Tyre profile, what effect if any on steering?
(OP)
What effect does the profile/shape of a tyre have on steering a bike? For instance, my tyre is flat with rounded edges , and a sportsbike tyre is very rounded!

It will also help traction as the rounder profile will have a larger contact patch.

PS---For those of you who are old enough to know, I use 19" and 21" wheels because the original 20" are impossible to find.

I've been looking for a roadworthy 300-20 trials-universal pattern tyre.. still am.
evelrod, if you're about, I'd be interested to know if you detect any difference in handling on the road with a larger diameter front wheel, if not running a rear 400-19? Were your Norton's original overall tyre diameters the same at both ends?

My '48 Norton International/ES-2 is the bike that Australian World Trials Champion Bill Young rode in the early 50's. It was restored in WA for $9000AU and shipped to the U.S. a few years back and it was already converted to the 19 and 21's. Actually I rather like the 21 inch wheel as it rolls over the bumps that the rather primitive (by today's standards) front suspension does not handle. The rear 19 is the same overall dia as the original 20 and bunches cheaper to purchase. The bike cruises at 60/65 mph and handles well on smooth roads---at least as well as a 65 year old wants to push it!
As to the 20's being the same size, I would assume so as most all Nortons of that era were so equiped as I recall.

20s were a popular size back then but the first I knew of them was as barely a teen-ager cutting my riding teeth in the late sixties on a BSA C11 which had 20s fore and aft. Still pretty keen on 'em.
The 20s, not the C11..
