I have just had a Contiforce SM tyre fitted to the front wheel in place of the Ageing and worn out Pirelli but now the bike weaves very badly at 70mph +. Its most prominent after exiting a bend as the bike comes back upright its weaves until I back off.

Previously I had the front Pirelli with a rear Contiforce SM and experienced no weaving at all at any speeds.

I am running the tyres at 30/30 psi.

Anybody else experienced issues with these tyres and overcome them?
