OK, without sounding like I'm after a free set of TKC for my bike (although that would be nice Continental, having bought seven of them in the last six months x) I'm not sure it's necessarily the tyres, as I've not experienced any weaving with them myself...

I run them at 30psi and they are pretty damn good. You might want to check your rear wheel alignment, and also the wheel bearings, just to eliminate those from the equation?

(ps. 140 rear this time please Conti x)
