I do not run a snow/ice tire but a summer tire as I believe that is where the best traction is found. I do not use a run flat and my weight is over 300 lbs. My summer tire does not squirm even a little at 42 lbs. In fact you have to really pay attention to realize it might be a little different feeling than a MT. It is perfect and looks great also, much closer to a MT in looks than many I've seen. This is my second CT on a bike and I have tens of thousands miles, mostly on one tire on a VTX. Go back and read some post of people with many miles under their belts and you will see that they do not use a run flat or a snow/ice tire. You have now tried an untried tire with poor results, if you give up on that one try something that people have already found good results from.
