I, too, am surprised you are looking at 4.50x19s for a Rosengart; that's the standard size for a Riley 9, which is a much bigger and heavier car. You won't get an Avon sidecar tyre in that size either!
Longstone 4.00/4.50s seem to be extremely popular with Riley owners, and my brother's Frazer Nash is also quite happy on them, so if you do want 4.50s I think you will be happy with them. If you really mean 3.50x19s, then I am happy to join the recommendations for Longstones, too - they are more pliable than the (very old) Avons which I replaced, and I was struck by an immediate improvement in both ride and handling. I suspect they will wear out more quickly, but with the current recommendation to replace tyres after six to eight years, they willprobably still have tread left when it's time to replace them.
Having said that, I know Dave Mann is not a fan, and as it happened after a conversation with Dave I did experience an unnerving experience when the car hopped sideways over an undulation in a manner I didn't expect. Was it the tyres?I don't know, but ...
