It's time for a new set of tires. I ride and 03CR250 and will be riding a lot of mud and sand with some slick hard packed mud and some loam thrown in. I'm pretty much stet on the Dunlop 773 for the rear as the performance I've had with this tire in the mud is amazing. Up front I've only had experience with the 756 which is good in the mud but slides a lot. It feels like it is underperforming when mated to the 773 rear. What I would like to know is how the 773 front and Michelin S12 front compare with the 756 front in mud and sand. I am only concerned about those 3 tires and would like to hear from anyone that has experience with them. Thanks.
