im in need of some new rubber and i want some good life out of these. im not riding aggresive twisties that much anymore(saw a couple people eat it this year in the twisties already) so i dont need anything super sticky. i hear the avon 45/46 for the rear and the more sport oriented 49 in the front would be a good combo. any opinions? basically i need a set of tires that will last me the longest while still providing enough grip for some moderate twisty riding.
