I fitted a set of Triangle Talons to the back of mine in November at a cost of £80ish and have done about 5k on them so far.

In that limited amount of time I would say that they are a great tyre for the price - I don't think they are very noisy and appear to grip well in most conditions, they even handled the snow remarkably well.

My fronts haven't got long left so I shall definitely be splashing out £80 on another pair to replace them!
