I got some new boots on mine recently, got PE2's on back still but i swapped the fronts for Eagle F1 GSD3, as they were £35 cheaper than PE2's and came W rated. However the priniciple reason I went for these was because of the performance in wet conditions. The PE'2 I found were very prone to aquaplaning, the GSD3 seem a much more capable wet weather tyre, possible due to the tread pattern.
