hankook Kinergy Eco 2 K435
New model of this brand from South-Korea. The Kinergy is the 'green' product with the emphasis more on fuel consumption, mileage, and comfort than on sportivity
+ Good on dry road surfaces and low fuel consumption.
- Clear imperfections on wet road surfaces (with insufficient road handling).
These are not specs you're looking for for your Morgan.
