I would have thought that the wider tyre would have made the steering heavier. I am considering fitting power steering even with the the 195/65 R15.
I had to go from 60 profile up to 65 to get better ground clearance. The standard Plus 4 fitted with 195/60 R15 has the lowest ground clearance of the whole series of trads, often under 9cm. Given that many speed humps are 8 to 9 cm high, and sometimes 10 cm, the 65 profile gives a much needed centimeter more of clearance.

If I want to go quickly, I just jump into Sue's car, the grunt of the diesel leaves the Morgan in the dust. It out handles it, out brakes it and corners on rails by comparison and much faster and an auto, folding roof, heated seats, air conditioning ,heated seat scarf blowing warm air around you neck and good fun. Just doesn't have the same charisma of the Morgan, having said that my left leg would have swopped places with the Morgan for the Merc when inching along for miles having to keep dipping the clutch, in 3 major congestion holdups on the M6 for about an hour plus on Friday coming back.
I even investigated the possibilty of converting the car to auto, I am starting to have some leg problems, but it would seem to be a very difficult project. The people who did it for Morgan only did it for the later GDI engine which had a "fly-by-wire" throttle.
It was probably necessary so the the controller for the auto box could adjust the throttle setting when the gear changes are made.
