had the cross's on mine for nearly 2years now. quiet, never stuck and still plenty of tread on them
but what ever you do ,do not mix them with syncrones
how about Syncrones and Michelin 4x4s? I've got a pair of each ready to go on, but can probably get my hands on another pair of 4x4s if there's some big compatibility issue. Syncrones better front or back if I go ahead with the two pairs?
