For those many Seven owners who do not normally reach or exceed 50 mph I doubt if there is much heightend risk of consequent accident because of sudden deflation, esp if you keep an eye on. Non sport Sevens are seldom cornered near adhesion limits because roll over limits antics, so adhesion hardly an issue. (For years my car was run on smooth used m/c tyres). But hard old tyres are difficult to fit and from all accounts handling is poor, notably wander, esp cf very pliant walled moderns. I suspect the moderns behave more like radials and camber steer due local variations in tilt of the road surface is reduced.
The age limits on "moderns" have a point but I have run old cars for decades and hoarded used radial tyres 30+ years old often used. Infinitley better that the original crossplies of any age. No problems at regular 100 kph. Decades ago a work colleague addicted to high speed had the treads succesively explode off old original radials on an NSA Wankel but at 80 mph.
