Sticky racing type tyres on older cars with high centres of gravity and
narrow width track are a bad combination.
Competing this weekend in a pre 1960's racing meeting a 1930 M type MG took
a couple of rolls on a corner which, had it not been for the sticky race
tyres it was wearing, the worst which might have been expected was a spin
out.
Another car rolled - a 1932 Morris Austin Special. Different cause however
when the king pin collapsed the front wheel buckled under and the car
flipped.
Both drivers to hospital. Both saved by roll bars.
Apart from the tendency to roll the stresses exerted by these sticky
compound tyres were never factored into the design of our early MG's.
In 90 minutes of track time with cross ply tyres the worst that happened to
me all day was 3 or 4 broken spokes.
