yeah what he said: i want to sipe mostly for safety in wet conditions, when comes that big puddle i cant avoid or the like.. but i like the other benefits also mentioned too.
(it does seem wrong to cut up your tires, but it really is for the better - i'll just have to accept that and view a MT as my blank canvas

think how much hockey would suck if we had siped hockey pucks - essentially, to me a Mud Terrain tire is like running on hockey pucks).
cooler temps, better tread life, less noise maybe, Better wet and freezing traction and to me it essentially gets a MT tire better performance and more like a beefy AT tire.
This video pretty vividly depicts the added grip under slippery, wet conditions:
235 some odd collisions a day happen in BC at intersections. (i used to be a traffic consultant) That's where I'm most careful while driving. Mountain Passes, I'm obviously not looking to break any laws, but last time i checked it didn't even snow here on the island, so by the time the bureaucrats and ICBC make any new law, im sure global warming will have something far more varied and dangerous than just mountain snowflakes
My question currently is how much is too much siping? Tire shop sipers only sipe at one rate, and that's like a sipe every 1/8th or 1/4 inch. is this what you did cruiser?
Performance on all fronts. Improved traction on roads and offroad. I drove my swampers to Alberta about 4 times in the winter with
400 HP 351W and ran through the pass
My friend recently got rid of his BFG AT KO's for the KO2 (heavy diesel truck with a camper on) and he did not like them very much. I'd met up with him in Seattle at Wintergrass and he said they are too sticky on the highway, didn't seem to want to relax and roll along and were too grippy and responsive to steering inputs on the hwy and this was driving in winter from Fernie BC, down to Seattle, from snow to dry to wet weather i assume.
What i'm thinking i'll do is sipe them myself, and i'll shoot for less siping than a KO2 and around the same as the old KO's had.
